I was reading about Cashaa, that was hacked and 336BTC were stolen. But the hacker can't move them right? He will leave footprints. So why should hackers steal them since they can be found? For example if they want to convert them to fiat.
I believe you forgot about Mixing company or you have no idea about that?
Hacker can easily send the amount to mixer and then boom traces are gone.
and also i believe that the hacker can put the Bitcoin in gambling sites and then make some roll before taking it out?or they can be a gambler itself so betting will be the place of these Bitcoins.
The only way I think you could get by from this felony is to keep them on very long term. So long that it may be forgotten. But still, it may.
it will never be forgotten mate,unless the claimant died before he took the bitcoins out.
and how would we know that hackers will still alive when the time comes?
the best way to spend the bitcoins is to Gamble it.
