"Every single time I read something about what 'Satoshi Nakamoto' did in designing, implementing and securing Bitcoin, I grow more skeptical that one person, or even a small group of people, created Bitcoin. It is very difficult to believe that something this sophisticated was developed by anyone other than a well financed, possibly nation-state backed organisation." Really, you think Bitcoin is that sophisticated? Can you even point to any clearly stated requirements, constraints, or security definition? The original Bitcoin paper did not even describe the system well enough for someone else to implement it; half the specification of the data formats was in the code itself. Nevermind the bad design; the original Bitcoin paper somehow failed to mention or even hint at (or even use the concepts from) the massive body of related work. All the evidence points to Bitcoin being the work of an amateur, just one hobbyist who hacked together a system based on an idea he had. My guess is that it was a college student who was fascinated by cryptography and had read a few books. This is not necessarily bad -- the same is true of the Linux kernel, after all -- but to claim that Bitcoin is some kind of highly sophisticated system that must have been the work of a government team is just silly.
