The upward trend line of Bitcoin was broken during the day today, rebounding to around 80,000 in the afternoon but unable to rise further, just near the trend line, facing resistance. Tonight, Bitcoin is likely to pull back first. A pullback near 80,000 with a stop loss set at 81,200, and support levels at 78,000 and 76,500. This position is suitable for a short position.

Bitcoin's rebound is quite decent; at this position, a long position should be taken for a rebound. Long positions can wait for a breakout of the downward trend line and for Bitcoin to stand above 80,000 before entering, or enter on a pullback near 78,000 for a bottom-fishing opportunity, with a stop loss of just one point.

It's another time for a market change. Due to network issues, I just couldn't send this out, there was a delay, but it can serve as a reference.
