The biggest scam is the right to mint coins. Any country can use the right to mint coins to reap profits, but the general trend is irreversible.
Every time a large amount of money is released, there is prosperity.

The exchange of real gold and silver for paper money (paper money is too ugly, it was called cash before, and now it is called digital currency) must start with Cixi, who was unable to support it and ran away with silver.
Gold has never had the largest market value before the US dollar. At that time, silver was in hard circulation, and now it has been exchanged for gold.
With the changes of the times, when the powerful no longer have the most gold, Bitcoin can be established as an anchor.
But every contract ends with a pin-out and liquidation, and those with large funds can only hold spot and wait for the general trend.
