Trading CFD on Bitcoin and other cryptocurrencies becomes more and more popular. Problem with most of the Crypto-CFD trading platforms is the high overnight rates, which prevent people to make long term bets. However there are a lot of benefits for short term traders, like using leverage, taking both short and long positions (shorts are not possible in most exchanges) etc. I am happy to see OANDA offering Bitcoin CFD trading. You can see comparing other Bitcoin CFD Trading brokers, but for me OANDA conditions are very competitive.
