Back in 2008, bitcoin.org was registered. In November of the same year, a white paper was published in a cryptography mailing list entitled, Bitcoin: A Peer-to-Peer Electronic Cash System under the pseudonym, Satoshi Nakamoto. The following year (2009), Bitcoin was introduced in the market. Back then, it did not have any significant value. It was the people themselves who decided how much it would worth. There was this famous transaction where two pizzas were bought for 10,000 bitcoins. As of the first week of January 2018, the price of 1 bitcoin is worth around $15,000 USD.
