I think this news isn’t that big and I guess people already knew it was coming because that’s partly why Elon invested into Btc.
Also I think there are lots (billions of $ worth) of futures expiring next month (?) and I don’t fully understand it but I believe that when this situation occurs, the price tends to gravitate towards whatever price those futures expire at (which I think is around $45k).
