What is a one-sentence summary of the following article?
Obtaining Bitcoin through an exchange is the easiest way to obtain Bitcoin. An exchange works like any other currency exchange: You simply register and convert whatever your currency is into Bitcoin. There are hundreds of available exchanges, and the best exchange option depends on where you are located, but the more well known exchange services include:  Cryptaw: This is a Singapore Based wallet service which allows user to trade Singapore Dollars for Bitcoins. The company currently has only web platform which is also mobile friendly. CoinBase: This popular wallet and exchange service will also trade US dollars and euros for Bitcoins. The company has web and mobile apps for more convenient Bitcoin buying and trading. Circle: This exchange service offers users the ability to store, send, receive, and exchange Bitcoins. Currently, only US citizens are able to link their bank accounts to deposit funds. Xapo: This wallet and Bitcoin debit card provider offers deposits in fiat currency that are then converted to Bitcoin in your account. Some exchange services allow you to also trade Bitcoins. Other exchange services act as wallet services with limited buying and selling capabilities. Most exchanges and wallets will store amounts of digital or fiat currency for you, much like a regular bank account. Exchanges and wallets are a good option if you want to engage in regular trading and don’t need total anonymity. When signing up for an exchange service, you will need to provide personal information to the service to create an account. Most countries legally require any individual or financial system using a Bitcoin exchange service to meet anti-money laundering requirements. Though you are required to provide proof of your identity, exchanges and wallets do not provide the same protection that banks do. You are not protected against hackers, or given reimbursement if the exchange goes out of business. Once you set up your account via an exchange service, you will need to link it to an existing bank account and arrange to move funds between it and your new Bitcoin account. This will usually be done via a wire transfer and entails a fee.  Some exchanges allow you to make a deposit in person to their bank account. This will be done face to face, rather than through an ATM. If you are required to link to a bank account to use the exchange service, it will likely only admit banks from the country where the exchange service is based. Some exchanges allow you to transfer money to overseas accounts, but the fees will be much higher and there may be a delay changing the Bitcoins back into local currency.

Summary:
Choose an exchange service. Provide proof of your identity and contact information to the service. Buy Bitcoins with your exchange account.
