Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.

Risk of ruin is a concept in gambling, insurance, and finance relating to the likelihood of losing all one's investment capital or extinguishing one's bankroll below the minimum for further play. [1] For instance, if someone bets all their money on a simple coin toss, the risk of ruin is 50%.
The correct strategy is a Kelly bet or a fraction thereof. The Kelly criterion suggests betting 20% of bankroll each time, adjusting the amount of each bet as the player's bankroll goes up and down. Assuming a player can make 300 bets in 30 minutes, betting 20% or 10% of bankroll both have a 94% probability of reaching the cap.
