Betting 4 percent of your bankroll on any one game...and winning 10 units a month will increase your bankroll 4000% after 10 months. I calculated this by upping the wager at the end of each month to the new 4 percent from what the 4 percent of bankroll was the previous month.
Breaking that down further, to achieve that kind of an increase, we as bettors only have to win 2.5 units a week.
Say we had a mythical 10,000 dollars in our bankroll
We would be betting 400 dollars per game our first month.
If we won 10 units a month with a starting stake of 10,000
Month bankroll won balance at the end of the month
That's only less than a half unit a day....after two months our stake will almost have doubled...after 6 months it will have increased 10x, after 8 months our bankroll will have increased 20x and after 10 months, our bankroll will have increased to 40 times its initial value.
