On February 4, 2017, Bitcoin was trading at $1,042.90, holding firm above the psychologically important $1,000 threshold despite a turbulent January that saw Chinese regulators subject the world’s largest cryptocurrency exchanges to unprecedented scrutiny. The People’s Bank of China’s month-long inspection campaign had fundamentally altered the landscape of Bitcoin trading in the country that accounted for over 90% of global volume.
TL;DR
- PBoC inspected China’s three largest Bitcoin exchanges — BTCC, Huobi, and OKCoin — throughout January 2017, finding “irregularities” in their operations
- All major Chinese exchanges were forced to eliminate zero-fee margin trading and introduce transaction fees starting January 24
- PBoC summoned nine domestic exchanges to a closed-door meeting, enforcing strict compliance with KYC and AML regulations
- Bitcoin plunged from a near-all-time high of $1,139 to $885 on January 5 following initial PBoC announcements, before recovering to $1,043 by February 4
- The PBoC simultaneously announced plans to establish its own digital currency research institute
The January That Shook Chinese Crypto
Bitcoin entered 2017 with explosive momentum, surging past $1,000 on January 1 for the first time in three years and reaching $1,139.89 on January 4 — just shy of its all-time record of $1,163 on the Bitstamp exchange. The rally was driven in part by Chinese capital flight, as the yuan had shed nearly 7% over the previous year, its worst annual performance since 1994. Bitcoin, which could move money across borders quickly and anonymously, had become an attractive hedge against yuan devaluation.
But the People’s Bank of China moved swiftly. On January 5, the central bank summoned representatives from major Bitcoin exchanges and reminded them that Bitcoin was not recognized as currency under Chinese law. The immediate result was a dramatic 20% crash, with BTC plunging from $1,139 to $885 in a single day as the offshore yuan simultaneously posted its strongest two-day gain on record.
On-Site Inspections and Findings
What followed was a systematic regulatory campaign. The PBoC Shanghai, together with the Shanghai Municipal Finance Office, conducted on-site inspections of BTCC, then the country’s largest Bitcoin exchange. Simultaneously, the PBoC’s Beijing operations office inspected Huobi and OKCoin. The exchanges attempted to reassure users, with BTCC tweeting “All good, just inspections” and OKCoin sending customer service emails stating the inspections were “only to understand the situation” and aimed at maintaining financial stability.
But the findings were significant. The PBoC inspection group — which included representatives from the Department of Business Management, Beijing Municipal Bureau of Finance, and Municipal Bureau of Industry and Commerce — identified what it described as “irregularities” in exchange operations. The statement noted that the inspection would continue with focus on payment settlement, anti-money laundering compliance, foreign currency management, and information security.
Zero-Fee Trading Eliminated
Perhaps the most consequential regulatory action was the forced elimination of zero-fee trading. Chinese exchanges had long operated without transaction fees, a model that critics argued encouraged wash trading and inflated volume figures. The PBoC ordered all exchanges to cease zero-fee margin trading immediately.
BTCC, Huobi, and OKCoin introduced trading fees on or around January 24, with a fourth exchange, Yunbi, following shortly thereafter. BTCC announced it was “reviewing the operating experience of foreign counterparts and the charging of transaction fees, aiming to further curb speculation and prevent violent price fluctuation.” OKCoin took similar measures.
All three major exchanges also suspended margin lending services, eliminating the leveraged trading that had amplified both gains and losses for Chinese speculators.
Nine Exchanges Summoned
As the Lunar New Year approached, the PBoC escalated its oversight by inviting nine Chinese Bitcoin exchanges to a closed-door meeting. Beyond the big three of BTCC, Huobi, and OKCoin, the meeting included CHBTC, BTCTrade, HaoBTC, and Yunbi, among others. The central bank reportedly emphasized two key points: no margin trading would be permitted, and all exchanges must fully comply with know-your-customer and anti-money laundering regulations.
The message was unambiguous. While China was not banning Bitcoin outright — the central bank’s own statement defined it as a “virtual good” — the era of unregulated, high-volume speculative trading on Chinese exchanges was effectively over.
The PBoC’s Own Digital Currency Ambitions
In a twist that illustrated the Chinese government’s nuanced stance on digital currency, the PBoC simultaneously announced plans to establish its own digital currency research institute to study blockchain technology. This signaled that while the central bank was cracking down on private cryptocurrency speculation, it was actively exploring the underlying technology for its own sovereign purposes — a strategy that would eventually culminate in the digital yuan, or e-CNY.
Market Recovery and Global Impact
Despite the regulatory upheaval, Bitcoin demonstrated remarkable resilience. After bottoming near $885 in early January, the price steadily recovered throughout the month, reaching $1,042.90 by February 4. The 24-hour trading volume stood at approximately $155 million, with a total market capitalization of $16.8 billion.
Ethereum, the second-largest cryptocurrency by market cap at $1.01 billion, was trading at $11.43, having gained 8.59% over the previous seven days. The broader cryptocurrency market appeared to be digesting the Chinese regulatory shock and moving forward.
Why This Matters
The PBoC’s January 2017 crackdown on Bitcoin exchanges established a playbook that regulators worldwide would study and adapt. The approach was surgical — targeting specific exchange practices like zero-fee trading and margin lending rather than banning Bitcoin entirely — and effective, bringing Chinese exchange volumes down dramatically while the global Bitcoin market continued to grow.
The events also marked the beginning of a long-term divergence between China’s stance on private cryptocurrencies versus government-controlled digital currencies. The PBoC’s simultaneous announcement of its own digital currency research institute foreshadowed China’s eventual launch of the digital yuan, making it one of the first major economies to develop a central bank digital currency.
For Bitcoin investors, the swift recovery from the January crash to above $1,000 by early February demonstrated the cryptocurrency’s growing resilience to regulatory shocks — a characteristic that would be tested repeatedly in the years ahead as BTC climbed from $1,000 to nearly $20,000 by year’s end.
