I always thought that initial coin price is not important, because there is no difference between buying 1000 coins at $0.001 or 0.001 coin at $1000. Buy most of my friends who are newbie in crypto prefer buying low cost coins ("BTC is already $15000 but Rillple is still cheap").
Maybe that means that new people coming to crypto would prefer new altcoins (especially altcoins with lower price and more total supply) rather then BTC, ETH and other > 1000$ 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))
