I don’t understand what’s happening with ethereum because the gas fee is so high , That is the issue, I need more gas to send the coins I need to sell on different trades. That is the reason I inquire as to whether there are trades like etherdelta where I can sell the coins I have without gas, simply need the private keys.
Without paying commissions, you can only sell coins on centralized exchanges. However, in order to deposit your coins to a centralized exchange, you will need to pay a commission. I remember a time when gas cost 2-5 Gwei. These were the best times for transactions on the Ethereum network.
