That's the sum that was paid to the OPs of the accusations, and this sum exceeds 6 BTC to the day.
Also, the site runs for 5+ years. Quite a long term for a ponzi scheme.
Have you checked our
review thread?
It seems like most of the people haven't seen it yet.
You may be right about the 6 BTC part, but you are neglecting the fact that the amount that you guys scammed from gamblers is way higher in comparison. Also, I have seen several ponzi schemes that managed to run successfully for several years(Ex: Bitconnect etc).
Your review thread is mostly filled with negative reviews against your site.
