> That is profoundly faulty reasoning. For a lot of people, a drop in bitcoin is just a signal to buy because they have an irrational belief that it can never really go down permanently (which, to anyone who remembers 2007, should sound familiar).

Its not faulty at all. When a ponzi stops paying out it crashes. Bitcoin had long periods of not paying out. The never ending demand for it signals the opposite of a ponzi: all assets with demand have a floor where people stary buying again.

I also dont see bitcoin's value as most people. I sold most at 60, figure that out. Who knows where this ends..
