Gas fees should not be the reason but bitcoin is. Did you aware if bitcoin was also dropping a bit too from its weekly position? that makes sense if another crypto other than bitcoin will get the same correction like bitcoin.
People are only seeing it based on the price without trying to analyze what the main thing that has been making ethereum gets dropped a bit.
here's the trend. Bitcoin goes down and altcoins too.
Transaction fees on Ethereum network was high in 2020 since September.
Ethereum Transaction Fees Hit Record Highs as Ether, DeFi Coins Soar. I don't think that the new record of transaction fee is the cause of price fall. If you consider the growth of Ethereum last few months, its price need to be corrected. Fee record is what you saw, not the cause.
Bitcoin is another cause in the net of causes.
