The idea of putting back lost Bitcoins back onto block rewards seems like a great idea.
I acknowledge that there were quite a handful of early adopters who were generating blocks daily, but had no idea what they were doing. Time passes, they forget about Bitcoin and they format their hard drive or whatever. Their coins enter the nether, never to be seen again.
I wouldn't be surprised if >5% of the current coins in circulation were lost due to mishandling. My question is, why isn't there something implemented for this? I can't find any disadvantage for this feature, it would simple as invalidating coins that haven't been transferred in
x amount of time, which is probable for only sorting lost coins.
