While the momentum has turned somewhat in bitcoin’s price (upward), the sentiment among the public still remains quite negative. Still waiting for the event that marks a shift there, could be anything like another corporate treasury allocation or a nation state strategically buying or even something we haven’t considered. But NgU is a very powerful force.
Discussion
I think corporate and state buying won't be disclosed. They don't want to drive up the price, after all. Anyone who announces their big purchases to media is just trying to drive up the price, which means they are going to sell, which means they aren't "serious" (see: Elon).
Large enough companies to matter acquiring bitcoin will almost always have some disclosure, I agree government entities are likely to keep quiet.
My point was more of a price momentum argument. Whatever the number is 2x 5x or 10x more interest next cycle it will do so with less liquid supply and be faster and more violent than before.
