BTC needs to break the 78K–80K zone with strong volume to confirm entry into a safe bullish zone. Otherwise, as you can see on the chart, this same trendline resistance has already caused two major rejections on the daily timeframe, each leading to a ~34K drop.

If BTC fails to break 78K–80K with solid volume and gets rejected again from this trendline for the third time, there is a possibility of a similar move repeating. That could mean another large drop, potentially targeting the 50K–48K zone.

Patterns tend to repeat, so this level is critical to watch closely.
