In Revolut i can only buy , sell and send crypto , i dont see an exchange option. So i should withdraw my crypto and invest them in an exchange crypto app ?
Can you withdraw your crypto is what I'm asking. if you can withdraw or send your crypto to your personal wallet, then I don't see any harm in using them. It's basically like any other exchange platform.
But if they don't, then you should switch to a proper exchange instead. Sell your crypto to fiat, and use it to buy the coin you want in Coinbase for example, and then withdraw that to your personal wallet.
