I know very little about stacking or investing in precious metals. But once in a while I will see someone recommend stocking up on gold or silver. Lin Wood also recommended this so it piqued my interest.

Since I know very little about this stuff, I'm going to do my research before doing anything reckless. But every time I see a question like "should I buy gold or silver?" being asked on reddit or quora or whatever. They always get flooded with the generic "don't buy gold/silver, it's a bad investment blah blah blah".

I always see people telling others to not buy gold or silver but their actions suggest the opposite. If it's so bad, why are there still tons of people out there trading like no problem?
