Everything You Need to Get Started

We cover the full journey — from understanding Bitcoin to owning and earning it.

Chapter 1

What is Bitcoin?

Bitcoin is digital money — but unlike the money in your bank account, no government, bank, or company controls it. It's a currency that belongs to everyone and no one at the same time.

Created in 2009 by an anonymous person (or group) known as Satoshi Nakamoto, Bitcoin solved a problem that had stumped computer scientists for decades: how do you send digital money directly to someone without a middleman, and without them being able to copy it?

  • Decentralised — no central bank or authority controls it
  • Scarce — only 21 million BTC will ever exist
  • Borderless — send it anywhere in the world, 24/7
  • Transparent — all transactions are recorded on a public ledger
  • Censorship-resistant — no one can freeze or block your funds

Think of Bitcoin as digital gold — a store of value that can't be printed, inflated, or seized.

How Does Bitcoin Work?

Bitcoin runs on a technology called the blockchain — a public database shared across thousands of computers worldwide. Every transaction ever made is recorded on it, permanently and publicly.

When you send Bitcoin, the transaction is broadcast to the network, verified by miners, and added to the blockchain in a "block" — hence the name.

  • Blockchain: A chain of transaction records, stored by thousands of computers
  • Mining: Computers compete to validate transactions, earning BTC as a reward
  • Private Key: Your secret password — whoever holds it owns the Bitcoin
  • Public Key (Address): Like a bank account number — share it to receive BTC
  • Wallets: Software that stores your keys and manages your BTC

💡 Bitcoin transactions are irreversible. Always double-check the address before sending.

How to Buy Bitcoin

Buying Bitcoin has never been easier. You can own as little as a few euros worth — you don't need to buy a whole coin. Here's how to do it safely:

  • Choose a reputable, regulated exchange
  • Create an account and verify your identity (KYC is required by law)
  • Deposit funds via bank transfer or card
  • Buy BTC — even a small amount like €10 to start
  • Withdraw to your own wallet for safety (don't leave large amounts on exchanges)

We recommend OKX and Bybit — both are trusted, beginner-friendly, and offer low fees.

Chapter 4

How to Store Bitcoin Safely

The golden rule of Bitcoin: "Not your keys, not your coins." If you leave Bitcoin on an exchange and the exchange is hacked or goes bankrupt, your coins may be gone.

A Bitcoin wallet doesn't store your coins — it stores your private keys, which give you access to your Bitcoin on the blockchain.

  • Hot wallets are connected to the internet — convenient for small amounts
  • Cold wallets (hardware wallets) are offline — most secure for large amounts
  • Write your seed phrase on paper — never take a photo or store it online
  • For anything serious, a hardware wallet like Trezor is worth the investment

Reading Bitcoin Charts

You don't need to be a trader to understand price charts. A basic grasp of what's happening helps you make smarter decisions — like not panic-selling a dip.

TradingView is the most popular charting tool in the world, used by beginners and professionals alike. It's free to use and offers real-time Bitcoin price data.

  • Candlesticks: Each candle shows open, close, high, and low price for a period
  • Green candle: Price closed higher than it opened (bullish)
  • Red candle: Price closed lower than it opened (bearish)
  • Support: A price level where buying tends to occur
  • Resistance: A price level where selling tends to occur
  • Volume: How much BTC was traded — confirms the strength of moves

Common Questions

Frequently Asked Questions

Honest answers to the questions every beginner asks.

Yes — Bitcoin is legal in most countries including all EU member states, the US, UK, and Australia. Some countries restrict it (e.g. China), so check your local laws. In Bulgaria and across the EU, buying, holding, and selling Bitcoin is completely legal. You may owe capital gains tax when you sell at a profit.

No. Bitcoin is divisible into 100,000,000 units called Satoshis. You can buy as little as €5 worth. You own a fraction of a Bitcoin — it works exactly the same as owning a whole one, just smaller.

Yes — Bitcoin is volatile and the price can drop significantly in the short term. It has recovered from every major crash historically, but past performance doesn't guarantee future results. Only invest money you can afford to lose, and never invest out of fear of missing out (FOMO).

Bitcoin (BTC) was the first cryptocurrency and remains the largest by market cap. It has the most security, the longest track record, and the most adoption. Other cryptocurrencies ("altcoins") are separate projects with different purposes. Many beginners start with Bitcoin because it's the most established and understood.

Not fully. Bitcoin transactions are pseudonymous — they're publicly recorded on the blockchain under wallet addresses, not names. But exchanges require ID verification (KYC), so your identity is linked to your exchange account. Advanced techniques exist to improve privacy, but for most users Bitcoin is traceable.

If you lose access to your wallet, your seed phrase (12–24 words) is the master backup that restores it. If you also lose your seed phrase, the Bitcoin is permanently inaccessible — there is no customer support to recover it. This is why storing your seed phrase safely on paper is so important.

In Bulgaria, gains from selling Bitcoin are generally subject to a 10% capital gains tax. You should declare crypto gains in your annual tax return. Tax rules vary by country and change over time — always consult a local tax advisor for your specific situation. This is not tax advice.
