I still think mandatory demurrage for x number of blocks is in order to deflate this fat balloon before it pops.
Probably wanna just do like 1% per block for like 100 blocks that should get you down to 1/3 of all coins produced then I suggest if you wanna be fancy, then do continual demurrage of .00001% that is drained into miner fees thus this coin would actually have something unique
actually that sounds pretty cool
.00001% of all coins around getting put into each block
that way every 10000 blocks (38.19 days) everyone is down to 90%
and after a year or about 100000 blocks everyone is down to 1/3 thus people will either need to mine or trade
