This is interesting but it can not be true because there is not any regulation over this.
Anyway, there are some forex websites in where you could use your bitcoins for trading, i used to use them for forex purposes when i was earning a lot of money through them.
SimpleFX, Whaleclub.. and the list goes on.. there are a lot of sites who let you operate with your bitcoins, not only this "newbie site" that doesnt have any trust at all.
I have been trading on Simplefx for some time, they are good and they spread fee is very low, but whaleclub is the worst forex broker that i have ever used, they fees are more than 0.0001 bitcoin per transaction, and 0.0003 if you let that operation opened for more than a day, it is more than $3 just for keeping a trade opened.
but simplefx is the best one talking about forex brokers, and you have a trollbox in where you can talk to other traders.
