$BTC $ETH Today (March 18, 2026) BTC and ETH overall show weakness, with the market in pullback mode. Community discussions mostly suggest weak rebounds, gradual declines, or sideways consolidation are more likely than rapid rallies. Sharp drops (another 10-20% downside) have higher probability than quick surges.

**Current approximate prices** (based on multi-source data aggregation):
- BTC ≈ 70,800–71,000 USD
- ETH ≈ 2,190–2,200 USD

**Precise long/short entry levels** (combining common Fibonacci retracements + recent support/resistance + community/TradingView mainstream views):

**BTC**:
- Long entry: Dip to **69,780–69,900** (Fibonacci 0.382–0.5 retracement + short-term support, bullish structure intact if not broken), stop loss below 69,300.
- Short entry: Rally rejection at **71,200–71,500** (intraday resistance + prior highs failure zone), stop loss above 71,800, targets 68,300–66,500.
- Calculation basis: Short-term bullish floor ≈ prior low + (recent high-low) × 0.382 ≈ 69,780; bearish resistance ≈ intraday high - ATR(14)×1.5 ≈ 71,200–71,500.

**ETH**:
- Long entry: Dip to **2,155–2,190** (intraday low support + recent consolidation zone, bullish bias if not broken), stop loss below 2,120.
- Short entry: Rally rejection at **2,250–2,300** (short-term resistance + prior highs), stop loss above 2,350, targets 2,100–1,990.
- Calculation basis: Short-term support ≈ prior low + (recent rally magnitude) × 0.236–0.382 ≈ 2,155–2,190; resistance ≈ current price + ATR(14)×1.2 ≈ 2,250–2,300.

**Community discussion probability summary**:
- Rally (rapid breakout to new highs) probability: ≈ 25–35% (requires holding 71k/2.3k + volume, most consider short-term challenging).
- Sharp drop/continued decline probability: ≈ 60–70% (mixed sentiment leans bearish, common expectations target 68k–66k / 2k–1.9k or even lower; late bear market consolidation before final dip view more prevalent).
