Today I researched the money supply rates for some crypto currencies, namely Bitcoin, Litecoin, Dogecoin, Dash and Monero.
They use very different money supplay algorithms.
- Bitcoin / Litecoin
- The block reward is constant, but it halves every 210000 blocks (840000 for litecoin).
- Dogecoin
- Simply 10000 doge for every block.
- Dash
- The block reward depends on the actual mining difficulty. It is
0.9*max(5, min(25, 2222222/((difficulty+2600)/9)^2))
every 210240th block the reward is reduced by 1/14th - Monero
- The block reward of monero depends on the currently existing amount of coins. It looks like this
max(0.6, (2^64 - 1 - coins*1000000000000) / 2^19 / 1000000000000)
With these facts we can forecast the inflation rates of each currecncy.
