Bitcoin (₿) is a coin that is a form of electronic currency. This is a decentralized currency which has no central bank or single administrator that can transmit from user-to-user to peer-to-peer bitcoin network without the need for intermediaries.
The transactions are analyzed with the help of a network of nodes through cryptography and recorded on a public distributed ledger called blockchain.
Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto
And released as open-source software in 2009.
Bitcoins were created as a reward for the process known as mining. It can be replaced with other currencies.
products, and services. Research carried out by the University of Cambridge estimates in the year 2017, with 2.9 to 5.8 million unique users using cryptocurrency wallets, most of them using bitcoin.
Bitcoin has been criticized for its use in illegal transactions, the consumption of electricity, volatile prices, theft of exchanges, and the possibility that bitcoin is an economic bubble.

Bitcoin & History
The domain name "bitcoin.org" was registered on August 18, 2008.
On October 31, 2008, a link to a paper created by Satoshi Nakamoto with the title Bitcoin: A Peer-to-Peer Electronic Cash System.
was posted to a cryptography mailing list.
Nakamoto launched bitcoin software as open-source code and released it in January 2009.
Nakamoto's identity remains a mystery.
In January 2009, the bitcoin network was created by Nakamoto's company the first block of the chain, known as the genesis block.
This block is embedded in the coinbase with the following text:
The Times 03 / Jan / 2009 Chancellor on brink of second bailout for banks." This record is explained as both a timestamp and a comment on the cause of the fractional-reserve banking vulnerability.
The receiver of the first bitcoin transaction was cypherpunk Hal Finney, who created the first reusable proof-of-work system (RPOW) in 2004.
Finney downloaded bitcoin software on the date of its release, and on January 12, 2009 received ten bitcoins from Nakamoto.
Some of the early supporters of cypherpunk were creators of bitcoin predecessors: Wei Dai, the creator of b-money, and Nick Szabo, the creator of bit gold.
In 2010, the first known commercial transaction using bitcoin occurred when programmer Laszlo Hanyecz bought two Papa John's pizza worth 10,000 bitcoins.
Nakamoto is estimated to have mined one million bitcoins.
before his disappearance in 2010, holding the network alert keys and control of the code repository beyond Gavin Andresen. Andresen later became the lead developer at the Bitcoin Foundation.
Andresen sought decentralized control. That left a chance of controversy over the development of bitcoin's future development.
