your answer is very interesting, as far as I know Bitcoin has a total supply of 21 million, but for altcoint that has a total supply that is not much different from that in Bitcoin, what's wrong?
the numbers above are circulating supply meaning the coins that are released, distributed, mined,... for example there are only 42 coins of 42coin!
in comparison the current circulating supply of bitcoin is a little over 16,800,000
there is nothing wrong. it is just supply and demand. when there is only 42 coins available the price of 1 whole coin goes up. when there is 1 billion coins available, the price goes down. it is supply and demand.
