What Is CryptoCurrency?  

  A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that 

uses cryptography to secure its transactions, to control the creation of additional units, and to verify the 

transfer of assets. Cryptocurrencies are a type of digital currencies, alternative currencies and virtual 

currencies. Cryptocurrencies use decentralized control as opposed to centralized electronic money and central 

banking systems. The decentralized control of each cryptocurrency works through a blockchain, which is a 

public transaction database, functioning as a distributed ledger.    Bitcoin, created in 2009, was the first 

decentralized cryptocurrency. Since then, numerous other cryptocurrencies have been created. These are 

frequently called altcoins, as a blend of alternative coin.  

    What Is BitCoin?

   Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as

 the system works without a central bank or single administrator. The network is peer-to-peer and transaction

s 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 an unknown person or group of people under the name Satoshi Nakamoto and released as open-

source software in 2009.
