 Which brings us to gwei.
Gwei is a denomination of the cryptocurrency ether (ETH), which is used on the Ethereum network to buy and sell goods and services. Gwei is the most commonly used unit of ether because gwei can specify Ethereum gas prices easily.

Yes you are Right.
I think you worked hard to get this information. I often used 1Am -4AM for sending transaction through Eth because at this time the number of transaction is very less so gas fee is also low. Almkst 26 GWEI - 40 GWEI.

I know gas fee, which is the fee paid to miners during the transfer of eth or eth tokens.
Gas bills will change every moment，I have a website which will check the current gas bill.
The website is：https://ethgasstation.info
This can help you save costs,I hope it will can help you.

You need to check and select gas price for your transactions on ERC20 chain. You also can cancel your transaction or replace it with higher gas price. There are days with fee is high and some few days when fee is lower.
