U.S. stocks fluctuated yesterday, with the S&P 500 even hitting a new all-time high before the close, but the entire day was marked by repeated oscillations. Bitcoin's performance was similarly volatile, testing investors' patience through fluctuations.

**Bitcoin Market Review**

Bitcoin retreated again to the 90,000 level yesterday, then rebounded. The key point now is whether the 90,000 level can be effectively broken. If it breaks down, it will face downward pressure; if it holds, it will remain in a narrow range between 90,000 and 92,500. In the short term, close attention should be paid to whether the one-hour timeframe can gradually recover upward, but a real strength requires volume increase on the daily chart. Support levels are at 90,000-88,800, with resistance above at 92,400-93,700.

**Ethereum's Balancing Act**

Ethereum found support at 3,065 yesterday, completing a rebound but then falling into a narrow range between 3,065 and 3,160. The approach remains consistent—it's still dependent on Bitcoin's direction. As long as 3,066 is not broken, there is room for an upward move, but the prerequisite is volume increase on the daily chart. If this support is broken, weakness will continue. Currently, the market is at a critical point, with the expectation of mainly oscillating in the short term. Support is at 3,066-3,000, resistance at 3,160-3,290.

**Solana's Strong Performance**

Solana is performing relatively better but is also constrained by the 144-line resistance. The key moving forward is the recovery strength on the four-hour timeframe. If it continues to bottom out around the 15-minute chart, it is likely to test the 144 key level again. To truly strengthen, it must stabilize above 144 on the daily chart. Support levels are at 139-134, with resistance at 144-150.
