if you ask about "what exchange are you going to use next?" I think, I want to use trusted exchanges, which are numbers 1, 2, 3, 4, 5. Of all the rows I think that is an exchange that can be trusted. including binance, okex, huobi, indodax and others. My experience in the crypto world, as long as I keep assets in exchange, I am very grateful that I have never experienced loss of assets or been stolen by someone else. so think first before you do something.
