The minimum amount for topping up your account with USDT or USDC is $1. However, due to network fees and transaction charges, it is advisable to top up with a higher amount to ensure that these fees do not outweigh the benefit of the top-up.

使用 USDT 或 USDC 為您的帳戶充值的最低金額為 1 美元。 然而，由於網路費用和交易手續費，建議您充值較高的金額，以確保這些費用不會超過充值的效益。
