1. Introduction: Why you should understand Bitcoin
In a world where cash is being used less and less, Bitcoin offers a digital, decentralized, and innovative alternative. For many, it may seem complicated, but in reality, Bitcoin is a simple idea with massive impact: money you control — not a bank or a government.
2. What is Bitcoin? A simple explanation
Bitcoin is a digital currency (cryptocurrency) that allows people to send money directly to each other, without intermediaries like banks.
📌 In short:
- It’s 100% digital — no physical form.
- You can send it anywhere in the world, anytime.
- It’s completely decentralized — not controlled by any government or company.
3. Who invented Bitcoin and why?
Bitcoin was launched in 2009 by a person (or group) under the pseudonym Satoshi Nakamoto. The main motivation? To create money that can’t be controlled or devalued by central authorities, like what happened during the 2008 financial crisis.
4. How does Bitcoin work?
Bitcoin runs on a technology called blockchain — a public digital ledger that records every transaction ever made.
📌 When you send Bitcoin:
- The transaction is verified by computers in the network (called miners).
- It’s added to a new block of transactions.
- That block is linked to the previous ones — creating a blockchain.
5. What is blockchain and why is it important?
Blockchain is the technology behind Bitcoin. It’s a distributed ledger — stored on thousands of computers around the world. It cannot be altered, making it extremely secure.
🔐 Main benefits:
- Tamper-proof
- Transparent and public
- No central authority
6. How is Bitcoin different from traditional money?

8. Is Bitcoin legal in your country?
In most countries, including Romania, Bitcoin is legal, but treated as a digital asset. Profits from crypto trading must be declared and taxed.
📌 Crypto tax in Romania (2025): 10% on profits
