"what about these coins? premine? - fud"
but then again..
"deleting these coins is not adequate"
so? if someone did not claim them and D9 is getting this ridiculous shitstorm, I would say:
Call out for the dude(s) to claim the coins in a defined time span. If no one is answering, leave them where they are. Everybody knows where they are. But to be sure this argument can not be recycled in the future, the coins should be made unavailable.
If you insist on D9 giving answers to questions he may not know but simultaneously insinsting on not to invalidate the coins, then the discussions end is well beyond horizon.
