could you elaborate why?
Siacoin, dgb, eos, decred, and many other coins that in 2018 had significant increase in price and hype, we don't hear anything about them today and they did not have any significant rise so far and a lot of them are dead, 97% of altcoins are pump and dump.
those coins failed to provide a valid usecase, its not the quantity of tokens its the fact of no one uses them
for all those dead ones you have compounds, chainlinks, pancakes, bnbs etc that have uses and those hold value
top 30 coins is way way over simplistic, sia fucked themselvs by adding thier own asics and eveb allowing asics for small caps like those , even grin and other mwc tokens never provided an easy way to access thier networks or supported asics in some way and got dumped to hell. samw with that shit coin kadena too , all thesw tokwns you mentioned had stupid teams. Etherum does too but they just happened to be first of the smart contracts capable and web3 tokens and als massive funding behind it
