I never tried this, but I guess it depends on luck. Keep in mind that roulette is usually at least 2-3% house edge for b/r because of the 0, 00, and 000. You could make an experiment with dust, if there is a casino that takes it, so bet with 5242 satoshi and see what happens. That would be interesting! you would have to make a win/ lose condition. Lose is obviously you lose your money, but maybe the win condition could be that you double your original wager.
Of course I no that 2-3 house edge ,, I meant in online gambling sites you can bet in whatever amount you like , And this is just a discussion in case of you can bet min 5K satoshi ,, thanks for your opinion bro
