Crypto exchanges? They’re like a broken elevator—complicated, frustrating, and you’re better off taking the stairs.
It's obvious you must've had sad experience(s) trading cryptos on exchanges to have come up with such a frightening submission, no doubt. I can't argue otherwise with you. Nonetheless, it's not so on my part. I've the opportune moment of trading on both Forex brokerage and exchanges too. My experience isn't anything close to what you described there. I've tested both waters. Are you sure the difficulty you've been experiencing isn't from certain restrictions your country has and not that it's an exchange issue?
Again, trading cryptos on forex brokerage will leave one with less options to choose from than when one's trading on the "ideal" place – on exchanges. Forex brokers only list top cryptos, and not newly listed pairs like exchanges do. I believe you must've observed that too.
