You see, the max supply coded is 63 561 840 coins (ref: main.h). So far, the network has produced 62 683 254 coins (getinfo). Leaving only 878586 coins to mint. When the max supply will be reached, in about a month --> no more rewards from minting = miners leaving = no (or very slow) network = no transactions possible = dead coin. Unless, the miners wants to mint for nothing, which is possible. Should be interesting...
ppl staking worldwide should provide enough hashpower for the network, i believe
Yes but after a month there will be no coins for staking, so unless people are going to stake for 0 reward the network would die. So to keep the network running even once the stake os paying 0 people will have to leave the wallets open staking for nothing. The coin has been widely distributed though so is possible enough users will do this and keep the coin alive.
This is a misunderstanding (on the part of the original dev).
The 63561840 is the maximum amount of the coins you can transfer.
The total money supply is unlimited. So with the code as it is
now, staking will go on forever.
