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))
As you can purchase a more coin from investing in other currencies with a lower value, you can feel the profit in every increase it takes in the market. But keep in mind that this does not mean that you cant earn bigger with the major altcoins in the market. BITCOIN and ETHEREUM for example is a well established coin and has a lower chance of being bankrupt. I suggest to analyse the currency that you would like to invest and take precaution as you go. it will also be wise to split your initial investment to maximize your capital.
