I don’t know why copper but gathering a list. One might be the increase need for electric.
One downside is the Chinese can use holding gold as leverage against administration like the current one too.
Your right about the Chinese and gambling. I’ve been to casinos a couple times with friends years back cuz they had a good buffet there until COVID anyways. I’m not into gambling but was quick to figure out systems they may have too. Those Chinese if they see you winning they follow you. I was winning in the slot machines but stayed low key winning and they didn’t know it so what they’d do soon as you stop they’d hop on thinking they were gonna win. Then the next time I was on the quarter keno or something machine and saw a familiar number pattern ” no accident” so started winning and the machine would make all these noises when I’d win and get bonuses and this Chinese guy just knew I was using numbers per patterns and sat down next to me and pretended he was drunk and leaned over so far his face was right in front of the window of the machine I was using and had to push him away at yell at him and left. You have to be aware of who’s around you especially if Chinese but at least they didn’t follow you out. That’s another type.
