Shorts got wiped out: BTC rose 13% in four days (Sep 17–Sep 21) and broke above $87K.
The most direct driver: the US and China are heading to talks and signaling goodwill. Gold fell and money rotated back into risk assets. Add shorts forced to buy back, and the price kept climbing.
Even more important is the money: price moved first, then ETF money followed, with nearly $1B flowing in in one day. Institutions are back. Bitwise's CIO put it bluntly: the crypto winter is over.
Two levels to watch: hold $90K and the next leg could start; lose $83K and reduce your position first.
Long or short, there's opportunity here. Go straight to BingX
