Of course the black market aspect is there - but it is NOT the only reason
BTC exists and to say BTC relies on black market transactions only for its current value is in fact a very outdated and incorrect point of view.
Silk Road's popularity was about the same when the value was $13 so are you saying all the rest of the increase of the market cap is from other black market activity only?
When SR was down for over 48 hours (and no one knew if it was coming back) it hardly affected the price of BTC at all.
I don't use the service at all but as I actually follow everything happening in the Bitcoin ecosystem I was aware of this.
Have you done a google news search for Bitcoin yet?
EDIT: Here I'll help you:
https://www.google.com/search?hl=en&gl=uk&tbm=nws&authuser=0&q=bitcoinI hope it helps you realize Bitcoin is far, far more than just a tool for the black market. It could be argued Silk Road was important in the evolution of Bitcoin - but now? Bitcoin as a whole has outgrown it and I would argue it is irrelevant as more and more investors and entrepreneurs are seeing the more revolutionary aspects which Bitcoin brings to the table.
