20 Million is the total amount of tokens that will be released in the family’s entire history, not more, not less!
8 Million GANG tokens (which are included in the total 20 Million) will be released over two years for staking. Staking that will be available in two ways, so by earning them directly from a dedicated staking pool or by taking a position in an automated play pool.
Over those two years, staking tokens will be released based on this planned block reward schedule. At the end of this two-year process, staking rewards will become insignificant. The Family will then switch to a fees redistribution model.
