As a crypto analyst with five years in DeFi and NFT markets, I’ve seen too many 'pig butchering' scams unfold — but this case is different. Michael Zidell lost $20M to a fake NFT investment orchestrated on Facebook, and now he’s suing Citigroup for failing to flag suspicious transactions. The bank accepted nearly $4M into a corporate account tied to the fraud. This isn’t just about greed — it’s about systemic failure in anti-money laundering (AML) protocols. If banks don’t act, even the most cautious investors are at risk.
