Do only 50% bet 20$ every time if it fails do 60$ it fails do 150$ if it fails do 350$ if it fails do 900$ if it fails do 2300$
There is no way you will fail 7 times and if you do just increase the bet and you will get it back eventually even if you wait 12 times.
what you think on my method?
requires a large capital to do this way and the victory that will be obtained in the end is the same as a strategy to play casually without rushing. That way, in addition to the large capital we have, of course, we must choose a site that is proven to be fair, lest the bets that we multiply continuously cannot return the capital we spend.
No, large capital is not enough to fund this strategy in a long run. This strategy needs an infinite amount of money. Martingale when hit by a red streak is devastating. Even with a 98.5% chance of winning, a series of red streak hits a dice session what more for a 50% chance.
I followed this strategy in many times specially in CASINO but i lost big amount of money, because you can't win every bet. Even i waited 15 times then i have no dollar to bet for next one, as a result i lost everything. So, i would like to recommend don’t start bet with big amount like 20$, you can start 1$ if you have big amount then start 5$-10$. There is a high possibility of losing everything if you get too greedy.
Martingale is not a good system because when you think about it, there is always a chance to lose, and when you do, the loss will be greater than your previous winnings. This means that over time, you will lose more than you win. The only reason why this system can seem like it works is because people tend to have winning streaks and losing streaks—but the Martingale system won’t help you avoid losing streaks.
True and we know that in a Martingale session of 50%, a 10+ losing streak is very possible. You can check this other forum conversation[1] about their losing streak on dice. If I am not mistaken someone in that chat experience a 20+ red streak, so if that person uses a martingale method then with a base bet of $1 he could have lost more than a million already since at 20 losing streak his last losing bet would be around $524,288.
In short, OP's strategy should be avoided if we don't want our balance to get depleted in an instant.
