Do you mean trading crypto? Or you mean buy crypto? Exchange means both. However, if you wanna buy crypto with with other crypto then likely you may use Binance. The advantage and disadvantages of trading on Binance is you can withdraw limited amount without KYC verification which is better than some other centralized exchanges. If you buy crypto with fiat (like credit or debit card) then Binance will ask you for KYC verification. If you are beginner on trading/exchange crypto currency then you might go with Binance rather than other exchange. When you will learned then you might go with other exchange as well.
