3. What is Cryptocurrency?
A cryptocurrency is a digital currency or
digital asset. You can’t feel and see this. It
is an encrypted data string that denotes a
unit of currency. It is completely

the first cryptocurrency “Bitcoin”.

Cryptocurrencies run on a
distributed public ledger called
blockchain, a record of all
transactions updated and held by
currency holders. Units of
cryptocurrency are created through
a process called mining, which
involves using computer power to
solve complicated mathematical
problems that generate digital
assets.

Bitcoin is a decentralized digital currency, without
a central bank or single administrator, that can be
sent from user to user on the peer-to-peer bitcoin
network without the need for intermediaries.

use in illegal transactions, a large amount of
electricity and thus carbon footprint used by
mining, and price volatility. Bitcoin inventor Satoshi
