Gold and Silver have always had value, never gone to zero. Can you say the same for stocks and bonds?
Back in 1960, the paper dollar and the silver dollar both were the same value. They circulated next to each other. Today? The paper dollar has lost 95% of its value, while the silver dollar is worth $34, and produced a 2-3 times rise in real value. Since we left the gold standard in 1971, both gold and silver have become superior inflation hedges.
Bitcoin is not an actual physical coin, and if computers are shut down, you can't buy or sell them. That's why nothing will ever replace gold and silver coins themselves, and all investors should have them at home or in a safe deposit box.
Gold is as steady as a rock, a standardbearer by which all currencies can be accurately measured.
