The best strategy is to play till about max 500 rolls beyond that its not safe.
There is no hard and fast rule that your safe in less than 500 rolls. I got few times around 6 to 8 continuous losing streaks before reaching 500 rolls.
-> you will always lose in the long-term, so better withdraw every here and there
If one is an addicted to gambling then no use of withdrawing because they will again lose back that money to the site soon or later. So the most important thing is to try to avoid gambling every day and play once in awhile.
