Well, I'd be very intrigued to see what happened if that did come about. It would certainly be spectacular if nothing else.
I never understood why the block reward isn't adjusted gradually (each consecutive block having a slightly lower reward), rather than by halving it every X number of blocks. Any idea?
Easily predictable and accountable money supply. 50/25/12.5 etc. is a lot easier than .000135323 less reward next block.
