Bitcoin has become a household name, sparking debates worldwide. While some champion it as the future of money, others remain skeptical. What exactly is Bitcoin? How can you buy it? What are its pros and cons?
Explaining every detail of Bitcoin’s functionality could fill volumes. Its underlying technology involves complex cryptography, mining, and decentralized systems. However, we can simplify the basics: what Bitcoin is, how it works, and where to acquire it.
Key Takeaways
- Bitcoin is a decentralized digital currency created, held, and exchanged electronically.
- Transactions are broadcast to a peer-to-peer network, validated by miners, and recorded on the blockchain—a public ledger.
- Bitcoin’s high volatility leads to frequent price fluctuations, offering both opportunities and risks.
- Purchase Bitcoin through exchanges (e.g., Coinbase, Binance) or brokers (e.g., eToro, XTB) as a speculative asset.
- This guide covers essential variables for beginners looking to buy or trade Bitcoin.
What Is Bitcoin?
Bitcoin (BTC) is the first and most widely adopted cryptocurrency, operating without central authority. Unlike traditional fiat currencies (e.g., euros), Bitcoin has a fixed supply cap of 21 million coins, expected to be fully mined by 2140. Its decentralized nature means no government or bank controls it.
The first recorded Bitcoin transaction was the iconic Bitcoin Pizza Day, where 10,000 BTC bought two pizzas (worth ~$0.40 at the time). Today, Bitcoin is both a store of value and a medium for transactions.

How Bitcoin Works
Bitcoin transactions rely on blockchain technology:
- Transactions are grouped into blocks.
- Miners compete to solve cryptographic puzzles, validating blocks.
- Verified blocks join the blockchain, and miners earn new BTC as rewards.
- The decentralized network ensures transparency and security.
Key features:
- Pseudonymity: Transactions link to wallet addresses, not identities.
- Irreversibility: Once confirmed, transactions can’t be undone.
- Low fees: Typically cheaper than traditional bank transfers.
Bitcoin Price Volatility and Charts
Bitcoin’s price is highly volatile, driven by market demand, regulations, and macroeconomic trends. To track its value:
- Check real-time charts on platforms like CoinGecko or CoinDesk.
- Analyze historical trends (hourly, daily, yearly) to identify patterns.
Example: In 2021, BTC surged to ~$69,000 before dropping 50%+ in 2022. Such swings make it critical to assess risk tolerance before investing.
