I have done trading in exchanges like binance, kucoin, mercatox, etc...
Can you post your favourite crypto exchanges you are trading without any problem?
My favorite exchange wouldn't make it any safer or any convenient for you to trade on, it'll simply be my own discretion or my own words probably based on my experiences
Basically it's pointless posting this in here when you can get your answer by simply googling it up, and getting much more reliable answers with articles and plethora of reasons backing it up
