On May 28, Bitcoin and Ethereum gradually rose and fluctuated throughout the afternoon. The plan was to initiate long positions around 108500 and near 2620. The market fluctuated and rose, but the upward space for Bitcoin and Ethereum was limited, so it was timely to exit. The long position strategy captured some profit, and the oil investment was also considered successful. At the same time, one can continue to hold and wait for a little more upward space to enter a short position. Recently, the market has been fluctuating around 108823.9 (describing recent price movements). In the short term, the market remains in a consolidation pattern, with the current situation in a standoff between bulls and bears. The MA7 crossing above the MA30 and stabilizing indicates a certain rebound momentum in the short term, but it lacks volume support, making it difficult to form a strong trend in the near future. There is significant resistance at 109252.6 above, while 108178.1 is an important support level, and it may fluctuate within this range. In the evening, Bitcoin can short between 109000-109500, targeting around 107500; Ethereum can short between 2660-2680, targeting around 2580.
