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

For instant, non-custodial swaps, we recommend ChangeNOW: swap 1,500+ cryptocurrencies across 110 blockchains with no account or KYC required.

• Deep BTC liquidity: among the highest BTC/USD volume globally
• Regulated and licensed: US, EU, and UK compliant
• Fees: 0.16% maker / 0.26% taker (lower tiers with volume)

Step 2: Create Your Account

1. Visit the exchange website using one of the links above.
2. Click Sign Up or Register.
3. Enter your email address and create a strong, unique password.
4. Verify your email by clicking the link sent to your inbox.
5. Enable two-factor authentication (2FA). Use an authenticator app, not SMS.

Step 3: Complete Identity Verification (KYC)

Most regulated exchanges require identity verification before you can deposit fiat or make large trades. This usually involves:

1. Uploading a photo of your passport or driver's licence.
2. Taking a selfie for facial verification.
3. Waiting for approval (usually instant to a few hours).

If using a regulated exchange, KYC is required but the process is straightforward and typically completes within minutes. ChangeNOW requires no KYC at all.

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

1. Go to the Markets or Trade section.
2. Search for BTC/USDT or BTC/USD.
3. Choose Market Order (buy at current price) or Limit Order (set your preferred price).
4. Enter the amount in USD/USDT you want to spend.
5. Click Buy BTC and confirm the transaction.

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).
