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.
