Negative. If you're trying to pinch your pennies when it comes to eth gas fees, you can rely upon a good Ethereum blockchain scanner, like etherscan.io. It scans the blockchain and crunches all the data you can think of. Using etherscan.io, you can find when the average gas fee is the lowest, which is usually in the wee hours of the morning and do all your transactions then. But waking up at 2 am just to run through some crypto video game transactions feels like the first step toward addiction of some kind, so I leave that up to you.
