Elsewhere on this site we have outlined the advantages of a staking system known as the Kelly Criterion: a method by which you increase and decrease your stake according to how “wrong” you think the odds are.
So, if you are offered odds of $2.60 on an even-money shot, you would only have a small bet, but were those odds to increase to $10.00, you would dramatically increase your stake.
There are problems with the Kelly Criterion and other proportional staking systems, though.
