Btc has been tested for 3 days, and the main force of the long and short has completed the layout. The war is on the verge of exploding. At present, both sides are prepared to be very full. As a general investor, it is recommended to keep a wait-and-see attitude, maintain our 6400-6800 judgment unchanged, and adopt a breakthrough follow-up strategy. Trading point: The probability of an upward breakout is still large, but it must be clear that the downtrend line is on the stand; shorting is a break below $6,400.
