You said earlier that "Currencies are enforced and controlled by central, powerful authorities". There is no central authority for gold yet it has been a currency for thousands of years. You seem to accept the special status of gold by implying that a cryptocurrency could be effective as a currency if it was backed by gold. So my question is what makes gold so special? Why can't the current design of cryptocurrencies be just like gold, only more convenient?
I see, the correct version would be: Fiat currencies [...].
> My point is that gold has similar properties to Bitcoin.
I agree with your point.
> Why can't the current design of cryptocurrencies be just like gold, only more convenient?
Cryptocurrencies are a lot like gold. But as you said, gold is around for centuries. Can you bet 10 million USD that bitcoin will be around next year?
I'll bite the bullet though:
> Hmm... so gold cannot be a currency?
Everything can be a currency. Ascorbic acid could be a currency in the future if the humankind moves to planets where Citreae are hard to find.
If I'm not mistaken, the topic was about the effectiveness of bitcoin as a currency.
