I bought around 225 awhile back and when I saw it start dropping from 400+I dumped at 375. I'm not 100% sure Snowden caused this, the big pump was on 8/28 and that article (at least one I saw came out 9/29). Still he will draw attention to it - both good and bad.
If a large dark market picks it up like Monero was last year it's going to double. I think it still needs a decentralized exchange too - the centralized exchanges I'm on only allow transfers in and out in the transparent mode.
