How to Buy Bitcoin in Thailand with PromptPay

PromptPay turns a phone number into a bank account, which makes THB transfers instant and free. Licensed Thai exchanges accept it directly; on global exchanges you use PromptPay through a P2P merchant. The second route is fine for small amounts, but the merchant step needs care.

  • Licensed local exchanges take PromptPay directly; global ones use P2P.
  • THB 300–500 is enough for a first test order.
  • Check the merchant completion rate before every trade, not just the first one.

KYC checklist

  • Thai national ID or passport, all corners visible, no glare.
  • Selfie with liveness check; remove glasses and hats.
  • Name must match the bank account linked to PromptPay.
  • Address in the app should match your ID or residence permit.
  • Rejected once? Wait a day; repeated submissions can freeze the account.

P2P safety checklist

  • Pay only the account shown on the order page. Anyone asking you to switch accounts is scamming you.
  • Never cancel an order after paying — cancelling removes platform arbitration protection.
  • Do not move the trade to WhatsApp or Telegram; keep every message and receipt inside the order.
  • A payment screenshot is not proof of arrival. Confirm the balance in your own bank or wallet app.

Frequently asked questions

Can I use PromptPay on a global exchange?

Not as a direct deposit. Global exchanges settle THB through P2P merchants who accept PromptPay. Licensed Thai exchanges support it directly.

Is crypto legal in Thailand?

Digital asset businesses are licensed by the SEC, and trading through licensed platforms is legal. P2P is widely used but carries counterparty risk.

What about tax?

Gains may be subject to withholding and personal income tax depending on how you trade. Keep records and confirm the current treatment with the Revenue Department or an accountant.
