(4) lower degree is at 3K. So after rebound (which could be either wave (1) of ((5)) or just wave (B) of ((4))) there always will be two possibilities:
a) Drop to 3K (probably with whole stock market in global crisis) and then slowly growing to 100K (probably after 2022)
b) grow to 100K without dropping to 3K. This scenario will be confirmed if new ATH in place.
So I will sell some at 11K-16K. I will lost growth from 11K to 20K, but if new ATH in place, I would rebuy some being more confident that no drop to 3K ahead.
