The halvening is a momentous event in the bitcoin timeline! Some say its actually a bug (http://www.truthcoin.info/blog/mining-heart-attack/) yet the gold bugs love the deflationary aspect of the reward decrease. Satoshi started bitcoin block rewards at 50BTC for each miner who solves the ever adjusting mathematical proof. In 2013 the reward decreased by 50% to the current 25. See thehalvening.com for clock.

Its as good a reason as any to have a meetup! See you next month fellow bitcoiners.
