People
Utah-based Mike Caldwell started producing Casascius physical bitcoins — collectible brass, silver, and gold coins with a private key concealed under a holographic sticker. Each coin's denomination (1 BTC, 25 BTC, 100 BTC, and more) was funded with real on-chain bitcoin. They became iconic artifacts of early Bitcoin culture and one of the first ways to gift or display BTC in the physical world.
