I was under the impression that in "price discovery" zone, retracements of 10 to 20% are the norm ? If you ever watch a minute or up to a hour chart with M/A's overlapped on it, I think most tech traders watch the 50/200, as soon as BTC crosses one M/A from the top, you can notice tons of tech/leverage traders declare a major SELL signal. If BTC crosses the 2nd M/A line , a bigger SELL signal happens and that's when you see the $5k flash crashes. In a bull, the sharp traders try to guess the flex point and dip buy us to back even on the day.
