The logic behind this betting method isn't complex at all. You bet $2 on x2 and on the next bet you sum +1 to the bet amount and it looks something like this:
$2 - x2
$3 - x3
$4 - x4
$5 - x5
...
$10,000 - x10,000
I know, in the example looks like a lot of money to bet, but now think about starting from 0.00000002 BTC or better known as 2 satoshis, with increments of 1 satoshi, you can be betting in the long run with 0.001 btc.
To do this I hire a guy to make a betting bot for a casino, and is looking good, is really hard to find a losing run with it.
So, what do you think about this betting method, Has someone tried it in the past?
In short, something important is being forgotten: the "ballast" of the liability of each bet and the decrease in the probability of winning by increasing/changing the multiplier. That is to say, in betting round #3 the bet is not $4, you must take into account $2+$3 and to that you must understand that increasing the multiplier decreases your chances, and that randomness can sink you into a round of betting where that multiplier does not appear.
In his case, he has the perfect "paradox", he is not only going to win, but he also obtains a higher profit, a man who invented the wheel for casinos.
And you don't see the negative results because the amounts are small or you haven't had a long loss line. Changing the multiplier affects the probability, consequently I would have to use stop lose for the amount in which it is not fulfilled.
For those who say; this (OP) is martingale, no it's not:
#1 bet $2 win 2x=>4 so 4-2=2
If not successful:
#2 bet $4 win 2x=>8 so 8-(4+2)=2
If they don't succeed;
#3 bet $8 win 2x=> so 16-(8+4+2)=2
Your profit will always be 2. Or the initial bet.
The OP thing is the paradox of "El Colega," please, man if it works, we reinvent the game. I say if Martingale is TNT for your bankroll, that technique shown is "Oppenheimer"
