Briefing
Bitcoin experienced a sharp price crash, falling from approximately $91,300 to nearly $87,000 within hours, wiping over $144 billion from the total crypto market capitalization. This significant decline was primarily triggered by a major exploit on the DeFi platform Yearn Finance, where hackers drained its yETH pool, intensifying existing market pressures from heavy deleveraging and thin weekend liquidity.

Context
Before this recent downturn, many investors were keenly watching Bitcoin’s ability to maintain key support levels amidst ongoing concerns about inflation and consistent outflows from Bitcoin exchange-traded funds. The market was already in a state of cautious anticipation, wondering if underlying structural weaknesses would lead to a deeper correction or if the asset could find a solid footing for a rebound.

Analysis
The market’s recent plunge was a classic example of a “perfect storm” of factors. The immediate catalyst was a security exploit on Yearn Finance, a decentralized finance platform, where attackers manipulated a yETH liquidity pool. This incident eroded confidence in the broader DeFi ecosystem, prompting traders to rush for exits and creating a wave of panic selling. This vulnerability hit a market already under pressure from heavy deleveraging, which means many traders had borrowed heavily to amplify their positions, making the market highly sensitive to any negative news.
Think of it like a stack of dominoes → once one falls (the DeFi exploit), it quickly knocks down others (leveraged positions getting liquidated), accelerating the price drop, especially during periods of thin weekend liquidity where fewer buyers are present to absorb the selling pressure.

Parameters
- Bitcoin Price Drop → Bitcoin fell from approximately $91,300 to nearly $87,000, losing over $5,000 within hours.
- Market Cap Loss → Over $144 billion was removed from the total crypto market capitalization.
- Yearn Finance Exploit → Hackers drained the yETH pool and routed 1,000 ETH through Tornado Cash.
- Key Support Level → Bitcoin is currently holding near the $87,000 level.
- November Decline → Bitcoin declined more than 16% in November.

Outlook
Looking ahead, the immediate focus is on whether Bitcoin can firmly hold the $87,000 support level. A sustained break below this point could see prices test lower thresholds around $80,400 or even $75,000 if market fear escalates. Conversely, the market is closely watching for signals from the Federal Reserve, as an anticipated December rate cut could inject fresh liquidity, potentially catalyzing a rebound towards the $95,000 → $100,000 range in the coming weeks.
