It's also a good idea to buy stocks when they are low, and sell them when they are high.

Betting strategies should be viewed as for your own entertainment. The underlying probability of the game never gets better or worse because of a betting strategy.

But viewed that way, Just Dice gives you the chance at playing lottery style bets without the lottery commission taking half your money. Max payout is 990,000x in JD. If you want to buy 1000 million dollar lottery tickets for $1, then the overhead is about $500 at the lottery. On JD the overhead is $10, and all of it goes at the jackpot instead of wasting away on mini payouts.

Factory workers who pool their money every week and purchase a box of Powerball tickets would be better off if someone would place that money into JD. They could produce a paper and show where every bet went, not like those cases where one ticket is mysteriously replaced, only to be claimed 6 months later.
