So why would anyone bet anything more than 0.1 BTC?

Think it through, this is the 3rd time you failed.

Because you will anyway get your bets back. Even if it is 10 times higher than the others - I send it back with 90% profit of all the rest bets.

But why would I do that? I won't make any more money, and it increases my losses.

Thanks for the patience. Fixed the amount. LOL
