What is cryptocurrency?
At its core, cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike conventional currencies issued by governments (often referred to as fiat currencies), cryptocurrencies are decentralized and typically operate on a technology called blockchain.
Blockchain is the underlying technology that powers cryptocurrencies. It is a distributed ledger system that records all transactions across a network of computers. This ledger is immutable and transparent, making it highly secure. Each transaction is grouped into a “block” and linked together in a “chain”, hence the name “blockchain”.
✪ History of Cryptocurrencies
The history of cryptocurrency is relatively short, but it is marked by significant milestones:
✪ Bitcoin Emerges (2009): The first cryptocurrency, Bitcoin, was created by an anonymous person or group using the pseudonym Satoshi Nakamoto. Bitcoin introduced the concept of a decentralized digital currency.
✪ Altcoins (2011): After the success of Bitcoin, alternative cryptocurrencies, called “altcoins”, began to emerge. Litecoin, created by Charlie Lee, was one of the first and served as a faster and more lightweight alternative to Bitcoin.
✪ Initial Coin Offerings (ICOs) (2013): ICOs have gained popularity as a way for new projects to raise capital by selling their own cryptocurrency tokens.
✪ Rapid Expansion (2017): In 2017, the cryptocurrency market experienced a phenomenal boom with the price of Bitcoin at an all-time high and an increase in new investors.
