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))
The price is not the most important indicator, there are factors such as market behavior and its liquidity and, of course, support from the developers. There are shitcoins that no one needs, and there are promising coins according to the type of stratis.
A good sign to look for are coins that have a low market cap but that have a big activity when it comes to volume, those kind of coins have a tendency to go up since there is a lot of interest in them I have used that sign to find some really good coins that eventually gave me some profits, as you progress and learn more you will be able to interpret those signals and invest in the good coins and avoid the bad coins.
