Bitcoin has fallen back to the key support level of 88000, and the current opportunity window may be fleeting.

In the short term, the range between 89000 and 90000 is a good rebound target. The fluctuations between these two price levels often test the true intentions of the market. If this area can be successfully broken through, there is still room for further upward movement.

But the real long-term bullish layout point is around 94000. If this position can hold, it means the confirmation of the upward trend, and the imagination space at that time will be much larger.

Ethereum also fluctuates in rhythm with Bitcoin, and the trading volume of related derivatives contracts has shown significant changes in recent days, indicating that there is indeed a lot of attention on these key price levels in the market.
