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?
I haven't and I will never try such since I have stuck with the habit of bringing out 3% of my monthly salary for gambling alone and not going above it.
Staking valuable materials into gambling is what I never learned since I am not gambling to make sure, I make riches out of gambling but instead to entertain myself to try my luck if I can win little or no money from gambling.
When a gambler becomes addicted to gambling, they are ready to stake their valuable products to see whether they can win. Since I am not one "addicted gambler", I will only be betting the little I have, and not to be staking with valuable materials which I can't afford to risk and lose to gambling.
