Why is the fee for sending USDT higher than the fee for sending ETH?
While sending the USDT you should add the ETH wallet. The information about it can be found here. However, the fee for sending the USDT is higher than for sending the ETH. This is a general problem for every wallet.
That is why please note that for sending the USDT you should have a big amount of the ETH. Otherwise, the sending will not proceed. But the final commission will be lower than the required amount in your ETH wallet. The rest of it stays in your wallet.
We suggest you to check the amount of ETH you have in your wallet before sending the USDT.
