Could a Non-Crypto Hedge Fund Have Pulled a Bitcoin ‘Big Short'?

Investigating the Feb 5 crypto meltdown: did a Hong Kong fund's short-vol positions in iBit options trigger a derivative-driven market cascade?

Key Takeaways

A large fund—likely Hong Kong-based, using isolated iBit margin—blew up on Feb 5 after short-vol losses dating to Oct 10, triggering a derivatives cascade.
Short-vol strategies (covered calls, straddles) and cheap weekend OTM puts created concentrated gamma exposure; dealer hedging at opens amplified modest weekend moves into sharp daytime selloffs.
iBit's explosive options liquidity let OG Bitcoin holders and crossover funds harvest premiums without selling; moving spot into iBit and OTC trades insulated flows from 13F disclosure.
Market mechanics—margin calls, forced fire-sales, and counterparties booking profits at intraday lows—created recurring bottoms and funded successive price pushes.
Evidence remains circumstantial: tweets, contact checks, and trading breadcrumbs point to a hidden HK fund, but 13F filings and prime-broker records could be the smoking gun.
Actionable signals to watch: early-expiry implied-vol spikes, abnormal iBit options volume, weekend deep OTM put buying, and May 15 13F filings.
