NFTs were the perfect technology to identify people who didn’t understand crypto. The only reason Bitcoin et al. even almost work is that nearly anything can be a medium of exchange… so long as it’s fungible. Which is the F theses Ts are N.
But if all you saw was numbers going up, and you don’t know what a Ponzi scheme is, yeah sure it makes total sense to buy a genuine commemorative plate of the Brooklyn Bridge. Why’s everyone on your case? It must be worth money! It’s (a receipt for a link to a picture of) the Brooklyn Bridge!
Fanbros compare stocks, but stocks are slices of a real company. You control one-zillionth of an actual business. If you own enough, that company will do what you say, because you are literally their boss. No amount of “authentic” Brooklyn Bridge tokens will ever mean you get the bridge.
Everything signifying that the exchange was worth your money is a fiction created by the people who took it. That’s how scams work.
