How Cryptocurrency Works: In Simple Terms for Beginners

What Is Cryptocurrency in Simple Terms?

Cryptocurrency is a new type of financial asset that exists only in digital form and is used in the online economy. It can be stored in special digital wallets, sent to other users, and used to pay for goods or services online. Cryptocurrency is not issued by central banks or government financial institutions.

How Cryptocurrency Works: Basic Principles

Digital money has several key features.

• Security. It is virtually impossible to forge or alter cryptocurrency transaction data.
• Speed. Digital funds can be sent anywhere in the world in minutes. By comparison, international bank transfers can sometimes take several days.
• Affordability. Transaction fees are usually lower than those of traditional payment systems.
• Confidentiality. Transactions are carried out using crypto addresses rather than personal banking details.

What Technologies Do Cryptocurrencies Use?

To understand how cryptocurrency works, you need to learn about the technologies on which it is based.

Distributed system

One of the main features of cryptocurrencies is the absence of a single control center. While in traditional financial systems transactions go through banks, cryptocurrencies do not require such intermediaries. The system operates through a network of users around the world. Participants verify transactions and support the system's operation.

Blockchain

This is the name given to the network that stores transaction information. Data is recorded in blocks, each of which is linked to the previous one in a conditional "chain." This structure ensures the system's transparency and allows all transactions to be stored.

Cryptography

This method is also known as cryptography. It protects transactions and user data and confirms the owner's right to dispose of their funds. Thanks to cryptographic algorithms, no one can change a transaction or access someone else's funds without the appropriate keys.

Validation and mining

For transactions to be added to the blockchain, they must be verified — a process carried out by miners and validators. They receive financial compensation for their work: new coins and commissions paid by senders.  

During mining, computing power (processors, video cards, special ASIC devices) is used to solve complex mathematical problems. The participant who finds the answer first gets the right to add a new block.

Some cryptocurrencies use a validation mechanism. The principle remains the same — confirmation of transactions. To participate, you need to lock a certain amount of coins on the network (the mechanism of staking) and install special software (a node). The software connects to the cryptocurrency network, verifies the transfer, and contributes to the creation of new blocks. The node must be online at all times.

Crypto wallets and private keys

Special digital wallets are used to store cryptocurrency. With them, you can send and receive coins, track transaction history, and connect to decentralized applications.

Access to the wallet is protected by a private key — a unique combination of characters that confirms the owner's right to dispose of the cryptocurrency.

Consensus Algorithms in Cryptocurrencies

For a crypto network to operate without central control, participants need to agree on which transactions are valid. To do this, consensus mechanisms are used — a set of rules by which the network confirms transactions and adds new blocks.

Let's take a look at the most well-known mechanisms and how cryptocurrency works with them: 

• Proof-of-Work. In such networks, mining is used to verify transactions. Bitcoin, Litecoin, and other coins are based on PoW. 
• Proof-of-Stake. Here, blocks are confirmed by validators. PoS is used by cryptocurrencies such as Ethereum, Cardano, Solana, and others.

Thanks to the consensus mechanism, all network participants see the same confirmed transaction history.

How Does a Cryptocurrency Transaction Work in a Blockchain?

You can transfer funds to other users using cryptocurrency — here's how it works technically:

1. The user sends a transaction, specifying the recipient's address and the transfer amount.
2. The request enters the network and is transmitted to the computers of miners or validators.
3. Network participants automatically scan the transaction: do they have enough funds, and does the transaction violate the rules?
4. The confirmed transaction is added to a block, which is then sent to the blockchain. After that, the transfer is considered complete.

Commissions and Transaction Confirmation

A small fee is charged when you send cryptocurrency. It is credited to the balance of miners or validators and is part of their earnings. The amount of the fee is not fixed and can be adjusted independently, depending on the load on the blockchain. The more the user pays for their transfer, the faster it will be processed.

Types of Digital Assets

There are several classifications of cryptocurrencies. Technically, they are divided into:

• Coins. These are digital assets that operate on their own platform. They include Bitcoin, Ethereum, BNB, Tron, Polkadot, and others. 
• Tokens. These are cryptocurrencies created on the basis of existing blockchains. Examples: Shiba Inu, Tether, USD Coin, Chainlink. 

The first and most famous cryptocurrency is Bitcoin — the history of cryptocurrencies began with it. All other tokens and coins that appeared after it are commonly referred to as altcoins. 

There is also a classification of cryptocurrencies by purpose:

• Stablecoins are stable cryptocurrencies whose value is pegged to physical assets.
• NFT tokens are unique digital assets that confirm ownership of a specific digital object.
• Governance tokens — give owners the opportunity to participate in voting and make decisions within crypto projects.

How Does Crypto Differ from Regular Money?

Simply put, the main difference between cryptocurrency and fiat money is the principle of system management.

Traditional currencies, such as the dollar or euro, are issued and controlled by the state and central banks. They can exist in the form of cash or in bank accounts. At the same time, the amount of such money can increase, which eventually leads to inflation.

Cryptocurrency works differently. It is not controlled by a single country or organization. Transfers are made directly between users via blockchain without intermediaries.

Another difference is control over funds. Money in a bank account is actually stored at a financial institution, while cryptocurrency is stored on the blockchain, and only the owner can control it using the private key from their wallet.

Also, many cryptocurrencies have a limited number of coins. This means they cannot be issued indefinitely, like regular money, reducing the risk of devaluation.

Main Ways to Use Cryptocurrency

Digital assets are used for various online financial transactions:

• Some companies and services accept tokens and coins as a form of payment.
• Many people buy cryptocurrency in anticipation of its value increasing and hold it as a long-term asset.
• It is a way to send funds anywhere in the world without banks and with relatively low fees.
• Users buy and sell different coins and tokens on exchanges, trying to profit from changes in their prices.
• Some cryptocurrencies are used in DeFi platforms, smart contracts, and other blockchain applications.

What Backs Crypto, and How Is Its Price Formed?

Unlike fiat currency, cryptocurrency is not backed by gold or government reserves. Its value is determined by the market, just as the prices of stocks, currencies, and other assets are.

If interest in a particular cryptocurrency grows and it is actively bought, the price rises. When demand falls, and investors start selling coins, the value usually decreases.

The price is also influenced by trading volume, liquidity, and news surrounding the project. For example, technological updates, the launch of new services, or support from large companies can increase interest in a cryptocurrency.

In addition, major investors, often referred to as "whales," influence the market. Their large transactions can cause price fluctuations.

How Secure Is Cryptocurrency?

Digital money and transactions with it have reliable technical protection. In the previous chapters, we explained how cryptocurrency works in simple terms and that transaction data cannot be forged or altered.

However, security depends not only on technology but also on user actions. For example, storing funds on a crypto exchange can be risky due to the threat of hacking. To increase security, many users prefer hardware wallets, where private keys are stored offline and are less vulnerable to hacking.

It is also important to note that the crypto market is not yet regulated in all countries, so the responsibility for the safety of funds lies mainly with the owner. 

Top 5 Cryptocurrencies by Market Capitalization

There are thousands of different coins on the crypto market, but only a few projects occupy leading positions in terms of market capitalization — the total value of all coins issued. Let's take a look at the five most famous cryptocurrencies:

Bitcoin (BTC)

This coin is often referred to as "digital gold" because many investors use it as a store of value. Bitcoin is highly liquid and is supported by virtually all crypto exchanges and services..

Ethereum (ETH)

This is the second-largest cryptocurrency by market capitalization and, at the same time, a major blockchain platform. It is used not only for transfers but also for creating DApps, smart contracts, and various crypto services. Thanks to this, Ethereum occupies an important place in the cryptocurrency ecosystem.

Tether (USDT)

Unlike many cryptocurrencies, the value of the USDT stablecoin remains almost unchanged because it is pegged to the US dollar. Cryptocurrency is widely used on crypto exchanges for trading, storing funds, and transferring funds between platforms.

Binance Coin (BNB)

It is the cryptocurrency of the Binance ecosystem. Initially, it was created to pay commissions on the exchange, but over time, it began to be used in other services within the ecosystem: in the BNB Chain blockchain, DeFi projects, and various crypto applications.

Ripple (XRP)

This cryptocurrency was created with the aim of speeding up international transfers and reducing their cost. XRP is used in payment systems and can be used by banks and financial companies.

How Can Beginners Buy Cryptocurrency?

Today, there are several ways to buy cryptocurrency. These include crypto exchanges, P2P platforms, and crypto ATMs. However, such services may seem complicated to beginners: you need to register, understand the interface, and understand how orders and commissions work.

Therefore, many users choose crypto exchanges — an easier, faster way to buy digital assets. Just select the desired currency and specify the amount and payment details.

For example, the ObmenAT24 service allows you to buy cryptocurrency at a favorable rate and with minimal commissions. Users can make an exchange online by paying for the transaction with a bank card or electronic payment systems, or offline with cash. This format makes buying cryptocurrency convenient, even for those just getting started in the crypto market.

What Is the Future of Cryptocurrency?

Today, cryptocurrencies are already actively used for investments, international transfers, and working with various digital services. At the same time, blockchain technology is developing, with new projects and platforms emerging. DeFi and NFTs are opening new opportunities for working online.

However, the development of the cryptocurrency market largely depends on regulation. Many countries are already developing rules for working with cryptocurrencies. These decisions will determine how digital assets will be used in the future.
