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?
Circulating supply does matter to some extent when I'm considering investing in a project, but it's not the only factor. A fair percentage of the max supply in circulation really depends on the project, its stage of development, and its overall potential. If a project has high supply coin, then likely the value of each coin would be very less. If the supply goes high all of the sudden, this will indeed crash the price of the coin. If a coin has very low supply, it might raise some concerns, because very likely the developers are using the low supply to manipulate the market. The main thins is, you should dig deeper into the project's tokenomics, roadmap, and see how the team plans to distribute the coins in the market. If the project has a killer usecase, I doubt supply would be an issue.
I believe that there isnt a 'one-size-fits-all' answer to the fair percentage of the max supply in circulation that would make a project attractive for investment.
Regarding low supply coins, wouldn't it be rather hasty to infer manipulation on part of the developers? After all, a low supply doesn't inherently signify market manipulation!
I do agree with your view on the importance of the project's tokenomics and roadmap. It's always critical to dig deeper. But your point about a killer use case potentially overriding supply concerns—aren't we treading on thin ice here?
