Bitcoin works perfectly as a medium of exchange though, especially with Lightning network.

Which makes it very useful in my view. Gold was dead throughout the 80s, 90s and early 2000s. Why? Because gold is rapidly replaced by a scarce store of value like the high interest rate money of the 80s.

I think a bit of physical gold is a good investment, but a lot of gold is really more wishful thinking than anything else.

We will never be able to know how much gold governments have.

For me Bitcoin is the currency of freedom, not gold. But to each it's own of course. :)
