From 7023 to 7016 within 2 hours. That is some seriously bad luck. I think at the time the price was $100/BTC. He lost $700 in 2 hours just by investing.
A few days later the bank made 2,722 in one day. Since I am sure betting was not uniformly spread throughout the day some hours may have jumped up 300 BTC. Someone who was invested at 7K BTC would easily have as much as 20% of the Bank. So a change of 7 BTC in two hours would not be particularly shocking.
I can see how you get death threats all day.
Those are the kinds of things that psychotic people say. You need some serious help.
