Wherever there is money, there is also crime. That has always been the case in revolutionary. The greed of the people is the the problem. It drives one to a criminal action. So it's not just Bitcoin, it's everything else: Money, food, business deals, cars, houses, services and everywhere else where you deal with money. So criminal acts with "normal" money will happen much more, as it happens with bitcoin. The reason: bitcoin is used by less than 1% of all people in the world, so it doesn't happen so often.
And whether we like it or not, this kind of criminal act has no ending story but expect a continuous doing as these criminals and those who are about to start had felt no worries at all. This was found to be normal this time and much easier for them due to new technologies surrounding us and sad to say that even the law enforcers are already involved with this. Definitely yes, we can't just blame Bitcoin for this as this kind of activities been already exist before this.
