At this point there's only one safe haven remaining for a private citizen's savings: the actual possession of precious metals that no one else knows you have.
Don't count on collectibles; fads come and go too quickly.
Don't count on gemstones; the supply is far larger than most people know, and most of them can now be synthesized in labs.
Don't count on land; nothing is easier to tax or seize, and anyway, you can't move it around.
Gold and silver are the only refuges left. Buy the actual physical commodities, store them securely, and tell no one you can't trust with your life...because that's what you'll be doing.
