>Ok then, how do you call a currency that is not tied to any existing market good. I'd like to know the name of the thing, if it's not fiat.
In that case, that currency is the market good. This includes Bitcoin, which is a market good. It may be a market good that you personally think is useless, it may be a market good that you personally wouldn't pay for, but it still is a market good.
>It does not represent any existing things in any market's demand, it is above them
Again, BTC is the thing in demand. There exists a commodity market for bitcoin.
>So could do a commodity based currency. Probably a lot better than this weird abomination.
Yeah, but the fact that commodity money can do something doesn't discount the fact that crypto can do this too. Whether it's better or not is a matter of preference and opinion. I'm actually a fan of gold over crypto myself, but I can recognize that crypto has certain features (namely the blockchain and its self-regulating recordkeeping) that might make it more desirable to certain people.
>Gold would be less useful but bitcoin would not be useful at all, still.
I think you missed the point I was making. Whether or not you consider something "useful" doesn't change the fact that these things have value. There's no such thing as "use-value" in the market–people value things because of their own subjective preferences, not because of any kind of use value. Let's take gold, for instance. Where's the use value in gold? It's shiny, and that's fucking it. It's shiny and stays shiny for a long time. Modern chemicals let us make things similarly shiny to gold with greater durability, and for a lot cheaper too, yet gold is still heavily in demand. Why? Because people subjectively value gold for almost arbitrary reasons, and so the price remains high. Or consider how in demand Top40 pop music is despite how derivative and objectively shite the vast majority of titles are–even though it makes no sense, people value this drivel and are willing to pay money for it for their own arcane reasons, and so it remains valuable.
