How to buy Bitcoin,
from $10.

Four things to know first

• You can buy a fraction. One Bitcoin is 100 million satoshis. The minimum order on the exchange is about 0.00001 BTC.
• It trades 24/7. Prices move all the time, and daily swings of 5% or more are normal.
• Only use spare money. Make sure a 50% drop wouldn't affect your life.
• Know who holds the keys. On an exchange, the exchange holds your coins. In your own wallet, you hold the keys.

From zero to BTC, step by step

1. Create your OKX account

Open the sign-up link. Referral code OK66688 fills in automatically. Register with email or phone.

2. Verify your identity

Upload a valid ID and complete the face check. This usually takes minutes and is required to deposit and trade.

3. Buy USDT

Use Buy Crypto with a card or bank transfer, or buy from a verified P2P merchant. Available methods depend on your region.

4. Buy Bitcoin

Open Trade → Spot, search BTC/USDT, enter an amount and place a market order. If you see “insufficient balance”, transfer USDT from your funding account to your trading account first.

5. Lock down your account

Add an authenticator app, an anti-phishing code and a withdrawal allowlist. It takes three minutes and stops most account takeovers.

Dollar-cost averaging: the easy way

DCA means buying a fixed amount on a fixed schedule, whatever the price. You buy more when it's cheap and less when it's expensive, and you don't have to watch charts. The OKX app has a built-in recurring buy feature.

DCA reduces the risk of buying at the top, but it can't guarantee a profit.

Where to keep your Bitcoin

Bitcoin in 2026

Bitcoin traded around $90,000 early in 2026, pulled back mid-year, and climbed back above $80,000 in late September, briefly topping $87,000 as spot ETF inflows returned. Some institutions have year-end targets of $100K–$150K, but forecasts are often wrong. What matters more is how much you invest, how long you hold and what you'll do in a drawdown.
