Yes, it is a sad thing that Bitcoin is being used by the criminals for their illegal activities but we have to consider one thing that the utility of this technology is more than the fiat currencies or any other payment system so it is but obvious that everyone would prefer it over fiat if they are willing to take the benefits of it. There is absolutely zero role of Bitcoin in this crime so blaming it is pointless in my opinion. It's like blaming the internet for stealing money through net banking.
Using bitcoin to pay shows its potential and how useful it can be. But the bad news is that we can't trace it much. I am pretty much sure the hacker is using best ways to hide himself and to hide his digital footprints. Sooner or later he will be caught.
Yes, anonymity gives extra cover to hide and since Bitcoin gives financial ability to make transactions and exchange values without revealing identities, it is one of the favourite modes of payment for hackers. I agree that sooner or later hackers will be in the custody but till then they might expose the leaked data which might cause huge loss to HBO and associated companies. I see this very unfortunate that HBO is willing to pay ransom amount and it is sending a very wrong message that would inculcate the habit of such illegal activities.
