If you are playing dice just try to extend your luck as long as your strategy wins and and soon as you feel like the luck runs out just withdraw and run because no one wins the long run and that is how gambling sites are designed and if you keep on chasing the losses you will end up losing everything.
The problem is that when we are in profit and we stop then we feel we could have made more profit while when we loose we think we should recover the loss given to the site.
