IntroductionA digital or virtual currency that uses peer-to-peer technology to facilitate instant payments. Bitcoin is a type of alternative currency known as cryptocurrency and uses cryptography for security, making it difficult to counterfeit. Bitcoin issuance and transactions are carried out collectively by the network, without any central authority. The total number of Bitcoins that will be issued is limited to 21 million to ensure they are not devalued with unlimited supply. They are divisible up to 8 decimal places; Fractions of Bitcoin are called satoshis. Users store their Bitcoin in a digital wallet, while transactions are verified by a digital signature known as a public encryption key. History“The term Bitcoin was proposed in a white paper by Satoshi Nakamoto in 2008. On September 18, 2008, the domain bitcoin.org was purchased and subsequently registered and published the first Bitcoin client in 2009. On July 12, 2010, the the first transaction with 10,000 bitcoins for two pizzas and then, on July 17, MtGox, the currently largest Bitcoin exchange, went online. On October 17, 2010, the bitcoin-otc channel on the Freenode IRC was activated to allow global currency exchange chat. On June 11, 2010, bitcoin volume was already at $1 million, and on February 9, 2011, Bitcoin reached parity with $1. American dollars. After an April article in TIME magazine and an article in early June, the price rose to around $30. Within days, the price plummeted and several thousand online accounts and bitcoins were stolen. In the first four months of 2013, the stock price multiplied, and on April 1 of that year, Bitcoin surpassed the $100 mark on MtGox. Today the pizza order is worth more than 1 million euros.......half of the card......rency will take its place in the future.ConclusionsFactsThe first Bitcoin transaction was performed on 01.12.2009. It takes 5 years for a single bitcoin to go from $0 to $1,000.20000+ number of computers working to mine new bitcoins. There will be 21 million bitcoins that will be available.

In a separate case, bitcoin escrow accounts belonging to customers on a different black market were hacked in early 2014.
