Have you ever gambled til you don't have money to stake on for further playing then you take a different dimension of staking with a valuable material?
Why will I gamble to the point of dropping a collateral to continue gambling. That is a sign of chronic addiction and anyone in this state needs to see an expert for rehabilitation, otherwise, his condition will worst. If you find yourself doing such, you need to quit gambling because you will run at more losses and become frustrated in life.
You might not be like that, and that's good to hear, but sad to say, there are some that are willing to trade their valuable material for money just to use it for gambling.
I've seen it first-hand when my neighbor got addicted to gambling that it came to a point where he are selling his appliances for money, selling all that he sees on his house just to have money to be used for gambling. Obviously, he's addicted to gambling, and the bad thing? Nobody can help him at that time. To cut the story short, he isn't on our place anymore as he left, and I'm just hoping that he's ok now.
Getting addicted to gambling is very easy, but quitting gambling is very hard. If you can't control yourself, I would suggest not to gamble at all.
