Bitcoin is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries.
Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin is unique in that there are a finite number of them: 21 million.
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.
[17] As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.[18].
Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.
NOTE: WARNING: Please be aware that the cheapest price of Bitcoin can be highly volatile, and prices can change rapidly and unpredictably. Investing in Bitcoin carries a high level of risk and you should only invest what you are willing to lose. Please do your own research before investing in any cryptocurrency, and never invest more than you can afford to lose.

The first bitcoin transaction took place on January 3, 2009, when Nakamoto sent 10 bitcoins to an early adopter of the currency named Hal Finney. Nakamoto subsequently disappeared from any involvement in bitcoin. Andresen later became lead developer at the Bitcoin Foundation.[20][21] Adam Back developed hashcash, a proof-of-work scheme for spam control.
The first proposals for distributed digital scarcity based cryptocurrencies were Wei Dai’s b-money[22] and Nick Szabo’s bit gold.[23] Hal Finney developed reusable proof of work (RPOW) using hashcash as its proof of work algorithm.[24].
In 1996, researcher Nick Szabo described “bit gold”, which similar to bitcoin.[25] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published.
A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.

Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The network is peer-to-peer and transactions take place between users directly, without an intermediary.
Bitcoin mining is the process of creating new bitcoins by solving complex mathematical puzzles. Bitcoin miners are rewarded with bitcoins for their efforts. The process of mining bitcoins is very resource-intensive, and requires a lot of electricity to power the computers that do the mining.
It is a common misconception that Bitcoin is expensive. While it is true that the price of Bitcoin has seen some volatile swings over the years, it is still very affordable for most people. In fact, there are many countries where you can buy Bitcoin for less than $10 USD.
The cost of mining Bitcoin can vary quite a bit depending on where in the world you are located. For example, in countries with cheap electricity, like China or Venezuela, the cost of mining Bitcoin is much lower than in places like the United States or Canada. There are a few factors that go into determining the cost of mining Bitcoin.
