I am one of those who have HodL Ethereum since the price is 600 USD and I will continue to hold Ethereum forever.
It is appropriate and very feasible for Ethereum coins to be able to rise again like other coins because I see Ethereum has a lot of fans.
Just look at so many Dapps that are already connected to Ethereum and Ethereum is very open to the latest applications that are able to work with ERC20.
When did you buy it though? 2020-2021? Anyhow, yeah, it's good to hope Ethereum, obviously is is a prime mover in the altcoin market and so far there are attempt to dethrone it, but it's not going to happen because is has the consensus support of the community already. And then the devs are very much active as the other cryptos out there. Roadmaps and iterations to solve it's problem like high gas fees (?). So I would agree that it is a good hold, but not sure what you mean by forever, sometimes to need to make profit right?
