It's exponential growth man, you take your entire bankroll (let's say $20). Bet 10 games at $2 a piece, win 7 of those games. Add your profits to the bankroll and bet the entire thing split into equal parts again. Repeat for infinity.
Do some manual labor jobs or help old ladies load groceries, rake leaves, etc. Once you got about $10 you could bet every game and turn it into a million before the month was out
