Nic Carter explains the most contentious part of Bitcoin's quantum problem: who gets the 2.5M coins that can't migrate? "The worst case is someone that is not a friendly secretly recovers all those coins. And then in a space of 10 blocks, broadcasts transactions spending all those coins to their address." "So it happens very quickly, then Bitcoin is thrown into chaos because people see this. Oh, the Satoshi coins all moved." "It all happens at once by the way."
