The expected amount is always 98% percent of what you put in, so the optimal strategy is to not play at all :) It depends what you are optimizing for. In most cases playing multiple times will make you win very slightly less in the median case, countered by the fact that you can win multiple jackpots (obviously not too likely an event) And stopping strategies usually mean having a big probability of winning little but have a small chance of losing a lot. Basically a reverse lottery, but you still lose on average.
