It's worth noting that fungi aren't fungible in the way that blockchain-based cryptocurrencies are, which is a real misfeature.

For example, you can't leverage fungi to build a blockchain-based English language dictionary and then leverage that to rename "fungi" to avoid confusion for blockchain investors. You can do that with blockchain, and should.

Also IIRC market cap is smaller.

tldr; the fact that "legacy fiat funguses" are inferior to blockchain is proved by leveraging trustless transactions of the blockchain.
