I mean it is very very useful for specific purposes, like purchasing, uh, certain substances in certain, uh... unregulated online marketplaces.

As far as being a currency for other purposes goes though, I think it is incredibly unfit for purpose. And as far as being an investment vehicle goes it's essentially a ponzi scheme.

Gold is useful in that it always remains gold but that's the extent of it.

Wouldn't say terrible. Just volatile and with a specific use cas. But incaseyour currency loses value you still have some wealth wich you can use for financial interactions (assuming you still have access to it)
