Personally, am not really into day trading, am an investor kind of guy but anytime or day i decide to do some trading, i always go with Binance exchange as the exchange seems to be the one with the most volume and liquidity to power or support easy and instant buying and selling of crypto currencies.\
There are still other very good exchanges i like very much, like houbi global is a very good exchange, okex, kucoin, all this are very good centralized exchanges but binance is always better.
