Virtual currencies are a contemporary form of private money.
Thanks to their technological properties, their global transaction
networks are relatively safe, transparent, and fast. This gives them
good prospects for further development. However, they remain
unlikely to challenge the dominant position of sovereign
currencies and central banks, especially those in major currency
areas. As with other innovations, virtual currencies pose a
challenge to financial regulators, in particular because of their
anonymity and trans-border character.

• Virtual currencies (VCs) are a contemporary form of private money. Thanks to their digital form and
the use of Blockchain technology (in many, but not all, cases), the transaction networks of VCs are
relatively safe, transparent, and fast. Unlike their 18th and 19th century paper predecessors, VCs
are used globally, disregarding national borders. However, as with any money or financial asset,
investments in VCs are not without risk. VCs may be subject to fraud, the bankruptcy of the issuer
or intermediary, or speculative bubbles and bursts, among others.
• In April 2018, there were more than 1,500 VCs; however, only a few recorded meaningful market
turnover and capitalisation. Bitcoin, the first VC, created in 2009, remains a leader among them. The
VC business has seen continuous development in terms of number of VCs, number of transactions,
and market capitalisation. However, as long as major trading platforms and financial intermediaries
do not accept payments in VCs, their transactional role will remain limited and they will fulfil mainly
the third function of money, the store of value—that is, they will serve as one of many investment
• Similar to previous incarnations of private money, VCs face the challenges of gaining market and
governmental recognition as a means of payment, building public trust concerning their stability,
and achieving sufficient network externalities related to their use. While governments and central
banks will unlikely accept them as an official legal tender in individual jurisdictions, the question of
market recognition remains open, and the rapid expansion of Bitcoin and other larger VC projects
worldwide indicate that it may happen (to some degree). And unlike previous incarnations, issuers
of contemporary private money are able to ensure a transparent global network for circulation, a
credible algorithm for the creation of the VC, and a transaction mechanism that is relatively safe,
fast, and inexpensive.
• Despite their technological advances and global reach, VCs are far from being able to challenge the
dominant position of sovereign currencies and the monetary policies of central banks, especially in
major currency areas. However, in extreme cases, such as during periods of hyperinflation, financial
crisis, political turmoil, or war, they can become a means of currency substitution in individual
economies.
• Financial regulators may dislike VCs because of their anonymity or cross-border circulation. They
tend to fear that VCs will facilitate money laundering, the financing of illegal activities, tax
avoidance, the circumvention of capital controls (in countries where such controls are in place),
and fraudulent financial practices. Such concerns may be legitimate in some instances but must
not be generalised. In most cases, transactions in VCs result from the free business choices of
economic agents and, therefore, should be treated by regulators as any other financial transaction
or instrument—that is, proportionally to their market importance, complexity, and associated risks.
Given their global, trans-border character, it is recommended that regulations concerning VCs be
harmonised across jurisdictions (which is far from the case now). Investment in VCs should be taxed
similarly to investment in other financial assets.
Less than a decade has passed since the development of Bitcoin, the first private decentralised digital
currency with a global reach. Despite many sceptical opinions, this experiment has survived, enjoys
broad popularity, and has found many followers. Today Bitcoin is not alone; there are more than 1,500
other virtual currencies (VCs), but only a few record meaningful market turnover and capitalisation.
Bitcoin remains the leader among them.
Initially, Bitcoin and other VCs drew little attention from economists or monetary and regulatory
authorities. VCs were considered a niche phenomenon—a sort of technological folklore—that could
disappear any day. They were largely analysed and propagated by IT specialists.
However, more recently, the situation has changed radically. Because Bitcoin did not disappear and, on
the contrary, has continued its expansion and found followers worldwide, it has become a popular
subject of discussion among economists, financial market specialists, and even politicians. Public
figures are now expected to offer opinions on the topic. This increasing interest in VCs was partially
underpinned by the rapid build-up of the Bitcoin financial bubble in 2017 and its subsequent burst in
early 2018.
Responding to the request of the European Parliament's Committee on Economic and Monetary
Affairs, this briefing paper presents an analysis of the phenomenon of VCs (and how it is seen in
economic literature and public debate) and their potential impact on both financial markets and
monetary policy, as well as on the supposed central bank monopoly on issuing money.
Our study will begin with an overview of the economic and technological characteristics of the VC
phenomenon and will then provide a brief history of VCs, an analysis of their advantages and
disadvantages, and a review of the regulatory approaches to VCs in various jurisdictions (Section 2).
Section 3 provides a discussion of the potential impact that VCs may have on monetary policy and the
future role of central banks. To better understand the factors which may determine this impact, we
offer a brief historical overview of the era of free banking and private money in the 18-19th centuries
(Subsection 3.1), followed by an analysis of the legal instruments regulating the use of money, the role
of network externalities, and currency substitution. Based on our analysis in Sections 2 and 3, we
summarise the main findings of our study in Section 4.
In our analysis of VCs (mainly in Section 2), we had to rely, to some extent, on information and data
presented in various online sources. However, whenever possible, we attempted to cross-check this
information to ensure its accuracy. In addition, we reviewed the existing literature on monetary history,
private money, VCs, Blockchain technology, and central banking, among others. In Section 3, we used
data from the International Monetary Fund (IMF) Monetary and Financial Statistics database and the
US Federal Reserve System.
Our working hypothesis is that VCs are a contemporary form of private money and, as such, share
certain historical advantages and disadvantages. That is, they will unlikely challenge the near-
monopoly position of central banks in issuing money and the monetary policies conducted by them,
at least in the near future. Nevertheless, due to their technological characteristics, such as their digital
form, the possibility for cross-border circulation, network transparency, and a predetermined algorithm
of issuing currency units, they have a better chance to survive and develop as compared to their
predecessors in the 18th and 19th century.
Overall, in our analysis we try to take a middle ground between the optimism and excitement of the
techno-enthusiasts and advocates of private money and the scepticism or even hostility of those who
see VCs as product of monetary mania or utopia and a convenient instrument for money laundering,
fraud, and other illegal activities. We believe that whether one likes them or not, VCs will remain a
permanent element of global financial and monetary architecture for years to come.
THE POTENTIAL IMPACT OF VIRTUAL CURRENCIES ON
In this section, we present the definition and economic characteristics of VCs (Subsection 2.1), their
technological features (Subsection 2.2), the history of their development (Subsection 2.3), an analysis
of their advantages and disadvantages (Subsection 2.4), the evolution of the regulatory approach to
VCs in major financial jurisdictions (Subsection 2.5), and the limits of such regulations (Subsection 2.6).
2.1. Definition and economic characteristics of VCs
There is no one agreed-upon definition of VC. For example, the European Banking Authority (EBA)
defines a VC as a "digital representation of value that is neither issued by a central bank or public authority
nor necessarily attached to a fiat (conventional) currency, but is accepted by natural or legal persons as a
means of exchange and can be transferred, stored or traded electronically" (EBA, 2014, p. 7). The European
Central Bank (ECB) defines a VC as a "type of unregulated, digital money, which is issued and usually
controlled by its developers, and used and accepted among the members of a specific virtual community"
(ECB, 2012, p. 14). According to the definition of the Financial Action Task Force (FATF), "Virtual currency
is a digital representation of value that can be digitally traded and functions as (1) a medium of exchange;
and/or (2) a unit of account; and/or (3) a store of value, but does not have legal tender status (i.e. when
tendered to a creditor, is a valid and legal offer of payment) in any jurisdiction". (FATF, 2014, p. 4).
VCs have no intrinsic value in the sense that they are not linked to any underlying commodity or
sovereign currency. However, in this respect, they do not differ from most contemporary sovereign
currencies. VCs' value emerges solely from the ability to transfer it from one place to another inside the
particular VC's "electronic ecosystem", and relies entirely on trust, as there is no legal way of forcing
anybody to accept it as a means of payment.
The term "virtual currency" might be misleading, suggesting that a VC is a sovereign currency issued
by a public authority such as a central bank and is officially recognised as a legal tender in at least one
jurisdiction. 1 Instead, as we will discuss further in this paper (Subsection 3.1), they represent a form of
private money.
Similarly, the question of whether VCs share characteristics of full-fledged money also remains
controversial. For example, Söderberg (2018), the Bank of Canada (2014), the Bank of England (2014),
and Yermack (2013), among others, argue that VCs do not satisfy the traditional definition of money
discussed in economic literature. In particular, in their opinion, they do not meet the conditions
outlined by Jevons (1875, Chapter 3). According to this definition, money shall fulfil three basic
functions: be a means of payment, a unit of account, and a store of value. Critics argue that VCs serve
as means of payment to a very limited extent, as only a very limited number of merchants accept them,
the number of transactions is still negligible compared to sovereign currencies, salaries are not paid in
VCs, and no known government accepts them as a legal tender or unit of account. They also fail to
effectively serve as a store of value because of an enormous volatility of their purchasing power (see
Subsections 2.3 and 2.4). On the other hand, one cannot exclude the possibility that a number of users
and transactions will increase to the extent that VCs will become a fully-fledged substitute of sovereign
currencies in the future. We assume that VCs have potential to serve as full-fledged private money
regardless of their future share in the overall volume of transactions and financial assets.
To best of our knowledge, at the moment of writing this paper (May 2018), there is no VC recognised as a legal tender in
any jurisdiction.
VCs are often referred to as "cryptocurrencies" because the majority of VCs rely extensively on use of
cryptographic algorithms (Subsection 3.2). However, in our opinion, this term is misleading and may
have a pejorative meaning, so we will not use it in our paper.
In summary, VCs share the following characteristics:
• They are form of private money usually created in decentralised way (which is not a new
phenomenon in economic history—see Subsection 3.1);
• They exist exclusively in digital form;
• Thus far, most VCs have been based on Blockchain technology 2 (see Subsection 3.2), but perhaps
also other technologies can be employed in future; and
• Most of them have a global character—that is, they work across national borders.
2.2. Technological features of VCs
As of April 2018, over 1,500 VCs existed, and this number is rapidly growing. We are unable to discuss
here the details of the construction of all of them. While most (including the most popular—Bitcoin)
use Blockchain technology (see below), the particular features of some VCs can differ significantly.
Moreover, it is impossible to predict the future technological innovations that may be used by the
creators of new VCs.
An important feature of VC transactions is that units of VC are sent directly from one place in the
electronic ecosystem to another, without the involvement of any intermediary (e.g. financial
institution). Units of VC are usually stored in electronic addresses that have unique public IDs. Multiple
addresses can be combined into "e-wallets". VC transactions are typically chronologically recorded in
a public decentralised ledger, often referred to as "Blockchain". The ledger consists of "blocks" that
contain records of the past transactions. The Blockchain is maintained by the community of so called
"miners". Miners are the people who supply the computational power necessary for processing
transactions and keeping the system functioning. In exchange for their services, miners get small
amounts of VC units, either in the form of a voluntary fee or newly minted units of the VC.
Another important feature of the currently existing VCs is that most of them are not issued by any
individual entity (e.g. a central bank). New units of VCs are created in a decentralised manner by the
community of miners. The supply of new units of VC is kept under control thanks to the use of
cryptographic algorithms. The easiest way of explaining how this system functions is to describe a VC
transaction process step-by-step. Below we present an example of a transaction process using Bitcoin,3
which was the first and remains the most popular VC. As mentioned above, most other VCs have similar
characteristics—that is, in most cases the transaction process looks similar.
The Bitcoin transaction process uses cryptography to verify transactions, process payments, and
control the supply of bitcoins (Badev and Chen, 2014, p. 7). Cryptography has been used since antiquity
to secure information; but in this particular case, it serves to create and control the supply of units of
currency. The concept behind cryptography is that a message is encrypted using a certain algorithm in
order to make it unreadable for anybody who does not have a key necessary to decipher this message.
A Bitcoin transaction is basically such an encrypted message that facilitates a transfer of bitcoins from
the sender's electronic address to the recipient's electronic address.
A notable exception is Ripple, which uses a unique distributed consensus mechanism—see Subsection 2.3.
Bitcoin, written in upper case, refers to the transaction system, whereas bitcoin, written in lower case, refers to a unit of
virtual currency.
Bitcoin employs two cryptographic schemes: digital signatures and cryptographic hash functions. Digital
signatures ensure that: (1) the recipient can verify that the message came from a particular sender, (2)
the sender cannot deny sending a message, and (3) the message has not been tampered with.
Cryptographic hash functions enforce discipline in writing transaction records in the public ledger.
Both of these schemes existed before the creation of Bitcoin and were widely used to secure
commercial and government communications (Badev and Chen, 2014, p. 7).
The Bitcoin system functions according to a set of rules known as the Bitcoin Protocol. When person A
wants to pay a certain amount of bitcoins to person B, payment instruction is placed in the system,
along with other payment instructions.
Miners validate payments and record them in a newly created block by solving a computationally
demanding mathematical problem that is created and specified by the Bitcoin Protocol. Miners get
compensation for their services in two forms: fees and freshly minted bitcoins that are created in the
process of validating the transactions. Miners compete with each other, as the compensation is paid to
the first miner that solves the problem, meaning that the system favours miners with the strongest
computational power.
Figure 1: Overview of the Bitcoin structure
Source: Söderberg (2018).
Fees are voluntary, but as they attract miners to particular transactions, users can compete for miners'
computational power and speed up the validation of transactions by offering higher fees. In addition
to fees, miners receive bitcoins that are created in the process of the validation of transactions. The
system is constructed in such a way that the amount of newly created bitcoins is constantly decreasing,
meaning that the relative importance of this form of compensation will fall and fees need to increase
over time.
The creators of Bitcoin set the maximum number of bitcoins to 21,000,000. When this number is
reached, no more bitcoins will be created and the only remuneration that miners will receive will be
the fees. When the transaction is validated by the miners, it is added to a new block that later is added
to the Blockchain (public ledger). Figure 1 depicts the structure of a Bitcoin transaction.
One of the features of VCs is a greater degree of anonymity of transactions compared to traditional
banking services. Although all transactions are recorded in a public ledger, they are linked to electronic
addresses, not private or legal persons. As long as the owner/user of a particular electronic number is
not disclosed, the transaction remains anonymous. It can be compared to writing a book under a
pseudonym: as long as the pseudonym is not linked to the author, the author preserves his or her
privacy. However, once the link between the pseudonym and author is established, authorship of all
books published under the particular pseudonym is revealed. In the case of transactions using VCs,
once the owner of particular electronic address is identified, all past transactions linked to this address
(and, with some effort, also to other electronic addresses in the same e-wallet) can be linked to this
person, as they were recorded in the public ledger. There are many techniques to try to preserve
anonymity, and one of the simplest is to use a different electronic address for every transaction.
Goldfeder et al. (2017) argue, however, that none of these techniques are perfect.
2.3. Bitcoin, Ethereum, Ripple, and others—the history of the
development of VCs and their markets in 2009–2018
Among the over 1,500 VCs existing in April 2018 (see Subsection 2.2), most are new and have negligible
market capitalisation. Therefore, we will concentrate on the five VCs with highest market capitalisation
as of 20 April 2018 (Table 1).

2.3.1. Bitcoin
Bitcoin was the first VC, created in the beginning of 2009 by an unknown person or group hiding
behind the pseudonym of Satoshi Nakamoto (Söderberg, 2018). Initially, it did not gain much of
10 PE 619.009
attention from the public and was mostly used for online gambling, especially through the internet
service named "Satoshi Dice" (Badev and Chen, 2014, p. 19).

PE 619.009 11
In the beginning of 2017, demand for bitcoins started to grow rapidly, resulting in the exponential
growth of its exchange rate to nearly US$ 20,000 (see Figure 2) and market capitalisation of over US$
300 billion (see Figure 3). The behaviour of Bitcoin's exchange rate clearly displayed features of an asset
bubble, which eventually burst on 17 December 2017, resulting in rapid depreciation (by 64.7% over
less than 2 months). However, in April 2018, it remained the most popular VC with nearly 17 million
units in circulation and market capitalisation of over US$ 140 billion.
The use of VCs in day-to-day transaction remains negligible. During 2017, the number of Bitcoin
transactions in the world was, on average, around 275,000 per day, compared to over nine million card
transactions per day in Sweden (Söderberg, 2018) and 295 million traditional transactions per day in
Europe in 2014 (EBA, 2014, p. 7). The number of confirmed Bitcoin transactions is shown in Figure 4.
Figure 4: The number of confirmed Bitcoin transactions per day, 2009-2018

2.3.2. Ethereum
The VC with the second-largest market capitalisation, as of 20 April 2018, is Ethereum. Ethereum also
uses Blockchain technology to process transactions but is different to Bitcoin in several aspects
(Madeira, 2018):
• Block time in Ethereum is shorter than in Bitcoin (14-15 seconds compared to 10 minutes) which
allows for faster transaction times;
• The number of newly created bitcoins decreases over time, while in the case of Ethereum, a
constant number of new currency units is infinitely created every year;
• Ethereum has a different method of costing transactions;
• Ethereum was crowd funded while Bitcoin was released. As a result, early miners own most of the
bitcoins that will ever be mined, while in the case of Ethereum, the fraction owned by miners
increases over time; and
• Ethereum discourages centralised pool mining and encourages decentralised mining by
individuals using their computers.
Ethereum started being traded in August 2015 and, since its launch, the exchange rate against the US$
increased over 200 times. From 19 April 2017 to 19 April 2018, its exchange rate increased by 1076%,
from US$ 48.31 to US$ 567.89. The highest exchange rate was recorded on 13 January 2018 when one
unit of Ethereum cost US$ 1,396.42. As shown in Figure 3, the market capitalisation (and the exchange
rate) of this VC are highly correlated with those of bitcoin.
2.3.3. Ripple
The VC with the third-largest market capitalisation, as of 20 April 2018, is Ripple. More precisely, Ripple
is the name of the payment settling system and a unit of the VC is called an "XRP". Ripple is very different
from Bitcoin in many aspects: 4
• Ripple was created and is controlled by a single private company;
• Ripple was not designed to be used by private persons for payments for goods and services. The
target groups are banks and other financial institutions that can use it as a payment settling,
currency exchange, and remittance system. The business goal of the creators of Ripple is that it will
replace SWIFT 5 as a global provider of secure financial messaging services;
• Ripple does not use Blockchain technology. A unique distributed consensus mechanism through a
network of servers is used to validate transactions;
• XRPs are not mined. 100 billion units were issued by the creators of Ripple, 55 billion of which are
deposed in a special escrow account and slowly released to the market as governed by an in-built
"smart contract". 6 Any unused XRPs are shifted back to the escrow account;
• The average transaction cost is currently approximately 10,000 times lower than in the case of
Bitcoin, the limit of transactions per second is 150 times higher, and the transaction time is just
about 3-4 seconds; and
• Ripple uses a negligible amount of electricity as compared to Bitcoin.
Since its creation in 2012 until April 2017, the exchange rate of the XRP never exceeded US$ 0.05. In
May 2017, the XRP started to appreciate and reached US$ 0.25 on 11 December 2017. After this date,
the exchange rate of the XRP increased very sharply and reached a record-high of US$3.38 on 7 January
2018. This appreciation was very short-lived, as later the exchange rate fell dramatically. On 19 April
2018, one XRP was worth US$ 0.79.
2.3.4. Acceptance of VCs as means of payment
Only a very limited number of merchants accept bitcoins as means of payment. Examples of major
merchants that accept bitcoins are: Microsoft, Overstock—an online shop with furniture and home
appliances, Expedia—an online travel booking agency, Newegg—an online shop with electronics,
Shopify—an e-commerce platform, Dish Network—a satellite television and Internet service provider,
Roadway—a moving company, Reeds Jewellers, and CheapAir—a travel company (Moreau, 2018).
There exist, however, services that enable indirect payments in bitcoins on other platforms as well. For
example, companies such as eGifter 7 and Gyft 8 enable payments in bitcoins for goods and services
See ripple.com/xrp/; www.finder.com/bitcoin-vs-ripple; Seth, 2018; Marr, 2018.

bought from, among others, Amazon, Starbucks, Walmart, and Uber. From a technical point of view,
the customer buys gift cards for bitcoins, which are later used to pay for goods and services. In other
words, the aforementioned companies act as intermediaries between the clients and a particular
merchant. Since the merchant receives payments for the gift cards in a sovereign currency (usually
US$), one cannot consider these transactions as payments in VCs.
2.4. Potential economic advantages and disadvantages of VCs
(opportunities and risks)
Enthusiasts of VCs refer to a number of their potential benefits. Most important of them are: low
transaction costs (especially across borders), speed of transactions, and increased anonymity (no need
for disclosure of sensitive data while making transactions). The EBA (2014) argues that these benefits
may be substantial outside the European Union (EU) where payment infrastructure is less developed
or less trustworthy, but EU legislation makes them less significant inside the Union. Moreover, some of
these alleged benefits incur associated risks that are discussed below.
As mentioned earlier, VC transactions are conducted directly between the payer and the recipient and
are validated by the community of miners, who compete for transactions in exchange for fees and
newly minted units of VC. The cost of fees is hard to estimate due to a lack of reliable data, but anecdotal
evidence suggests that they tend to be less than 1% of the transaction amount, compared to 2-4% for
traditional online payment systems (EBA, 2014, p. 16). Moreover, the use of VCs enables the involved
parties to avoid costly conversions of currencies, which is why transactions in VCs are particularly
popular in the case of cross-border trade. 9
The EBA argues, however, that the lower cost is partly associated with the lack of any regulatory
requirements that would guarantee the safety of these transactions. Moreover, in addition to fees,
miners are also compensated with newly created VC units, the supply of which is set to decrease over
time. Having that in mind, it is reasonable to assume that the fees need to increase over time in order
to compensate the miners for their investment in necessary processing power. Finally, the difference
in costs between VCs and traditional payment systems is much lower in countries that are part of the
Single Euro Payments Area (SEPA)—the EU's payment integration and simplification initiative.
Furthermore, EU regulations equalise fees for national and cross-border payments in euros,
significantly reducing the potential benefits of using VCs inside the Union.
Another alleged benefit of VCs is higher speed of transactions compared to traditional banking
transactions in sovereign currencies. For example, Bitcoin is referred to as a near-instantaneous
payment system, as it takes on average 10 minutes to process one transaction (Badev and Chen, 2014,
p. 6-7). Another advantage of VCs is that payments are validated on 24/7 basis, whereas traditional
payment systems usually have no more than several clearing sessions per day and do not function
during holidays and weekends. What must be mentioned here, however, is that several countries have
already established instantaneous payment services for sovereign currencies and they process
transactions even faster than Bitcoin. Badev and Chen (2014, pp. 6-7) argue that the VC transaction
process is fairly complex, and some computer scientists have questioned its suitability for fast
payments.
Transactions in VCs also offer increased anonymity resulting in the higher security of personal data and
limited interference by public authorities. An advantage of VCs is that payments do not require the
Currency conversions are particularly costly when currencies used by the payer and the payee are not directly convertible
and the local currency of the payer needs to first be converted to a reserve currency (e.g. US dollar or euro) and then to
the local currency of the payee.
provision of sensitive data such as name, address, credit card number, or phone number, which are
often necessary to authorise payments in conventional payment systems. This feature of VCs excludes
the possibility of potential identity theft (EBA, 2014, p. 19). On the other hand, as it was written above,
perfect anonymity would be very hard or even impossible to achieve (Goldfeder et al., 2017).
Another potential advantage of VCs is greater financial inclusion. The EBA (2014, p. 18-19) argues that
this argument does not apply to the EU, as the Payment Accounts Directive provides cheap basic bank
accounts for all citizens in the EU that, contrary to VCs, are subject to safeguarding requirements.
Moreover, one could argue that the construction of VCs is very complicated and ordinary people have
no chance to understand how they function, especially when it comes to the details regarding
cryptology and IT technology, which makes them a potential target of fraudulent activities. This stays
in sharp conflict with the alleged benefit of greater financial inclusion.
Besides potential benefits, VCs have many disadvantages and create many potential risks for users,
merchants, sovereigns, financial market regulators, and financial stability in general. The EBA (2014)
identified over 70 potential risks associated with VCs. Some of them apply exclusively to VCs, and others
apply to sovereign currencies as well, but are more profound in the case of VCs due to a lack of
prudential regulations. Below we briefly present the most important of them.
First, it can be the loss of units of the VC due to theft or fraud. VC units can be potentially stolen from
an e-wallet or an exchange due to intentional fraud, misconduct, or a cyber-attack (hacking). The best
example of this is the bankruptcy of the Tokyo-based company Mt. Cox in February 2014—one of the
biggest bitcoin exchanges at that time. It resulted in the loss of 850,000 bitcoins valued at almost US$
0.5 billion (Badev and Chen, 2014, p. 25 after Hals, 2014). The bankruptcy was the result of a
combination of misconduct, corruption, and fraud. During only a few years of its existence, the
company was the target of several successful hacking attacks, governmental investigations, and a
massive run on deposits. 10 There are dozens of other cases of fraud and misconduct and they seem to
be a lot more common in the VC industry than in the traditional financial services sector, mainly due to
the lack of proper prudential regulations and supervision.
VCs can be also subject to significant and unexpected exchange rate fluctuations. Although this is not
a unique characteristic of VCs and there are many historical episodes of the extreme volatility of the
exchange rates of sovereign currencies, the intensity (probability and magnitude) of this risk seems to
be more profound in the case of VCs, especially when compared to major sovereign currencies.
Exchange rate fluctuations could (but do not have to) be the result of involvement in a Ponzi scheme
or the build-up of a price bubble. An excellent example is the behaviour of the bitcoin exchange rate
to the US dollar, which fell from US$ 19,435 on 17 December 2017 to US$ 6,858 on 5 February 2018—
that is, it suffered from a depreciation of 64.7% over a period of less than two months.
As was already mentioned above, enthusiasts of VCs say that their major advantage is increased
anonymity. Even if absolute anonymity is not possible, VCs seem to help hide the identity of the private
and legal persons making transactions. This feature of VCs may be exploited by those involved in illegal
and criminal activities such as terrorism, drug dealing, illegal weapons trade, tax avoidance, and others.
Hypothetically, VCs could also help entire jurisdictions to circumvent financial sanctions and therefore
undermine the effectiveness of foreign policy. Foley et al. (2018) estimated that approximately one-
quarter of bitcoin users and one-half of bitcoin transactions are associated with illegal activities.
www.digitaltrends.com/computing/worst-bitcoin-scams/.
There are also other disadvantages of VCs that are quite extraordinary in their nature. First, some VC
payment systems consume enormous amounts of electricity. Even though computers in traditional
banks also use electricity, the amounts are not even remotely comparable.
According to Digiconomist, 11 on 7 May 2018 Bitcoin's estimated annual electricity consumption was
65.26 TWh, which is the same as that of the Czech Republic—an entire country with a population of
over 10.5 million people. When interpreting this number, one should bear in mind that the Bitcoin
payment system processes a fraction of the payments processed by traditional payment systems in the
Czech Republic alone. This raises serious environmental concerns, especially in the context of climate
change, and stays in sharp contrast with the alleged benefits of low transaction costs. Another
consequence of the development of VCs is the increase of prices and shortages of some computer
components, especially graphic cards, which are used to "dig" VCs (Gilbert, 2018).
2.5. Evolution of regulatory approach to VCs in major financial
VCs are a relatively new invention and have only recently begun to attract the attention of financial
regulators. Individual countries have different attitudes towards VCs. For example, China explicitly or
implicitly bans them while others, like Switzerland, are trying to attract VC scheme investors and
operators. Some others (e.g. Venezuela) even plan to issue their own national VCs. 12 In most countries,
especially in major jurisdictions, authorities have adopted the "wait and see" attitude, while closely
monitoring developments in VC markets. Several financial authorities (for example, in Germany,13
Poland, 14 the UK, 15 the US, 16 Singapore, 17 and the EBA 18) have issued informal warnings to the general
public, advising of the dangers of involvement in VCs.
Many representatives of monetary and financial authorities and international financial organisations
emphasise the need for the supervision and regulation of VCs. For example, Christine Lagarde, the
Managing Director of the IMF, highlighted VCs' potential as a vehicle for money laundering and the
financing of terrorism and called for "…policies that ensure financial integrity and protect consumers in
the crypto world just as we have for the traditional financial sector" (Lagarde, 2018). During the G20
meeting in March 2018 in Argentina, ministers of finance and governors of central banks agreed to
keep a watchful eye on cryptocurrencies. On the one hand, France and Germany proposed banning
deposits and loans in VCs as well as the marketing of investments based on them to the general public
(Canepa, 2018). On the other hand, Mark Carney, the Chair of the Financial Stability Board (FSB) and the
governor of the Bank of England, wrote in a letter to the G20 that "…FSB's initial assessment is that
crypto-assets do not pose risks to global financial stability at this time" due to their limited use. 19
Public authorities seem to be the most concise and decisive when it comes to tax-related issues. In
many countries, VCs are recognised as some form of financial asset or property by the tax authorities.
Consequently, tax authorities demand payment of capital gains tax on profits made on the trading of

Which would no longer have a character of private money but rather a digital version of sovereign currencies.

VCs. Such decisions were made, for example, in Australia, Germany, Israel, Norway, Poland, Singapore,
Sweden, and the US (McKenna, 2017).
Some countries introduce measures aimed to deal with the problem of increased anonymity and
related money-laundering issues. For example, on 7 December 2017, the Australian Parliament passed
amendments to the Anti-Money Laundering and Counter-Terrorism Financing Act of 2006 (McKenna,
2017). In many other countries, authorities are currently working on similar laws and one should expect
the introduction of such regulations in those countries in the foreseeable future.
Some countries are considering the issuance of their own VCs based on Blockchain technology.
Venezuela was the first country in the world that issued a sovereign virtual currency—the "petro",
which was widely interpreted as an attempt to circumvent the economic sanctions imposed by the US
(Fanusie and Frai, 2018). In response to the plans of the Venezuelan government to issue the petro, the
President of the United States, Donald J. Trump, issued an executive order banning any transactions
related to any VC issued by or on the behalf of Venezuelan government. 20
As we can see, attitudes towards VCs vary significantly from country to country and there is no clear
trend in regulations. Below we summarise the regulatory approaches of three major jurisdictions (the
US, Switzerland, and China) as of April 2018.
2.5.1. The United States
The Financial Crimes Enforcement Network of the US Department of the Treasury (FinCEN) does not
recognise VCs as a "real currency" (a legal tender), but recognises the administrators and exchangers
of VCs that are convertible into sovereign currencies as "money services businesses" (MSBs), which
means that they are subject to FinCEN's registration, reporting, and record keeping regulations for
MSBs (FinCEN, 2013).
The US Securities and Exchange Commission (SEC) issued a public statement 21 saying that VCs meet
the definition of securities as specified in federal securities laws and therefore platforms that offer
trading of such "digital assets" must register with the SEC as a national securities exchange or be
exempt from registration.
The Internal Revenue Service (IRS) issued a notice stating that for federal tax purposes VCs are treated
as property and general tax principles applicable to property transactions apply to transactions using
VCs (IRS, 2014). The notice outlines the rules applying to transactions using VCs with respect to federal
taxes. For example, "mining" VCs is considered to be self-employment and income from "mining" is
subject to self-employment tax.
The federal authorities are working on stricter laws regarding potential money laundering and tax
evasion issues. Steven Mnuchin, the US Treasury Secretary, said that he will work with the G20 to
prevent VCs "from becoming the digital equivalent of an anonymous Swiss bank account" (Mohsin, 2018).
2.5.2. Switzerland
Switzerland is considered to be one of the countries with the friendliest attitude when it comes to VCs.
As a result, according to a PwC Report, Switzerland has emerged as a hub for several successful Initial
Coin Offerings (ICOs) (Diemers, 2017). The Swiss Financial Market Supervisory Authority (FINMA) even
www.whitehouse.gov/briefings-statements/presidential-message-congress-united-states-2/.
www.sec.gov/news/public-statement/enforcement-tm-statement-potentially-unlawful-online-platforms-trading.
issued guidelines for ICOs. 22 Companies issuing VCs are required to obtain a license from FINMA, which
recently closed down a company issuing a "fake cryptocurrency E-Coin" for not having such a license. 23
2.5.3. The People's Republic of China
Chinese authorities have taken an entirely opposite attitude towards VCs. Seven government agencies,
including the People's Bank of China, the China Securities Regulatory Commission, the China Banking
Regulatory Commission, and the China Insurance Regulatory Commission issued a joint statement
where they essentially banned VCs. 24 The statement declares that offering tokens such as bitcoins or
ethers is "…an illegal public financing without approval". According to (Nelson, 2018), China appears to
have the most stringent cryptocurrency regulations among large economies. This is motivated by
authorities' desire to fight capital outflow and corruption.
2.6. Limits of effective regulations and control of VCs
One may expect that, with some time lag required to learn and comprehend the new phenomenon
and its potential economic and legal consequences, all major jurisdictions will attempt to regulate the
use of VCs, and perhaps, as in case of other financial regulations, there will be some effort to harmonise
Without the risk of guessing the unpredictable future, one cannot expect, however, that VCs will be
accepted as the official means of payment or unit of account soon. That is, paying taxes, public sector
salaries, pensions and other social benefits, or making public transfers, among others, in VCs appears a
highly unlikely scenario. The same applies to the possibility of using VCs as a unit of account in official
financial, tax, or statistical reporting.
Furthermore, financial supervisory authorities can increasingly consider VCs as risky financial assets
subject to strict precautionary prudential regulations or even legal bans which may limit their use by
licensed financial institutions, and therefore, the general public. 25 The same concerns anti-money
laundering and anti-terrorist finance legislation. Investment in VCs may become increasingly subject
to income or transaction taxes, a phenomenon already observed in several countries (see Subsection
2.5), which can limit the interest of potential investors.
However, one cannot have the illusion that even the strictest regulations and bans can entirely
eliminate the use of VCs as a means of payment in cases of private transactions (especially cross-border
ones) or as a store of value (a financial asset in which some economic agents will be interested to
invest). The cross-border harmonisation of financial and tax regulations and the cooperation of
financial regulatory authorities is never perfect, which will leave room for cross-border arbitrage.
Furthermore, as history teaches us, financial regulations always lag behind financial innovations
(Dabrowski, 2017), while VCs are a new invention with great potential for further technological
development. Therefore, financial supervisory or monetary authorities will not be able to regulate in
advance all new potential variants of VCs which may appear.

We abstract here from the question: which VCs can be used for various types of financial transactions for technological
reasons (see Subsection 2.2)?
For all of the above-mentioned reasons, one must be prepared that VCs will remain a stable component
of the global monetary and financial architecture for several years to come.
CAN VIRTUAL CURRENCIES BREAK CENTRAL BANKS'
MONOPOLIES ON MONEY ISSUANCE?
In this section, we summarise the historical experience with private (decentralised) money and try to
explain why it failed in competition against sovereign currencies (Subsection 3.1). Next, we discuss the
role of legal instruments in the hands of governments and central banks to support demand for
sovereign currencies (Subsection 3.2), and the role of network externalities in shaping global demand
for transaction currencies (Subsection 3.3). Then we turn our attention to the factors which can
undermine demand for sovereign currencies in favour of alternative money—that is, the phenomenon
of currency substitution—and ask whether VCs can potentially benefit in such circumstances
(Subsection 3.4). Finally, we present a short statistical analysis that demonstrates the rapidly increasing
demand for central bank money in major currency areas since the beginning of the global financial
crisis of 2007-2009 (Subsection 3.5).
3.1. Historical experience with private currencies and why did they fail
in competition against sovereign currencies?
To understand what kind of challenges VCs can create for central banks concerning their supposed
monopoly on money issuance and the monetary policies conducted by them, it is worth taking a brief
look back at the history of private money. As we argue in Subsection 2.1, despite their technological
novelty, VCs are a contemporary form of private money.
Strictly speaking, private money (or currency) is a liability issued by a private business entity such as a
private bank or other financial institution, non-financial corporation, non-profit private institution, or
individual, which is accepted as a means of payment by other economic agents. However, this term is
also sometimes applied to similar liabilities issued by subnational or municipal public authorities or
publicly-owned banks. In such broader interpretations, one should speak about decentralised money
rather than private money.
In modern economic history, private money was a quite popular phenomenon between the end of 18th
and the beginning of the 20th century, in particular, in various parts of the British Empire and the US,
and was associated with the era of "free banking"—that is, when banks were subject to no or relatively
light regulation and had a right to issue notes serving as a means of payment for the general public.
Usually, such private money existed in parallel with sovereign money such as coins minted by the
government or notes from government-owned banks (which, as in the case of the Bank of England,
then gradually assumed the role of central bank).
Several factors contributed to the expansion of private money in the early industrial era. First, it was
the rapid increase in the demand for money and credit which could not be met by traditional payment
means (such as gold or silver coins minted by the government). The rapid expansion of banking and
other financial services also played a role. Second, the dominant free-market economic school largely
supported free banking and private money issuance. 26 Third, in some instances, there was no political
consensus to establish a centralised monetary authority and banking regulation. This concerned, in
particular, the US after the expiration of the mandate of the Second Bank of United States as the federal
central bank in February 1836 (Frieden, 2016).
Interestingly, Adam Smith was among their advocates. The only restrictions he proposed were the ban on issuing small-
denomination notes by private banks and the obligation of immediate and unconditional redemption of issued notes on
demand—see Smith (2005, p. 269).
However, since the middle of the 19th century, the opposite tendency has started. Country after country
established central banks and gradually granted them regulatory powers over private commercial
banks, the role of a lender of last resort and the central monetary authority with dominant or even
exclusive rights to issue national currencies. The Bank Charter Act of 1844, 27 which gave the Bank of
England nearly full control over issuing banknotes in the UK, 28 and the US National Banking Act of 1863
(of similar content but without establishing the central bank, which happened only in 1913) can be
seen as important milestones in establishing contemporary sovereign monopolies on issuing national
currencies and gradually closing the era of private money and free banking.
In the 1970s, during a period of high inflation in several advanced economies, the idea of free banking
and private money was raised again by Friedrich August von Hayek (Hayek, 1990) and his followers, but
did not garner broader political attention.
To have a complete picture, one should also mention the various episodes of money surrogates, such
as scrips, promissory notes, IOUs, 29 barter transactions, and bilateral and multilateral clearing accounts,
among others, which were designed to avoid liquidity constraints. They were used under special
circumstances, such as for business activities in remote locations, bank closures in periods of financial
crisis (see Champ, 2007), wars and other conflicts, conducting trade operations in the absence of
currency convertibility, or circumventing hard budget constraints by state-owned enterprises in the
early stages of post-communist transition (Rostowski, 1994). However, money surrogates cannot be
considered as fully-fledged money and do not offer a good benchmark for comparison with VCs.
Why, historically, did private money fail in competition against sovereign currencies?
It seems that there were two major advantages of sovereign currencies: network externalities and the
potential ability to address the problems of information asymmetry and adverse selection.
Network externality means that a given currency is broadly accepted by other economic agents on a
given market and performs all functions of money (see Subsection 2.1). This allows the creation of a
sufficiently deep and liquid financial market for various instruments.
Unfortunately, this was not possible in the environment where several private currencies circulated in
parallel and competed with each other. The multiplicity of private currencies meant higher transaction
costs for all economic agents on a given territory. Even if they were denominated at the same currency
unit (for example, pound or dollar), they were traded at various discount rates depending on the
reputation and reliability of their issuers—that is, there were de facto exchange rates between them,
sometimes volatile and unpredictable ex ante.
Sovereign currencies eliminated this multiplicity (not entirely because of the use of foreign currencies
– see Subsections 3.3 and 3.4) and helped to create single domestic markets for goods and services in
individual monetary jurisdictions. This was an important network externality for all economic agents—
using the same currency as your purchasers, suppliers, creditors, debtors, and tax authorities, among
The problem of information asymmetry (i.e. the information advantage of the provider of financial
services over its clients and the inability of the latter to fully assess the quality of the purchased product,
including private currency) is inherently present in financial intermediation. This creates the potential
for taking excessive risk at the cost of clients and even the risk of the intentional abuse of rules or fraud.
See https://www.legislation.gov.uk/ukpga/1844/32/pdfs/ukpga_18440032_en.pdf.
Even if, technically, a few commercial banks in Scotland and Northern Ireland continue to issue their own banknotes
today, they remain under the full control of the Bank of England in this respect.
An acronym for "I owe you", a sort of debt obligation paper.
Furthermore, opposite to the arguments of Smith (2005) and Hayek (1990), free banking competition
does not always lead to the selection of the best products (in this case, private money) and the best
providers. Hence, the necessity to address the problem of information asymmetry and adverse
selection 30 serves as the main argument in favour of the government regulation of financial services.
The same argument has been often used in favour of the government monopoly on issuing money,
even if history offers a large number of abuses of such monopolies, mainly for fiscal reasons (see
Reinhart and Rogoff, 2009). Eventually, the importance of having stable and trusted money for the
proper functioning of the market economy forced most countries to adopt the gold standard in the
second half of the 19th century, which largely eliminated the discretionary monetary power of
governments. After several modifications of the gold standard in the first half of the 20th century and
its definite demise in the early 1970s (see Eichengreen, 1998) and short period of higher inflation, the
role of the stabilisation mechanism was taken by central bank independence and publicly declared
monetary policy rules such as inflation targeting.
Looking at the technological characteristics of VCs (Subsection 2.2), at least some of them (like Bitcoin)
offer the chance to eliminate at least part of the above-mentioned disadvantages of private money.
The transparency of their functioning and the predetermined algorithm of their creation reduce
information asymmetry and the risk of over-issuance. However, their exclusively digital form, the quite
complicated and labour-intensive mechanism of their creation, and the lack of political willingness to
accept them as official legal tender in any jurisdiction (at least in the near future) will limit their
circulation and use and make them unlikely competitors to sovereign money.
3.2. Legal instruments in the hands of governments and central banks to
support demand for sovereign currencies
In most countries, demand for sovereign currencies issued by central banks or governments is
supported through various kinds of legal regulations, beginning with the constitution and going
through central bank legislation, banking and financial sector regulation, civil code, labour and tax
legislation, foreign exchange regulations, and accounting and statistical standards, among others.
Usually, these regulations require conducting and reporting domestic transactions in the respective
sovereign currencies. The same concerns paying taxes, wages and salaries, social benefits, and
government subsidies. The regulations also give the central bank the exclusive right to issue money. 31
However, all of these legal instruments have limits of their enforcement. First, most economies are
open to an external world in terms of trade in goods and services, financial transactions, investment,
and movement of people, to name a few. Transactions with non-residents often require using other
currencies than the domestic currency, unless it is one of the major global currencies accepted
worldwide (see Subsection 3.3). Second, in most countries, residents have freedom of choice, de jure or
de facto, of the currency in which they make their savings or financial investments—that is, to use
money in its function as a store of value. Such freedom is the norm in all economies that accept capital
account convertibility. It is also accepted or tolerated in countries that continue capital account
restrictions. Furthermore, the history of communist or other totalitarian regimes demonstrates that
even the strongest bans on using foreign currency (backed by criminal penalties) remained
unenforceable. Third, if residents consider domestic currency unstable or if using it is inconvenient for
A large body of economic literature on asymmetric information and adverse selection goes back to the seminal papers
of Akerlof (1970) and Stiglitz and Weiss (1981).
Article 128.1 of the Treaty on the Functioning of the European Union also gives the ECB this exclusive right in respect to
the euro area.
any practical reason, they may prefer using foreign currency for transaction purposes as well (see
Subsection 3.4). Usually, this applies to larger transactions such as selling or purchasing real estate, cars,
or other durable goods of a larger value or making private loans. Legislation that requires making such
transactions in the sovereign domestic currency can usually be easily circumvented.
In summary, legislation that requires using the sovereign domestic currency can help boost demand
for that currency and discourage the use of other currencies, but only as far as it does not contradict
the interests of economic agents. If the economic agents consider a given sovereign currency unstable
or if using it remains inconvenient for other reasons (for example, for transactions with non-residents
or for portfolio diversification), they will circumvent such legislation.
The above conclusions apply also to VCs. While the legal instruments discussed in this subsection and
the various regulatory measures analysed in Subsection 2.5 do not help in the broader use of VCs and,
in fact, diminish their chances of competition with sovereign currencies, they are unable to eliminate
them completely from economic life (see Subsection 2.6).
3.3. Private sector preferences—the role of network externalities
What about the potential role of VCs in international transactions that are not necessarily subject to the
regulations of any particular country? The era of the gold standard and the Bretton Woods system is
gone; in reality, we live in a world of free currency competition with largely floating exchange rates.
The very fact that the US dollar and—to a lesser degree—euro have dominated trade and financial
transactions and have become the major reserve currencies does not make politicians in many
countries happy. Hence, political initiatives to invent a politically "neutral" reserve currency other than
the US dollar or euro based, for example, on the IMF's Special Drawing Rights SDR. 32 However, these
initiatives have had no chances to materialise thus far because there has not been market demand for
such a currency (see below).
Obviously, due to their private nature and technological characteristics, VCs (at least in their current
form and in the foreseeable future) do not have the chance to become official reserve currencies.
However, is it possible that they could overtake at least part of the role played by the US dollar, euro,
and a few of the other major currencies (e.g. the Japanese yen, British pound, or Swiss franc) in
international private transactions? Unlike the above-mentioned political proposals to create a new
international currency, VCs were spontaneously created by market forces and have developed thanks
to market demand.
Again, network externalities play a dominant role here: the strong market position of major sovereign
currencies, especially the US dollar, is determined not only by their reputation and expected stability,
the size of their markets, and, sometimes, financial and foreign exchange regulation, but, in the first
instance, by the dominant preferences of other market players. This allows for reduced transaction
costs. In turn, these preferences are determined by the size and depth of a global financial market in a
given currency—that is, the availability of various kinds of financial instruments in a given currency
and, to some degree, by inertia.
This is the key reason behind the continuing dominant role of the US dollar as the international reserve
and transaction currency, both in government and in the private sector, despite its periodic fluctuations
against other currencies and the not always superior macroeconomic performance of the US economy
(Dabrowski, 2010).
For example, such a proposal was presented by China and Russia in 2010 (Dabrowski, 2010).
That is, if VCs were to challenge, at least partly, the international transaction position of the US dollar
or euro, a sufficiently large volume of transactions would have to be developed first. This looks like the
typical chicken or egg dilemma, which will unlikely be solved, at least in the near future. Most probably,
a large-scale global crisis which would undermine market confidence in all major sovereign currencies
(not just the US dollar) would be required in order for VCs to have a chance to play a more powerful
role.
3.4. The source of potential competition to sovereign currencies—the
role of currency substitution
As discussed in Subsection 3.2, the legal monopoly for sovereign currencies in individual countries is
not and cannot be complete due to the role of international transactions, the freedom of choice of
economic agents in respect to the currency of their savings or financial investments, and the
unenforceability of rules that are too restrictive. That is, financial globalisation and the increasing
sophistication of financial services facilitate an increasing competition between individual currencies—
perhaps in the Hayekian spirit—even in macroeconomically and financially stable economies.
If a given country suffers from macroeconomic or political instability and uncertainty (or both), there
are strong incentives to run away from its sovereign currency—this is the phenomenon known as
currency substitution. Again, the question arises as to whether VCs can benefit from such situations—
that is, will the person fleeing the troubled sovereign currency be ready to choose a VC instead?
The increasing interest in mining bitcoin in Venezuela, a country that is suffering from hyperinflation
(The Economist, 2018), suggests a positive answer to this question. However, it does not seem to be
comparable with the flight to the US dollar, especially in the form of cash—the most popular variant of
currency substitution. Unfortunately, we do not have statistics illustrating the size of the additional
demand for bitcoin in Venezuela, as we do not have data on the circulation of the US dollar in this
3.5. Increasing demand for central bank money in major currency areas
Despite all speculation about perspectives to crowd out central bank money, especially cash, by digital
money—both sovereign currencies in an electronic form and private VCs (see Dabrowski, 2017 for an
overview of this debate)—the available statistics do not confirm such a trend. On the contrary, since
the beginning of the global financial crisis in 2008, one may observe a rapidly increasing share of the
central bank's money (called reserve money, monetary base, base money, or high-powered money) in
broad money in the major currency areas (Figure 5) as result of crisis-related financial
disintermediation, tighter post-crisis financial regulation, currency substitution in favour of major
currencies (mostly in the form of cash), low inflation, and low interest rates, among others (Dabrowski,
2018). Other analyses (see, for example, Jobst and Stix, 2017; Gros, 2017) also confirm an increasing
demand for cash issued by major central banks.
Even if this trend is going to be reversed at some point as result of the expected monetary policy
"normalisation" and the recovery of financial intermediation, central banks—especially in major
currency areas—will not face the risk of a diminishing demand for their money and, hence, losing
control over monetary policy.

SUMMARY AND CONCLUSIONS
VCs are a contemporary form of private money, which was largely absent from economic life in the 20th
century. Thanks to employing Blockchain technology (which may also be used in the financial industry
for other purposes), the transaction networks of VCs are relatively safe, transparent, and fast. Unlike
their 18th and 19th century paper predecessors, VCs are used globally, disregarding national borders.
The economists who attempt to dismiss the justifications for and importance of VCs, considering them
as the inventions of "quacks and cranks" (Skidelsky, 2018), a new incarnation of monetary utopia or
mania (Shiller, 2018), fraud, 33 or simply as a convenient instrument for money laundering, are mistaken.
VCs respond to real market demand and, most likely, will remain with us for a while.
Policy makers and regulators should not ignore VCs, nor should they attempt to ban them. Both
extreme approaches are incorrect. VCs should be treated by regulators as any other financial
instrument, proportionally to their market importance, complexity, and associated risks. Given their
global, trans-border character, it is recommended to harmonise such regulations across jurisdictions.
Investment in VCs should be taxed similarly to investment in other financial assets.
Analysing the impact of VCs on monetary policy, the main question is whether they have the potential
to compete with the sovereign currencies issued by central banks. Enthusiasts of private money and
free banking are excited about such a prospect and hope to see it materialise (see, for example, Lietaer
and Dunne, 2013; Milling, 2012).
However, the answer seems most likely "no", despite the relative market success of Bitcoin and the
chances for similar successes with its followers. After almost a decade since its creation, and
notwithstanding its acceptance by some digital platforms and strong market value, its role remains
marginal. In April 2018, the total market capitalisation of all VCs was below US$ 300 billion (Subsection
2.3, Table 1), while broad money (M3) in the US approached US$ 14 trillion at the end of 2017.34
Differences in the number of transactions is even more strikingly in favour of sovereign currencies.
That is, the monetary dominance of major central banks and major currencies seems to remain
unchallenged in the near future. However, the prospects may look different in smaller monetary
jurisdictions, especially in countries where the sovereign currency remains inconvertible or does not
enjoy the trust of economic agents due to its poor record of stability or due to political and economic
uncertainty. Such countries already struggle with the phenomenon of currency substitution in the form
of spontaneous dollarisation or euroisation. VCs may offer another avenue for currency substitution, as
observed recently in Venezuela.
One cannot rule out that future progress in the area of information technologies can bring even more
transparent, safe, and easier to use variants of VCs. This might increase the chances for VCs to effectively
compete with sovereign currencies, including the major ones.

1) What are, in opinion of the ECB, main risks for financial stability connected to virtual currencies?
2) What actions were taken already by the ECB in order to mitigate them?
3) What actions is ECB planning to take in the future in order to mitigate these risks?
Virtual currencies are a contemporary form of private money. Thanks to their technological
properties, their global transaction networks are relatively safe, transparent, and fast. This gives
them good prospects for further development. However, they remain unlikely to challenge the
dominant position of sovereign currencies and central banks, especially those in major currency
areas. As with other innovations, virtual currencies pose a challenge to financial regulators, in
particular because of their anonymity and trans-border character.

Born in Baltimore, Maryland William Weintraub has become one of Israel's best known painters of Israeli people. Mr. Weintraub is a graduate of the Maryland Institute of Art. He studied under renound teacher Jacques Maroger. As a volunteer in the US Merchant Marines in 1944, Weintraub found his subjects in his trips to Europe and the Mediterranean. After a brief internment in Cyprus, Weintraub arrived in Palestine to participate in the War of Liberation. In 1947, he joined the crew of the old SS Hatikva which was being used by the Palestinian underground to transport Jewish refugees from Europe. On his first voyage, the slow ship was intercepted by British destroyers and all those aboard were interned in Cyprus. Sketches he made there of life in the detention camp were confiscated. Following a stint in the Israeli Merchant Navy, Weintraub settled in Tel Aviv in 1955 to give all his time to painting. He has held successful one-man shows and participated in group exhibits in Israel and abroad.

'Separated' is the witty comedy that follows a group of four childhood friends as they begin a new journey of singlehood and freedom together. Now in their early forties and separated from their wives, they are finally unleashed and on the loose! But as they try to relight the spark of their youth and let their inner-children spring to life, they discover that their independence is not all it's cracked up to be… Whether about getting back in shape or working on their flirting skills, each stand-alone episode follows the friends' search for happiness and the creative, ridiculous and absurd ways that they go about it.
Aired on Israel's Channel 2, Separated increased the slot's average share while also beating the ratings of competing shows in the genre.
They may be older but they're definitely not wiser!

Posted By : Andrea Faulk/
Under : DAVEY SUICIDE, Press Releases
DT: NOVEMBER 5, 2019
FM: KELLY WALSH, SRO PR
TO JOIN STATIC-X AND WEDNESDAY 13

Industrial goth/rock quartet DAVEY SUICIDE will treat audiences across the West Coast to the first glimpse of new material from their upcoming album ROCK AIN'T DEAD-out January 24, 2020 via Out Of Line Music/InGrooves-as they join industrial acts Static-X and Wednesday 13 on a jaunt across the West Coast this winter. Kicking off Tuesday, December 10 in Salt Lake City,UT, the tour marks the 20th anniversary of Static-X's debut album Wisconsin Death Trip featuring the late Wayne Static and includes two sold-out shows in Portland, OR on December 13 and Seattle, WA on December 14. Dates are listed below.
"Static-X and Wednesday 13 brought us out on our first two tours in 2012," shares
DAVEY SUICIDE. "Now, here we are seven years later, paying homage to the life of Wayne Static for eight amazing nights. We're thrilled to be a part of this tour and can't wait to debut new songs off our upcoming album."
ROCK AINT DEAD, the fourth album from DAVEY SUICIDE, was mixed and produced by Charles Kallaghan Massabo (Falling In Reverse) at Kallaghan Studios in Los Angeles while being mastered by Shawn McGhee (Five Finger Death Punch, Papa Roach, Hellyeah) at Artistry Studios in Las Vegas. The album highlights SUICIDE's signature blend of arena rock, sleaze and industrial music with a theatrical edge.
Available for pre-order now at www.daveysuicidemerch.com, ROCK AINT DEAD features several guest appearances including Gustav Wood (Young Guns), Hyro The Hero and Lexus Amanda (Blacklisted Me) and Telle Smith (The Word Alive), the latter of which is featured on the album's debut single "Medicate Me." Watch the music video, starring actress Scout Taylor-Compton (Rob Zombie's Halloween I & II, The Runaways) and directed by Vicente Cordero (3 Teeth, Cradle of Filth, Tom Kiefer), here: https://www.youtube.com/watch?v=NRMJchZp3A4.
SUICIDE recently premiered the futuristic, sci-fi music video for the album's second single, title track "Rock Aint Dead" via Alternative Press, here: https://www.youtube.com/watch?v=ySsdnWpC9Zg (note: Skip to the music at the 6:13 mark)
Previously lauded as Kerrang Magazine's "Top 50 Rockstars in the World," Alternative Press' "100 Bands You Need to Know," and Revolver Magazine's "Ones to Watch," DAVEY SUICIDE "incorporates the anarchistic bite of vintage Marilyn Manson with the stadium feel of Bring Me The Horizon and the anthemic melodies of Korn and In This Moment."(Jammerzine)

The holidays offer a dizzying string of opportunities to eat and drink too much, stay out too late, and generally over-do it in ways that can you leave you looking and feeling less than stellar. We asked Keri Glassman, a nutritionist in New York City, how to recover between bouts of overindulgence.
__Beat bloat.__Drink a cup of herbal tea each morning and night, and guzzle water throughout the day to minimize bloat, says Glassman. "Dandelion root tea is especially good at flushing you out," she says. And be aware of your salt intake: "When you're having decadent meals, stay away from sodium for the rest of the day," she says. It's also a good idea to steer clear of carbonated beverages—even diet ones. "The chemicals make you retain fluid, and can increase your craving for sweets," says Glassman.
Cut out one vice. If you pass on candy, for example, you could save at least 300 calories a day; white bread, up to 1,000 calories a day; red meat, 200 calories a day; and cheese, several hundred calories in one sitting.
Recover wisely. Get back on the right track as soon as the New Year starts. "Eat healthy for a solid week right after the holidays, and then keep it going for as long as you can after that" says Glassman. Some juice cleanses are a good weight loss tool—but not the ones that leave you famished. "Just make sure they have adequate calories, like the Blue Print Cleanse," she adds. The safest bet, though, is to stick with small portions of whole grains, lean protein, raw vegetables, and healthy fats like those in avocado and almonds. One of Glassman's favorite meals is scrambled eggs with one yolk and dried oregano, spinach, or basil for flavor.
