Looking at Bitcoin's 4-hour setup, the 89.4K level is shaping up as critical resistance to watch. On the shorter 15-minute timeframe, things get more interesting—holding above 87.1K through the weekend becomes essential. A push into the 88.88K zone would be the ideal scenario here. But here's the thing: if price fails to move up into the next supply zone, the downside risk increases materially. That's when we could see a notable drop unfolding.
