Cryptocurrency began with Bitcoin's introduction in October 2008, when a person or group using the name Satoshi Nakamoto published a whitepaper describing a "peer-to-peer electronic cash system." The actual Bitcoin network launched on January 3, 2009, with the creation of the "genesis block." Earlier digital currency attempts existed since the late 1980s, including DigiCash and Bit Gold. The technology would soon revolutionize global finance.
Though digital money existed in various forms since the late 1980s, cryptocurrency as it is understood today began with Bitcoin's introduction in 2008. On October 31 of that year, a person or group using the name Satoshi Nakamoto published a whitepaper outlining a "peer-to-peer electronic cash system." This document explained how a digital currency could work without needing banks or other middlemen to verify transactions. The paper introduced blockchain technology and solved the "double-spending problem" that had limited earlier digital cash attempts.
Before Bitcoin, several important projects laid the groundwork for cryptocurrency. In 1989, cryptographer David Chaum created DigiCash, an early form of electronic money. Other notable precursors included Adam Back's HashCash (1997), Wei Dai's B-money (1998), and Nick Szabo's Bit Gold (1998). E-gold, founded in 1996, operated until 2009 as a digital currency backed by physical gold.
The actual Bitcoin network launched on January 3, 2009, when Nakamoto mined what's known as the "genesis block." Nine days later, on January 12, the first Bitcoin transaction took place. The software behind Bitcoin was released as open-source code in 2009, allowing anyone to examine or modify it. Bitcoin reached a significant milestone in May 2010 with its first real-world purchase – two pizzas bought for 10,000 bitcoin. This purchase, now commemorated as Bitcoin Pizza Day, became a historic moment illustrating Bitcoin's potential as a medium of exchange. By February 2011, Bitcoin achieved parity with the US dollar for the first time.
Bitcoin's success inspired the creation of alternative cryptocurrencies, commonly called "altcoins." Namecoin appeared in April 2011, followed by Litecoin in October of the same year. Peercoin launched in August 2012, while Dogecoin and Dash debuted in December 2013 and January 2014 respectively. Each of these coins offered different features or improvements to Bitcoin's original design. These altcoins emerged as part of a broader cryptocurrency evolution that sought to address Bitcoin's technological limitations.
As cryptocurrencies grew in popularity, exchanges emerged to help people buy, sell, and trade these digital assets. Bitcoin Market, established in 2010, was among the earliest. Mt. Gox launched in July 2010 and quickly became the largest exchange before its collapse in 2014. Other early exchanges included Bitstamp and Kraken (both founded in 2011) and Coinbase (2012).
Government responses to cryptocurrency varied widely. In 2013, the US Financial Crimes Enforcement Network (FinCEN) issued its first guidance on virtual currencies, while China banned financial institutions from handling Bitcoin transactions. New York introduced the BitLicense regulatory framework in 2015. Japan recognized Bitcoin as a legal payment method in 2017, and in 2018, the US Securities and Exchange Commission declared that Bitcoin and Ethereum were not securities.
Mainstream adoption accelerated when companies like Overstock.com and Microsoft began accepting Bitcoin in 2014. The 2017 launch of Bitcoin futures trading on major exchanges, PayPal's 2020 cryptocurrency integration, and Tesla's $1.5 billion Bitcoin investment in 2021 further legitimized the technology for everyday users. Bitcoin reached an unprecedented milestone in December 2024 with a record-breaking value of over $103,000 per coin.
