Analysis of recent trends in BTC:

Daily rebounds are all on an hourly basis, currently focusing on indicators above the daily chart.

1-day line: It has been oscillating below the lower boll since 12.19, with support at 91050/90850 and resistance at 98500.

2-day line: The two lines are opening downward, and the downward momentum has been continuously strengthening in recent days. The bottom of this level: near 92150. Resistance: 97400.

3-day line: The two lines first opened downwards, and the downward momentum has a certain strengthening trend. It has now reached around 93300 on the boll center line. The probe near 92800 in the early morning belongs to a false breakthrough, and the rebound in the morning is the result of touching the boll center line. The upper rail of this level of boll is 10.8-11w, and the lower rail is 7.6w. The center rail has not been broken for the time being, and there is support between the center and lower rail at 8.6w, so the lower rail is not a reference.

5-day line: temporarily three consecutive declines. The double lines have the trend of merging into a dead cross, and the bottom of the small box is around 90350. If it falls below, it will first touch 89855, and the low point below 89855 is 86000. If the rebound fails to receive more than 9.5k, the downward trend may continue to around 86000. If there is a positive stimulus to directly reclaim 9.6-9.7k, it can be determined that this round of correction will not continue downwards. The upper track of this level's Bollinger Band is around 11.3k. The middle track is around 83600. Due to the MACD being far from the zero axis, there is no need to consider it so low for now.

Weekly chart: The bottom of the small box near 90750 of the head and shoulders pattern. If it falls below, look for a level adjustment of the 5-day moving average. The distance from the middle track of 78200 is far away, full of variables, and the direction of the middle track is not a reference for the time being.

In summary, there will be long opportunities near 92000, 90750, 90350, and 89855 in the short term, as this is a round number support level and is prone to bottom-fishing. Spot and futures contracts can be added synchronously. The position here can be slightly conservative, and positions can be added after the floating profit expands.
