Bitcoin price update: The core pattern I am tracking has now taken shape this week. Last night, I took a short position at the high of the range, and now I am waiting for a larger decline. The short-term profits from earlier have been partially realized, leaving room for subsequent downside. The key point for whether this strategy can continue is $90,300 — once BTC breaks through this level, my expectation will be invalidated. This level is my set stop-loss line. Moving forward, it is necessary to closely observe whether Bitcoin can form resistance around this area as expected, providing a stronger short-selling signal.
