About four million Bitcoins appear to be lost, lurking as unredeemable fortunes on the blockchain. Can rightful owners or heirs ever reclaim these now tens of billions of dollars? Can digital treasure hunters willing to wander into sketchy legal territory do the same?

Learning Objectives: 1: Show how “lost” cryptocurrencies are being recovered. 2: Get attendees excited (worried?) about potential new treasure hunting on the horizon. 3: Cover the quantum threat to BTC and other blockchains.
