Bitcoin is first digital currency it's mean that we can not touch the bitcoin like usd or inr but we use this to do many transaction over the internet many of sites is legally using the bitcoin as a transaction currency.
Satoshi nakamoto Invented the bitcoin as a digital currency in 2009. In January 2009, the bitcoin network came into existence with the release of the first open source bitcoin client and the issuance of the first bitcoins,[12][15][16][17] with Satoshi Nakamoto mining the first block of bitcoins ever (known as the genesis block), which had a reward of 50 bitcoins. Embedded in the coinbase of this block was the text.
One of the first supporters, adopters, contributor to bitcoin and receiver of the first bitcoin transaction was programmer Hal Finney. Finney downloaded the bitcoin software the day it was released, and received 10 bitcoins from Nakamoto in the world's first bitcoin transaction.
In 2017 the amount rate of 1 Bitcoin is increase upto 5 times after increasing the bitcoin rates there are some problems faced by users to do transactions after that the bitcoin company uses hard fork to split the bitcoin into two parts.
