Interestingly enough, Bitcoin's vitality is still a dazzling fire, depending on the economic fluctuations that the flame can emit or weaken. However, it has never been off since 2009 so far. And the future is elusive, but in general, we should hope for a beautiful Bitcoin era.
I am still bearish about the role of Bitcoin. I am not entirely confident, about Bitcoin usability, as store-of-value or medium of exchange. Bitcoin has diverged from the path, envisioned by Nakamoto.
