Today is Bitcoin options expiration, and the bulls and bears are battling at a key price level. From the candlestick pattern, the resistance above is around 90,000. If there is a pullback in this area, consider entering with a light short position, targeting the 87,500 level. Conversely, the support zone between 87,000 and 86,500 is also very important—if the price stabilizes here, it might be worth trying a light long position, aiming for 89,500.

It is important to note that the market will be closed tomorrow, which means liquidity will significantly decrease, and the market may become stagnant. Therefore, tonight's volatility could be the final showdown of this expiration cycle. Short-term high volatility will gradually diminish, and by tomorrow, it may just be a calm consolidation phase.

As for ETH, just follow Bitcoin's rhythm, and there should be no problem.
