Where did bitcoin come from?
In October 2008, person or group using the pseudonym Satoshi Nakamoto posted a paper on a cryptography mailing list on bitcoin and how the cryptocurrency could work. In January 2009, the first bitcoin was mined and the software was released. The inventor of bitcoin was rewarded with all bitcoin mined in the currency's first ten days of existence, all of which is still unspent to this day. The blockchain shows that that there are still about one million bitcoins in Nakamoto's known wallet addresses, making the inventor worth a cool $7.5 billion.
There is still much speculation about the true identity of Satoshi Nakamoto, most of which is focused on a group of cypherpunks, a term used for cryptography enthusiasts and experts.
