Exactly, the way to minimize losses is not to add to other losses, meaning you have to stop betting and never add other funds to recover losses, because there is no guarantee that you can recover losses and you will even add higher losses. So the basic rules of gambling must be to set a gambling budget as minimum as possible for gambling use, this is to prevent you from getting depressed and stressed from losing gambling and also anyone will not have a problem with losing minimal funds in gambling.
Gamblers have all it takes to add minimal amount to their bankroll, but fail to, due to the same issue of not acknowledging the control they've got over themselves. In a losing streak, the interest of a player doesn't coincide always with the casino. Players a times, myself inclusive, feel a strong bargain of who gains the most control between them and the casino. As tough as it may claim to be a tug of war, players often lose out on this bargain, because they're losing the game. Sincerely, it's very hard to stop when we're on a losing streak. In addition, self reliance on the casino for money, put gamblers in a vulnerable position during this battle of control. While we all admit how sweet in the ear it sounds to advise players, the difficulty to apply the advise is what should be a top priority when having gambling discussion.
