As many of us obsess over sordid details of fraud in the crypto world, let’s not forget about good old filth with tried-and-true cash. I’m thinking of the suitcases stuffed with €1.5 million ($2.3 million) – much of it in €50 bills – that Belgian police found this week as they raided some apartments and offices in Brussels.

The main hoard allegedly belonged to Eva Kaili, a Greek member of the European Parliament and, until this week, its vice president. She supposedly got the money from Qatar in return for saying nice things about the emirate and helping its efforts to lift visa requirements.
