oh wait, no ceiling on number of coins? That would have to be settled. I don't think we messed with ceilings yet, and int64 only goes so high in any event so would itself impose a ceiling...
So give away 1 coin per block and let maxint be your ceiling. Those two factors combined would give you a LONG time before you have to worry about inflation stopping... And by then int64 might seem as quaint as int defaulting to 8 bit is to us today
