What is cryptocurrency?
Cryptocurrency is a digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (fiat), cryptocurrencies operate on decentralized networks based on blockchain technology. A blockchain is a decentralized and distributed ledger that records transactions across a network of computers. Each block in the chain contains a list of transactions, and once a block is completed, it is linked to the previous one, forming a chain of blocks (hence the blockchain).
Cryptocurrencies work on the principles of blockchain technology, a decentralized and distributed ledger system. The most well-known cryptocurrency, Bitcoin, introduced the blockchain concept, and many other cryptocurrencies have since adopted similar technologies.
How does cryptocurrency work?
Let's dive deeper and see how cryptocurrency works and the technology it is built on.
Blockchain technology
A blockchain is a chain of blocks, each containing a list of transactions. These blocks are linked in chronological and linear order, forming a chain. The entire history of transactions is stored on the blockchain. The blockchain is decentralized, meaning it is maintained by a network of computers (nodes) rather than a central authority. Each node on the network has a copy of the entire blockchain.
Cryptographic principles
Cryptocurrencies use cryptographic keys for security. Each participant in the network has a pair of keys—a public key (known to others) and a private key (kept secret). The private key is used to sign transactions, while the public key is used to verify the signature. Transactions are secured with digital signatures generated using the private key. The signature ensures the authenticity and integrity of the transaction.
Decentralized ledger and transparency
Once a block is added to the blockchain, altering or tampering with its information is difficult. This immutability adds a layer of security and trust to the system.
Mining and validation
In PoW-based (Proof of Work) cryptocurrencies like Bitcoin, miners compete to solve complex mathematical problems. The first one to solve the problem gets the right to add a new block to the blockchain and is rewarded with newly minted cryptocurrency and transaction fees. Other consensus mechanisms, such as Proof of Stake (PoS), rely on validators who are chosen to create new blocks based on the amount of cryptocurrency they hold and are willing to "stake" as collateral.
Creation of new coins
In PoW-based cryptocurrencies, miners are rewarded with newly created coins when they successfully add a new block to the blockchain. This process is known as the "block reward."
Wallets
Users need a digital wallet to store and manage their cryptocurrency investments. Cryptocurrency Wallets store private keys, allowing users to access and control their funds.
Understanding these fundamental concepts provides a foundation for grasping how cryptocurrencies work. It's important to note that different cryptocurrencies may have variations in their specific implementations and consensus mechanisms.

What are crypto exchanges?
Cryptocurrency exchanges are online platforms that facilitate the buying, selling, and trading various cryptocurrencies. They serve as intermediaries, connecting buyers and sellers, and provide a marketplace for users to exchange digital assets.
Features of crypto exchanges
- Trading pairs. Exchanges list various cryptocurrency pairs, such as BTC/USD or ETH/BTC, indicating the exchange rate between two cryptocurrencies or between a cryptocurrency and fiat currency (like the US Dollar).
- Market orders and limit orders. When users buy or sell a cryptocurrency at the current market price, it is a market order, and the order is executed instantly. When users set a specific price at which they want to buy or sell, it is a limit order.
- Fiat-to-crypto and crypto-to-crypto exchanges. Fiat-to-Crypto Exchanges allow users to trade fiat currency (like USD, EUR, etc.) for cryptocurrencies, and Crypto Exchanges focus on trading one cryptocurrency for another.
- Security measures. Reputable exchanges implement security measures like two-factor authentication (2FA), cold storage for user funds, encryption, and regular security audits to protect users' assets.
- Liquidity. Liquidity refers to the ease with which an asset can be bought or sold without affecting its price significantly. High-liquidity exchanges generally have a large number of buyers and sellers, providing better opportunities for trading.
- Trading fees. Exchanges charge fees for executing trades. Fees may vary, including maker fees (for placing limit orders) and taker fees (for market orders).
- Regulation. Cryptocurrency exchanges operate under different regulatory environments globally. Some adhere to strict regulatory standards, while others operate in jurisdictions with fewer regulations.
Examples of popular cryptocurrency exchanges include Coinbase, Binance, Kraken, and Bitfinex. You need to choose exchanges based on factors such as security, fees, available trading pairs, and regulatory compliance. Additionally, you should exercise caution and conduct thorough research before trusting any exchange with their funds.

Crytocurrency vs. crypto tokens
Cryptocurrency and crypto tokens are related terms but refer to different concepts within the broader blockchain and digital asset space. Let's explore the differences between cryptocurrency and crypto tokens.
A cryptocurrency is a type of digital currency that uses cryptography for security. It operates on decentralized networks, usually based on blockchain technology. The most well-known cryptocurrency is Bitcoin (BTC), but there are thousands of others, often referred to as altcoins. On the other hand, crypto tokens are a type of digital asset created and issued on existing blockchain platforms. These tokens represent a unit of value and can have various use cases, such as accessing a specific application or representing ownership in a particular project.
Characteristics
- Decentralization. Cryptocurrencies are typically decentralized, meaning they are not controlled by any central authority like a government or financial institution.
- Medium of exchange. Cryptocurrencies are designed to be used as a medium of exchange for goods and services. They aim to provide an alternative to traditional fiat currencies.
Examples
- Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Ripple (XRP), and many others are examples of cryptocurrencies.
- Ethereum-based Tokens. Many tokens are created using the Ether platform. Examples include Chainlink (LINK), Uniswap (UNI), and Maker (MKR).
Creation
- Blockchain Platforms. Tokens are created using existing blockchain platforms that support the creation of decentralized applications (DApps) and smart contracts. Ethereum is a prominent example of a blockchain platform that facilitates token creation.
Use Cases
- Utility Tokens. These tokens give users access to a specific product or service within a blockchain ecosystem. They are often used in decentralized applications.
- Security Tokens. These tokens represent ownership in an underlying asset or company and may provide dividends or other financial benefits.
- Governance Tokens. Tokens grant holders the right to participate in decision-making processes within a blockchain network.
The most popular cryptocurrencies
The popularity and rankings of cryptocurrencies can change rapidly due to market dynamics. However, some of the most popular and widely known cryptocurrencies include:
- Bitcoin (BTC). The first and most well-known cryptocurrency is often referred to as digital gold.

FAQs
Is NFT and cryptocurrency the same?
No, Non-Fungible Tokens (NFTs) and cryptocurrencies are not the same, although they share some similarities. Cryptocurrencies, such as Bitcoin and Ethereum, are digital or virtual currencies that use cryptography for security. Their primary purpose is to serve as a medium of exchange, a store of value, or a unit of account. NFTs, on the other hand, are unique digital assets that represent ownership or proof of authenticity of a specific item or piece of content. NFTs are often used to represent digital art, collectibles, music, video, and other digital or physical assets. Unlike cryptocurrencies, NFTs are non-fungible, meaning each token is distinct and cannot be exchanged on a one-to-one basis with another.
What is the golden rule of crypto?
The "golden rule" of crypto is often considered to be "Do Your Own Research" (DYOR). This phrase emphasizes the importance of individual responsibility and thorough research before making any decisions in the cryptocurrency space.
How can I start investing in crypto?
Before diving into cryptocurrency investments, it's crucial to understand the basics. Learn about blockchain technology, how cryptocurrencies work, and the specific projects you're interested in. Select a trustworthy cryptocurrency exchange to facilitate your transactions. Some popular exchanges include Coinbase, Binance, Kraken, and others. Ensure the exchange aligns with your needs in terms of security, user interface, and available cryptocurrencies. Choose the cryptocurrencies you want to invest in based on your research and investment goals. Bitcoin and Ethereum are commonly chosen by beginners, but there are thousands of other options (altcoins) to consider.
If you're new to cryptocurrency investing, consider starting with a small amount of money. This allows you to gain experience without exposing yourself to significant risk. As you become more comfortable and knowledgeable, you can adjust your investment strategy.
The bottom line
Cryptocurrencies are generally intended for use as a medium of exchange, while tokens can have diverse utility and value propositions within a particular blockchain network. It's essential for individuals considering investing in cryptocurrencies to conduct thorough research, understand the risks involved, and only invest what they can afford to lose. Diversifying one's investment portfolio, staying informed about market developments, and adopting a cautious approach is advisable when dealing with the volatile and evolving nature of the cryptocurrency market. Consulting with financial professionals for personalized advice is also recommended.
