Only if the Broker is an unregulated Market Maker its possible. But i would stay away from these Buket shops.
The Problem there is they can Rob you with a vareity of tricks (or just rob you normal ) and you cant do nothing because there is no regulative Authority.

Indeed, I agree to an extent. People need to be careful when dealing with unregulated brokers dealing with bitcoin collateral and CFDs. Having said that, I've had a great experience with 1Broker, and have watched my trade execution pretty closely. Haven't noticed anything fishy (yet), or heard anything fishy about them. As a rule, I don't keep too much money there. But good things so far.
