The current pattern is looking like an 'M' top. The measured targets for a lower price move are marked by the red lines. It doesn't mean the price can't move lower than those levels. But They are good levels for closing shorts, taking profit.
At present BTC is respecting the long term log channel from 2017. Current momentum suggests the channel is unsustainable, therefore I propose another channel of equal height is entered to the lower side. With a possible bottom highlighted by the yellow line.
