SafeEntry_v1 — Ultra-Conservative Strategy

Core insight: Over 24 months (May 2024-May 2026), 
BTC went from ~$60K to ~$80K (+34%), BUT with a -51% crash Oct 2025-Mar 2026.
The ONLY way to survive is regime-filtered entries.

Entry: RSI < 25 on 1h (deep oversold) + price > EMA200 + ADX < 20 (mean reversion)

Exit: ROI 4%/2%/1%/0, SL 3%
