Because so much is going on.
All those companies you invested in last year need funding to do all the stuff they promised. So what are they doing? Selling their holdings into BTC, and then selling the BTC into FIAT so they can pay employees, pay rent, create development, or fail trying.
Couple that with the fact that institutions are leverage shorting the market so they can find reduced entries on massive-volume OTC trades, and bazoom: that’s why the price is going down.
I’m short. I expect $2550-USD before we return to the mean.
