I joined Poloniex a week or so before they sprung the reg compliance demand with just a couple days notice to pack your bags and leave.
At a $2000 US cap a day I was quite comfortable giving my name and Country to comply. If I ever accumulate that kind of money, and I am making gains as I learn, I'll also move it to my offline wallet. There are no guarantees when it comes to playing the alt trading game.
Beats hell out of Monopoly ;-)
