@Febo. 20 years, grin's inflation will be lower than 3%. The price will depend on adoption.
20 years is an eternity in crypto, Why couldn't they just put a reasonable inflation rate at the start for grin. Tech can be great but if price doesn't pump people wont care.
You cant start with reasonable emission rate. You start with 0 coins. then you add first day some coins and that day inflation is infinite. Second day you add same much emission ass first day and that day daily inflation is 100%. Third day you add dame and daily inflation is 50%, .... You cant do it lower. It was same with Bitcoin. First days emission inflation was huge.
The issue most people have though is that GRIN won't have any halvings, it'll keep going with the same rate.
Some people find the halving as an insurance for the future, personally I see it as a pyramid where the few who found out a project early become millionaires if many poor souls join the party later.
