A type of Bitcoin wallet that works as a bearer instrument that can be used to store bitcoins in a physical novelty item.
A physical bitcoin holds the coin's public address and a hidden private key. The intention with a physical bitcoin is that the value of the coin has not and cannot be spent as long as the private key remains hidden.
The security of physical bitcoins depends on the tamper-evident seal, and is usually not very strong. At hackathons and bitcoin meetups it has been demonstrated that the tamper-evident seal can be carefully replaced after obtaining the private key.
