There is information that the reason for the current price drop lies in the increased risk of centralization and the possible pressure of financial regulators on coins with the PoS algorithm.
So, they write that Lido Finance and Coinbase together occupy 45% of the dominance in the network of these large players, and if two more exchanges (Kraken and Binance) are added to them, then the share increases to 60%.
Fuel is added to the fire by the chairman of the US Securities and Exchange Commission (SEC), Gary Gensler, who, a few hours after the Ethereum merger, announced the possible recognition of PoS coins as securities. If the regulator is able to secure this status, it will require crypto trading participants to follow more stringent rules.
However, reasons and explanations can always be found. I think that the current ethereum price drop is temporary and in the future this coin will significantly strengthen its position, including the price.
