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?
These forms of gambling are usually common in the streets, where people may be pressured into gambling with their valuable materials, like their phones. I usually see them once in a while, but I'm not someone who will be pressured into gambling with something that I know is valuable to me. I attach a lot of personal value to things I own, and I struggle to even sell them off even after I get replacements.
If you have someone who already has the character of using your valuable materials to gamble, as time progresses you may lose many of your important things when you want to gamble, or maybe you do not have money to finance gambling; your properties will become an alternative, and that is not a responsible way to live.
