At that point the price will go up and all of us will have some of the coins. Maybe they started stolen/scamed but their Karma would be re-incarnated into the good Karma!
If you are in PM me or post here I'm happy to co-ordinate or support whatever we do with this and get this going.
I like that idea

I'd be willing to forgive the (known) person who stole the coins and used them for his/her own benefit. But of course they'd have to publicly apologize, which I am certain they would never do. I'm sure the Karma community would be, too.
(Though it's kind of sad that there are more people perturbed by me starting a new coin that by the person who stole billions of Karma)
