Just off the phone with a close friend who's octogenarian mother was scammed into withdrawing tens of thousands of dollars in cash from her bank, then buying and sending Bitcoin to the scammers. He was hoping I could help. Beyond basic on-chain analysis, of course, I can't.

But what stuck with me is this: if a large, regional bank doesn't flag and prevent an elderly person from taking thousands of dollars in cash out over a few days from multiple local branches, what even is the point of them? Incredible.
