Lately a new "Exchange 2.0" taking over. Bittrex & Polo suffer from many complains, locking accounts and many other issues.
Kucoin & Binance are quite different. they have their own token which give benefits.
Both are going very big in Asia and International.

My opinion is this: Their fees are too damn high for some coins! So, I used 50$ to by 2700 tokens, when I wanted to withdraw those to myethwallet, I had to pay them a flat fee of 800 tokens.
I mean, WHAT THE HECK? That's rip off! I had it with these exchanges!
