This is my list:
Binance
Houbi and Hotbit.
Binance and Houbi are two exchanges with large volumes and many attractive IEO.
Hotbit is where I can trade new currencies, and sometimes those investments are quite profitable.
I sometimes use forkdelta to sell some erc20 tokens.
However, no matter how good the exchange is, you should not put all your money on it, do not put all your eggs in one basket.
Well, these are a good exchange, it's a nice example. Well for me, I would prefer Binance and Bitmex for Crypto trading because it is proven and tested that you can be able to earn big profit here and it is recommended by a lot of traders all around the world. Much better to look for a trusted sight especially right now that there's a lot of hackers and scammers already and don't leave your fund in exchange.
