The recent market dynamics of Bitcoin and Ethereum are worth in-depth discussion. Bitcoin has been hovering around the current price level for more than three days, and the significant drop on June 17 may actually indicate a change in market trends. From a Technical Analysis perspective, both the daily chart and weekly chart show fairly obvious short positions signals. The previous rising trend is likely a manifestation of capital exiting the market, and the current rebound near the support level seems more like a brief adjustment in the downward process, rather than a true reversal indicators. If the key support level is broken, the market may accelerate its decline.

Ethereum has formed a key support line in the range of $2500-$2450, but the rebound strength is obviously insufficient. At this time, whether the support level is broken has become a decisive factor for the market direction. If the price continues to consolidate sideways and gradually raises the bottom, then the downward space will be limited. However, whether the support range of $2400-$2450 can effectively support the price needs close attention from investors.

In terms of Bitcoin's short-term trend, the intraday support level of $104 has not been effectively breached yet, and attention needs to be paid to the support situation in the $103-$104 range, while the strong support level is at $1016-$1022. The resistance levels above are mainly concentrated in the $105-$106 range. Currently, the market is showing a fluctuating pattern, and the rebound strength is expected to be limited.

In terms of Ethereum, the support level of $2450-$2500 and the resistance level of $2560-$2580 form a narrow oscillation range, with recent price movements showing a clear pattern: bouncing off the support level and retreating upon reaching the resistance level.

In this market environment, investors should develop reasonable trading strategies to seize the best entry and exit points, avoiding unnecessary losses due to incorrect judgments. The current market is highly volatile, requiring calm analysis and cautious operations.
