Minimum bet size?

Let’s say that a broker has minimum stake of £10.

And also let’s say that we start with a bankroll of £1000.

How can we modify Kelly criteria in order to avoid Rebel’s suggestion under minimum stake amount??

Can’t you just round it up to £10. If it’s a +EV bet then it’s more profitable in the long run. You can also use a flatter staking plan to disguise your betting and not get limited.
