This historical behavior, to me, implies two things:
1) For cryptocurrency as it is today, even "stability" sees 20% fluctuations.
2) Months-long periods of this "stability" are normal; not everything is boom or bust.
That reminds me of a meme someone posted in WO. It was a picture of a very old man with white hair and a beard, and he was saying, "Who said trading Bitcoin was stressful? I'm only 23, and I feel great!" Hahaha.
