They were possibly "hacked" but the so called hackers took advantage of an exploit in the site whereby they could get double their BTC and they bought up BCC tokens which initially drove up the price to $150+

The perpetrators then transferred those stolen funds to other websites and DUMPED on the market causing that drastic drop. The lack of buy orders past a certain point is why the price flash crashed.

The website came back online and explained some of what happened and even payed out 4 missed days. If it was an inside job they are pretty smart and they picked up a bunch of cheap BCC tokens after the crash. It is looking like certain users actually exploited the system.

BCC has a bright future if they can prove they are not in fact a Ponzi or pyramid scheme. I think there is a lot more money to be made off of them in the short term.
