I think supply doesn’t matter for a good project which they have larger investors community. For a meme coin there is billions supply so that's why there gone to death quickly. But low supply good support for price rising. Even if they have million investors planal then supply not matter for price.
No man, people keep seeing it as one of important metrict. Infinite supply will give a very bad impact to the project in the long term. Have you ever heard the SLP token? this token was acting as a reward for the players to play axie but this token is die right now. It's caused uncontrollable supply.
