Not sure about the 8 reasons why BTC will fail, but the question to the OP, can also think of reasons why it will not fail as well?

Bitcoin has been with us for the last 10 years, and if there are chances that it will not succeed, then it should be in it's early years. And it almost happen, many early adopters quit and few of them really stay. But still even if the disappearance of Satoshi, the market continue to thrive to where it is right now.

So to say that there are reasons now for Bitcoin to fail? it could be just pure hatred on it, in my opinion.
