What is the max supply of 808 coin and number of coin generated ?
There is no max supply for 808 coin, its just like Doge which also has no max supply. Now the number of coins you can earn from staking depends on the number of coins you have staking. The minimum most of the community recommends is at least 250k to 500k the more the better. You will earn your staking reward in 9+ days depending on how many coins you are staking. For example 250k will take roughly 15+ days to earn a stake, its around 17% every 8 days but every day after the 8.08 days it adds 2% but its best to try and stake every 9 to 10 days to compound faster and earn more coins in the long term.
