Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency. The network is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by Satoshi Nakamoto. Earlier in India, all the cryptocurrency was banned. But, in 2020 the government of India/ RBI has made it legal and I think it is one of the best entities where one can invest and also I have a feeling that buying bitcoin in India will become very normal and this will boom the market of Bitcoins.
