What is the fair percentage of a total max supply that are in circulation that can make you invest in a project? It is fine to avoid a project that has low circulating supply? Why? What about if the project is a brand new project and the use case is killing it?
Low total supplies have the potential to make the price of the coins rise higher like what we see from the current top altcoins nowadays and also add the event where they burn some coins from the total supplies, it will gonna make the demand bigger and the liquidity healthy but these things will not gonna happen just because of that. other important matters are needed as well, especially the credibility of the owners of that project and also the team behind it because if they are totally unanimous and they are a completely new team with no known credentials, all those traits for a coin is nothing.
What does individual coin price has to do with anything with the percentual rise growth, demand or liquidity? What about decimals, do they need to be lower too?
Anyway, only thing that matters regarding to tokens is their issuance rate as that might cause inflation, so staking / mining rate needs to be unsustainable. But this has nothing to do with max supply as it applies to low supply coins/tokens as well.
It is true that it has nothing to do with it, however there are many newbies out there which see the high price of bitcoin and think that coins like dogecoin or ripple have greater potential as the price of each coin is on the low side, forgetting the massive market cap of those two coins and how this is a very important factor when it comes to trying to determine the potential gains a coin may give, so taking this into consideration it makes more sense for developers to create a massive supply for their coin as a way to try to keep this idea on the minds of newbies for as long as they can.
