You get more leverage, but there is counter party risk. Reminds me too much of 'bucket shops' which are banned now in the US. I've seen too many brokers go under to trust them. There was that big broker, FXCM (iirc), that went under when a specific currency (Russia?) depegged. Imagine losing everything because of someone else's risk management

CFD providers are LITERALLY bucket shops.
