Binance, Gate.io.; there are also other great exchanges and your choice of the particular exchange relies on your own taste for profit. Some of the other exchanges are better for the different kind of investors( day trading ). Before even entering the exchange study and analyze the recommendation given by the other users because not everyone is happy with the former exchanges they have been using. I would even recommend you to study the exchanges I have recommended you even if I prefer them. Choosing of the exchange is your choice alone and don't let anyone impose exchange to you.
