People must understand that Bitcoin isn't anymore the plaything that it was years ago. Every exchange will face difficulties if they don't properly register their activities - especially when it comes to allowing people to exchange/trade crypto versus USD. If an exchange isn't willing to go through whatever is needed to be allowed to run a platform that involves USD, it will experience what BTC-E has gone through, what Bitfinex is, or will go through, Poloniex, etc. BTC-E however is reported to be involved in the MtGox theft back in the days. I don't like the government shutting exchanges down, but in case of BTC-E, if they are really one of the master mind behind the MtGox theft, may all involved entities burn in hell.
Admittedly, earning bitcoin is a bit more difficult than ever before. Selling a BTC to convert to USD is almost down to price and difficult. No matter what, the money still holds steady against electronic money. Although electronic money has a strong exposure, it can not pass the dollar.
