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.
It requires big capital. This strategy won't be successful everytime. Even if it had won, then the user will make a profit of $20 after a series of bets. Very few will have such mentality to risk such a big amount expecting a win of $20. These days almost every platform have got the provably fair feature and have got the seed with which we can examine the real functioning.
