Bitcoin

Bitcoin is a digital asset and a payment system invented by an unknown person or group of people under the name Satoshi Nakamoto. Transactions are verified by network nodes through cryptography and recorded in a public dispersed ledger called a blockchain.

Bitcoin is unique in that there are a finite number of them: 21 million. They can be traded between people and businesses, and are also held as investments.Bitcoins have been controversial since their creation, with some arguing they are a Ponzi scheme, while others believe that they could represent the future of money. Despite this, bitcoin remains active and has seen large increases in value over the past few years.
