GOLDBACKS - Value and Production

https://www.goldback.com/where-to-buy-goldbacks
Lots of fake gold coins in the market. No so, with goldbacks.
BRICS nations are already turning to these.
As for coins and bars, etc., you have to sell them to a broker for money.
CryptoCurrency is IFFY and some a blatant trap. BC / BitCoin is one of those IN MY HUMBLE OPINION. See Eye Hey! Know the history and don't believe what they tell you about it, anyway! Buy items that you can readily barter with and make your own wampum!!! Make certain your community (not necessarily government) is on board<<<<!!!
