The price of Bitcoin encountered significant resistance at the 120,000 level, showing a high and then a drop yesterday. A medium bearish candlestick with an upper shadow formed on the daily chart, and after an increase in trading volume, a top adjustment occurred with considerable volatility. If it cannot break through 118,500 in the short term, the downtrend may continue, testing lower support levels.

Although Ethereum is still oscillating at a high level, the momentum is weakening, possibly forming a double top pattern, which indicates a potential trend reversal risk. In the short term, the price may fluctuate within a range, but it is more likely to test the support levels downward, particularly around 3730 and 3640. The high resistance at 3820 is difficult to break through in the short term. After the MACD indicator's death cross, the histogram has turned from red to green, indicating that bearish strength is increasing, but it has not yet fully dominated the market.

For Bitcoin, you might consider shorting when there is a rebound in the 118300-118600 range, with a stop-loss set at 119200 and a target price in the 117200-116800 range. If it breaks the support, it may further drop to the 116300-115900 area. If the support holds, you might consider going long.

The trading strategy for Ethereum is similar. You can short when there is a rebound in the 3795-3805 range, with a stop loss at 3835 and a target price in the 3730-3740 range. If it breaks support, it may further dip to the 3700-3710 area. If support holds, consider going long.
