Maybe the max supply is not very important as you have seen. Look at the market, there are plenty of coins even it don't have a limited max supply, still fetch for a good price. A good use case is far more important than try to hold a coin with limited max supply as its main attraction.
Obviously, a good use case on a product from a project is a very important thing to look at rather than keep the coins at a max supply, because we can see the progress of a project through the number of products used by everyone in real time.
