"The LinkedIn 'Web3 Expert'"

This is a species very different from the Twitter Degen. They inhabit LinkedIn. They post long, "professional" writings full of platitudes about the "Future of the Metaverse" or "Enterprise Blockchain Synergy". However, if you check their wallets, they have almost never made an on-chain transaction. Their knowledge is purely theoretical from reading news articles, not from field practice. They sell the image of an expert to be invited as a seminar speaker, not to seek market profits.
