Withdrawal Fees: If you are withdrawing funds from an exchange or a custodial wallet, there may be a withdrawal fee involved. This fee could be deducted from the amount you send, potentially leaving you with an insufficient amount to fulfill your payment.

Integrated Exchanges: You can streamline the process by making payments directly from integrated exchanges like Binance, Coinbase, Crypto.com, and Gate.io. This allows you to pay from your exchange balance instantly, without the need for a separate withdrawal.
