Bitcoin has been under some pressure at high levels these past couple of days. The lowest point was around $90,635 the day before yesterday, then it pulled back to $91,300 during midday. Over the past 24 hours, there hasn't been much change, just a technical adjustment at the high end.

From a trading perspective, short-term selling pressure seems to be easing. The buy orders are quite solid in the $90,600 to $90,800 range, and if there's a rebound, it might face resistance around $91,800 to $92,000. What's really interesting is the underlying support—institutional ETF inflows have been continuous, and Bernstein's optimistic long-term outlook of $150,000 adds a solid foundation of support.

Now, the $90,000 mark has become a battleground for bulls and bears. Breaking through or holding this level is very critical.
