Analysis: BTC rebounded over the weekend, boosted by the US-Iran tensions; $78,500 became a key watershed for options long and short positions.

Bitcoin's weekend rebound was stimulated by news from the US and Iran. The core issue for BTC options this weekend is the weakening of Gamma constraints after settlement, with the $78,500 level remaining a key support/resistance level for Bitcoin. In the short term, if BTC holds above $77,000-$78,000, it's likely to continue its upward trend with some volatility; if it breaks above $80,000 with significant volume, call options may reignite buying interest. Short-term implied volatility remains low, and considering the strong expectation of recent volatility, call spreads/put spreads are more suitable for cost control.
