In a way, you are right. In can be considered luck that bitcoin and the alts with a decent history behind gathered the initial interest and momentum to become a global movement and that it survived for so long, when it could have been crushed early in its existence, when the space was much more frail.
But other than that, "luck" is very different depending on people's investment strategies, and can have a huge impact or a rather negligible one. And that's true for businesses too, and the way they are built and managed.
