Quote from JSSPMK:
Online casinos have already been banned in the US. I have no answers regarding Vegas, I think that will stay as it is. Trading from home may be linked to gambling from home. Like it or not, it will probably change pretty dramatically.
Online casinos are banned in US because they could not collect tax on that. It is a competition to the gambling facilities built by the states.
And since we are looking at a new administrator here, my guess is that online casinos will be made legal - US citizens can gamble and invest, with US companies only
