"The best way to make Bitcoin fail is to believe that its success is guaranteed [...]
That is a really good way to put it.
I believe that Bitcoin will give me success but we still need to manage our expectations as our expectations would be the one to kill our hopes of success. If we expect that bitcoin will give us huge profits in only a short amount of time and it doesn't meet these expectations, we will think already that bitcoin has failed.
I don't also understand the world play there, but it looks contradictory. How can one fail if it's successful already? Haha, but BTC is not new anymore and we already witnessed its performance through the years and by there, we can say that it is really successful. Future is only unpredictable but if in case there are things that can affect it negatively, I won't say that it is a failure. It is not its fault nor its founder and we can just accept it.
I guess it's wrong to use the word bitcoin in this statement but what I really mean and what OP means I am assuming that a person can either succeed or fail by investing in bitcoin.
If you invest in bitcoin and you made the wrong choices then you fail to make profit, most people would think that bitcoin is a scam then since they initially thought that they would immediately create profit with bitcoin but they weren't able to create profit. Which is totally their fault
Besides my image of success for bitcoin is when it is already adopted worldwide and not only by a few countries which we ae going towards to but still has not reached.
