It’s not quite like steemit keys, it’s not that the user loses their keys. The thing is that upon making a purchase, the cryptocurrency you acquire is directly stored in your exchange-hosted wallet, which is custodial, this means the exchange has control of your private keys.

Binance is a really strong and dominant platform, if they keep up their good work of course they can remain top but the have really good competitors.

Thanks for reviewing ma, I really appreciate.
