Why is Bitcoin different than gold though? Is gold also a Ponzi scheme?
The value of gold is supported by huge militaries all around the world, including the US military. Just like fiat currency, it derives its value in part from the large group of people with guns willing to commit violence to support its value. Bitcoin doesn't have an army of people willing to commit violence to support its value. At least not yet.
Back in the 60s the gold trade was highly regulated. That's why the plot of Goldfinger doesn't really make any sense from a moderns perspective. It seemed quaint even to me as a teenager in the 80s. Nowadays gold is just posh bitcoin.
