#策略性加码BTC Bitcoin is currently stuck around 91,000-91,500, which is the previous platform top after oscillation and also a key psychological level. After reaching 92,648 on January 13, there was a slight pullback, indicating that this support level is indeed effective.

Looking at the 4-hour chart, the low-level golden cross is still ongoing, with the price climbing along the double moving averages. The RSI indicator remains in the mid-strong zone and has not entered the overbought area. In simple terms, the upward momentum is still building and hasn't overextended.

Below, there are technical supports at the 90,000 integer level and at 89,500, providing double protection. It's quite stable, so there's no need to worry too much.

The trading strategy is also simple:
- $BTC is positioned around 91,000-91,500, with a target of 93,000
- $ETH is entered around 3,080-3,100, with a target of 3,150

$BTC $ETH $XRP's trend correlation still exists and can be referenced for coordinated trading.
