BitCoin

Definition of 'Bitcoin':

A digital or virtual currency that uses peer-to-peer technology to facilitate instant payments. Bitcoin is a type of alternative currency known as a cryptocurrency, which uses cryptography for security, making it difficult to counterfeit. Bitcoin issuance and transactions are carried out collectively by the network, with no central authority. The total number of Bitcoins that will be issued is capped at 21 million to ensure they are not devalued by limitless supply. They are divisible to eight decimal places; Bitcoin fractions are called satoshis. Users store their Bitcoins in a digital wallet, while transactions are verified by a digital signature known as a public-encryption key.

Investopedia explains 'Bitcoin'

The first Bitcoin specification and proof-of-concept was published in 2009 by an individual or individuals under the pseudonym Satoshi Nakamoto. Satoshi left the project toward the end of 2010, leaving the motivation behind setting up Bitcoin an enduring mystery.

Bitcoins are created through a “mining” process that involves complex number crunching by the computers in this network; this process currently creates 25 Bitcoins every 10 minutes. The limit of 21 million is expected to be reached in the year 2140, after which the total number of Bitcoins will remain unchanged.

A basic premise underpinning the Bitcoin is that because it is decentralized and not issued by government, it is supposedly free from interference and manipulation, in stark contrast to the world’s fiat currencies.
