as in the title. im fairly sure I found a +EV method for a particular dice site, if someone like dooglus would pm me to confirm for this I would consider selling this bit of info to a few people. just being +EV goes not guarantee massive profits because this is gambling after all, but it is +EV. this does not involve martingale whatsoever.
Considering you're willing to sell the method it doesn't seem as highly profitable as the buyer might think since otherwise you would just use the method on you're own.
