> On the other hand, if he did the cash drops with Bitcoin instead, ... Actually, the most recent episode of "Aktenzeichen XY ... ungelöst"[0] (a German TV show that is basically the same as "Crimewatch" or "America's Most Wanted", but predating both of them) mentioned such a case [1]. Some guy in Berlin sent bombs via mail back in 2017/2018 and demanded a ransom paid in Bitcoin. They didn't explain the details, but apparently police did trace a transaction to that wallet back to some Bitcoin vending machine and got a nice picture from there.
