I think there is a good chance it will be a while before we see robust dark markets, so there will be a lot of churn and this won't necessarily have a large influence.
Of course this is speculative, but the history is of dark markets (especially leading ones) getting shut down and there is no reason to expect the near future to differ from the recent past.
Hard to disagree with this. When you adversary has a tremendous budget, the cooperation of ISPs, hosting providers, the ability to infiltrate as customers and merchants and never sleeps, it's very hard to operate with total secrecy.To date, most of the busts seem to be centered around administrators with some lax operational security - it's hard to believe that this will change in the near future.
Indeed, it will take some time before truly robust solutions and operations are setup.
The web wallet is a great addition and was sorely lacking. Time to accumulate, I think.
