A similar useage is common, though not universal, in the Bitcoin world.' http://www.michaelnielsen.org/ddi/how-the-bitcoin-protocol-actually-works/ And: "There is no uniform convention for bitcoin capitalization. Some sources use Bitcoin, capitalized, to refer to the technology and network and bitcoin, lowercase, to refer to the unit of account.[25] The Wall Street Journal,[26] The Chronicle of Higher Education,[27] and the Oxford English Dictionary[24] advocate use of lowercase bitcoin in all cases, which this article follows." https://en.wikipedia.org/wiki/Bitcoin#Etymology_and_orthography

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] 2014 is characterized by mainstream investors discovering their appetite for bitcoin startups.[3]
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.[4] 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.[5][6]
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.
2020–2021 New heights Bitcoin valuation surpasses the 2017 bubble highest value. Increasing institutional adoption is experienced as the first real signs banks, money managers, insurance firms and companies start to embrace fast-growing markets for cryptocurrencies and digital assets.[7]

Summary by country

Key country Summary
United States The United States is home to most of the world's largest Bitcoin companies, as well as most crypto endeavors and activities.[8][9] There is a large number of exchanges, trading platforms, funds, crypto mining facilities, and blockchain-oriented projects.[8] As of February 2019, This country leads with over 2,625 nodes, followed by Germany and France with 2016 and 698 respectively.[10]
China As of June 2018, financial institutions are not allowed to facilitate Bitcoin transactions.[11] The country leads in digital trading, and its exchanges have one of the biggest volumes of Bitcoin being traded on a daily basis.[8]
Japan As of 2020, Japan is one of the few countries that recognize cryptocurrencies as a legitimate means of payment. The country has one of the most effective regulatory environments in the world related to blockchain technology and virtual currencies. After the United States Dollar, Japan is also the country with the second-largest trading volume against Bitcoin around the world.[8]
South Korea South Korea accounts for almost 10% of all the Bitcoin traded around the world, after the United States Dollar and the Japanese Yen. The country hosts a large amount of exchanges and crypto businesses and there is a big interest in trading and using cryptocurrencies among the population.[8]
Switzerland Switzerland aims to become a cryptocurrency and blockchain hub. Local regulators have a very open mind towards digital assets.[8] It is possible to pay taxes with Bitcoin in some districts of the country. However, there is currently no form of "state-backed" cryptocurrency.[12]
