You go to this site and deposit 0.01BTC. You accidentally click roll hi button when the multiplier was set to 10x, rolls a 99.99 and win 0.1BTC.
What will you do?
I would be shocked at first because history proves that whenever I click roll by accident on an unusual multiplier, the result is always lose

but if I win, I think I would bet the starting amount and keep the winnings there in case I got on a losing streak and needed to increase the bet amount a little bit.
