you must be a millionaire or even a billionaire and you wont even notice a loss, for example $100,000.
Even if there might have a loss and the more anyone takes the risk the more anyone may lose. For example, you have deposited 100000$ to a casino and started betting with $1. You made a loss then place a bet for $2, in the same way, 4$, 8$, 16$, 32$, 64$, 128$ 256$ 512$, 1024$, 2048$, 4096$, 8912$. Already you made about 20000$ losses. If the site has no limit then you will lose all of your funds in the next 3 bets. But if they have any limit then you may get a few more chances to lose all of your funds. I have seen 18 losses in a single row.
Yeah, I also hear or read more than 18 straight losses, if you are unlucky there's no chance for you to recover and mostly you'll regret playing that kind of strategy, best to play to enjoy and make sure that you know how to control your bankroll, there's a chance that you can quit with some decent amount of profits.
Or, if in case you lose better to quit and take a break for a while, same deal if you win huge, best to quit and enjoy the money that you earned, be wise spending don't over waste your money back into gambling, it will surely be back to the house if you mismanage your money.
