Hello I know I watched every roll and up to the point it started blowing through my account it seemed it was using a lot more than 1% per roll. I went from 300 to 800 in a number of seconds it seemed to be going through my balance much faster.
The screenshots looks fine to me there's nothing wrong about their dice. You think the auto bet feature using more than 1% because you forgot that decimal values add up too.
When the bet amount is 880 sats you thought the increase is only going to be 8 sats flat which isn't the case and it should always stay like that since it's based on percentages.
It's normal that you can go from 300 to 800 in seconds with how fast Fortunejack's bet speed is even with dust bets it's quite fast compared to others.
