What's going with gas fees? After the London fork, the gas fees only went up. They raised gas limit, and the blocks are half empty, even 5% - 15% filled, but gas fees are through the roof! It's not about limited capacity right now, yet it's very expensive. What is reason for that?
And what is minimum gasused multiplier?
The London fork did not lower the gas fees but put a fixed price per block for network fee. Burn mechanism was also been established within this EIP-1559 and miners wasn't the one who dictates the tx fees anymore. This makes ETH now a deflationary asset that could potentially rose in price as time goes by. ETH 2.0 is probably the solution for high fees. Not this EIP-1559.
