What I think would be the best is not to change block rewards but block time, it will lower inflation and extend mining period of a coin.. coin is too fast..
But hey, I don`t think no one ever tried something like this before.. it is OK to make a mistake, but it needs to be fixed and we can watch the experiment unfold..
I didn`t invest, just mining/buying.. but I think investors need to decide not CEO, without investors there would not be any CEO...
