I am working for a payment processing company, and we are monitoring suspicious activities all day long. So you say somebody hacked the system and just liquidize enough hash rate to drop market value 80% right use your brain at least one time in your entire life and if you have any proof showing otherwise, I would be really happy to hear it.

By the way, still sell hash rate function active so if there is a hacker, still have chance to sell more right so good for him/her (no gender discrimination)
