How to Buy Bitcoin in Thailand 2025 — Step-by-Step Guide

By

Buying Bitcoin in Thailand is straightforward — you can go from zero to owning BTC in under 30 minutes using PromptPay. Here’s the complete step-by-step guide.

What You Need Before Starting

  • Thai National ID or passport
  • Thai bank account with PromptPay enabled
  • Smartphone with your banking app
  • Email address
  • Minimum 20 THB to invest

Step 1: Choose an Exchange

For Thai beginners, we recommend Bitkub — Thailand’s largest SEC-licensed exchange with direct PromptPay deposits and Thai Baht trading pairs. Gulf Binance is also excellent and SEC-licensed.

Step 2: Create Your Account

  1. Download the Bitkub app (iOS or Android) or visit bitkub.com
  2. Tap “Register” and enter your email and password
  3. Verify your email address
  4. Enter your personal details (name, phone number, date of birth)

Step 3: Complete KYC Verification

  1. Go to Account → Verification
  2. Upload a photo of your Thai National ID (front and back)
  3. Take a selfie holding your ID for liveness verification
  4. Wait for approval — usually instant to 24 hours

KYC is mandatory on all SEC-licensed Thai exchanges. Your data is protected under Thai law.

Step 4: Deposit Thai Baht via PromptPay

  1. Go to Wallet → Deposit → Thai Baht
  2. Select PromptPay
  3. Enter the amount you want to deposit
  4. Open your banking app and scan the QR code shown
  5. Confirm the transfer in your banking app
  6. THB appears in your Bitkub wallet within seconds

Step 5: Buy Bitcoin

  1. Go to Trade → BTC/THB (Bitcoin / Thai Baht pair)
  2. Select “Buy” and enter either the THB amount you want to spend or the BTC amount you want to buy
  3. Review the transaction — note the current price and fee (0.25%)
  4. Tap “Buy Bitcoin”
  5. Bitcoin appears in your wallet immediately

You can buy as little as 20 THB worth of Bitcoin — there is no minimum order size that would prevent small purchases.

Step 6: Secure Your Bitcoin (Optional but Recommended)

For small amounts, keeping Bitcoin on Bitkub is fine. For larger holdings, consider moving to a hardware wallet (Ledger, Trezor) for maximum security. Bitkub stores most funds in cold storage, but “not your keys, not your coins” is a fundamental crypto security principle.
