My question is, can you remember a time when you reached your threshold of loss while gambling?
A true gambler doesn't have a threshold loss, one would only stop if there is nothing else you can sell to gamble with.
Unfortunately, not everyone is a true gambler so many of them will decide to quit.
But some gamblers continue to gamble and deposit more money to recover their losses.
Many of us can stop before we lose our money and take a break to lower the tension after playing gambling and this may have something to do with the threshold of losses while gambling.
It is clear that when we almost lose all the money, it is better for us to quit than to lose all the money.
