  • Gold Chloride

  • and because of it's rarity.

  • and because its rarity and beauty,

  • Money is just an illusion!

  • When he refers to storing gold and it never changing, its not totally in reference to the value, its about the physical form. Gold submerged or exposed to water forms a slight crust that can be polished out, this crust also protects the rest of the gold from oxidization. Silver on the other hand corrodes strait through and must be rerefined. This makes gold preferable for long term wealth storage, not just because of it value but because of its resistance to corrosion.

  • you know the price of gold fluctuates, right

  • He's referring to storing your money under the form of gold.

  • No, the value of gold stays the same. It's money that's variable Do a bit of research, you'll see.

  • Very nifty video. Haha, he said all your money can be put away and it will never change. That's of course not taking stock markets and globalization into account, haha.

  • Really excellent video! It stands out from the others as it seems less technical but more "alive". Nice to see variation in tone.
