http://www.zerohedge.com/news/2013-03-10/demographics-bitcoinMany people, including me, are captivated more by the technological aspects of the currency, and how different it is to anything which has come before, more than the black market aspect (myself included).
It is as revolutionary as the invention of the Internet itself, and is the first P2P currency to EVER be created.
Only those with small minds only focus on the black market aspect.
A cursory google news search for BItcoin will reveal much activity from angel investors and legitimate companies doing things which have never been done before.
Stop spreading this trash talk.
