The cryptocurrency market experienced a dramatic downturn on May 19 — an event now widely referred to as the “519 crash” — sending shockwaves through the digital asset world. Bitcoin plummeted over 30% in just 24 hours, while most altcoins dropped more than 50%, wiping out billions in investor value overnight.
This sharp correction wasn't isolated. It came amid shifting macroeconomic conditions and regulatory rumors, including reports that the U.S. Biden administration planned to require tax reporting for crypto transactions exceeding $10,000. With such turbulence, many are asking: Was this the end of the bull run? Is Bitcoin still a viable long-term investment?
To unpack these critical questions, we turn to Yu Jianing, Chairman of the Blockchain Committee at the China Communications Industry Association and Dean of Huobi Education, for expert insights into market dynamics, risk factors, and the future of digital assets.
Understanding the "519" Market Collapse
The sudden crash on May 19 was less about a single trigger and more about a perfect storm of technical and structural vulnerabilities within the crypto ecosystem.

According to Yu Jianing, the primary driver behind the plunge was a cascade of liquidations across decentralized finance (DeFi) platforms, particularly those built on Ethereum. As ETH’s price swung violently, many loans backed by crypto collateral fell below their required thresholds, triggering automatic liquidations.
With network congestion spiking — nearly 20,000 transactions pending at peak times — gas fees soared past 2,000 Gwei, making it nearly impossible for users to repay loans or adjust positions in time. This delay amplified the number of forced sales, creating a feedback loop that accelerated the sell-off.
In just 24 hours, over $314 million in DeFi debt was liquidated, marking an all-time high and highlighting the fragility of leveraged positions during extreme volatility.
Additionally, high leverage in derivatives markets worsened the downturn. Prior to the crash, funding rates for Bitcoin perpetual contracts remained elevated — a sign of overheated bullish sentiment. When prices reversed, highly leveraged traders were swiftly wiped out, adding further downward pressure.
“There’s no such thing as a risk-free high return,” says Yu Jianing. “After prolonged rallies, sharp corrections are not only normal — they’re necessary for healthy market evolution.”
Is the Bull Market Over?
Despite the severity of the drop, Yu Jianing argues that this does not signal the end of the bull cycle. Historical patterns show that strong bull markets often include deep drawdowns.
For example, during Bitcoin’s 2017 rally, the asset suffered multiple corrections of 30–40%, yet continued climbing afterward. The current market structure is similar: driven largely by emotional retail participation and FOMO (fear of missing out), while early institutional investors gradually take profits.
Yu emphasizes that true bull markets don’t die suddenly. They typically go through phases:
- Rapid price increase
- Extended consolidation
- Gradual loss of momentum
- Eventual bear transition
The "519" crash fits better as a leveraged correction rather than a trend reversal. In fact, deleveraging can lead to a healthier, more sustainable market by removing excess speculation and forcing participants to adopt better risk management practices.
What’s Driving This Bull Run?
While global quantitative easing has played a role in inflating risk assets — including cryptocurrencies — Yu Jianing stresses that Bitcoin's rise is not solely tied to monetary policy.
Instead, it reflects broader structural shifts:
- Bitcoin as digital gold: Increasingly recognized as a store of value amid inflation concerns.
- Growing institutional adoption: Companies like Tesla, Square, and MicroStrategy have added Bitcoin to their balance sheets.
- Mainstream financial integration: PayPal, Morgan Stanley, and Goldman Sachs are expanding crypto services.
- ETF approvals and regulated products: Growing investor access through compliant vehicles.
These developments point to a deeper global consensus forming around Bitcoin’s long-term utility — not just as a speculative asset but as a foundational piece of the future digital economy.
“Bitcoin is becoming the dollar of the digital world,” Yu notes. “As blockchain use cases expand, so will demand for Bitcoin as reserve collateral.”
Regulatory Impact: Will Tax Rules Kill Crypto Momentum?
News that the U.S. may require reporting of crypto transactions over $10,000 sparked panic, but Yu Jianing sees this differently.
In reality, the IRS has treated crypto as taxable property since 2014. The proposed rule is less about new taxation and more about enhanced compliance and transparency — part of a broader trend toward regulation.
While tighter oversight may create short-term uncertainty, it also signals maturation. Regulation reduces fraud, increases trust, and paves the way for wider institutional participation.
Yu believes that despite regulatory challenges, the trajectory remains clear: digital assets are moving toward mainstream acceptance, with compliance as a prerequisite for long-term growth.
The Danger of Meme Coins and Speculative Mania
One troubling trend before the crash was the surge in retail investors chasing so-called “animal coins” — meme-driven tokens with little intrinsic value.
These speculative assets attracted FOMO-fueled money, distorting market sentiment and inflating bubbles. When reality hit on May 19, many retail traders faced devastating losses.
Yu warns that non-rational speculation is unsustainable. True value lies in blockchain innovation that solves real-world problems — from cross-border payments to supply chain transparency.

Still, he doesn’t believe this crash will halt capital inflows. Why? Because the real engine behind this bull market is institutional capital, not retail speculation.
Firms like BlackRock, Fidelity, and ARK Invest are allocating to Bitcoin based on rigorous analysis — not hype. Their involvement ensures continued momentum even after speculative frenzies fade.

Frequently Asked Questions (FAQ)
Q: Was the "519" crash caused by one single event?
A: No single factor caused the crash. It resulted from a combination of DeFi liquidations, high leverage in derivatives markets, network congestion on Ethereum, and negative regulatory sentiment.
Q: Does this mean the Bitcoin bull market is over?
A: Not necessarily. Historically, strong bull markets include sharp corrections. The "519" drop appears to be a healthy deleveraging phase rather than a bear market signal.
Q: Are meme coins safe investments?
A: Meme coins carry extremely high risk due to lack of fundamentals. They’re often driven by social media hype rather than technology or utility.
Q: How does regulation affect crypto prices?
A: Short-term fear may cause dips, but long-term regulation brings legitimacy, reduces fraud, and encourages institutional investment.
Q: Should I sell my crypto after such a big drop?
A: Investment decisions should align with your risk tolerance and time horizon. Volatility is inherent in crypto; holding through downturns may yield long-term gains if you believe in the underlying value.
Q: Can blockchain technology survive market crashes?
A: Absolutely. Market cycles don’t erase technological progress. In fact, downturns often weed out weak projects, allowing stronger innovations to thrive.
Final Outlook: Volatility Is Part of the Journey
The "519" crash was painful for many, but it served as a reality check for an overheated market. While retail speculation surged, the foundation of this bull run remains intact: growing institutional interest, expanding use cases, and increasing global recognition of blockchain’s transformative potential.
Yes, further corrections are likely. But volatility is not failure — it’s part of the process of building a resilient digital financial system.
As Yu Jianing concludes:
“Every major downturn creates opportunity. Those who understand the technology and stay disciplined will emerge stronger.”
