This is my thought as well, and I don't understand why it isn't more commonly stated. The sheer chances that the very first implementation of this technology turns out to not only be viable for long-term success, but is actually adopted as such, seems extraordinarily low.
There's what I call the "football" effect. The player jumps on the football after a fumble, and while he's the first to grab it, there's a handful of 250 pound guys about to jump on top of him.
Bitcoin is the first to the football, but over the long term I think it's going to get inevitably crushed.
