I propose that an altruistic coin is one whose emission doesn't favor its creators or early adopters.
It should favor the late adopters.
One such emission is the simplest one possible: one coin per second, forever.
This is trivially implemented by having a fixed block reward (subsidy) equal to the block interval in seconds.
Altruistic coins avoid wealth concentration and deter speculation, while encouraging use as a currency.
After several decades of wide distribution, they have inflation rates comparable to fiat, but unlike fiat,
this rate remains perfectly predictable and ever-decreasing.
There should be more altruistic coins...
