ım gunna hıt martıngale on satoshı. but you really need to use the 48% one because thats the best. even black red ın roullette ıs 48% because people often forget about the 0 ıf that hıts neıther black or red wıns but ıts VERY rare
At Just-Dice.com the house edge is only 1% compared to 1.9% at satoshidice. The bets are instant, and you can pick the exact chance of winning you want.
The black in roulette is 18 in 37 or 48.6486%.
Just-Dice.com pays out 2.035x for that chance of winning, compared to 2x in roulette and an effective 2.0165x at satoshidice (if they even offered that bet):
The max bet is also higher - you can bet up to 532 BTC at those odds at Just-Dice, compared to around 200 BTC at satoshidice and 100 BTC at the biggest BTC roulette game I know of (bitzino).
Oh, and zero isn't "VERY rare". It comes up 1 in 37 spins, or 2.7% of the time.
