I don't really get it, if there was a group of 11,000 UFO researchers who called themselves UFORO and spent hours every night searching would they get no article unless someone who did not want to join took them seriously enough to write peer reviewed papers?
I think BitCoin has great potential, blah blah, but that doesn't matter. Thousands of people are doing something that's at least moderately interesting. I can't see what the harm of putting a neutrally worded article in the worlds largest encyclopedia is. It isn't like the thing is going to get to heavy to sit on a shelf.

Bitcoins is the first time this theoretical idea which has been around for quite a while, has actually been implemented. I don't have sources available at the moment, but if I get some time, I'll try to look around. If anybody can find these historical research papers and discussions from before Bitcoin was started, please post links to them.
You can reference them, but they don't count for notability, as they either don't discuss bitcoin itself (and instead discuss the general concept), or they are not independent (ie, they're written by Satoshi).
