Thanks to the pointer from Ben Evans for this story. I know this sounds strange, but I really enjoyed reading this US court filing. It has a great description of blockchain, NFTs, and the kind of scams that they are being used for. Worth taking a few minutes to go through it.
As Ben says:
The US arrested and charged two twenty-year-olds for launching a crypto project, making promises, collecting $1.1m and then disappearing. Noteworthy because the police found that existing laws were adequate and, more importantly, the crypto transactions were perfectly feasible to track.
