I don't know much about the inner workings of bitcoin, but they know what wallet the stolen coins went into and where they went from there. Is it impossible to black-list the tainted coins/wallets? If every single transaction is in a ledger, then wouldn't every single coin be traceable?
Yep stick to your day job, blockchain aint for you son!!
Instead of making useless comments, perhaps you could explain why the system cannot be used to track the stolen coin? It seems that users were quite successful in watching where it went from the nicehash wallet.
