Bitcoin is more like TCP/IP rather than a Western Union that should be supplanted by a Venmo or whatever. At this point I think the only thing that could "kill" Bitcoin is ignoring it. I find it very telling that the most convincing bear scenarios are from bitcoiners. In any case, I'm aligned with the principles within Bitcoin, and if we're wrong, at least we tried to change the money. That's more than what most other people can say for themselves who instead choose to succumb to fatalism
