Three methods to lock in the bottom points of this month's big BTC pullback:

A. Currently within the 20-day adjustment range of the 45-day line adjustment cycle, near the bottom Bollinger band at 80085. The 20-day EMA is 52, corresponding to a price of 74965. Therefore, after breaking 80k, lock in the bottom: 74965

B. The 45-day line level has a death cross, with the middle Bollinger band at 77250.

C. The 0.618 pullback position at the 45-day line level:

126208-48888 = 77,320

77320*0.618 = 47,783.76

126208-47783 = 78,425 (the golden ratio pullback point)

PS: Adding the lowest point of April 7 this year, 74666, which is very close to the 20-day EMA of 52. Therefore, it can be predicted that the bottom range in December can be locked in at these three points: 78425, 77250, 74666.
