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.
It was a shady exchange and i doubt whether there was any real hackers behind the scene and the team behind that might have moved the coins and have went through mixers and expect that they can blame on a hack and never return the customers anything and with the halving and the rally expectation i expected many hacks like these.
