I think each person can become a successful trader. So, i ask about platforms which is simple to use 
Binance is the best as it provides a lot of options in addition to high liquidity with their interest in privacy and security of accounts.Do not forget that the legal restrictions "KYC/AML" are the most important indicator in the choice of platforms so check them before searching for other reasons. "Binance offer up to 2 Bitcoin without KYC."
simple to use: Does not necessarily mean it is the best.
