It is really a no brainer move to burn down 18 BTC, whatever we calculate the price is still of the current market value.

Being a hacker involves being smart, forceful entry is already part of stealing, whereas completing the task that the whole BTC should have been used to aid his country, since it wasn't done for personal interest.

Is Israeli government going to apprehend the hackers, or are they to see it as a positive retaliation?
