Where 2008 fits
Why 2008 is special
2008 is the year credit stopped. Lehman Brothers failed in September, triggering the deepest financial crisis since the 1930s and bank rescues across the world. In October, six weeks later, a paper describing Bitcoin was posted under the name Satoshi Nakamoto — a sequence often noted, though the paper's connection to the crisis is asserted more often than evidenced.

Related numbers & connections
The flash crash came two years after the financial crisis and raised a separate question — not whether markets were mispriced, but whether anyone was in control of them minute to minute.

Lehman Brothers filed for bankruptcy on 15 September 2008; the Bitcoin white paper was posted on 31 October the same year. The proximity is often presented as cause and effect, and the paper's own text does not make that claim. The genesis block does contain a headline about bank bailouts, which is evidence of timing rather than of motive.
