That is why I might not like trading this currency, just within some seconds, they price will just shift either bull or bears, just very Volatile. Yes it should be only few have to accept Bitcoin for now till Bitcoin improved in the Market. Contrary, even if Plus500 do accept Bitcoin like you said, but the problem for some people will be that Plus500 do not accept all country on there trading platform, except if the person is registering as a affiliate or associate (just to help them get more referral or Traders).
