If some certain You-Know-Who organizations/established institutions want to destroy the Bitcoin, shouldn't the most effective approach be......taking out its biggest exchange??
I love conspiracy theories (or hypothesis which almost all are in my mind), but...
It strikes me that the enemies of Bitcoin, so far, could rest on their heels and allow incompetence, naivety, exhaustion, etc to do the job. Occam's razor suggests to me that factors such as these are responsible for the most severe issues...so far.
