Logic dictates that the fall of the Bitcoin by $ 1000 or -10% is a good trade. And the zone 8960-9210 should be strongly defended by bulls, because earlier there was someone who bought BTC for 3 months. And the "chuyka" suggests that if the bears are in a serious mood, they will break the price of the cue ball below 8900, and there stops and a strong strait in panic down to the zone 7860-7900.
