Why didn't you assume betting with 0.1 BTC? You would have "made" 36.4 BTC then.

But seriously, when I read your first sentence I believed it right away for some reasons.
I would chose any number since I was assuming but I wanted to keep it realistic
I used to gamble a lot long ago. There were no single day that I did not gamble for consecutive few years. I lost a lot earned a lot but end of the day I discovered the losing side was more than the winning side. It was hard to give up the addiction but I did eventually.
That's a gambler's mind: we always want to believe that if not we then at least someone else is winning big.
Same here. Thing is it's not only the fellow gamblers who feel good. Anyone will feel good when they see other one is doing well.
