If “Bitcoin is a virtual currency,” why don’t some people consider “Pendrive” (a physical device that stores public-private keys to manage the coin of blockchain) as “physical value call”?
For example, suppose Bob provides ALICE with a pen drive with one bitcoin. Alice exchanges his favorite programming book called “JavaScript” for 1 bitcoin included in Pendrive.
how?
Alice(book) -> Bob (pendrive)
Bob(pendrive) -> Alice (book)
Is it considered a valid transaction (PENDRIVE-> BOOK) even if it is not in the block chain? In this virtual scenario, the blockchain was not performed directly, but was there a valid deal?
