Hello, I know martingale is useless for long term for dice game but if you have a big bank and can support 1 serie of 20 loose, you will always win no ,?
The world record for the roulette is one serie of 26 red , it will never happen again,the odd are just very low
So if we do martingale with a bank that can support 20-25 loose, we will definitly make money
Nope.
First of all, there is absolutely no guarantee that you will only lose 25 times in a row. It doesn't matter if you have lost 2 or 25 in a row - with a house edge of 1% on most crypto dice games, you have exactly a 50.5% change of losing again. Assuming otherwise is known as the Gambler's fallacy. The world record is actually a series of 26
black in a row, and millions were lost during this streak as gamblers wrongly assumed (as you have done) that red was more likely to come up next.
Secondly, assuming an initial bet of only $1 (and therefore, a profit on every run of only $1), the bankroll needed to support a losing streak of 25 is $33,554,432. If you are willing to risk $33.5 million to potentially win $1, then I have a bridge to sell you.
