Cryptocurrency has been yet another excellent demonstration of greater fool theory in action.
I remember in one nerdy group chat I was in someone joined and asked if anyone was into crypto. I asked "Cryptography, or cryptocurrency?"
"No, cryptozoology. I'm searching for the Loch Chain Monster."

Agreed, but Lock Chain doesn't really work.
