In early 2017, China’s three major Bitcoin trading platforms—Bitcoin China, Huobi, and OKCoin—implemented partial deleveraging measures, restricting or suspending margin financing and crypto borrowing services for Bitcoin spot trading. This strategic shift came amid heightened market volatility and regulatory scrutiny, marking a pivotal moment in the evolution of digital asset trading in the region.
Regulatory Pressure Triggers Deleveraging
The move followed a sharp price correction on January 5, when Bitcoin’s domestic price in China surged to nearly ¥9,000 before plummeting over 30% within a single day. The extreme price volatility drew immediate attention from financial regulators. Authorities in Beijing and Shanghai summoned executives from the three platforms, culminating in an on-site inspection led by the People’s Bank of China on January 11.

This regulatory intervention accelerated internal risk controls across exchanges. In response, platforms began limiting leverage exposure—a necessary but painful adjustment given that margin trading fees constituted a significant portion of their revenue.
Impact on Trading Volume and Platform Revenue
The combined effect of price swings and reduced leverage options led to a dramatic drop in trading activity. Daily volumes, which had once exceeded 6 million RMB (approximately $870,000 at the time), fell to under 1 million RMB across the board in the days following the crackdown.
This decline reflects both investor caution and the dampening effect of restricted trading tools. With fewer opportunities for leveraged positions, speculative activity slowed significantly.
For platforms, this was akin to “cutting flesh” from their business model. Revenue streams primarily come from two sources: withdrawal fees and interest on leveraged positions. For example:
- On Bitcoin China, users pay a 0.0001 BTC fee per Bitcoin withdrawal.
- For RMB withdrawals under ¥200, the fee is ¥2; above that threshold, it's 0.38%.
- Huobi charges a daily interest rate of 0.1% on borrowed funds used for margin trading.
Reducing access to these services directly impacts profitability—but it also mitigates systemic risk during turbulent markets.
Varied Approaches to Deleveraging
While all three platforms moved toward reducing leverage, their methods differed:
Bitcoin China: Full Suspension
Effective January 12, Bitcoin China completely halted its borrowing and lending services for spot trading. Users could only repay existing debts, with no new margin positions allowed.
Huobi: Capacity-Based Limitation
Rather than an outright ban, Huobi imposed a cap on total platform leverage capacity. When TechWeb tested the system on January 16, users attempting to borrow reported “insufficient quota.” A customer service representative confirmed that borrowing would resume once current loans were repaid—indicating a dynamic, supply-constrained model rather than a hard stop.
OKCoin: Alignment with Bitcoin China
OKCoin adopted a similar full suspension policy. As of January 16, users could not initiate new financing or borrowing requests—only repayments were permitted.
These differences highlight varied risk tolerance and operational strategies among leading exchanges during periods of regulatory uncertainty.
Understanding Leverage in Crypto Trading
Leverage allows traders to amplify returns using borrowed capital:
- Margin financing (buying on margin): Bullish investors borrow fiat or crypto to increase purchasing power.
- Short selling via coin borrowing: Bearish traders borrow Bitcoin, sell it immediately, then buy back later at a lower price to return the loan and pocket the difference.
Previously, spot trading on Chinese platforms allowed up to 5x leverage, multiplying both gains and losses. However, inexperienced traders often underestimate the risks—especially the threat of liquidation when prices move against them.
Both Huobi and OKCoin set their liquidation threshold at 110%—meaning if collateral value drops below 110% of the loan amount, positions are automatically closed to prevent further losses.
Why Deleveraging Was Necessary
Despite revenue loss, deleveraging was essential for several reasons:
- Risk amplification: High leverage magnifies market swings, increasing the likelihood of mass liquidations.
- Investor protection: Many retail traders lack experience managing leveraged positions.
- Regulatory compliance: Authorities prioritized financial stability over speculative trading growth.
The January 5 crash served as a wake-up call: hundreds of leveraged traders faced automatic liquidations as prices tumbled unexpectedly.

Contract Trading Remains Unaffected
Notably, while spot margin services were curtailed, Bitcoin futures-like contracts continued operating without restriction.
At OKCoin, the international platform maintained normal operations for USD-denominated contract trading. The mobile app offered users a choice between 10x and 20x leverage—significantly higher than the previous 5x cap on spot markets.
Similarly, Bitcoin China confirmed that although spot borrowing was suspended, “professional trading”—referring to its separate derivatives app—remained fully functional with leverage enabled.
On January 4, just before the price peak, Bitcoin China’s professional trading app announced increased margin requirements: initial margin rose from 5% to 7%, though maintenance margin stayed at 2%. This subtle adjustment signaled proactive risk control even before broader restrictions took effect.

Frequently Asked Questions (FAQ)
Q: What does "deleveraging" mean in cryptocurrency trading?
A: Deleveraging refers to reducing or eliminating borrowed funds used to amplify trading positions. It lowers both potential returns and risks, especially during volatile market conditions.
Q: Why did Chinese Bitcoin platforms restrict margin trading in 2017?
A: Due to extreme price swings and regulatory pressure following a 30% intraday drop in early January 2017, platforms limited leverage to protect investors and comply with emerging oversight from financial authorities.
Q: Can you still trade Bitcoin with leverage after spot restrictions?
A: Yes—while spot margin services were suspended, contract or futures-style trading with up to 20x leverage remained available on platforms like OKCoin and Bitcoin China’s professional trading app.
Q: How do liquidation mechanisms work in leveraged crypto trading?
A: If the value of a trader’s collateral falls below a certain threshold (e.g., 110%), the exchange automatically closes the position to prevent further losses. This protects both the platform and other users from counterparty risk.
Q: Did deleveraging affect trading volume?
A: Yes—daily trading volumes dropped sharply from over 6 million RMB to less than 1 million RMB across major platforms, reflecting reduced speculation and lower market participation post-restrictions.
Q: Are there alternatives to restricted domestic platforms?
A: International exchanges continue offering leveraged products with robust infrastructure. Traders seeking advanced tools often explore global platforms that support high-margin contracts with strong security protocols.
The partial deleveraging of Bitcoin spot markets in early 2017 marked a turning point in China’s approach to digital asset regulation. While short-term revenues suffered, long-term market integrity improved. As volatility remains inherent to crypto markets, balancing innovation with risk control continues to shape the future of global trading ecosystems.
