What Is Cryptocurrency and How Does It Work? A Simple Guide for Beginners
Cryptocurrency has exploded from a niche concept, to a global finance movement. Between Bitcoin, Ethereum, Solana and an endless list of other names making headlines, everyone is scratching their heads, and wondering two things: how does this digital currency actually work (and why is it so popular)? And what are the risks and benefits of it? Here is a full, beginner's guide to the concepts behind cryptocurrency.
Understanding Cryptocurrency
To start with, cryptocurrency is a type of digital money that is secured by cryptography. The main difference between traditional currency (like dollars and euros) and cryptocurrency, is that the latter exists only in digital form, and it is not issued or regulated by any government or central bank. In effect, this means you can send and receive it without a third party (such as a bank or financial institution).
With traditional currency, like dollars or euros, a central system (such as a bank) is required to verify the transaction. In cryptocurrency, the transactions are verified by a decentralized system of many computers that all exist globally.
How Does It Work?
Cryptocurrency is built on a technology called blockchain. You may think of the blockchain as a public digital ledger — imagine a notebook listing every transaction that takes place, where each transaction is validated and cannot be modified.
Every transaction is recorded in a "block," and as soon as the block is filled, it will be linked to the previous block, creating a "chain." After someone sends someone cryptocurrency, the transaction is broadcasted to the network. Several computers validate the legitimacy of the transaction and when verified, the transaction is permanently recorded on the blockchain.
This process ensures security and transparency and disallows fraud.
What Is Mining?
Powerful computers on the blockchain solve complex mathematical problems to validate transactions on the blockchain. This process of validating is called mining. As these problems are solved, miners are given coins which is how cryptocurrencies like Bitcoin are created and distributed.
However, not every cryptocurrency operates using mining; some use different methods like Proof of Stake, which instead of determining who gets to validate the block with computational power, it selects validators based on how many coins they own.
Cryptocurrency as a Form of Investment
Though cryptocurrencies were originally conceived as exchange media, many people treat them as investments. The respective prices of coins like Bitcoin have experienced enormous short-term fluctuations. For example, you could have bought Bitcoin for $500 in 2016 and seen it reach $60,000 during 2024.
As previously indicated, prices can fall just as dramatically as they can rise in the very short term. For example, Bitcoin was approximately $45,000 in May 2022, but had fallen to approximately $16,000 by December 2022. This gives a perspective of the risk associated with cryptocurrency as an asset class.
Common Cryptocurrency Terminology
Altcoin: Any cryptocurrency besides Bitcoin. These may include Ethereum, Solana, and meme-coins like Dogecoin.
Wallet:
A service that allows you to save both public and private keys so you can send and receive cryptocurrency. There are hot wallets (i.e., accessed through the internet) and cold wallets (i.e., offline asset storage).
Keys:
The public key is like a bank account number; the private key is like a password; treat both like your accounts and password were lacking any sort of security! The key to successfully using cryptocurrency is ensuring that your private key is consistently or as often as you can, backed up from loss or theft.
Fork:
Any time a change has been made to the protocol of a blockchain, you are likely to hear about "forking" which essentially means that the cryptocurrency you either actually or hypothetically owned now has another version. For example, Bitcoin Cash forked from Bitcoin.
Cryptocurrency Pros
Decentralization: There is no central authority that controls cryptocurrency. This offers more freedom and financial independence for consumers.
Accessibility: Anyone in the world with internet access can access the crypto economy. No need for a traditional bank account.
Speed and Cost: Digital currencies transact quickly and also come with lower fees than other forms of payment. This is especially true for international payments.
Transparency and Security: Cryptocurrencies are easily traceable, and the blockchain makes transactions secure. All transactions on any given blockchain will be registered in the ledger.
Potential High Returns: Cryptocurrencies have shown enormous growth, however, investors have also experienced losses. Investments with high after hour leasing risks create volatilty and uncertainty.
Cryptocurrency Cons
High Volatility: Prices can vary so much within hours, it is possible to have made a profit or a loss.
Use in Illegal Activity: Cryptocurrencies have often been used in illegal transactions because they are relatively anonymous.
Lack of Regulation: Not all countries understand how to regulate cryptocurrencies making it uncertain for all investors.
Scams and Fraud: Scams related to fake websites, phishing scams, and fraudulent tokens are easily found in the crypto space. Always be sure to vet a site before purchasing or investing.
Irreversible: Cryptocurrencies transact in an irreversible way. Bank transfers are reversible, throughout the blockchain cryptocurrencies are not. If you send coins to the wrong address, your cryptocurrency is permanently lost.
Should You Get Into Cryptocurrency?
Cryptocurrency may provide compelling opportunities for innovation and investment, but it also has its risks. Whether you’re interested in using it for buying things, trading it, or investing, you need to learn and understand how it works.
Before you take the plunge into the world of crypto:
Do your own research
Don’t act on emotion
Be aware of hype and scams
Don’t invest more than you can afford to lose
Cryptocurrency may be the future of money, or it may be a niche use of money. Either way, knowledge is your best friend.
