Nice to see other's comments here because I've been wondering the same thing. I didn't jump into Binance right away because I didn't trust the new exchange but I'm beginning to think that exchanges outside the US might actually be more secure due to the government forcing regulations. I mostly use a trading bot (Gunbot) and its next release supports Binance... when it does I'm going to transition away from Bittrex.
Recently started to use Binance and it's the only exchange that has never given me Cloudflare-errors in the past two weeks. Works like a charm every day and deposits/withdrawals are also processed faster than anywhere else. I've been using it without KYC. They got pretty much every alt you can think of as well so it's a great place to trade.
