What is Cryptocurrency?
A cryptocurrency is a type of digital money that is driven by blockchain technology and secured by encryption. Cryptocurrency is decentralised, which means that no one entity has control over it like traditional money, which is governed by banks or governments.
Key Features of Cryptocurrency:
- Decentralization – Not controlled by any government or bank.
- Peer-to-Peer Transactions – Send and receive money directly without intermediaries.
- Security – Transactions are encrypted and nearly impossible to counterfeit.
- Limited Supply – Many cryptocurrencies have fixed supply, protecting them from inflation.
History of Cryptocurrency
With eCash in the 1980s and DigiCash in the 1990s, the idea of digital currency first emerged. None of these systems, nevertheless, were adopted globally.
Bitcoin was first presented in 2008 by an unidentified individual (or group) going by the name Satoshi Nakamoto in a whitepaper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” With this, blockchain-based cryptocurrencies were formally born.
