You're quite right I think, high leverage always means high risks despite the increased chance of winning more money. Moreover incase it's used by novices it also can blow their accounts up I guess. Speaking about risk management, I'd recommend to open a position with no more than 1-2% of the total account, of course first deposit will fly away mainly because it's like a training money, you know. And there is no need in demo account because demo doesn't make feel those emotions as real account will. I'm convinced that leverage isn't quite good for beginners and they'd better concentrate on learning and practicing, it will bring them more profit.
