Bitcoin has been somewhat "slow to heat up" recently, oscillating within the small range above 90,000, with little fluctuation in gains and losses. Although there was a surge yesterday, it quickly lost momentum, indicating that every rebound is met with some profit-taking, and the upward pressure remains quite heavy.

From a technical perspective, the two lines of the MACD are gradually trending higher, which is a positive signal—indicating that selling pressure is waning and buying strength is slowly accumulating. However, the situation has not been completely broken yet, so it’s too early to say that the trend has truly turned bullish.

Looking at the data, 89,000 is the support level for this wave of consolidation. As long as this level holds, there is still room for further movement in the short term. Meanwhile, 93,600 has become a key resistance level that needs to be broken. Once it is surpassed, the subsequent trend will become clearer.

**Bitcoin Trading Strategy for January 12:**
Strategy 1: Go long in the 89,400-90,200 range, with a stop loss below 88,600, targeting 91,400-92,200.
Strategy 2: Go short in the 92,700-92,100 range, with a stop loss above 93,500, targeting 91,050-90,100.

**Ethereum Trading Strategy for January 12:**
Strategy 1: Go long in the 3,045-3,080 range, with a stop loss below 3,020, targeting 3,145-3,180.
Strategy 2: Go short in the 3,205-3,175 range, with a stop loss above 3,235, targeting 3,115-3,088.

The short-term key is to see whether the support levels can hold and whether resistance levels can be effectively broken.
