SoFi, the consumer finance and wealth management startup, has begun rolling out a beta version of its cryptocurrency trading service to current members with three initial assets: Bitcoin ($BTC), Litecoin ($LTC), and Ethereum ($ETH). The firm is partnering with Coinbase to complete trades and will be available in 36 states including Alabama, California, and Ohio but excluding New York. According to SoFi, users will also not be able to withdraw their cryptocurrencies to an external wallet.
