Why Gold and Silver
Gold is Money. Everything else is debt.
J P Morgan
The quotation above is attributed to J P Morgan, the famous banker, but is not exactly what he said. Although it is near enough.
What he actually said was -
... it [credit] is not the money itself. Money is gold, and nothing else.
So, what is gold ? And what is silver ?
Gold is used in the manufacture of jewelry and in electronics. Silver is used in electronics, photograppy, the manufacture of solar panels and even in medicines.
But the real value of gold and silver are as stores of value.
For 1000s of years gold and silver have been considered as stores of value and as a means of barter. In other words - MONEY.
