Whatever the reasons you state and the case studies you present at this point, I still assume that Bitcoin is still alive and will not die even if it doesn't move PoS.
The downward graph seen in Bitcoin is normal in my opinion and not that it is a reason to say Bitcoin is going to die. Because Bitcoin can still increase again if there are more people who make purchases simultaneously without selling more. That's why I never pay attention to anything that other people say about Bitcoin's badness, because I still don't think Bitcoin is going to die.
