Purchasing cryptocurrency with a credit card in Taiwan has become a popular method for both beginners and experienced investors seeking fast and convenient access to digital assets. While local financial regulations impose certain restrictions, international crypto exchanges like OKX and Binance still allow users to buy crypto using credit cards through third-party payment processors. This guide walks you through everything you need to know—from supported banks and step-by-step tutorials to rewards, risks, and best practices.
Can You Buy Crypto with a Credit Card in Taiwan?
The Financial Supervisory Commission (FSC) of Taiwan views cryptocurrencies as high-risk instruments prone to money laundering and illegal activities. As such, it only recognizes a limited number of local platforms as compliant "Crypto Asset Service Providers."
In 2022, the FSC issued guidelines stating that credit cards—primarily designed for consumption—should not be used for investment or speculative transactions. Consequently, banks are prohibited from processing credit card payments for domestic crypto platforms.

However, this restriction applies mainly to local services. International exchanges such as OKX and Binance operate in a regulatory gray area, allowing Taiwanese users to purchase cryptocurrencies via third-party payment gateways. While not explicitly illegal, users should remain cautious and stay updated on evolving regulations.
Credit Card Bank Compatibility: Real-World Testing Results
Based on real transaction tests conducted in early 2025, here is an overview of which Taiwanese credit cards work on Binance and OKX:
- ✅ Success: Card successfully processed a crypto purchase
- ❌ Failure: Transaction declined
- ▢ Not Tested Yet
| Bank | Binance | OKX |
|---|---|---|
| Fubon Bank | ❌ | ❌ |
| DBS Bank | ▢ | ✅ |
| Cathay United Bank | ❌ | ✅ |
| Taishin Bank | ✅ | ✅ |
| Bank SinoPac | ✅ | ✅ |
| E.Sun Commercial Bank | ✅ | ▢ |
| Others (e.g., CTBC, Post Office, Federal) | ▢ | ▢ |
Note: Test results as of March 2025. Performance may vary based on individual account settings and bank policies.
From these results, Taishin, SinoPac, and Cathay United show strong compatibility with at least one major exchange. Cards from Fubon and Federal—including JCB variants—consistently fail, suggesting stricter internal filters against crypto-related transactions.

Troubleshooting Failed Credit Card Purchases
Encountering errors when buying crypto? Common causes include:
1. Insufficient Credit Limit or Transaction Block
Some banks automatically block suspicious international transactions. Contact customer service to:
- Enable overseas usage
- Increase transaction limits
- Whitelist crypto-related payments
2. Card Not Supported by Exchange
Not all cards work—even if issued by Visa/Mastercard. Try switching cards or use Apple Pay as an intermediary layer.
3. Third-Party Payment Gateway Issues
If Simplex or Banxa is down, switch providers within the exchange interface or retry later.
