imagine how scammy this scheme gets if they would also add something that gives out interest when people hoard coins! now the instaminers can slowly offload (drk i am looking at you)

i think that if a coin is published some features should not change or it is like betraying your investors. this includes pow or pos, max coins, time between blocks - everything which changes the money supply or the way coins are generated should be kept fixed (i dont think block size matters though).

if a dev really wants to make a few changes he should just fork his own coin into a new one and initialize it with the blockchain from his original coin. that way his investors can decide which route to follow.
