All amounts will be refunded it just has to be in the same %chance. For example if you use the martingale system yout 1, 2, 4, 8, 16, etc.. will all be refunded.
All amounts of a consecutive bad streak, just the first 10 or just those after the first 10?
After 10. But we may be increasing this soon.
For example, I bet and lose the following rolls at 50% chance: 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 1, 100. What would I get refunded? 101.09, 1.09 or 100?
As it stands yes
Yes what, BTC100 (the 11th lost bet)?
Yes.
