Big picture

Summary by year

Time period Development summary More details
1976–2002 Background research The key advances in public-key cryptography, proof-of-work systems, etc., are made during this period.
2003–2007 Lull? (This is the period during which anyone with sufficient knowledge and insight could have invented Bitcoin, but nobody did.)
2008–2010 Early days of Bitcoin Satoshi Nakamoto's white paper is published, the Bitcoin client is released, and some "firsts" take place, like the first trade for fiat money and first trade for a good. Satoshi Nakamoto is still around during this period.
2011–2012 Continued development Satoshi Nakamoto disappears, but Bitcoin growth continues. Silk Road, BitPay, and Coinbase all launch during this period.
2013 First crash The price of one Bitcoin reaches US$1,000 for the first time. Shortly after, the price quickly begins to decline, plummetting to around U$300. It would take more than two years before the price reached $1,000 again.[1]
2014–2016 Temporal stall In January 2014, Mt.Gox, the world’s largest Bitcoin exchange, goes offline, and the owners lose 850,000 Bitcoins.[1] This is considered the biggest Bitcoin heist in history. Quickly the Bitcoin price falls below $1,000 around the time, and would struggle below the key level for a few years.[2]
2017 Mainstream popularity Bitcoin sees a roughly 20-fold rise since the beginning of the year, growing also exponentially in popularity. Throughout 2017, Bitcoin value would grow from US$900 to almost US$20,000.
2018 Bitcoin crash In January, the Great crypto crash occurs. After an unprecedented boom in 2017, the price of Bitcoin falls by about 65 percent during the month from 6 January to 6 February. In late March, Facebook, Google, and Twitter ban advertisements for initial coin offerings (ICO) and token sales.[3] The price steadily drops all year.[2] By November 15, Bitcoin's market capitalization falls below US$100 billion for the first time since October 2017 and the price of Bitcoin falls to $5,500.[4][5]
2019 Resurgence Bitcoin sees a new resurgence in price and volume, rising to around US$10,000. As of the end of 2019, the price of one Bitcoin is of around US$7,250.
