Are you expecting altcoins to have a separate bull run? I don't think that's really going to happen because the market generally moves up and down with Bitcoin, and if Bitcoin's bull run is over, there will be no bull runs for altcoins and people shouldn't really keep holding their coins, and tokens hoping that there will a separate bull run for altcoins and then they will sell their assets. I have never seen that happening in the past and I don't think things have changed.

Altcoins will start going up along with Bitcoin because when people start investing, they invest in altcoins as well and that is what causes the bull run in the first place. There will be no bull run if there is absolutely no demand for Bitcoin or altcoins, if more people are not willing to buy, the ones who bought earlier won't be able to sell their coins at a higher price.
