Before I joined this forum I used an exchange called BINANCE.
Haven't used the exchanges that you show here, although they are also among the best exchanges, in your opinion.
What would be a good exchange mobile app to use for trading coins?
Coinbase, coinbase pro
You have a country, of course in your country you have your own local exchange, if you know it, but if you do trade globally, You can turn a little bit to trade on Binance, the exchange is covered in security and is served in a professional manner.
