Currencies don´t work that way. If a majority believes in them, they are working. And obviously a majority does, otherwise BTC would have collapsed in the meantime, like so many other cryptocurrencies. The "token themselves" have no more value than the individual US dollars. The trust in the system builds the value. And this particular system prevents an easy de-evaluation which is since centuries applied to fiat money by printing money as wished directed by a small group of influencers.
