Cryptocurrency trading has evolved into a global phenomenon, with digital asset platforms serving as the backbone of this decentralized financial revolution. Among the early pioneers in this space is OKCoin, a name that emerged prominently in the early 2010s as one of the leading cryptocurrency exchanges—particularly in China. While its footprint has shifted over time due to regulatory changes and market dynamics, OKCoin played a pivotal role in shaping how users trade Bitcoin and other digital assets.
This article explores the history, services, trading features, and key developments surrounding OKCoin, offering a clear and updated overview for traders, investors, and crypto enthusiasts.
What Is OKCoin?
OKCoin is a digital asset exchange platform that enables users to trade major cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC) against fiat currencies such as the US Dollar (USD), Euro (EUR), and Japanese Yen (JPY). Initially launched in China, OKCoin quickly rose to prominence due to high trading volumes and strong technical infrastructure.
The platform operates under two main entities:
- OKCoin China: Previously facilitated CNY/BTC spot trading with margin support.
- OKCoin International: Based in Singapore, offering USD/BTC spot pairs, futures contracts, and leveraged trading options.
Although OKCoin's Chinese operations have been scaled back, its international arm continues to serve global clients through advanced trading tools and reliable security protocols.

Founding and Leadership
Founded in 2013 by CEO Star Xu, OKCoin was built on a foundation of technological expertise and strategic vision. Star Xu, a former search algorithm engineer at Yahoo and Alibaba, later served as CTO of DocIn.com—a popular Chinese file-sharing service—where he managed over 120 engineers. His background in scalable systems proved instrumental in building a robust exchange capable of handling massive transaction volumes.
Under Xu’s leadership, OKCoin secured over $10 million in venture funding from notable investors including:
- Ceyuan Ventures
- Ventures Lab
- Tim Draper, the renowned Silicon Valley investor
This backing not only validated the platform’s potential but also accelerated its expansion into international markets.
User Verification and Account Tiers
To ensure compliance with anti-money laundering (AML) and know-your-customer (KYC) standards, OKCoin implements a tiered verification system for users:
- Level 0 (Unverified):
Available immediately after registration. Users cannot deposit or withdraw funds—making trading impossible at this level. Level 1 (Basic Verification):
Requires submission of personal identification. Enables cryptocurrency deposits with daily withdrawal limits:- Up to 200 BTC
- 1,000 LTC
- 5,000 ETH
Level 2 (Full Verification):
Involves additional documentation for higher limits:- Crypto deposits: No restrictions
- Fiat deposits: Up to $100,000 per day
- Withdrawals: Up to $100,000 daily across BTC, LTC, ETH, and USD
These tiers balance accessibility with security, ensuring both new users and institutional traders can operate within appropriate boundaries.
Trading Features and Supported Pairs
OKCoin offers a streamlined yet powerful trading environment focused on core digital assets. The platform supports the following primary currency pairs:
- BTC/USD
- LTC/USD
- ETH/USD
- ETC/USD
Each trade incurs a transaction fee, which scales based on the user’s 30-day trading volume. The maximum fee is capped at 0.2%, with higher-volume traders benefiting from reduced rates.
Margin Trading and Leverage
One of OKCoin’s standout offerings is margin trading, allowing users to borrow funds and trade with leverage. This feature amplifies both potential profits and risks:
- Leverage levels depend on user tier and trading history.
- No requirement to hold full asset balances upfront.
- Enhanced fee structures apply during margin trades.
While powerful, margin trading demands caution—adverse price movements can lead to significant losses or liquidation.
Futures Trading via OKEx
For derivatives trading, OKCoin integrated OKEx, a dedicated sub-platform enabling futures contracts on digital assets. As one of the first exchanges to introduce crypto-based futures, OKCoin provided early access to sophisticated financial instruments that are now standard across top-tier platforms.
Traders benefit from:
- Real-time market data
- Advanced charting tools
- Order book depth analysis
- Risk management features
These tools empower users to make informed decisions in fast-moving markets.
Historical Milestones
OKCoin’s journey reflects broader shifts in the global crypto landscape:
- 2013: Founded by Star Xu; seed round raises $1 million.
- 2014: Secures $10 million in venture capital.
- August 2016: Becomes the world’s largest Bitcoin exchange by volume—processing over 16 million BTC monthly.
- April 2017: Suspends USD deposits due to banking partner issues.
- September 2017: Announces shutdown of CNY-to-BTC trading amid tightening Chinese regulations.
Despite these operational shifts, OKCoin maintained relevance by pivoting toward international markets and expanding derivative products.
Controversy: The Bitcoin.com Dispute
In May 2015, OKCoin became embroiled in a public dispute with Roger Ver, an influential figure in the Bitcoin community, over control of the domain bitcoin.com.
Key points of contention:
- OKCoin claimed it could no longer fulfill payment obligations due to regulatory pressure following Ripple Labs’ $700,000 FinCEN fine linked to Ver’s KYC status.
- Ver countered by releasing encrypted email records showing delayed payments prior to the Ripple incident.
- OKCoin presented a revised contract allegedly signed by both parties, granting them termination rights.
- Forensic analysis revealed that Ver’s digital signature on the new contract matched the timestamp of the original—suggesting possible forgery.
The conflict escalated with bounty offers:
- OKCoin offered $20,000 for proof disproving Ver’s claims.
- Ver countered with a $1 million reward for proof validating the newer contract’s authenticity.
Ultimately, the bounty was paid to a third party who analyzed the cryptographic evidence—damaging OKCoin’s credibility in the process.
