So we blame the currency for how its being used, thats a fair assessment.....NOT
I just addressed this question in my last post. The currency is associated with the people and transactions that primarily use it. If a new currency is primarily used or even remotely used for criminal activities it can harm the reception and spread of the currency as whole. It's much the same as child nutrition, failing to feed a child healthy nutrients may result in stunted growth and development, which can not be fixed later in life.
Kinda what I was about to say. Yes, people shouldn't blame a currency for how it's being used, but people will do that anyways. There are a few US politicians that are calling for action against BitCoin, and you can bet they'll be willing to pull any shady looking thing from an unofficial BitCoin forum as proof that BitCoins are the tools of drug addicted terrorists selling WoW accounts to each other. They'll take anything they can twist to make BitCoin seem dangerous, illegal, or childish.
We're kind of getting off-topic, this is mostly redundant, but those politicians are having strings pulled by financial institutions that view a currency like bitcoin as competition. The arguments about why it needs to go away are mostly irrelevant, but the end goal is what is important to those individuals and institutions.
