To link your PayPal account with a cryptocurrency exchange, first, ensure that the cryptocurrency exchange you are using supports PayPal as a payment method. Once confirmed, log in to your cryptocurrency exchange account and navigate to the “Payment Methods” or “Wallet” section. Look for the option to add a new payment method and select PayPal from the list. You will then be prompted to enter your PayPal account details and authorize the connection between your PayPal account and the cryptocurrency exchange.
