January's new weekly market trend continues to maintain a rebound rhythm, with major mainstream cryptocurrencies successively surging higher. Let's review the key technical levels one by one.

**Bitcoin** is currently facing resistance around 93,500. From the weekly chart, 88,600 is a key support level from last week, and the rebound to this point has shown significant height. In the short-term, the 93,500-94,500 range constitutes an important resistance zone, which is currently a key short-selling opportunity. Since the morning, the price has rebounded from the bottom and accumulated about a thousand points in profit. If the rally continues higher, caution is still needed around 94,600. If there is a rapid decline intraday, support levels are sequentially at 91,500-90,500, with further support near 89,300-88,700 if broken. It is advisable to wait for these support zones before entering long positions.

**Ethereum**'s resistance level remains around 3,260, and the last segment still needs to be filled. During the second surge, continue to monitor this resistance. Short-term short opportunities are in the 3,260-3,300 range, while medium-term short opportunities are in the 3,400-3,450 range. The daily support levels for a pullback are at 3,117-3,076, with a defensive support at 3,033. Bulls should patiently wait until near the second and third support levels before considering entry.

**Solana**'s current short-term support for a pullback is at 133. As long as it does not break below this level, the rebound trend remains intact, and existing short positions can be reduced here. The upward rebound resistance zone remains at 140-145. If the price surges into this range, further attention should be paid to short opportunities. Conversely, if this wave breaks below 133, it indicates the small-scale rebound has ended, and the next support test is at 130-128. Bulls should wait until at least this support zone before considering an entry.

**Binance Coin** has surged into the 900-930 resistance zone. For those with short positions, the key defensive level is at 930. If there is a pullback intraday, support levels are sequentially at 880, 870, and 860. Bulls also need to wait until near the second and third support levels before considering building positions.
