It was recommended on No. 3.11 at the same time as ach. At that time, key was 0.083 and now it is 0.0923; at that time, ach was 0.029 and today it exceeded 0.04. I will continue to hold these two. When the key is reduced by zero, a part will be released, and the rest will be released around 0.12. ach wait until it doubles before taking it out.
