Hi, I'm totally new in crypto. I just purchased $60 USDT (Erc-20) in my Coinbase wallet. I wish to trade or swap it. But, when I am trying to do it that's the time it shows that "I don't have enough Ethereum for Gas fee". Please help me and let me know is there any option to do it without Gas fee?
Didn't tried yet sending an ETH from Coinbase but there should be a preview of the gas estimates you will be used on the transaction. I say that because when sending BTC from Coinbase, there's a preview of the fee on the transaction before sending it. The same case might be on sending ETH.
No choice but you need to add ETH to your Coinbase wallet. Make it around $50-$100 to cover the fees. With the Berlin upgrade, I saw at least a low gas fees now compare before. Or you can trade it to their own trading platform, Coinbase Pro so you don't need to send it to other trading exchange.
Next time, buy ETH on the platform where you will trade it if possible to avoid any further transfers.
