Well sp I guess time will tell but in my opinion these people don't care what they trade so long as the odds are in their favour,did you know you can trade on political outcomes in the US and I read somewhere that they are also going to trade future contracts on hollywood box office numbers.With this in mind I would agree with nadler,if you restict them they will simply pick up their bat and ball and find another market to play in.I'm not sure what would happen to gold if this happened, us retail investors can be erratic and let to our own devices anything could happen.
