🚨 US and Israel Attack Iran: Immediate Impact on the Crypto Market (2026-02-28 19:40)

1. Market Data (Most Intuitive)

- BTC: Intraday high ≈ 67,700 → Low ≈ 63,500, maximum drop ≈ 6%, currently around 64,000
- ETH: Maximum drop ≈ 8.5%, currently ≈ 1860
- Mainstream Coins: SOL/DOGE ≈ **-10%, BNB/XRP ≈ -5% to -8%**
- Liquidations: 24h ≈ 150,000 traders liquidated, total amount ≈ $494 million, longs account for 88% (≈$437 million)
- Market Cap: Evaporated approximately $70 billion in 44 minutes (2.24T → 2.17T)

2. Why Did It Drop? (Not Hedging, Risk Assets)

1. Dominated by high-risk attributes: Under geopolitical panic, funds sell off crypto and flow into gold/USD/U.S. Treasuries, turning crypto into a “withdrawal machine”
2. Leverage death spiral: High-leverage contracts (50–125x) concentrate liquidations → Selling pressure → Further decline → More liquidations
3. Hashrate panic: Iran is a key mining country; airstrikes raise concerns about power outages and hashrate damage
4. Institutional redemptions: ETFs/funds redeem cash to cope with volatility, passively dumping prices

3. Impact on Different Products (Most Relevant to You)

1. Spot

- BTC/ETH: Short-term intense volatility, wide fluctuations, support levels moving down
- Arbitrage strategies: Abnormal price spreads, slippage widening, pause new positions, protect existing holdings

2. Contracts (1–150x)

- Volatility surges, liquidation lines move significantly higher, >10x easily liquidates
- Funding rates fluctuate wildly, long-short costs become uncontrollable
- Recommendation: Reduce leverage to ≤3x, shrink positions, enforce strict stop-loss

3. Spot Leverage (1–20x)

- Borrowing interest slightly rises, risk ratio quickly decreases, liquidation risk increases
- Recommendation: Reduce leverage to ≤5x, add margin, reduce borrowing days

4. Options

- Implied Volatility (IV) skyrockets, option prices carry large premiums
- Gamma risk amplifies, small fluctuations can cause severe position losses
- Recommendation: Reduce naked longs/naked shorts, use spread/hedge strategies, shorten expiration dates

4. Future Trend Judgment (Key Variables)

- Short-term (1–3 days): High volatility, leaning bearish, watch Iran’s counterattack strength
- Medium-term (1 week): If war escalates → sustained pressure; if cooling occurs rapidly → rebound
- Long-term: Return to halving expectations, ETF capital flows, Federal Reserve policies

5. Practical Tips for You (Immediate Action)

1. Spot: Do not bottom-fish, do not add to positions, mainly observe
2. Contracts/Leverage: Reduce leverage, cut positions, set stop-loss, prohibit naked longs/naked shorts
3. Arbitrage: Pause opening new positions, hedge existing ones, control risk exposure
4. Monitor: Focus on Iran’s counterattack, crude oil prices, gold trends, BTC liquidation data
