However, by tolerating criminal activity, against whoever, then authorities are allowing a culture to build up and desensitising the norms as to what is permissible behaviour. Therefore, it is only a matter of time until these types of attacks and malign forces that have been tolerated in the bitcoin sphere, turn their guns on the establishment exchanges, banks, institutions. They play a dangerous game thinking they can allow fires like these to burn only for them.
And what exactly could they possibly do?
Really, the bitcoin ecosystem just needs to step up the quality of their game. Currently they are behaving like amateurs. What does not kill you only makes you stronger and the Bitcoin economy will mature. In the meantime, enjoy the trees getting shaken and weak hands selling.
And this type of cyberwarfare happens against corporate companies all the time. The average cost is $6m and 4% to the stock price.
Not expecting them to do anything or that they could do much besides talking about it.
However, the contrast is stark when there is similar attacks against established institutions it is all over the media and then a few months later some guys in FBI parka jackets frog-march some hapless autistic teenage kid in a hoody out of his mother's basement, and proudly and solemnly declare "We got the anonymous haxor!"
Absolutely the bitcoin ecosystem needs to up its game, and it is doing a pretty good job of improving to each level so far imho. Currently they are amateurs which is why they behave that way ... but still it works.
My main point actually was that if bitcoin ultimately succeeds, then whatever it has had to endure will turn upon established institutions who will look like ripe plump targets in comparison at that point.
