When will the Ethereum gas fee go down? Anyone knows?
It has 2 solutions:
- if people are using Ethereum less
- if Ethereum 2.0 brings Ethereum improvements
And because solution 2 will take a very long time, we have to hope for solution 1.
It's a very sad situation.

Forget about the solution and you will never see that happen.
The biggest mining pool opposes EIP 1559. that brings a very high probability for EIP 1559 will be rejected by the miners. We know that if that mining pool has the biggest hashrate in the network.
