You need to buy some cryptocurrency first.
To start your own account on any crypto exchange, you need to transfer an initial amount of money into the account. It’s very common that crypto exchanges don’t accept USD or other fiat money as the domestic currency — i.e., the currency you put into the account in the first place.
So, you should buy some crypto on the cryptocurrency exchange — or in your crypto wallet app — and transfer them to the address that the crypto exchange provides you. Although, you may also find some platforms that accept USD — as well as PayPal and credit cards.
If you don’t have enough money to trade, you may borrow it from the crypto exchange. This is called margin trading. In this case, it’s important to remember that there may be a leverage factor, which could either increase your profits or your losses.
