Personal wallets are preferred, because they are wallets that we personally own, such as Electrum, Trust, Safepal, ImToken etc.
If we lose Bitcoin in our wallet, we can't blame anyone because it's purely our fault because we were careless in not backing up the Bitcoin phrase itself.
If we store it in an exchange wallet like Binance, then we can claim our results or the assets we own if we lose Bitcoin as long as Binance doesn't go bankrupt.
The main keys from Binance to access our assets are Email, Telephone Number, ID Card and from all of this we must maintain as much detail as possible for our Binance account.
