P.S. Any opinions are welcome (because I still don't see any drawbacks, except hard fork )
So are you saying growth of coins (ie bigger subsidy) or less coins (smaller subsidy)?
The first one wouldn't make sense- and the second one has already been heavily discussed.
The network hashrate currently does not affect the number of coins mined in a day. You are aware of this?
I think he is trying to propose a model for the coin reward to be based on hash rate, and that if the hash rate were large enough the reward could be above 28k/day, but if the hash rate is small, it could go below 28k/day. It would help to stabilize the price considerably. I kind of like the idea.
I think if something like this were put in we would need to reconsider the 84mil hard cap because it could be reached much more quickly if the network grew a lot.
Also if the reward were reduced too much for our current low network rate it could look like market manipulation to outsiders, so I think a delicate hand would be required.
