# About coinpay

Canonical page: https://coinpay.hk/en

coinpay is a multilingual USDT P2P rate and premium reference. Compare public USDT buy/sell prices on Binance and OKX with a fiat FX reference. Check the quote time and costs before acting.

It covers 29 fiat markets: public Binance P2P and OKX P2P quotes are compared with a USD FX reference, and KRW uses the Bithumb spot price. Every 30-minute sample since August 2026 is archived permanently. Browse daily history for each market or download CSV and JSON files under CC BY 4.0.

## Independence
coinpay is an independent reference, not an exchange service, and is not affiliated with Binance, OKX or Bithumb. It only reads public ads and public prices; it does not place trades.

## Languages
The website is available in six languages: Chinese (Simplified), English, Korean, Vietnamese, Arabic and Spanish. These Markdown guides are in English.

## Data license
The open data is free to use, share and adapt under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/); please credit coinpay.hk with a link. See [Open data](https://coinpay.hk/data.md).

## Not financial advice
Public quotes are indicative. Check order limits, payment compatibility, KYC and execution costs. A premium is not a guaranteed profit. Quoted premiums and cross-platform spreads are not net trading profits, and nothing on coinpay is financial advice.
