Well there are several from the 'get rich quick scheme' aspect vs lead into gold aspects to the fact it is trying to get what they want by properties of analogy. That they can turn processing power into the new gold. Then there is the literal magical thinking like the sun and gold must be connected because of the same color therefor if we create a scarce currency it will be a useful commodity and gold shares properties of the sun, also the sun's rays created gold. Alchemists pursue the same goal obsessively trying to get what they want despite the mechanism for it just plain /not being there/. Similarly Cryptocurrency even if it perfect in security and privacy would run into interchange issues. You would need teleportation to bring commerce beyond government control.

Gold is a very apt comparison given the gold-bug rhetoric they were in pushing deflationary currency despite its history of failures resulting in fiat currency. The gold standard resulted in /many/ wars for the sake of gold just so that they wouldn't have their economy size capped by lack of currency - leading to considerable loss of /real/ value and massive suffering. Ironically having too much gold also created inflation issue. Having currency that can inflate with the economy instead of something else arbitrary is what the strength of fiat currency is.
