Well if they following regulation am sure everything will be fine but then again if not then only time will tell if they are doing things within the legal limits or they are actually taking illegal action and not following rules and regulations but many use btc-e if governments where to act and stop them then it would be another big exchange to leave and no doubt the down fall for BTC prices. But if that is not the case then what about coinbase that is in San Francisco, California surly with the rules and regulations in the US will get pulled apart but does coinbase follow rules regulation and regulated. Am sure I seen a new exchange popup that was meant to be supported by the government but so far as yet to see results.
I would not like to see that though, the price is already dangerously too low, and we dont want bitcoin to die just now as many many retailers and people start to acknowledge it. So please let these exchanges continue atleast 3-4 more years until they diversify themselves so that bitcoin to have enough time to spread between people!
