In the past 1 week, I did not do any transactions on the ETH network because its gas fees were too high. I think the reason the gas of ETH goes up is because investors are interested in Defi projects and has made the ETH network congested as it is now.
It looks like most of the transactions that were increasing the gwei in the network came from the uniswap and I have expected the launch of a lot of new defi projects have been making the ethereum network being so crowded
