There are lot of them, but my advice to you is to choose a trading platform that is secure, your funds are safe. Second, choose exchange with high volumes not fake, there's a lot of fake volume exchange, the good side of having high volume is, every trades has actions, so you can trade actively and analyze the chart comfortably. Last is for friendly-user exchange, easy to use and very straightforward, just like Binance, they have already a mobile application which is very comfortable to use.
