OKCoin is a digital asset trading platform providing spot trading services between the US dollar, Euro, and Japanese yen as fiat currencies, and Bitcoin, Litecoin, Ethereum and other digital assets to customers around the globe. OKCoin Exchange China operated a CNY/BTC spot pair with margin trading from its Beijing entity, while OKCoin International operates a USD/BTC spot pair with margin trading and BTC/USD futures from its Singapore entity.
OKCoin was founded by CEO Star Xu in 2013 and has raised US$ 10 million in investments from Ceyuan Ventures, Mantra Capital, Ventures Lab and other notable private investors including Silicon Valley investor Tim Draper.
In February of 2017, OKCoin and Huobi, the two largest Bitcoin exchanges in China, were flagged by the People’s Bank of China for operating a trading platform without appropriate Know Your Customer (KYC) and Anti-Money Laundering (AML) systems.
In May of 2017 OKCoin, have been accused of using idle clients funds to make investments in “wealth management products“ which are often high-yielding and risky.
In September 2017, OKCoin announced to stop Yuan-to-Bitcoin trading by October's end. 
On May 23, 2015, OKCoin made public a contractual dispute the company was having with Roger Ver over the management rights to the domain name "bitcoin.com."[non-primary source needed][unreliable source?] OKCoin management claimed that they could no longer pay Ver the money which was contractually owed to him due to a recent case in which Ripple Labs was fined $700,000 by FinCEN for failure to collect proper KYC paperwork from Ver. In response, Ver published several months of email history between himself and OKCoin demonstrating that OKCoin had not been making payments for several months prior to the news about Ripple's fine. In the emails, OKCoin CEO Star Xu claims to have discovered a more recent version of the contract signed by both parties, which included a clause that gave OKCoin the right to terminate the contract upon six months notice. Until this point, all communications between the two parties had been cryptographically signed using GPG, but Ver was able to prove that the newer version of the contract was signed with the same timestamped signature he appended to the previous version of the contract, indicating that his signature was merely copied over to the new document. OKCoin proceeded to make a public offer of a $20,000 reward for anyone who was able to prove that Ver's statements were false; Ver responded in kind by offering a $1,000,000 reward to anyone who could prove that the signature on the more recent contract was actually valid and not a forgery. The OKCoin reward was paid at the end of May, 2015 following the report of analysis of the contracts posted publicly by OKCoin.
