Coin [Bitcoin]

Definition of a coin: chain of digital signatures.
A bitcoin is a number that is associated with a Bitcoin address.

Creation of coins

The first transaction in a block is special: it starts a new coin which is owned by the creator of the block.

Fungibility

Bitcoins are not fungible.
This is because each Bitcoin has a history and is traceable.
It might happen, for example, that someone (a coin collecter) values a bitcoin that originated in the genesis block higher than any other bitcoin.

No Bitcoin per se

There is no such thing as a «bitcoin» per se. There are only unspent transaction outputs which are referred to as coins.
