What is Bitcoin?
An independent e-currency regulated by encryption for creation and verification of transactions
Bitcoin is a decentralized, deflationary digital currency that operates independently of any central bank or government. Its functioning relies entirely on blockchain technology—a distributed protocol that uses cryptography and complex mathematical functions to verify transactions, store data, and create new currency units.
The blockchain acts as an incorruptible digital “accountant” operating through a network of nodes (computers) worldwide. Unlike traditional systems, the blockchain is nearly impossible to compromise, as each node holds a complete transaction history and actively participates in network validation.
Brief History
A vision for a fairer monetary system
Bitcoin was introduced in 2009 by an anonymous programmer (or group) under the pseudonym Satoshi Nakamoto, with the idea of creating a decentralized and transparent system for value exchange. Out of the maximum 21 million bitcoins that can ever exist, more than 19.5 million have been mined to date, while it is estimated that a few million are permanently lost.
Over time, Bitcoin has become a symbol of economic freedom and resistance to inflation. Initially used by enthusiasts and crypto pioneers, it is now increasingly accepted by banks, investment funds, and companies as a legitimate asset.
Why is Bitcoin so valuable?
"Digital Gold"
Bitcoin has risen from its first cents to a new all-time high of 111,814 USD, reached on May 22, 2025. Despite frequent price fluctuations, Bitcoin retains the status of “digital gold” due to its limited supply, global demand, and increasing technological and energy costs associated with mining.
In January 2024, the first spot Bitcoin ETFs were launched in the US (e.g., iShares Bitcoin Trust – IBIT and Fidelity Wise Origin), attracting over 1.5 billion USD in their first weekend alone. Institutional investors such as BlackRock, MicroStrategy, and PayPal have significantly increased their Bitcoin exposure, accelerating market legitimization and stability.
Should you invest in Bitcoin and other cryptocurrencies?
Ethereum, Solana, Litecoin, Ripple, Dogecoin, ADA, AVAX...
Cryptocurrencies remain one of the most volatile forms of investment. After a significant boom in 2020–2021, the market has undergone major corrections. However, Bitcoin and Ethereum remain among the most stable in the long term, while increasing attention is given to projects in DeFi (decentralized finance), NFTs, and tokenization of real-world assets.
Still, it is important to invest responsibly. No one can predict market movements with certainty. Invest only what you are willing to lose, and think long term.
How to buy Bitcoin?
Today, Bitcoin can be bought quickly and easily through online exchanges. Besides classic credit card purchases, many platforms now accept bank transfers, PayPal, and even Google/Apple Pay. Buying via physical crypto ATMs is also possible in major cities. The most popular platforms for beginners are:
- CEX.IO – a reliable and affordable exchange supporting cards and bank transfers.
- Binance.com – the largest and most popular crypto exchange with a wide range of coins and tools.
- Ledger Wallet – the best-known hardware wallet for safely storing Bitcoin and other cryptocurrencies.
- Youtube – What is Bitcoin? – a short educational video explanation (in English).
*Risk Notice
Cryptocurrencies are risky assets. While they can bring potentially high returns, they are also subject to large price swings. It is important to use security measures like 2FA, hardware wallets, and carefully safeguard private keys.
Transactions are irreversible, and the market is still insufficiently regulated. Before investing, inform yourself from reliable sources and only use trusted platforms for buying and trading.
