The perfect theft in crypto is claiming that a project or an exchange is hacked when its all an inside job, the reason why I think about this is I have never heard about other top exchanges helping a exchange that just got hacked to track their funds and get some back at least but if it's a sole hacker from outside they will track him or them down, why is that?.
Yeah, that's our speculation that there's an inside job.
But there's no need to think about it if the exchange has been dropped off a lot with their losses through that breach. And why would another exchange will help a hack, a loss that has happened to the others?
They should be prepared to any possibility if it's related to their funds. They should have a safe for which they will use upon experiencing it but hopefully, won't happen to all of them.
