Poloniex is not going to be a "safe haven" from regulation. Quite the contrary. They have been bought by Circle who is backed by Goldman Sachs. They are looking at going very mainstream. They will embrace regulation as it will bring in the institutional folks. Rumor has it they have been in touch with SEC who allegedly has told them that if they follow the rules going forward, they will not be held liable for securities violations by the prior owners.

Another good reason not to keep coins on exchanges. Especially centralized ones. Especially if you are avoiding the rules and regulations of the jurisdiction in which you live.

The good news is that this will most likely be the beginning of crypto going mainstream. That means (presumably) high prices.

Civilization is coming to the wild west. For good or bad.
