Can anybody explain me how this works:
Circulation supply and max supply show both on coinmarkedcap 998.999.495 ARDR,
but network is still producing Ardor coins via pos mining.
How can there be already that max supply and circulating supply have the same value ?
the current supply is the amount of coins mined so far and are in peoples wallets and the max supply is the total number of coins that will ever exist on that particular blockchain, if that max is reached, then it becomes the current or coins in circulation
That is not correct, there is nothing mined. All coins went from genesis account to users. No more coins will be created. Forgers get coins from fees, that's closed circle.
