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.
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.
There are 2 things why bitcoins can be hacked, the first is the carelessness of the owner and the second is an insider's job, that's just my analysis, I know Bitcoin cannot be hacked, because it is always safe for all users, we all know hack cases are not only happens to cashaa even more than you know, as usual they keep it when the time and the price increases they will sell it, but it looks like it will not affect the current and future bitcoin price even though they sell it
