Cryptocurrency – Meaning and Definition
Cryptocurrency, often referred to as digital currency or simply "crypto," is a form of currency that exists digitally or virtually and uses cryptography to secure transactions. Unlike traditional currencies, cryptocurrencies operate without a central issuing or regulating authority, relying instead on decentralized systems to record transactions and issue new units.
Understanding Cryptocurrency
Cryptocurrency is a digital payment system that doesn't rely on banks to verify transactions. It operates on a peer-to-peer network, enabling anyone worldwide to send and receive payments. Unlike physical money, cryptocurrency payments exist purely as digital entries in an online database describing specific transactions. When you transfer cryptocurrency funds, the transaction is recorded in a public ledger. Cryptocurrencies are stored in digital wallets.
The term "cryptocurrency" stems from its use of encryption to verify transactions. Advanced coding is involved in storing and transmitting cryptocurrency data between wallets and public ledgers. The primary goal of encryption is to provide security and safeguard transactions.
Bitcoin, launched in 2009, was the first cryptocurrency and remains the most well-known. Much of the interest in cryptocurrencies revolves around trading for profit, with speculators sometimes driving prices skyward.
How Cryptocurrency Works
Cryptocurrencies operate on a decentralized public ledger called blockchain, a record of all transactions updated and held by currency holders.
New cryptocurrency units are created through mining, a process that involves using computer power to solve complex mathematical problems that generate coins. Users can also purchase cryptocurrencies from brokers, then store and spend them using cryptographic wallets.
Owning cryptocurrency doesn't mean possessing a physical asset. Instead, you hold a key that allows you to transfer a record or unit of measure from one person to another without trusting a third party.
While Bitcoin has been around since 2009, the applications of blockchain technology and cryptocurrencies continue to expand in finance, with more use cases expected in the future. Trading bonds, stocks, and other financial assets may eventually utilize this technology.
Common Cryptocurrencies
Thousands of cryptocurrencies exist. Here are some of the most well-known:
Bitcoin (BTC)
Launched in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin remains the most traded cryptocurrency.
Ethereum (ETH)
Developed in 2015, Ethereum is a blockchain platform with its own cryptocurrency, Ether (ETH). It’s the second-most popular cryptocurrency after Bitcoin.
Litecoin (LTC)
Similar to Bitcoin but faster in adopting innovations like quicker payments and higher transaction capacity.
Ripple (XRP)
Ripple is a distributed ledger system launched in 2012. It tracks various transaction types beyond cryptocurrencies and has partnered with banks and financial institutions.
Non-Bitcoin cryptocurrencies are collectively called altcoins to distinguish them from the original.
