Hallo Capoeira,

Could you tell me if FXopend and FXchoice offer ANONIMOUS FOREX BITCOIN ACCOUNT like 1Broker or Simplefx?

No, they do not. You can't do anything there without IDing yourself. 1Broker and Simplefx are the best options for this

Have you Try Evolve Market?

I will have a look at this, thanks

what about binary tradings with btc, is there any site out there that we can use ?

I don't consider binaries trading, afaik SimpleFx has them, though for example
