What Is Cryptocurrency? - Working, Use Cases, Risks Involved and Popular Cryptocurrencies

What Is Cryptocurrency?

It is true that we are living in a digital era and what is a digital era without a digital currency? This is what cryptocurrency is. It is a digital form of currency that we can buy or sell over the internet. Cryptocurrency uses different encryption techniques in the generation of coins and verification of fund transfers. Different cryptocurrencies are based on various methods and technologies. Traditional currencies like dollars, euros, or yen are issued by the governments. Meanwhile, cryptocurrencies are blockchain-based currencies that operate on decentralized networks. This decentralized nature offers users unique autonomy. Cryptocurrencies also offer their users a peer-to-peer system allowing them to receive and send payments without third-party involvement i.e. banks. Many people also make money in this field by just following the highly accurate crypto signals from different providers.

How Does Cryptocurrency Work?

Cryptocurrencies work on blockchain technology. Blockchain is like a distributed ledger recording all the transactions being made on the network. The term blockchain itself describes the structure in which multiple blocks of data containing transactional information form a chain by linking together.

Verification of crypto transactions is done by a decentralized computer network, where all the computers are known as nodes. These nodes solve complex mathematical problems by coordinating with each other. This process is called mining. This verification provides security and immutability as it ensures that once added to a blockchain, a transaction cannot be altered.

Key Components of Cryptocurrency

Blockchain

It is the underlying technology used to power cryptocurrencies. It acts like a secure ledger.

Wallet

They are storage spaces used to store public and private keys. These keys are used for sending and receiving cryptocurrency. These wallets can be of two types, hot and cold.

Private And Public Keys

Every wallet contains two keys, which are public and private, a public key is like an address, and a private key is like a password. The public key is shared among users to receive funds but the private key is kept secure and only used to access other stored cryptocurrencies.

Popular Cryptocurrencies

You may know Bitcoin, as it is the most popular cryptocurrency. But there are thousands of other cryptocurrencies which are known as altcoins. Every altcoin has unique features, and you need a purpose in the financial system. Let's find out about the most famous cryptocurrencies:

Bitcoin BTC

Bitcoin was created by an anonymous person or a group named Satoshi Nakamoto in 2009. Bitcoin is known to be the first cryptocurrency and it has a fixed supply of 21 million coins. Due to its limited supply, Bitcoin is also referred to as "digital gold."

Ethereum ETH

Ethereum is the second most known cryptocurrency. It was launched in 2015 and is a platform for decentralized applications and smart contracts. Ethereum also introduced a programmable blockchain, which allows developers and associates to create complex financial services and products on this network.

Ripple XRP

Ripple is not like Ethereum or Bitcoin, as it was designed for fast and low-cost international payments. It is mainly and widely used by financial institutions and banks in cross-border transactions.

Litecoin LTC

It was created in 2011 by Charlie Lee. Litecoin can process transactions at the fastest speed by using a different mining algorithm known as Scrypt. It was created in the hope of being the "silver to Bitcoin's gold."

Tether USDT

It is a stablecoin, meaning that it is backed by a stable asset such as the US dollar. Stablecoin is less volatile than other cryptocurrencies and it is very useful as a store of value and for payments.

Use Cases Of Cryptocurrency

Digital payments

Cryptocurrencies like Ethereum and Bitcoin are commonly used as payment methods for goods and services. On the other hand, stablecoins like Tether have enabled low-cost transactions due to their low volatility. Cryptocurrencies can be used as a faster and more secure digital payment method.

Investments

Cryptocurrencies are known to be a type of investment because of their high volatility. The crypto market is very unpredictable, and the prices can see large fluctuations. But still, early investors of Ethereum and Bitcoin have made a significant amount of profit from their investments.

Cross-border payments

Cryptocurrencies have eliminated the need for third-party involvement in international money transfers. Which, as a result, causes reduced fees and reduced transactional time. There are cryptocurrencies specially designed for this purpose like Stellar XLM and Ripple XRP.

Tokenization of assets

Cryptocurrency can be used to tokenize real-world assets such as art, real estate, and commodities. In this process, a token representing the ownership of such assets is issued, which allows fractional ownership and improves liquidity.

Risks Involved

●        The biggest risk involving cryptocurrencies is volatility, meaning that the price of any cryptocurrency can fluctuate at times. While looking for an example, we can consider bitcoin's price, which has seen multiple exponential growths and crashes. This volatility is also a hurdle in the adoption of cryptocurrencies as an everyday currency.

●        Cryptocurrency provides very good security due to its blockchain technology. But crypto wallets and exchanges are not safe from hackers. There are multiple cases of high-profile breaches in which cryptocurrencies worth millions of dollars got stolen and left investors with empty wallets.

●        Cryptocurrencies provide people with an anonymous identity, which is also very attractive to scammers. In the early days of cryptocurrency, there were multiple initial coin offering scams where fake projects raised money and then disappeared. Other scams, like phishing attacks and Ponzi schemes, are also robbing people of their money.

Since the introduction of Bitcoin cryptocurrencies have achieved many milestones which point towards a brighter future. The new development like the introduction of CBDC (Central Bank Digital Currencies), shows that they will be a constant part of our daily lives. Cryptocurrencies have shifted the way we think about money and other financial systems. Cryptocurrencies provide an autonomous and broader financial system with their blockchain technology and decentralized nature. But with all of these promises, many risks cannot be overlooked. You can say that with the potential growth of other digital currencies, cryptocurrency can redefine the whole financial landscape for upcoming generations.
