I might be agreed because I have some issues with other exchanges on your list, but why you put all three Chinese exchanges as the top on the list? I
I never tried Huobi though, but Binance and OKEx? Come on man, they are really good, their support are responsive, and their platform and system are very stable, compared to other exchanges. Moreover, I think Binance has set a standard for other exchanges in term of UI, and Coinlisting. I know that Binance has some problem with their API and it is abused several times, but they handle it well.

I don't know how some people said that Binance demand KYC, I have been using Binance more than 1 year and never send any documents to them, and I can deposit and withdraw any coins. I think OP is just "Chinese Exchange Hater"
