existence of silk road only confirms that the currency is working. think of it as a proof of concept. without solid independent transaction mechanism and secure protocol underground markets such as SR wouldn't not be able to exists, question whether it's bad or good lets leave for another discussion. illegal markets adopting bitcoin only shows its strength where current system with recent cyprus banks shows fiat's weakness and that it's not safe in banks and could also be devalued by inflating.
fear offers a very narrow perspective on things. you say bitcoin is used for illegal activities - it should not exists. lets also ban cash - the mighty king of criminals, lets ban banks as we see them also involved in shady and criminal activities from time to time.. what's the difference?
bitcoin like anything else is a tool, an instrument to transact - it doesn't kill, it doesn't do anything illegal on it's own. narrowmindness of GFY is astonishing. when you see new currencies poping up you instantly expecting wide adoption and before you buy into it it must be accepted at walmart and everywhere else, else it's not a good currency and the main reason to back that up is mentioning that only underground markets are developed and prosper based on it
