Cryptobro argument "If NFTs are so wasteful, then why have VISA and Mastercard been researching crypto for decades".... Wow, really? You need to ask why credit card companies are researching a scam? Golly, I wonder why companies involved in predatory lending, who are widely known to target the financially ignorant, would have some interest in blockchain... It just boggles my mind. Surely companies with such upright reputations wouldn't want to be involved in something that's about making money in unethical ways, right?
