Bitcoin (BTC) is the world's first and most valuable cryptocurrency. As of 2026, it remains the most widely adopted digital asset and is available on virtually every major exchange. This guide walks you through the process step by step.
What You'll Need
- A valid email address
- A government-issued ID (for exchanges that require KYC)
- A payment method: bank transfer, debit card, or existing crypto
- A secure password manager (strongly recommended)
Step 1: Choose a Crypto Exchange
Your first step is picking a trusted exchange. We recommend Kraken — one of the oldest and most trusted exchanges in crypto, founded in 2011 and available in 190+ countries including the US and EU.
- Deep BTC liquidity — among the highest BTC/USD volume globally
- Regulated and licensed — US, EU, and UK compliant
- Kraken Earn — earn yield on BTC and other assets
- Fees: 0.16% maker / 0.26% taker (lower tiers with volume)
Step 2: Create Your Account
- Visit the exchange website using one of the links above.
- Click Sign Up or Register.
- Enter your email address and create a strong, unique password.
- Verify your email by clicking the link sent to your inbox.
- Enable two-factor authentication (2FA) — use an authenticator app, not SMS.
Security tip: Never use the same password as another account. Enable 2FA immediately after registration. Use Google Authenticator or Authy.
Step 3: Complete Identity Verification (KYC)
Most regulated exchanges require identity verification before you can deposit fiat or make large trades. This usually involves:
- Uploading a photo of your passport or driver's licence.
- Taking a selfie for facial verification.
- Waiting for approval (usually instant to a few hours).
KYC is required on Kraken but the process is straightforward and typically completes within minutes.
Step 4: Deposit Funds
Once verified, deposit money to buy Bitcoin:
- Bank Transfer (SEPA/ACH): Lowest fees, takes 1–3 business days.
- Debit/Credit Card: Instant but typically 1.5–3% fee.
- Crypto Deposit: Transfer existing crypto from another wallet or exchange.
Navigate to Wallet → Deposit on your chosen exchange and follow the instructions for your preferred method.
Step 5: Buy Bitcoin
- Go to the Markets or Trade section.
- Search for BTC/USDT or BTC/USD.
- Choose Market Order (buy at current price) or Limit Order (set your preferred price).
- Enter the amount in USD/USDT you want to spend.
- Click Buy BTC and confirm the transaction.
Beginner tip: Start with a Market Order for simplicity. You'll buy at the current market price and receive your BTC immediately.
Step 6: Secure Your Bitcoin
For small amounts you plan to trade, keeping BTC on the exchange is fine. For long-term holding:
- Software wallet: Trust Wallet or Exodus (free, easy, good for beginners).
- Hardware wallet: Ledger or Trezor (most secure for large amounts).
