Bitcoin outlook for today (May 21): short-term oscillation is slightly bearish; key level is 76,000. In the mid-term, it still remains in a range as it builds a base (as of 12:40, BTC is about $77,500)

 

1. Current price and structure

- Price: $77,400–$77,800; slight rebound during the day, overall weak rebound
- Daily: below EMA15/30, moving averages are aligned bearish; MACD red histogram bars are shortening, rebound momentum is weak
- 4-hour: range-bound at $76,200–$78,200; fierce contention around the midline, limited room for rebound
- Key support: 76,000 (strong), 75,000 (lifeline); key resistance: 78,200, 79,500

2. Today’s outlook (5.21)

1. Short-term (intra-day): range-bound and relatively weak; first watch whether 76,800–77,000 can hold steady. If it holds, a small rebound could reach 78,800–78,200; if it breaks below 76,000, then look down to $74,500–$75,000
2. Mid-term (1–4 weeks): range-bound base-building; as long as 75,000 does not break, it remains slightly bullish. If there is an effective breakdown, the pullback may deepen into the $70,000–$72,000 zone
3. Long-term (second half of 2026): institutional funds dominate, ETF continues net inflows, and the slow bull market tone remains unchanged; there are still challenges within the year with **100,000+** potential

3. Trading approach (ultra-simple)

- Spot: add positions in batches at $75,000–$76,000, stop-loss at $72,000; don’t chase above $78,000+
- Short-term: go slightly long at $76,500–$77,000, stop-loss at $76,000, target $78,800–$78,200; if 78,200 faces pressure, reverse to short
- Position sizing: spot 3–5 lots, short-term 1–2 lots; strictly control leverage
