Sometimes hackers make me feel that there are people been sponsored to erase trust in the system. Knowing fully that hacking is a criminal offence that is punishable
I think the same way too.
Hackers are usually a team member or employee of an exchange, or someone who works in a particular exchange collaborates with the IT people to hack the system. Inside job always happen, sometimes its goes unnoticed. But, there are really those talented hackers who could manipulate the system even without any connection from the inside.
