That sounds really strange to me to be honest. I know gas fees are high but yesterday all day I could see it max was 200 for almost instant confirmation. I still sent 150 and it was confirmed in less than 1 minute, for sure 100 would get you 2 minutes.
But you are right, checking etherscan now, it has updated a new recommended gas fee next to price. 320!
Oh my god! Unbelievable, I didn't expect and think that the gas fee of ETH can be so high like this! I'm aware that the fee is high, but it is way more than I can imagine. I know that when the trading volume is high the fee has to increase also. Even though it's kind of shocking but not too surprising. It just increases too fast! In my opinion, it will keep raising if the ETH price increases!
