Those bitcoins weren't locked? Far as i know those bitcoins were locked in a wallet that would never be opened again, i dont know, but can anyone explain me how the fuck are they going to hit exchanges soon?
I think a hard fork locked some years ago, but the theft went on for 4 years so lots of wallets were used.
Most are still in wallets and the idea that every coin can't be put back together is wrong, a nice computer can take the blockchain and go backwards and forwards showing where every coin belongs
Every transaction is in the public ledger so it's just data manipulation of the ledger
