You only view Bitcoin from a negative perspective and don't state the positive one at all. First of all, where you get the data to explain this bad side of Bitcoin? You don't enclose it here? Please show me where you get this news or data related to the illegal activities of Bitcoin.
Anyway, do you think only Bitcoin to use for criminal or illegal activities? NO, mate. Even fiats or traditional currencies are more than Bitcoin to use because they can be easier to use for many purposes. So, if you want to blame Bitcoin, you must compare it first to another one. Then, it can be fair enough!!
