2 of the exchanges we recommend in Thailand take PromptPay for funding bitcoin purchases. It is one of several rails in use here; the full picture is in the Thailand guide.
What is PromptPay?
PromptPay is Thailand's national bank transfer service, launched in 2016 and run under the Bank of Thailand's payment system framework. It lets you move baht between Thai bank accounts using a mobile phone number, a citizen ID number or a plain account number, from any Thai bank's app, internet banking, ATM or branch. It is the everyday way Thai residents pay each other and fund accounts with Thai platforms, and one mobile number or citizen ID can be linked to only one account.
- Speed
- Transfers are credited immediately: Bank of Ayudhya states that the payee receives the money as soon as the payer sends it.
- Cost
- The Bank of Thailand's ceiling is free up to 5,000 baht, then under 2 baht to 30,000, under 5 baht to 100,000 and under 10 baht above that, but most banks have waived the charge on app and internet transfers since 2018.
- Limits
- PromptPay sets no cap of its own: each bank sets the per transaction and daily transfer limits in its own app, and you can usually raise them there before a large deposit.

Watch: how to choose an exchange
We have not filmed a walkthrough for Thailand yet, so this is our general one, from our YouTube channel @dontgetrekt. It also sits on the home page, next to the country search it starts from.
Do you need a VPN?
A VPN hides which sites you visit from the network you are on and from your internet provider, which is worth having when you move money over a connection you do not control. It does not get you past an exchange's identity checks: every platform we list verifies who you are no matter where you connect from.
If you want one, the strongest records on our list belong to NordVPN (6 independent no-logs audits, the most of any service we review), Windscribe (its no-logs claim tested in the real world 3 times) and Proton VPN (the most audited service with a free tier).

Frequently asked questions
Which exchanges accept PromptPay in Thailand?
Of the 4 exchanges we recommend in Thailand, Binance and Coinmama accept PromptPay for funding purchases.
Is buying bitcoin with PromptPay legal in Thailand?
Bitcoin is legal in Thailand under the Emergency Decree on Digital Asset Businesses of 2018, with the Thai SEC licensing exchanges, brokers, and dealers. The government sweetened the licensed route with a personal income tax exemption on crypto capital gains realized through SEC-licensed operators, covering the start of 2025 through the end of 2029, while regulators have moved to block unlicensed foreign platforms. Using digital assets as a means of payment has been prohibited since 2022.
How long does a PromptPay deposit take?
Transfers are credited immediately: Bank of Ayudhya states that the payee receives the money as soon as the payer sends it. That is the rail itself; an exchange may hold a first deposit for longer while it verifies your account.
