In fact today the price of Ethereum dropped, maybe the market conditions dumped so that Ethereum was also dumped, maybe it has little to do with Ethereum merge. It is possible to hard fork ETHW, so that the price of Ethereum drops. Because they have to raise funds for ETHW. This is just my guess, it might be wrong. I'm not selling Ethereum, I think it's too late if I should sell it now. Because I also found rumors about the market will grow back in the near future.
