Bitcoin continues to dominate the digital asset landscape as both a revolutionary form of money and a compelling long-term investment. With growing adoption across Europe and beyond, understanding its value, utility, and market dynamics has never been more important. This guide explores everything you need to know about Bitcoin—from how it works and why it was created, to how you can invest in it today.
Why Was Bitcoin Created?
Bitcoin emerged in 2008 during the global financial crisis, a time when trust in centralized banking systems reached an all-time low. Its anonymous creator, Satoshi Nakamoto, introduced Bitcoin as a response to the flaws of traditional finance—particularly the risks of monetary devaluation, lack of transparency, and overreliance on intermediaries.
Designed as a decentralized digital currency, Bitcoin enables peer-to-peer transactions without the need for banks or payment processors. This reduces transaction costs and processing times significantly. Unlike fiat currencies, which central banks can print indefinitely, Bitcoin has a hard cap of 21 million coins. This scarcity is engineered to prevent inflation and preserve value over time, making Bitcoin a modern alternative to gold—a digital store of value.

What Is Bitcoin Used For?
Bitcoin serves two primary functions: digital currency and store of value.
As a digital currency, Bitcoin allows fast, secure, borderless payments. Whether sending money internationally or paying for goods online, Bitcoin cuts out middlemen and reduces fees compared to traditional banking systems. It’s especially valuable in regions with strict capital controls or unstable national currencies.
As a store of value, Bitcoin is often referred to as “digital gold.” Its fixed supply and growing adoption make it an attractive hedge against inflation. Investors increasingly include Bitcoin in diversified portfolios, not just for potential appreciation but also as protection against macroeconomic uncertainty.
Moreover, Bitcoin's blockchain provides transparent, immutable transaction records—enhancing security and trust in financial interactions.
Can You Buy Fractions of Bitcoin?
Yes—you don’t need to buy a full Bitcoin to invest. Bitcoin is divisible up to eight decimal places, with the smallest unit called a Satoshi (0.00000001 BTC). This high level of divisibility makes Bitcoin accessible to anyone, regardless of budget.
For example:
- 0.001 BTC = 1 millibitcoin (mBTC)
- 0.000001 BTC = 1 microbitcoin (μBTC)
- 0.00000001 BTC = 1 Satoshi
This means you can start investing with as little as a few euros or dollars. Fractional ownership opens the door for widespread participation in the Bitcoin economy.
Frequently Asked Questions
Q: How much is one Bitcoin worth today?
A: The price of Bitcoin fluctuates constantly based on global supply and demand. You can check real-time BTC prices in EUR and USD using live tracking tools on major crypto platforms.
Q: Is Bitcoin backed by anything physical?
A: No, Bitcoin isn’t backed by physical assets like gold. Instead, its value comes from scarcity, decentralization, security, network effect, and increasing institutional and retail adoption.
Q: Can Bitcoin be converted to cash?
A: Yes. You can sell Bitcoin on regulated exchanges and withdraw funds directly to your bank account in euros, dollars, or other fiat currencies.
How Is the Price of Bitcoin Determined?
The price of Bitcoin is driven entirely by market supply and demand—just like stocks or commodities. When more people want to buy than sell, the price rises. When selling pressure exceeds buying interest, the price drops.
Several factors influence this balance:
- Macroeconomic trends: Inflation rates, interest rate changes, and geopolitical instability often drive investors toward Bitcoin.
- Regulatory news: Positive regulation boosts confidence; restrictive policies may cause short-term dips.
- Adoption milestones: Major companies accepting Bitcoin or institutions adding it to their balance sheets increase demand.
- Halving events: Approximately every four years, the number of new Bitcoins created per block is cut in half, reducing supply growth and historically leading to bull markets.
This dynamic pricing model ensures that Bitcoin remains responsive to global economic sentiment while maintaining independence from any single government or entity.
Is Bitcoin Legal?
In the European Union, Bitcoin is legal and regulated under frameworks designed to prevent money laundering and protect consumers. The EU’s MiCA (Markets in Crypto-Assets) regulation provides clear rules for crypto service providers, exchanges, and issuers—making it safer and easier for individuals to use and invest in digital assets.
Outside Europe, legality varies:
- Countries like the U.S., Canada, Japan, and Singapore recognize Bitcoin as a legitimate asset class.
- Some nations have imposed restrictions or outright bans (e.g., China), though enforcement varies.
Always verify local regulations before buying or using Bitcoin in your country.

What Sets Bitcoin Apart From Other Cryptocurrencies?
While thousands of alternative cryptocurrencies (altcoins) exist, Bitcoin remains unique due to several core attributes:
- Decentralization: No single entity controls the network. It operates on a distributed consensus mechanism secured by miners worldwide.
- Security: As the longest-running blockchain with the highest hash rate, Bitcoin is the most secure and resilient network.
- Network effect: With the largest user base, developer community, and institutional support, no altcoin matches Bitcoin’s influence.
- Censorship resistance: Transactions cannot be blocked or reversed by governments or corporations.
- Predictable monetary policy: The emission schedule is fixed—no surprises or sudden inflation.
Many altcoins promise innovation but rely on centralized teams or fail to deliver real-world utility. Bitcoin evolves conservatively through broad consensus, prioritizing stability over rapid change.
What Is Bitcoin’s Environmental Impact?
One common criticism of Bitcoin is its energy consumption. However, recent data paints a more nuanced picture:
- Over 50% of Bitcoin mining uses renewable energy, according to the Cambridge Centre for Alternative Finance.
- Miners are incentivized to use low-cost energy sources—often surplus hydroelectric, wind, or solar power that would otherwise go unused.
- Some operations repurpose waste heat from mining rigs for district heating or greenhouse agriculture—an emerging part of the circular economy.
Rather than being an environmental burden, Bitcoin is accelerating investment in clean energy infrastructure by creating demand for stranded or underutilized renewable resources.
Frequently Asked Questions
Q: Can I save money automatically in Bitcoin?
A: Yes. Many platforms offer automated recurring purchases—allowing you to invest small amounts regularly without manual effort.
Q: What is Dollar Cost Averaging (DCA)?
A: DCA involves investing a fixed amount at regular intervals (e.g., weekly or monthly). This strategy reduces the impact of volatility by averaging your purchase price over time—ideal for long-term investors.
Q: Where should I store my Bitcoin safely?
A: For maximum security, use a hardware wallet (cold storage). For convenience, regulated apps with strong encryption offer reliable custody solutions.
