From the daily chart perspective, BTC's resistance zone is between 89600-90570. Once the price touches or breaks through this area, there is a potential opportunity to enter long positions during the subsequent pullback—note that this is not a reversal, just a stage of a rebound opportunity.

Looking at the 15-minute cycle, the 93000-94300 range is a clear resistance zone. If the price pushes into this area, it will likely encounter resistance and fall back. When it pulls back to the 15-minute support around 89580-89000, consider going long, but don't be greedy—take quick profits and exit.

The 2-hour cycle provides a clearer picture. The 98170-100470 range is a relatively strong resistance level. After reaching this area, a pullback is expected. The target for the pullback is to return to the 15-minute support zone for support. The lower 2-hour support is at 85770-84140, which is particularly suitable for short positions or waiting for a rebound, allowing for early positioning.
