Bitcoin Crashes 40% — Is Crypto Winter Back?
Bitcoin plunged 40% from its peak, falling to the $70,000 level. Roughly $2 trillion in total cryptocurrency market capitalization was wiped out, with the collapse of a Hong Kong hedge fund identified as the key trigger for the crash.

In the first week of February 2026, Bitcoin plummeted 40% from its peak, dropping to the $70,000 level. According to Forbes, approximately $2 trillion in total cryptocurrency market capitalization was erased, and Fortune reported it as the worst single-day decline since the FTX collapse. Ethereum, Solana, and other major altcoins fell sharply in tandem, rapidly fueling fears of a repeat crypto winter.
The Crash Trigger: A Hong Kong Hedge Fund Collapse
According to an investigative report by Fortune, the primary trigger for this crash was the forced liquidation of leveraged positions held by a major Hong Kong-based cryptocurrency hedge fund. The fund had built a substantial long position in Bitcoin futures, but was unable to meet margin calls amid a broad flight from risk assets driven by Trump tariff threats. This set off roughly $8 billion in cascading sell orders, with liquidation engines at global exchanges amplifying the price decline.
$2 Trillion Wiped Out Amid Spreading Market Fear
According to Forbes, approximately $2 trillion was erased from the total cryptocurrency market — including Bitcoin — in just three days. This is comparable to the scale of losses seen during the 2022 crypto winter. The Crypto Fear & Greed Index dropped to 12, signaling extreme fear. Large outflows were also recorded from BITO, the Bitcoin spot ETF, and the situation was compounded by an incident at South Korea's Bithumb exchange, where a system error resulted in approximately $40 billion being incorrectly credited to users.
Altcoin Selloff and Leverage Risk
While Bitcoin fell 40%, Ethereum dropped more than 50% and Solana tumbled nearly 60%, with altcoins suffering steeper losses overall. This reflects thinner liquidity and a higher proportion of leveraged trading in the altcoin market. Investors in leveraged products like TQQQ can draw an important lesson from this event. Triple-leveraged products can see losses expand exponentially in a downturn, so limiting exposure to no more than 5% of the total portfolio is a fundamental principle of risk management.
Comparative Analysis with the FTX Collapse
This crash shares several similarities with the 2022 FTX collapse — excessive leverage, opaque fund management, and cascading liquidations were all repeated. However, there are differences as well. Bitcoin spot ETFs are now listed and institutional investor participation has grown, and the regulatory infrastructure has also been strengthened. CNBC characterized this sharp decline as a technical correction driven by leveraged liquidations rather than a structural crisis, noting that fundamental damage appears limited.
Managing Cryptocurrency Allocation Within a Portfolio
This event reaffirmed the importance of asset allocation for investors who hold cryptocurrency in their portfolios. Using the asset allocation calculator, the recommended allocation to crypto is just 1–5% of a total portfolio. At that level, even a 40% crash can be contained to within a 2% loss for the overall portfolio. Investors should use a rebalancing calculator to systematically buy after a sharp decline when the allocation has become underweight, and to take profits when the allocation becomes overweight after a surge — maintaining disciplined execution.
Conclusion
Bitcoin's 40% crash has once again exposed structural vulnerabilities in the cryptocurrency market, but the maturation of spot ETF infrastructure and growing institutional participation may lead to a different outcome than past crypto winters. Investors should remember that disciplined allocation management through a rebalancing calculator — rather than panic selling driven by fear — is what determines long-term performance.
