Bitcoin is the world's first electronic currency coin, the most popular currency medium of the day...
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,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.
Bitcoin is the world's first cryptocurrency, a form of electronic cash sent peer-to-peer without the need for a financial intermediary. It is the first decentralized digital currency: the system works without a central bank or single administrator.
