You're making a category error. The subject is stocks on the blockchain, not currencies. Blockchain does not equal currencies only. NFTs are digital tokens of ownership that can be tied to securities for example. An NFT based stock system would be devoid of fraud and manipulation like naked shorting, synthetic shares, PFOF, FTDs and the need for regulatory bodies.

No brokers. Trades cost pennies. Power to the players.
