It can be a bad image to Bitcoin, but Bitcoin has always been involved in crimes especially known to be related in Dark Web Transactions even in Craigslist. Ransomware on the other hand created another bad image to Bitcoin but in turn also gave curiosity to many people to Bitcoin, lately I think the timing was good but Bitcoin's price actually increase right after the Ransomware news if I am not mistaken which means Bitcoin still has demand or and increasing one. One bad news won't effect Bitcoin's economy as a whole.
