The slight rebound of Bitcoin around 90000 on Friday evening was expected. However, out of caution, the support below being broken indicates that short-term support is weakening. If the rebound is not strong, it will be difficult to break through the resistance above. Directly leading my friends near 91000 without hesitation, we exited smoothly around 88500, and in the afternoon, the follow-up also managed to take advantage of the trend. If Bitcoin does not fall below 88000 again, it is highly likely that the market will enter a phase of consolidation and repair. Attention should be paid to the high level of Bitcoin around 90000, and attention should be paid to 3010-3100 for other altcoins.
