Serious question.
It has been called dead so many times, but I am beginning to think that due to the network effect, vested interests, switching costs to adopting a new thing and the strong trend of adoption, it would take a black swan event to take it down.
It's important to define failure and success here. I know it stands for a lot more than that, but for the purposes of this discussion (to keep it streamlined):
-
I define success as increasing value (price) and not losing too much
-
I define failure as a major sustained loss of value.
For example, it going from $100k to $10k in the next year, then staying around that range for 3-4 years, and continuing a downtrend.
