Not only are the winnings multiplied exponentially but so are the odds of failure
The odds of failure have not the same exponentiall as the winning goals. I have uploaded new version.
As you can see, at day one the winning goal is exactly 1% from bankroll.
Hardest day is day 14 with winning goal 7 % from bankroll.
Than it is getting easier every day.
Day 365 you only have to win 0,54 % from your bankroll.
