When someone buys at a huge percent I think that was a sign of an upcoming price hike but it's odd if you say that it indicates a bear is coming. The price is now bearish because we are still in a bear zone and not because of the upcoming meeting of fed. It was only just a meeting and we don't know what will they talked about. People should not think negatively in advance because what if they lower the rates instead of adding more?
Now I am no way of shorting because I don't believe the price will dump and also this price is too low for me to sell. There are many threads here which talks about if what will be the bottom of the price. You can always refer to that to get an idea if what to expect in case price really bottoms out.
As OP explained in previous comments, it was a joke that went viral on social media. It is a fact and a coincidence that every time Microstrategy buys more bitcoins, it is almost as if the bitcoins will drop immediately after. I've read a lot of such hilarious memes too, and I find it coincidental myself.
The Fed meeting is not only important for the crypto market but it also has a big impact on the world economy every time they make an announcement on interest rates. Bitcoin is an asset, a commodity, a part of the world economy, so its impacts cannot be avoided, every time interest rates rise, the DXY index spikes, then risk assets like bitcoin and stocks plunge.
