If you like rewards and great promotions try KuCoin, they have a huge campaign that last for some time already. I use all exchanges on this list and, maybe more that aren't on the list at all. All active crypto people are registered on many places, it's going like that, you start with one, then other have better pair so you register on that place too, new coin is accepted on third exchange, you register there, and after few years you have accounts in all major and few little exchanges. It's come with the time and with a need, I use them all from time to time, but I don't trust any exchange, I keep my money in a safe place, just some parts for trading are in exchange wallet.
