Ethereum is hampered by its huge fees. Coins have long been predicting a great future. Ethereum is no less promising than Bitcoin. I think today's ATH records are not the limit and ETH fans will be surprised when Ethereum actually breaks its own record.
Huge fee issue is still a problem to be solved, not die hard fans but with this huge fee issue will make a lot of fans difficult, and considering that ethereum is the number 2 crypto with a lot of users, I'm sure it will be quite difficult to get new ATH if this problem still surrounds them
