But I noticed that the pump/bull run that we experienced last 4 years are better compare now because of the massive price increase both alt coins and top coins, not unlike what we experienced recently which only few and selected coins pumped.
Is that the basis of a healthy bull run?
Those coins you are talking about way back in 2017 are mostly products of a hype that even without a use-case token, it can increase the price.
Going back today, there are lots of altcoins that also got pumped up on this bull run so I don't understand why you said it's only a few coins that got pumped up. Maybe you are pointing at those coins you have on your portfolio?
