Maybe that means that new people coming to crypto would prefer new altcoins (especially altcoins with lower price and more total supply) rather then BTC, ETH and other > 1000$ coins?
Also with cheaper coins it's simply easier to calculate whey purchasing something with crypto. I'm sure everyone is using calculators while trading on BTC/* pairs))
I agree with you price should be not important things but newbies don't understand what is total supply and they think that low price coins are better to invest. I think because of that low total supply coins pump more often.
