Beginner’s Guide to What is Cryptocurrency & How Does It Work?

In this beginner’s guide to cryptocurrency, we explore what is cryptocurrency and how does crypto work.

Cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions and to control the creation of new units of a particular cryptocurrency. Cryptocurrency is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.

So, if you’ve been wondering about cryptocurrency and want to learn what it is and how it works, keep reading, and we will help you along with your crypto journey!

What is Cryptocurrency?

At its core, cryptocurrency is a digital or virtual currency system developed to function on an advanced technological framework called the blockchain. This groundbreaking system leverages state-of-the-art cryptography and the inherent characteristics of the blockchain, making these digital assets incredibly resilient against duplication or counterfeiting.

Envision a scenario where you must transfer money to a friend’s bank account. Usually, the bank acts as an intermediary, holding your funds and executing transactions on your behalf. It deducts the required sum from your account and credits it to your friend’s account.

However, you can transfer value directly across a network with cryptocurrencies, eliminating the need for an intermediary, such as a bank or remittance service. This is a monumental shift in the way value exchange happens.

Transactions made using cryptocurrencies are secure and anonymous. They are facilitated through a decentralized network of peers (commonly referred to as a peer-to-peer network). This ensures that no single authority controls the network, and your funds remain inaccessible without your explicit authorization.

In many ways, cryptocurrencies can offer heightened security compared to traditional financial systems. They are immune to conventional vulnerabilities. For instance, a malicious attacker cannot pilfer your funds unless they manage to access your unique and encrypted private keys.

How Does Cryptocurrency Work?

Cryptocurrency operates by leveraging a decentralized network structure known as the blockchain ledger. Think of the blockchain as an unalterable digital journal that meticulously logs every transaction associated with a specific cryptocurrency.

Cryptocurrencies employ a mechanism known as ‘mining’ to process transactions. This fascinating process involves a network of powerful computers running specialized software. Their task is to solve intricate mathematical problems. Upon cracking these problems, new ‘blocks’ of data are added to the blockchain. In return for their efforts, these ‘miners’ are compensated with a predetermined amount of the cryptocurrency they are mining.

Every transaction that occurs gets recorded on the blockchain, which is instantly accessible for public viewing. This level of transparency is a unique facet of cryptocurrencies. It ensures the security of transactions, as they are publicly available and can be verified by any participant on the network.

At the heart of the cryptocurrency ecosystem are ‘digital wallets‘. These are software applications that securely store your private and public cryptographic keys. These keys play a critical role in initiating and validating transactions. Furthermore, your digital wallet keeps track of your cryptocurrency balance.

The unique combination of decentralization, cryptographic security, transparency, and digital wallets makes cryptocurrencies a truly novel medium of exchange in the digital age. As we explore deeper into the mechanisms of cryptocurrencies, you will discover why this technology has the potential to redefine the future of finance.

What Makes Cryptocurrency Different from Traditional Money?

Cryptocurrencies have become a viable alternative to traditional fiat currencies, such as the US Dollar or Euro. Numerous factors contributing to this shift demonstrate how digital currencies offer superior advantages over their conventional counterparts. Here are a few key distinctions:

Global Accessibility and Efficiency:

Cryptocurrencies, such as Bitcoin and Ethereum, defy geographical constraints. You can transmit substantial amounts of money globally for a marginal transaction fee, making it cost-effective and expedient. The only requirement for the recipient is a cryptocurrency wallet to receive and store these digital assets. Statistically speaking, transferring Bitcoin is approximately 60 times more cost-effective and 48 times faster than executing an international wire transfer.


In contrast to credit card payments, transactions executed with cryptocurrencies cannot be reversed, providing an additional layer of security and transparency. As a result, verifying the recipient’s wallet address and the transaction amount twice before executing a transaction is crucial.


Traditional money transfers typically require a substantial amount of personal information, including the recipient’s bank account title, account number, and contact details. Cryptocurrencies, on the other hand, require only a wallet address. Neither party involved in the transaction must disclose any private information, not even their names. For those seeking an additional layer of privacy, cryptocurrencies like Monero or ZCash provide options to obscure wallet addresses and transaction amounts.

How Many Cryptocurrencies Are There?

The crypto market has over 8,000 unique cryptocurrencies. Bitcoin, Ethereum and Ripple are the most prominent, collectively making up the majoirty of the total market capitalization in the cryptocurrency space.

Many of these digital currencies bear the label ‘Altcoins’, indicating their status as alternatives to the pioneer cryptocurrency, Bitcoin. These Altcoins often introduce unique features that distinguish them from Bitcoin. For instance, some promise faster transaction speeds, others prioritize enhanced privacy, and a few even build specialized ecosystems.

As the world of cryptocurrencies continues to evolve, it’s important to stay informed about these different cryptocurrencies and their unique offerings. Each has its value proposition, technological foundation, and potential use cases. The range of possibilities is astounding from payment solutions to smart contracts and decentralized applications.

Types of Cryptocurrencies

Cryptocurrencies are a diverse breed, with several different types, each with distinct attributes and applications. Let’s examine some of the most notable cryptocurrencies and their unique features or uses:

  • Bitcoin: Often heralded as the flagship of cryptocurrencies, Bitcoin is a decentralized digital currency. It’s extensively used as a store of value (digital gold, as some might say) and a medium for exchange. Bitcoin’s inherent design makes it resilient to censorship and interference.
  • Ethereum: Ethereum is more than just a cryptocurrency. It’s a blockchain-based platform that facilitates the creation and execution of smart contracts and decentralized applications (dApps). Ethereum’s native cryptocurrency, Ether, powers these applications.
  • Ripple (XRP): Ripple is a cryptocurrency (XRP) and a cutting-edge digital payment protocol. It’s designed to facilitate swift, secure money transfers, often providing a lifeline for international remittances.
  • Litecoin: Created as a ‘lite’ version of Bitcoin, Litecoin is designed for efficiency. It offers faster transaction confirmation times and a different hashing algorithm.
  • Bitcoin Cash: Bitcoin Cash emerged as a hard fork of Bitcoin. Its design offers lower transaction fees and swifter transaction processing times, addressing some of Bitcoin’s scalability issues.

Beyond these major players, there are other types of cryptocurrencies, such as privacy coins, stablecoins, and utility tokens.

  • Privacy Coins: These cryptocurrencies prioritize user anonymity and privacy. They employ techniques to obscure the transaction ledger, making it challenging to trace transactions back to users.
  • Stablecoins: Stablecoins aim to combat the price volatility typical in the crypto space. They are pegged to stable assets like traditional fiat currencies or commodities, offering a stable price point.
  • Utility Tokens: These tokens are digital coupons that give holders access to specific features or services on a particular platform.

The diversity of cryptocurrencies offers users different advantages and opportunities. Understanding these differences is a critical step in navigating the cryptocurrency landscape.

There are several different types of cryptocurrencies, each with unique features and uses. Some of the most popular cryptocurrencies and their features/uses are;

How Does Cryptocurrency Derive Value?

Much like any other tradable asset, the value of cryptocurrencies is primarily determined by market supply and demand dynamics.

Cryptocurrencies today serve many purposes, from facilitating cross-border transactions to executing smart contracts. Their practical uses often generate demand and, in turn, value. Take, for example, the Ripple cryptocurrency (XRP), which is used for efficient cross-border transactions. If people were to cease using XRP for this purpose, demand would plummet, resulting in a consequent drop in value.

For those considering a cryptocurrency investment, it’s crucial to understand what drives its demand and to evaluate the sustainability of this demand in the future. After all, a cryptocurrency is only as valuable as the perceived utility it offers its users.

With the rapid expansion of the cryptocurrency universe, it’s evident that these digital assets will play a significant role in future economic systems. To capitalize on this transformative innovation, you should thoroughly research promising cryptocurrency projects that present a clear and tangible value proposition.

Remember, a cryptocurrency’s value isn’t solely in its current price. Instead, it’s rooted in the problem it solves, the utility it provides, and its potential for adoption. The more a cryptocurrency can do these things, the more likely it is to sustain demand and its value over time.

Where to Buy Cryptocurrency?

You can purchase cryptocurrencies from a myriad of sources, spanning both online and offline platforms. Among the most prevalent destinations for buying cryptocurrencies are cryptocurrency exchanges.

  • Binance: Binance is one of the leading cryptocurrency exchanges globally. It offers an extensive range of digital currencies, including Bitcoin, Ethereum, Ripple, and Litecoin. Binance is lauded for its extensive features, liquidity, and security.
  • Coinbase: Coinbase is another well-established name in the crypto sphere. This user-friendly platform enables customers to buy and sell various cryptocurrencies with fiat currencies. Users can make purchases using debit cards or connect directly to their bank accounts.
  • OKX: OKX is a robust cryptocurrency exchange offering a diverse spectrum of coins for both spot and futures trading. With its advanced trading features, OKX caters to a broad demographic of crypto traders.

Apart from these centralized exchanges, other avenues for buying cryptocurrencies include:

  • Decentralized Exchanges (DEXs): DEXs such as UniSwap allow peer-to-peer trading, cutting out the middleman. Transactions are conducted directly between users on the blockchain.
  • Peer-to-Peer Trading: In P2P trading, individuals can buy and sell cryptocurrencies directly with each other. Some platforms offer an escrow service for added security.
  • Crypto ATMs: These are similar to traditional ATMs but for cryptocurrencies. Users can buy cryptocurrencies with cash or a debit card at a crypto ATM.

When buying cryptocurrencies, it’s essential to consider security, fees, ease of use, and the types of available cryptocurrencies.
