Did he have 30 billion if he made it 100 days? 

Also plenty of folks have made it longer in isolation and not come out totally fucked. Its one thing to do it voluntary its another to be forced and id imagine doing it for 30 billion would be totally different as well.

The catch would be 100 percent convincing the person going in they would actually get the 30 billion. That aint money some game show can decide to let you win.
