Bitcoin's recent trend has indeed been a bit tumultuous. From a technical perspective, it is currently oscillating within the 88,500-90,900 range. The short-term rebound momentum is still there, but overall energy is weakening, which means we need to be more cautious.

For recent operations, if BTC can hold above 90,000 and the MACD forms a golden cross again, consider taking a light position to try upward. The target range is 90,500-90,900. But here is the key— the 24-hour high reached 90,945. This level is a real resistance, and a breakout requires volume confirmation; otherwise, it may be pushed back.

Conversely, if it falls below 89,700, be prepared for a downward test, possibly testing 89,000 or even 88,500. If someone is shorting at this point, stop-loss should be set above 90,200. For long positions, set stop-loss below 89,500 to keep losses within a controllable range.

From a medium-term perspective, a range-bound strategy might be more reliable—buy on dips at the lower boundary, short at the upper boundary, and wait for a true breakout signal. If a volume breakout above 90,900 occurs and it stabilizes, then look forward to an upward move toward 92,000-93,000. Conversely, if it breaks below 88,500, consider the possibility of testing 87,000-86,000.

The overall advice is: operate with small positions, strictly implement stop-loss, avoid chasing highs, and follow the key range of 90,000-90,900 to judge the next market direction.
