About coinkiki

coinkiki tracks one market: USDT against the Chinese yuan in China's over-the-counter (OTC) peer-to-peer market.

What we publish

• Reference prices. Every 3 minutes we read the public yuan P2P ads on Binance, OKX and HTX and compute buy and sell prices for three ticket sizes: CNY 5,000, CNY 50,000 and CNY 300,000. The method is set out in how coinkiki calculates the USDT/CNY rate.
• The China USDT premium. The gap between those prices and the USD/CNY reference rate, with a daily history and CSV downloads on the data page.
• Explainers for people outside mainland China who deal with the yuan: importers whose suppliers ask for USDT, traders and journalists following Chinese money flows.

What we do not do

• We do not trade, hold or transfer money, and we do not match buyers and sellers.
• We do not recommend or rank exchanges, and our guides carry no sign-up links. Exchange names on this site identify where the data comes from.
• Exchange pages and the comparison table have a "Trade" button that may be a referral link: if you register through it, coinkiki may earn a fee from the exchange. That never changes how prices are calculated or which exchange shows first.
• We do not forecast prices or give investment, legal or tax advice.

Editorial rules

• Price statements are not hand-picked. Statements such as "cheapest exchange over the last seven days" follow one published set of rules applied to the live prices. Editors do not adjust them, and no exchange can pay to change them.
• Legal claims carry a source. Every regulation or case cited gives its document or case number, issuing body, date and a link to the original, checked against the original before publication. If we cannot find a reliable source, we leave the point out.
• Screenshots are real. Screenshots of exchange, government and court pages were taken by our editors from the live pages; captions give the date and the source link, and merchant names and other personal details are blurred.
• Dated articles. Each article shows when it was published and when it was last checked.
• Corrections. If you find an error in the data or an article, write to us at the address below. We will correct it and say so on the page.

A separate Chinese-language site

coinkiki also has a Chinese-language site written for Chinese speakers around the world (it does not serve residents of mainland China). It is not a translation of this one: the two cover different questions for different readers.

Data sources

• Exchange prices: the CNY P2P ads Binance, OKX and HTX show publicly on their websites. A redesign on an exchange's side can pause its prices for a while; each exchange's last update time is shown on the pages.
• Reference rates: daily USD/CNY and USD/CNH rates from ExchangeRate-API.
