Today's Mainstream Cryptocurrency Trend Analysis:

$BTC

The actions of the United States against Iran have triggered a market sell-off. Currently, the daily support is temporarily effective, and support around the 100,000 level is crucial. The resistance level to watch is the 4-hour mid-range of 104,000-105,000. If it cannot break through or shows a false breakout, consider shorting.

$ETH

A bullish divergence has appeared at the hourly level, indicating a short-term need for a rebound, but the daily chart is still below the zero axis, with the technical outlook favoring bears. Be cautious of a rebound after a sharp decline, and watch the support levels of 2180-2150.
