EDIT As pointed out in this thread, that's not a bitcoin address. That's just a GPG key fingerprint. Nothing to do with bitcoin itself. Terribly sorry for the foobar. The original post: > It's a bitcoin address, used for both sending and receiving. If you want to trade with a person, you enter that address as receiver's address in a transaction. Nb., each bitcoin user can freely generate several addresses to protect privacy; up to and including using one-off addresses (i.e., address for just one transaction).
