I think it will be the same as the other altcoins when the bull run comes, the ETH price will return to ATH like last year and the other altcoins will reach ATH last year. But if you only rely on hardfork I don't think that will happen, based on the news circulating in hardfork ETH, only updating the system and this is a consideration for some investors to decide to buy or just see the hardfork process just happens.
Sometimes I even wonder if Ethereum can return to ATH，I can't imagine it. I know that Ethereum had already reached $2,000 when it was at ATH but now it is even less than $150. Let me compare them, the difference between the prices is really scary.
