@codinghorror Crypto has a lot of good ideas: decentralized consensus, decentralized identity, control over information, non-fungible tokens (and I don't mean JPEGs, but provably transferring a digital entity from one person to another in a decentralized way), and of course, amazing potential for privacy with zkSnark transactions.
I'm not ready to throw out all of crypto because grifters started abusing it, any more than I'd throw out email or the internet in general (for the same reason).
