Crypto-funds now total 124, with over 90 opening this year
The total number of crypto-funds has reached 124, with 90 launching in 2017 alone, according to data from research firm Autonomous Next. It revealed the sector's total assets under management were $2.3bn, a fraction of the $3.15tn held by hedge funds, but digital currency funds remain a growth market. Despite continued scepticism from Wall Street, the surge in bitcoin's price has attracted veteran money managers, including Michael Novogratz, who is raising $500m through his new firm, Galaxy Investment Partners, to launch the biggest digital assets fund of its kind.

More than 90 funds focused on digital assets like bitcoin have launched this year, bringing the total number of such "crypto-funds" to 124, according to financial research firm Autonomous Next.

Data shared exclusively with CNBC Friday showed that the largest share of the funds, 37 percent, used venture capitalist-type strategies and had about $1.1 billion in assets under management. Funds focused on trading digital assets came second at 32 percent, with about $700 million in assets under management.

Funds specifically using machine learning, data science or statistical arbitrage on digital currencies came in third at 10 percent and $100 million in assets under management, the data showed.

Total assets under management by crypto-funds now stands at $2.3 billion, according to Autonomous Next's estimates.

This year's surge in the price of bitcoin and another digital currency, ethereum , have drawn attention to the cryptocurrencies and the potential of their blockchain technology. Proponents say blockchain could transform the world as much as the internet did, and several major banks are researching or developing blockchain projects.

Digital currency enthusiasts also attribute much of the latest surge in bitcoin to record highs above $6,100 to increased interest from institutional investors. While several leading Wall Street banking executives remain skeptical about bitcoin, more seasoned money managers are moving into digital assets management.

Notably, former Fortress hedge fund manager Michael Novogratz is launching a $500 million digital assets fund through his new firm, Galaxy Investment Partners. The fund is expected to be the largest of its kind.
