## Bitcoin Technicals Face Critical Test: Can Support Levels Hold?

Currently, Bitcoin is fluctuating around $91.17K, with a gain of +1.12%. Market focus is on the key resistance level at 90333, which is both a previous high and a stubborn resistance that has been tested multiple times without success. From a technical perspective, Bitcoin has experienced a clear downtrend after a period of stagnation, breaking out of the flag pattern. The simultaneous decline in volume and price indicates this is not a false dip but a genuine technical breakdown.

## Support Level System Faces Multiple Tests

At present, Bitcoin is testing the strength of multiple support levels. The 87388 level can only serve as a buffer and does not provide substantial support. The real critical line is at 86750; once broken, the downside space will further open. It is worth noting that on the 4-hour chart, the EMA20 and 50-day moving averages are still in effect, and the decline has not yet expanded below them, providing a technical basis for a rebound.

## Key Trading Range and Strategies

**Hourly Level**: If Bitcoin breaks through 88989 with volume, consider chasing long positions on the right side, targeting the 89343-90311 range; if it drops below 88070 with volume and cannot recover, then consider chasing short positions. Be sure to set stop-loss orders.

**4-Hour Level**: 87928 is an important support point. A break below could lead to a move toward 87377-86582; if it cannot reclaim above 87928, continued pullback pressure will follow.

## Rebound Signs and Observation Focus

A positive signal is that in this rebound, the 4-hour chart has formed a higher high and touched the EMA200, indicating that upward momentum has not been completely lost. The key is whether the market can consolidate without breaking below the low of 86750. Going forward, closely monitor volume changes, as the ability of volume to match price movements will determine the future direction.

Currently, Bitcoin is at a technical crossroads. Breaking through 90333 would truly signal the start of an upward trend, while losing 86750 warrants caution for further downside risk.
