What does $450,312,500, the sum paid at Christie’s last week for Leonardo da Vinci’s circa-1500 painting Salvator Mundi (the “Savior of the World”), look like? How about 55,000 Bitcoins at today’s exchange rate (if you could actually swap the things). Fake money for a dubious da Vinci—that would be fitting. But kidding aside, after bidding breached $250 million, the disputed painting began to resemble art. So goes human nature.
