Yes i agree with you. But when you limit the profit and exit at right time, chances are more to win. At least you may not lose more...
The problem with most of the gamblers are, they expect more profit. They are tempted to play more and more.. Finally they end up losing it.
Limiting the
payout profit you attempt to make and exiting the game do not improve your wagers' expected values, which are generally negative for gamblers.
To be successful, one should not play on the same site always. Just make a small profit and exit from that site and play on a different site. If we keep playing on the same site again and again finally we will lose the entire money.
Example:
Day 1 - Play at x site and exit with a minimum profit.. (may be 1 percent or 2 percent or 5 percent)...
Day 2 - Play at y site and exit with a minimum profit
Day 3 - Play at z site and exit with a minimum profit
Now we have loads of sites to play with...
This is
gambler's fallacy. Playing on a site for an extended period of time doesn't decrease your chances of winning there. Likewise, waiting a day before continuing to play there doesn't increase your chances of winning.
