The plaintiff who bought a truck online from a scammer sent money to a bank account without even visiting the truck to know that it's real.
The bank account was owned by the defendant, a bitcoin over-the-counter trader, who advertised a service of selling people bitcoin who paid to his bank account.
If you haven't caught it yet, the scammer who was selling the fake truck was also buying the bitcoin from the defendant. So he managed to bait the plaintiff into buying something that didn't exist, and paying into the bitcoin trader's account, while telling the defendant that he was sending that money to buy bitcoin. The defendant then gave the bitcoin to the customer, who scammed off with the money.
Both of the individuals are victims of a man-in-the-middle attack, which the defendant correctly stated. However, the technical knowledge level of the audience and Ms. Judy herself is too low to appreciate it. Irony ensues. Video below.
