Apart from real use case do coins and tokens max supply counts as well? for example lets look at doge coin,its max supply is 280 billion and the circulating supply is 120billion which is presently trading at 0.0026$ what would have happened if its max supply is in millions ?
i think some coins have way to much max supply which actually affects the coin or token performance as well,coins with low supply will always have better value than having gigantic supply.
Supply is one issue but it's not the main issue why the coin is losing its value in the market, coins/tokens are losing its value in the market, because the concept is not enough for a long term, investors have a very short attention span, they jump from one coin to another because the coin is not performing and developing well and it's not about the supply.
There are coins being burned to lessen the supply but it still not helping the price to move.
