Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto[9] and released as open-source software in 2009.[10] Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[11] products, and services. Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[12]
As bitcoin has matured as a cryptocurrency there has been more companies warming to the idea of using various bitcoin exchange facilities to gain exposure to the volatile bitcoin price while a few websites such as reddit WordPress and overstock have begun accepting bitcoins, most major retailers have yet to take the plunge into the cryptoverse whils other pioneers have decided to create their own bitcoin forks and have listed new projects on other cryptocurrency exchanges.
As the market valuation of the total stock of bitcoins approached US$1 billion, some commentators called bitcoin prices a bubble.[145][146][147] In early April 2013, the price per bitcoin dropped from $266 to around $50 and then rose to around $100. Over two weeks starting late June 2013 the price dropped steadily to $70. The price began to recover, peaking once again on 1 October at $140. On 2 October, The Silk Road was seized by the FBI. This seizure caused a flash crash to $110. The price quickly rebounded, returning to $200 several weeks later.[148] The latest run went from $200 on 3 November to $900 on 18 November.[149] Bitcoin passed US$1,000 on 28 November 2013 at Mt. Gox.
Bitcoin paints a future that is drastically different from the fiat-based world today. This is either exciting or unsettling for the vast majority. Equip yourself with the best possible resources. Become active in communities that further explore not only the technical applications of Bitcoin and other cryptos, but with their overall potential to disrupt virtually every market. Brace yourselves. Cryptos are coming.
Nigel Dodd argues in The Social Life of Bitcoin that the essence of the bitcoin ideology is to remove money from social, as well as governmental, control.[124] Dodd quotes a YouTube video, with Roger Ver, Jeff Berwick, Charlie Shrem, Andreas Antonopoulos, Gavin Wood, Trace Meyer and other proponents of bitcoin reading The Declaration of Bitcoin's Independence. The declaration includes a message of crypto-anarchism with the words: "Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian."[124][123]

Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs. While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.


In 2013 and 2014, the European Banking Authority[144] and the Financial Industry Regulatory Authority (FINRA), a United States self-regulatory organization,[145] warned that investing in bitcoins carries significant risks. Forbes named bitcoin the best investment of 2013.[146] In 2014, Bloomberg named bitcoin one of its worst investments of the year.[147] In 2015, bitcoin topped Bloomberg's currency tables.[148]
Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by trading it. The price of bitcoin skyrocketed into the thousands in 2017.
Bitcoin is an increasingly popular cryptocurrency that utilizes blockchain technology to facilitate transactions. Basically, a user obtains a Bitcoin wallet that can be used for storing bitcoins and both sending and receiving of payments. The blockchain technology used by Bitcoin is really just a shared public ledger that is used by the entire public network. The technology used is secured through cryptography, a branch of mathematics that provides a highly secure means of facilitating and recording transactions on the network.
In its October 2012 study, Virtual currency schemes, the European Central Bank concluded that the growth of virtual currencies will continue, and, given the currencies' inherent price instability, lack of close regulation, and risk of illegal uses by anonymous users, the Bank warned that periodic examination of developments would be necessary to reassess risks.[179]
In October 2013, the FBI seized roughly 26,000 BTC from website Silk Road during the arrest of alleged owner Ross William Ulbricht.[78][79][80] Two companies, Robocoin and Bitcoiniacs launched the world's first bitcoin ATM on 29 October 2013 in Vancouver, BC, Canada, allowing clients to sell or purchase bitcoin currency at a downtown coffee shop.[81][82][83] Chinese internet giant Baidu had allowed clients of website security services to pay with bitcoins.[84]
Bitcoin is one of the first digital currencies to use peer-to-peer technology to facilitate instant payments. The independent individuals and companies who own the governing computing power and participate in the Bitcoin network, also known as "miners," are motivated by rewards (the release of new bitcoin) and transaction fees paid in bitcoin. These miners can be thought of as the decentralized authority enforcing the credibility of the Bitcoin network. New bitcoin is being released to the miners at a fixed, but periodically declining rate, such that the total supply of bitcoins approaches 21 million. One bitcoin is divisible to eight decimal places (100 millionth of one bitcoin), and this smallest unit is referred to as a Satoshi. If necessary, and if the participating miners accept the change, Bitcoin could eventually be made divisible to even more decimal places.

In December 2013, Overstock.com[87] announced plans to accept bitcoin in the second half of 2014. On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins.[88] After the announcement, the value of bitcoins dropped,[89] and Baidu no longer accepted bitcoins for certain services.[90] Buying real-world goods with any virtual currency had been illegal in China since at least 2009.[91]
By December, Bitcoin was on track to hit its all-time high thanks to a dramatic and steady increase in price. On Dec. 17, 2017, it reached $19,783.21, the all-time high that has yet to be broken. Unfortunately, that high was followed by a drop of about 30 percent, with a market correction that brought it down to under $11,000. The price did recover, reaching $16,000 again on Dec. 27.
No one knows. Not conclusively, at any rate. Satoshi Nakamoto is the name associated with the person or group of people who released the original Bitcoin white paper in 2008 and worked on the original Bitcoin software that was released in 2009. The Bitcoin protocol requires users to enter a birthday upon signup, and we know that an individual named Satoshi Nakamoto registered and put down April 5 as a birth date. And that's about it.
