Well, that's what it is today. But if BTC has no fundamental value, you might argue the price fluctuations are the price-discovery function of markets screaming "there is no correct price because there is no actual value", or something like that.
All other fiat currencies have some fundamental value. In the past they were backed by gold. Most common today, you have to pay your taxes using them, which means for example everybody who owes US taxes needs USD.

That makes no sense. If the market were really 'screaming there is no actual value', the price would be around $0, not $14K.
It makes sense to me in a divide-by-zero sort of way. I'm not saying the market confidently believes bitcoin has no value. But such wild fluctuations might suggest that even after five years, the price discovery function still has no idea what bitcoin is worth. Now what does that mean? We can only speculate, of course. But to me I wonder if 1) there is no identified fundamental value today and 2) no one knows what the fundamental value will turn out to be
