There hasnt been a crash, its just the fluctuations. If you look at the long term chart its just a detail;

Very possibly true. Or some other govt agency, or combination of agencies.

I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party.
Clearly mentioned "I" as opposed to "we". The first bitcoin version 0.0.1 had 51 files, of which about 31 files are code. The c++ files contained a total of 11901 lines of code, c++ header files (definition files) about 7919 lines. A total of 19820 lines of code, it is not impossible as a one man project; I found an older version with about 5 files, which date from 15 nov 2008. Earliest message was on 2008-10-31. The paper has about 9 pages. Id say this is not impossible to do in about a month or two month period.
Al tough lines of code are a bad measure for productivity, lets do it anyway; Say you write 500 lines a day, you'd have 30.000 in 2 months. If you are working with 10 guys 500 lines of code per day seems feasible, it would be 300.000 lines in 2 months. If it was a team of 10 guys.. then what were they doing in all this time?
In addition, when you put a lot of people together you get a lot of discussion about how things should be done, developers have strong opinions. So a time larger of 10 or larger is very very unlikely.
There are a lot of clever people not working for the NSA, dont be mistaking, it is possible it was not developed there.
