Asking “What is money for?” may sound strange, but the answer has shaped human civilization for thousands of years. People have always needed a universal measure of value for trade – gold bars, shells, salt, even bottles of alcohol once played that role. Over time, coins and paper money replaced them. With the rise of the internet, traditional currencies evolved into digital forms. Dollars, euros, and yuan didn’t disappear – they just moved to plastic cards, online accounts, and mobile apps.
It might seem like progress has reached perfection: fast payments, secure banking, and total convenience. Yet modern financial systems remain vulnerable. Hackers can still exploit weaknesses, but an even bigger problem is money printing. Governments can issue unlimited currency at any time — a process that fuels inflation. To stabilize the economy, they print even more. The result is a vicious cycle. Add to that high intermediary fees charged by banks, and you get a financial system that clearly needs modernization.
And then a new digital currency, Bitcoin, suddenly appears and at first slowly, then more and more rapidly, begins to penetrate the global financial system. In the first few years, many simply brushed it off, saying Bitcoin was just another pyramid scheme about to burst, leaving naive enthusiasts who believed in some mythical Satoshi Nakamoto with nothing. Who is he, has anyone even seen him? That all sounds logical – if you ignore a few circumstances.
In this overview, we will explain in simple terms what Bitcoin is and why BTC is one form of the money of the future, intended to replace fiat currencies.

What Is Bitcoin
That’s where Bitcoin comes in – a digital payment network that uses cryptocurrency and peer-to-peer (P2P) technology to create and manage transactions without banks. The system is open-source and decentralized: new Bitcoins are generated and verified by participants worldwide. This innovation emerged during a global financial crisis, when public trust in banks was at an all-time low.
The term “cryptocurrency” can be decoded roughly as follows: cryptocurrencies are digital assets that are created and controlled by a system based on the method of asymmetric cryptography. A cryptocurrency network is fully decentralized, meaning it has no single governing body and is not subject to external regulators. The technology used to create such a cryptosystem is the blockchain. All information within the network is presented in open form, and its immutability is guaranteed by cryptographic elements.
A blockchain is a continuous chain of blocks in which information about all transactions is encrypted. A new block is formed after one of the network nodes finds its digital signature. Essentially, each block of a crypto network can be compared to a separate chapter of an accounting book that contains information about the previous chapter and all the financial transactions included in it. The cumulative set of data recorded in a strictly defined sequence is the blockchain. The integrity of its structure is ensured by cryptographic protection.
Bitcoin itself is both the system and its currency – the unit of account. It has no physical form like coins or notes; it exists as digital code stored on the blockchain. You can’t hold Bitcoin in your hand, but you can store and send it globally within seconds. Unlike traditional money, BTC cannot be counterfeited, frozen, or printed at will.
- Counterfeited;
- Banned;
- Destroyed.
You can pay with such coins anywhere and anytime. They don’t wear out or tear like paper bills, but if you are careless and reckless they can be stolen if someone gains possession of your private key, or you yourself may lose the access code to your assets. For convenience, one Bitcoin is divided into 10,000,000 parts called satoshi.
Why Bitcoin Is Needed
Security is Bitcoin’s main strength. Despite anti-counterfeit efforts, around half of all cash in circulation is estimated to be fake or altered. Bank servers can be hacked, and central institutions can manipulate monetary supply. Bitcoin removes that risk – transactions are verified by cryptographic algorithms and the global community of miners.
With cryptocurrency, such manipulations are impossible, which puts it a step above traditional money. Moreover, the way the Bitcoin network works allows payment anonymity to be preserved. The governments of 99 countries have officially permitted the use of BTC as a means of payment. The cryptocurrency is popular in such developed countries as:
- Japan;
- USA;
- Canada;
- Germany;
- Denmark;
- Sweden;
- Australia;
- Singapore.
There you can find special Bitcoin ATMs for conducting operations, and in Singapore you can even buy a Bitcoin “banknote.” Of course, it’s not paper cryptocurrency, but a “cold wallet” that holds a certain amount of virtual coins. After paying, the customer receives the access keys to the vault preserved in paper form.
Bitcoin is used to preserve wealth. People who bought the first cryptocurrency in the early years of its existence secured themselves a comfortable life. Just 9 months ago, during a market downturn, Bitcoin could be bought for $3,200, and now 1 BTC is $35,000, while at its peak the price reached $66,000. One Norwegian citizen bought 5,000 BTC for $27 and forgot about his capital for several years, and when he learned that the cryptocurrency had soared in price, he couldn’t find the private key to his Bitcoin wallet for a long time. But eventually he did; at that time 5,000 BTC were worth $880,000. If he didn’t immediately convert them to fiat, then today his fortune would be equivalent to $175,000,000. And most members of the crypto community are sure this is far from the limit. According to the boldest forecasts, the price of one coin of digital gold will sooner or later rise to one million U.S. dollars. Perhaps that’s an exaggeration, but it’s quite possible that under such circumstances in two or three years 1 BTC will cost $100,000. So the peak of the crypto-fever is still ahead.
Crypto traders make fortunes by playing the fluctuations in price and the differences in coin prices across trading platforms. Bitcoin is often compared to gold: the number of crypto coins and the reserves of the noble metal are limited, and both assets can easily be exchanged for traditional money.
Where Do Coins Come From
A cryptocurrency is created by solving complex mathematical problems using computing power. Initially, mining was done on CPUs, then GPUs, and now requires specialized ASIC machines. Each solved algorithm generates a block – and miners are rewarded with new coins (currently 6.25 BTC per block). The Bitcoin network verifies every block using a peer-to-peer structure, ensuring there’s no central authority and all participants are equal.
Mining machines:
- Are quite expensive ($2,000–$6,000);
- Consume a lot of electricity;
- Are very noisy;
- Require special skills for setup and operation.
Decentralization
All nodes are independent and cannot influence each other, and each stores a full copy of the blockchain. Even if some of them shut down, this does not affect the operation of the system. To restore the network in the event of some large-scale catastrophe, a single preserved copy is sufficient.
According to the online publication Forklog, the Bitcoin network has 11,619 full nodes, each serving as a custodian of a full copy of the blockchain. And judging by data from the blockchain explorer https://www.blockchain.com/explorer, there are already more than 38 million active addresses. In the beginning, the Bitcoin network consisted of two computers: one belonged to Satoshi Nakamoto himself, the other to Hal Finney. By the way, let’s take a closer look at what a blockchain explorer is.
Block Explorer
When developing a new crypto project, a dedicated block explorer is always created; without it, the operation of a distributed payment network is not possible. Such a service is very necessary, but if you constantly work with several digital currencies at once and regularly monitor the state of a given blockchain, you would prefer a universal search engine.
It is much more convenient to move from one network to another with a single mouse click than to store a pile of links and open a new window each time. Of course, an engine for searching information across all 7,784 distributed payment networks has not yet been created. But there is a universal solution that supports 17 top cryptocurrencies as well as ERC-20, Omni, and Laer tokens. The resource is called Blockchair; with it you can track transactions and obtain other information, such as text messages, PDF receipts, and cryptocurrency price charts for:
- Bitcoin;
- Bitcoin Cash;
- Ethereum;
- EOS;
- Ripple;
- Litecoin;
- Monero;
- Dash;
- Zcash;
- Dogecoin;
- Stellar;
- Tezos;
- Cardano;
- Bitcoin SV;
- Bitcoin ABC;
- Mixin;
- Groestlcoin.
The official website of this search and analytics service is at https://blockchair.com.
The interface is available in seven European languages. Developers have access to an API with support for filtering, sorting, and aggregating information. The Blockchair Feed option allows you to read texts placed on the Bitcoin, Bitcoin Cash, and Ethereum blockchains on the fly. It also displays messages from the decentralized social networks Blockpress.com and Memo.cash.
If you don’t want to look for a bookmark every time, add the “Release Monitor” app to your Google browser to use a wide range of Blockchair’s universal block explorer services via the search bar. The Blockchair team is constantly working on updates and expanding the service’s capabilities. If necessary, you can contact support at info@blockchair.com or via social networks Facebook, Twitter, LinkedIn, Telegram.
The project developers’ main goal is to make the resource a Google-like search engine for cryptocurrencies, and they are successfully implementing their plans. You can see links to Blockchair information on platforms like Coinbase, HitBTC, CoinMarketCap, CoinGecko, and other crypto-industry sites.
What Backs Bitcoin
Bitcoin does not have direct backing by goods, gold, or fiat money, unlike stablecoins. However, major business structures are interested in the development of an alternative payment system, such as:
- Dell;
- AppStore;
- Microsoft;
- Amazon;
- RE/MAX;
- Victoria’s Secret;
- Tesla;
- Reddit.
And this is far from a complete list of companies supporting cryptocurrency. On the Bitcoin network, payments totaling the equivalent of $94,000,000 are executed on average per day, and the network’s computational power is 99.4 Ehash. The best backing for Bitcoin is its unique properties:
- Decentralization;
- Anonymity;
- Transparency;
- Cryptographic protection;
- Low fees.
According to the blockchain explorer blockchain.com, the fee for processing transactions is only 0.619% of the total turnover of funds. In early September of last year, a transaction exceeding $1,000,000,000 was recorded on the blockchain—these are the kinds of large deals conducted in BTC.
Issuance
The issuance of a national currency is controlled by a country’s government, but physically the money supply is not limited by anything, and if desired, one can print as many dollars, pounds, as one wants. In total, there will only ever be 21 million BTC. This limit is hard-coded into Bitcoin’s protocol and cannot be changed. When the last coin is mined – expected around 2140 – new rewards will stop, but miners will continue earning from transaction fees.
How You Can Get Bitcoins
Bitcoin, like most cryptocurrencies, is generated through mining with specialized hardware. To do this, you purchase an application-specific integrated circuit (ASIC) designed exclusively for producing bitcoins and other SHA-256–based coins. While the majority of BTC mining happens in large-scale data centers, those with suitable conditions can set up an ASIC at home. Once it’s running, the mined bitcoins will automatically go to your wallet.
- An ASIC cannot be kept in an apartment or a private house due to the loud noise produced by the cooling system fans. True, some enthusiasts make sound-absorbing boxes or convert their devices to liquid cooling, but this requires additional costs and is not suitable for every user. Usually ASICs are placed in a separate room, such as a garage, or the services of specialized “mining hotels” are used.
- You won’t be able to mine bitcoins on graphics cards, but you can mine other coins and then exchange them for BTC, as well as rent out your hashrate on services like NiceHash or Mining Rig Rentals and get paid in bitcoin.
- You can collect a few satoshis by regularly visiting bitcoin faucets—websites where users are credited with a small amount of cryptocurrency for completing simple tasks. You won’t be able to gather a whole bitcoin, but such sites are great for getting acquainted with cryptocurrency.
- There are freelance exchanges, for example Xbtfreelancer or Cryptogrind, where performers are paid in bitcoin.
- And finally, you can always buy Bitcoin for ordinary currency. We’ll explain how that works in a separate section.
What You Can Buy With Bitcoin
BTC can not only be easily exchanged for other assets – it can be used as a payment method in many developed countries. Japan holds the lead. In the Land of the Rising Sun, 260,000 retail stores accept payment in bitcoin.
- Virtual assets are suitable for buying groceries, transportation, real estate, an airline ticket or a hotel room. Some educational institutions accept tuition payments in cryptocurrency. The Republican Party of the United States accepts donations for its development in BTC. Cryptocurrency is used by Virgin Galactic, a company operating in the field of space tourism.
- News regularly appears about a bar or restaurant in one country or another opening with support for Bitcoin payments. In Argentina, you can pay for public transportation, utilities, and taxes with cryptocurrency.
- The Spendabit search engine will help you find platforms and stores that sell their goods for Bitcoin. Using Spendabit is simple: type what you need into the search bar and get a list of sellers.
To search for goods for cryptocurrency on the decentralized platform OpenBazaar, the Duosearch search engine is used. You can also install the Haven Private Shopping app to search for goods on OpenBazaar via your smartphone. People buy luxury goods, villas, yachts, and cars for BTC. Some financial experts believe that in the future Bitcoin will become a digital standard of value. That is, BTC will be held instead of a gold reserve, which is very convenient and practical, while cheaper alternative coins will be used for everyday settlements. Then owning bitcoin will become a status symbol—hurry to acquire digital gold before its price soars to the skies.
Still, acquiring an entire bitcoin remains out of reach for many people – even in wealthier nations. Fortunately, you don’t need to buy a whole BTC at once. You can start with a small portion, such as one-tenth or even one-hundredth of a coin, and gradually increase your holdings.
How to Buy Bitcoin
On the web you will find cryptocurrency exchanges where you can buy Bitcoin for fiat money. For residents of the CIS countries, the following trading platforms are suitable:
- Binance;
- Exmo;
- Yobit;
- Huobi.
Binance clients can buy Bitcoin for rubles in four ways:
- With a credit or debit card directly from the exchange administration;
- Directly from other traders in the P2P trading section;
- From a fiat balance on the spot market;
- Through built-in exchangers from partner companies.
Each option has its pros and cons and you should choose based on your preferred payment method. If you need to buy quickly and you’re paying by card, choose the first option.
There are special Bitcoin ATMs with which you can buy cryptocurrency for cash, but you won’t find them everywhere.
How to Store Coins Correctly
It’s important to note that cryptocurrencies themselves are stored on the blockchain, not inside your wallet. What you actually keep is the private key that enables transactions from your Bitcoin address. Your wallet app simply shows your balance and transaction history. The golden rule of crypto security is to store your private key offline and never disclose it to anyone.
A wallet can be:
- A program installed on a hard drive;
- A mobile app;
- An online service;
- A hardware safe for storing private keys electronically;
- A sheet of paper with the printed public and private keys generated by a special online resource.
To receive funds on a paper wallet, you only need to share your public address with the sender. However, to send funds yourself, you’ll have to use an online wallet interface.
The safest option for storage is a hardware wallet – a USB-like device with a small screen that prevents unauthorized access. It allows you to manage your assets securely and execute transactions safely. The most reputable hardware wallet brands include Ledger and Trezor.
Wallets installed on a PC are divided into “full” (requiring the entire blockchain to be downloaded) and “light” (synchronized with a remote server). Mobile wallets are very convenient for paying with bitcoin at retail outlets that accept cryptocurrency. But most often users prefer working with online services that do not require installing additional software. The most popular include:
- Trust Wallet;
- Blockchain;
- Coinbase;
- Circle;
- Xapo.
However, for long-term storage of large sums in cryptocurrency, it is recommended to purchase a hardware safe. This device is a mini-computer made in the form of a large flash drive with buttons and a display.
Its sole purpose is to store private keys that grant access to the blockchain. To perform financial transactions, a hardware safe is connected to a regular PC, but even if the computer is infected with viruses, no hacker will gain access to your private keys.
Conclusion
It’s impossible to fully cover Bitcoin in a single article – the topic deserves an entire book. But now you have a solid introduction to the first cryptocurrency. If the subject captures your interest, you can explore more materials on our site. Beyond Bitcoin, there are other digital currencies vying for similar recognition, as well as entirely different systems like Ethereum. Bitcoin is far more than just an alternative payment network – its invention marked the dawn of a new digital era and gave rise to the cyber-economy.
Over the past two years, many unique projects have been launched, a whole sector of decentralized financial services has emerged, and now you can earn cryptocurrency by depositing digital assets into liquidity pools. The blockchain industry has already become an integral part of the global financial system.
If you compare the monetary characteristics of traditional currency, gold, and bitcoin, the advantages of the virtual coin become obvious. Sooner or later – preferably sooner – all regulatory issues regarding the use of cryptocurrency will be resolved, and then the world will change for the better. Start using cryptocurrency today. Good luck!
