$BTC 4H TF analytics. Bitcoin is testing a key ascending trendline that has held since July's low near $58K, widely considered the bottom of the yearly bear cycle. The broader trend may be turning bullish, but BTC is arguably still in the pre-bull phase. The key hurdle remains $87K, where the January sell-off accelerated. After failing to break through that resistance, BTC has spent over a month correcting. For now, buyers need to reclaim $80K — the descending trendline and nearest resistance — before another attempt at $87K becomes realistic. The July trendline is now facing its 4th retest. A breakdown isn't confirmed, but prolonged consolidation here would favor sellers. Downside targets: $70K and $67K (horizontal support).
