so with a 12,000 initial supply at 2000% annual stake.
Supply after 1 year = 240,000
Supply after 2 years = 4,800,000
Is that math right? will there be a cap on the supply?
No, with 12,000 initial supply coin will have 3,431,247,062,843 after a year (compounding is great

). In ideal conditions of course - full supply staking 24/7/365.
