Recent technical analysis of Bitcoin shows positive signals. From the BOLL indicator perspective, Bitcoin's price is currently operating near the upper band, indicating that the market is in a relatively strong position. It is worth noting that the medium term of the BOLL maintains an upward trend, providing strong support for Bitcoin. Meanwhile, the expansion of the BOLL opening suggests an overall upward trend.

Despite encountering some resistance near the upper band, the rapid buying intervention highlights the market's resilience. This performance aligns with the strong consolidation characteristics seen in a bull market, suggesting a greater likelihood of continued rise in the short term. However, investors must remain cautious, and it is crucial to set appropriate stop loss positions.

For potential trading opportunities, Bitcoin can consider establishing long positions in the range of 120500-120000, with a target price set around 121000. As for Ethereum, there are also long opportunities in the range of 4700-4630, with a target price looking towards 4780.

It is worth mentioning that Ethereum has recently broken through the $4600 mark, and this breakthrough may bring new momentum to the cryptocurrency market. However, investors should always pay attention to market changes and manage risks sensibly. While there are many opportunities, it is also important to stay clear-headed and avoid blindly chasing highs.
