What Is Cryptocurrency and How Does It Work?
Cryptocurrency is a digital or virtual currency that uses cryptography for security. it is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Cryptocurrencies are decentralized, not subject to government or financial institution control. For example, Bitcoin, the first and most well-known cryptocurrency, was created in 2009 by an anonymous individual or group known as Satoshi Nakamoto. They’re often traded on decentralized exchanges and can also be used to purchase goods and services. The popularity of cryptocurrencies has grown exponentially in recent years. As of June 2017, over 1,100 different cryptocurrencies were in circulation with a total market capitalization of over $100 billion. Bitcoin alone accounted for around $40 billion of this total.
The popularity of cryptocurrency trading has also led to numerous online exchanges. These exchanges allow individuals to buy and sell them using traditional fiat or other cryptocurrencies.
Cryptocurrencies have seen a tremendous amount of growth since their inception. However, they have also been subject to extreme volatility and are known to lose large percentages of their value in short periods. Therefore, investors must be cautious when investing in cryptocurrencies and only support what they are willing to lose.
How does cryptocurrency work?
Cryptocurrency works on blockchain technology. A blockchain is a digital ledger of all its transactions. Each block in the chain contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the blockchain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that are already elsewhere.
Cryptocurrency is held in a digital wallet and can be used to purchase goods and services or traded for other currencies, such as traditional fiat currencies or other cryptocurrencies. Furthermore, people can earn cryptocurrency through a process called “mining.” Miners are rewarded with cryptocurrency for verifying and committing transactions to the blockchain.
