poloniex beside US too, but they aren't act like Bittrex and scam their users. at least Bittrex should wearing their users and give them time to withdraw their funds. that is if Bittrex was a lighnt exchange.
https://news.bitcoin.com/cryptocurrency-exchange-poloniex-bought-circle/Poloniex will change too.
Bittrex is preparing to cater for the big big growth phase - the wallstreet traders. For that they have to have a higher standard of compliance and it will put them under further scrutiny.
I believe that exchanges that are of vague owneship or country of residence like HITbtc, Binance and Yobit may become increasingly a target for regulators.
In order to become a mainstream accepted exchange they have to comply with a variety of existing laws and increasing regulation.
HiTbtc is based in Europe? Binance is in Malta and that place is very friendly to crypto. And Yobit is I guess in Russia? Ffs, Yobit should cease to exist. It is a shame that the Russian government is not shutting that scammy exchnage. Yobit don't deserve to be mentioned with exchanges like Binance and Hitbtc.
HITbtc UK company registration looks suspicious because it appears they never lodged any financial accounts and got deregistered for failing to file. Since then they moved to Hong Kong registration:
Hit Solution Limited
Unit 19, 7/F., One Midtown No.11 Hoi Shing Road,
Tsuen Wan, New Territories, Hong Kong
Binance has been running into a lot of legal trouble lately in Asia — in Hong Kong, China, and Japan, where it primarily operates. Binance was one of the seven cryptocurrency exchanges that received a warning letter from the Securities and Futures Commission

Zhao Changpeng lives in hotel rooms and the exchange is in an undisclosed location.
I like their platform and their service appears to be reliable. But I am concious that there may problems locating the operator if things go wrong - or if the authorities crack down on licensing.
Yobit is based somewhere in Russia and despite their bad reputation I have had some surprisingly positive experiences with them.
