Silver is a lot more affordable for now (as far as per/ounce)…and seems to be what lots of people think has the most upside. Lock it up in a safe and leave it alone until the day comes that you need to sell it or barter with it. Good luck stacking.

There may come a time when precious metals extend to brass too. It is always prudent to have several options to barter. Each option has it' s own merit. Silver is important because of it's antiseptic properties. Gold is important especially on a monatomic level to sustain human mental development, etc.

But there are times when little flasks with whiskey, vodka, paper towels, napkins, condoms, toothbrushes, etc, may yield much more in terms of value.

Hence diversification.

at 19 best advice is to get licenses to sells stuff. Anything you have an interest on:

things like real estate is big money. THEN, you can buy whatever tf you want.
