Cryptocurrency is a digital payment system that does not rely on banks to verify transactions. It is a peer-to-peer system that enables anyone to send and receive payments anywhere.

Rather than moving and exchanging physical money in the real world, cryptocurrency payments exist purely as digital entries in online databases describing specific transactions.

When you transfer cryptocurrency funds, the transaction is recorded in a public ledger. Cryptocurrencies are stored in a digital wallet.

The cryptocurrency got its name because it uses encryption to verify transactions. This means that advanced coding is involved in storing and transmitting cryptocurrency data between wallets and public ledgers. The purpose of encryption is to provide security and protection.

The first cryptocurrency was bitcoin, which was founded in 2009 and is still the best known today. Much of the interest in cryptocurrency is to trade for profit, with speculators at times seeing prices skyrocket.

What is cryptocurrency?

Cryptocurrency Example

There are thousands of cryptocurrencies. Some of the most famous include:

bitcoin:

Founded in 2009, bitcoin was the first cryptocurrency and is still the most traded. The currency was developed by Satoshi Nakamoto – widely considered a pseudonym for an individual or group of people whose exact identity remains unknown.

Ethereum:

Developed in 2015, Ethereum is a blockchain platform that has its own cryptocurrency, called Ether (ETH) or Ethereum. It is the most popular cryptocurrency after bitcoin.

Litecoin:

The currency is similar to bitcoin but has evolved more quickly to develop new innovations, including a process allowing faster payments and more transactions.

Wave:

Ripple is a distributed ledger system that was established in 2012. Ripple can be used to track a wide variety of transactions, not just cryptocurrencies. Behind this, the company has worked with various banks and financial institutions.

Non-Bitcoin cryptocurrencies are known collectively as “altcoins” to distinguish them from the original.

What is a Blockchain?

A blockchain is an open, distributed ledger that records transactions in code. In practice, it is like a checkbook that is distributed to countless computers around the world.

Transactions are recorded in “blocks” which are then linked together over a “chain” of previous cryptocurrency transactions.

“Imagine a book where you spend money every day,” says Buchi Okoro, CEO and co-founder of the African cryptocurrency exchange Quidax. “Each page is like a block, and the whole book, a set of pages, is a blockchain.”

With a blockchain, everyone who uses cryptocurrency has their own copy of this book to create a unified transaction record.

The software logs each new transaction as it occurs, and each copy of the blockchain is updated simultaneously with new information, keeping all records identical and accurate.

To prevent fraud, each transaction is verified using one of two main verification techniques: proof of work or proof of stake.

Understanding Cryptocurrencies

Cryptographic currencies are digital or virtual currencies based on cryptographic systems. They enable secure online payments without the use of third-party intermediaries.

“Crypto” refers to the various encryption algorithms and cryptographic techniques that protect these entries, such as elliptic curve encryption, public-private key pairs, and hashing functions.

Cryptocurrencies can be mined or purchased from cryptocurrency exchanges. Not all e-commerce sites allow purchases using cryptocurrencies. In fact, cryptocurrencies, even popular cryptocurrencies like bitcoin, are rarely used for retail transactions.

However, the skyrocketing value of cryptocurrencies has made them popular as trading instruments. To a limited extent, they are also used for cross-border transfers.

How does Cryptocurrency work?

Cryptocurrency is a medium of exchange that is digital, encrypted, and decentralized. Unlike the US dollar or the euro, there is no central authority that manages and maintains the value of a cryptocurrency. Instead, these functions are widely distributed among users of the cryptocurrency via the Internet.

You can use crypto to buy regular goods and services, although most people invest in cryptocurrency as much as they invest in other assets such as stocks or precious metals.

While cryptocurrency is a novel and exciting asset class, buying it can be risky as you will need to do a fair amount of research to fully understand how each system works.

Types of Cryptocurrency

Bitcoin is the most popular and valuable cryptocurrency. It was invented by an anonymous person named Satoshi Nakamoto and presented to the world through a white paper in 2008. There are thousands of cryptocurrencies in the market today.

Each cryptocurrency claims to have a different function and specification. For example, Ethereum’s ether markets itself as a gas for the underlying smart contract platform. Ripple’s XRP is used by banks to facilitate transfers between different geographies.

Bitcoin, which was made available to the public in 2009, remains the most widely traded and covered cryptocurrency.

As of November 2021, there were over 18.8 million bitcoins in circulation with a total market cap of approximately $1.2 trillion. Only 21 million bitcoins will exist.3

In the wake of the success of bitcoin, several other cryptocurrencies, known as “altcoins”, have been launched. Some of these are clones or forks of bitcoin, while others are new currencies that were created from scratch.

These include Solana, Litecoin, Ethereum, Cardano, and EOS. As of November 2021, the total value of all cryptocurrencies in existence exceeded $2.1 trillion—Bitcoin represented about 41% of that total value.4

How can you mine cryptocurrency?

Mining is how new units of cryptocurrency are issued into the world, usually in exchange for validating transactions. While it is theoretically possible for the average person to mine cryptocurrency, it is increasingly difficult to prove work systems such as bitcoin.

“As the bitcoin network grows, it becomes more complex, and requires more processing power,” says Spencer Montgomery, founder of Uinta Crypto Consulting.

“The average consumer used to be able to do this, but now it’s too expensive. There are a lot of people who have adapted their devices and technology to get better.”

And remember: Proof of Work cryptocurrencies requires an enormous amount of energy to mine. It is estimated that 0.21% of all the electricity in the world goes to power bitcoin farms. This is about the same amount of power as Switzerland uses in a year. It is estimated that most bitcoin miners use 60% to 80% of the earnings from mining to cover the cost of electricity.

While it is impractical for the average person to earn crypto by mining in proof of work, the way of high-powered computing requires less proof of stake model as validators are randomly assigned based on the amount they stake. is chosen.

However, it is necessary that you already have a cryptocurrency in order to participate. (If you don’t have any crypto, you have nothing to bet.)

How to Buy Cryptocurrency

There are four basic steps involved in buying cryptocurrency:

Decide Where to Buy It

There are many ways to buy cryptocurrency, although the most accessible method for beginners is likely to be a centralized exchange. Centralized exchanges act as third parties overseeing transactions to give customers confidence that they are getting what they pay for. These exchanges usually sell crypto at market rates, and they make money on fees for various aspects of their services.

If you are more accustomed to traditional brokerage accounts, there are some online brokers that offer access to cryptocurrencies as well as stocks. Online brokers reviewed by NerdWallet include Robinhood, Weebly, SoFi Active Investing, and TradeStation. If you are looking for an exchange that operates solely in the world of cryptocurrency, check out Pure-Play Crypto Exchange. These platforms, such as Coinbase, Gemini, and Kraken, won’t give you access to core assets like stocks and bonds, but they usually have a better selection of cryptocurrencies and more on-platform crypto storage options.

Although centralized exchanges are relatively easy to use, they can also be an attractive target for hackers given the volume of crypto.

For more advanced users, there are decentralized exchanges whose fees can be less than what centralized platforms charge. They can be more difficult to use and demand more technical know-how, but they can also provide some security benefits as there is no single target for a cyberattack. Cryptocurrency can also be traded through peer-to-peer transactions.

Choose How You’ll Pay

While there are thousands of cryptocurrencies being traded around the world, you will find that the most popular options are widely available for purchase in fiat currencies such as the US dollar. If you are a first-time buyer, you are very likely to use regular money to buy cryptocurrency.

If you are a more experienced investor, you may want to trade some of your existing crypto holdings for another type of cryptocurrency – Bitcoin for Ethereum, for example.

Add Value to Your Account

Depending on the method you choose to pay with, you may need to deposit funds into your account before you can buy any crypto. If you are using fiat currency, most exchanges allow debits and bank transfers. Some even allow you to make purchases with your credit card, although this can be a risky move with volatile assets like cryptocurrencies because the interest costs can deepen your losses if the value of your investment declines.

If you already have cryptocurrency, you can transfer it to your account from a digital wallet or another platform, then use it to trade. Just be sure to verify that your crypto exchange allows trading between the assets you are looking at. Not all cryptocurrencies can be directly traded for each other, and some platforms have more trading pairs than others.

Another thing to note is that exchange fees depend on what you’re buying and how you’re buying it, so review these details carefully.

Choose a Cryptocurrency

There are many options for cryptocurrency investors, although they are not likely to be right for everyone. Before you buy, ask yourself what your goals are for this investment. Are you expecting it to increase in value? Are you interested in transacting using cryptocurrency? Are you interested in harnessing the underlying technology through decentralized apps? These can help you make your decision.

NerdWallet has created guides for some widely circulated cryptocurrencies including bitcoin and some bitcoin alternatives:

Bitcoin is the first and most valuable cryptocurrency.

Ethereum is typically used to perform more complex financial transactions than those backed by bitcoin.

Cardano is a competitor to Ethereum, led by one of its co-founders.

Solana is another competitor to Ethereum that emphasizes speed and cost-effectiveness.

Dogecoin started out as a joke but has become one of the most valuable cryptocurrencies.

Stablecoins are a class of cryptocurrencies whose values are designed to remain stable relative to real-world assets.

Who created Bitcoin?

To really understand how bitcoin works, it helps to start at the beginning. The question of who created bitcoin is a fascinating one because a decade after the technology was invented—and despite much digging by journalists and members of the crypto community—its creators remain anonymous.

What is the point of Cryptocurrency?

Cryptocurrencies are a new paradigm for money. His promise is to streamline the existing financial structure to make it faster and cheaper.

Their technology and architecture decentralize existing monetary systems and make it possible for transacting parties to exchange value and money independently of intermediary institutions such as banks.

Pros and Cons of Cryptocurrency

Cryptocurrency inspires sentimental opinion across a spectrum of investors. Here are some reasons why some believe it’s a transformational technology, while others worry it’s a fad.

cryptocurrency pros

Supporters see cryptocurrencies like bitcoin as the currency of the future and are rushing to buy them now, possibly before they become more valuable.

Some proponents like the fact that cryptocurrency removes central banks from managing the money supply because over time these banks reduce the value of money through inflation.

Other advocates like the blockchain technology behind cryptocurrencies, as it is a decentralized processing and recording system and can be more secure than traditional payment systems.

Some speculators like cryptocurrencies because they are increasing in value and are not interested in the long-term acceptance of currencies as a way to move money.

Some cryptocurrencies offer their owners the opportunity to earn passive income through a process called staking. Crypto staking involves using your cryptocurrency to help you verify transactions over the blockchain protocol. Although placing a bet has its risks, it can allow you to increase your crypto holdings without buying more.

Cryptocurrency Cons

Many cryptocurrency projects remain untapped, and blockchain technology, in general, is yet to see widespread adoption. If the underlying idea behind the cryptocurrency does not reach its potential, long-term investors may never see the return they hoped for.

For short-term crypto investors, there are other risks as well. Its prices change rapidly, and this means that while many people made quick money by buying at the right time, many others lost money by doing so just before the crypto crash.

Those wild changes in value could also cut against the original ideas behind the projects that were built to support cryptocurrencies. For example, people may be less likely to use bitcoin as a payment system if they are not sure what it will be worth the next day.

The environmental impact of bitcoin and other projects using similar mining protocols is significant. For example, the University of Cambridge comparison states that worldwide bitcoin mining consumes more than twice as much electricity as all US residential lighting. Some cryptocurrencies use a different technology that demands less energy.

Governments around the world have not yet fully figured out how to handle cryptocurrency, so regulatory changes and crackdowns have the potential to affect the market in unpredictable ways.

What is the difference between cryptocurrency and digital currency?
