Actually this is wrong. Basically he would be much better off if he had demanded cash, this way we can clearly see where his money is going. I'm also going to assume that he isn't proficient in using Bitcoin so it will be easy to track him.

btc does offer them a convenient way to operate.
Cash is a much more convenient way in some cases as it would be harder to trace.
Exactly what I was thinking. Cash would be much quicker and easier.
How? Bitcoin is faster to travel around the world without the need of a third party. Don't we advertise this, then why is that when criminals use it we say that cash is quicker and easier?
It's not, cash is bulky. If a criminal were to ask for ransom in Cash, they'd have to define a collection point then someone from them will have to go there and physically pick it up and that could lead to getting them trapped or traced. With bitcoins they can sit in the farthest corners of the world and receive it there within seconds, whether they can get traced with blockchain tracking or other means is another matter but Bitcoin is convenient and criminals will use it.
But that being said, it doesn't mean that it is bad and it should be blamed, if bitcoin wasn't there, criminals would have used some other way and even if they had received the money they still would have blown the place. In the end people have to realize that it is a faster more convenient technology, like emails, and it is going to be used by criminals and good guys but just because email can be used to transmit encrypted secret messages between criminals around the world, it shouldn't be blamed for the wrong doings and just like that bitcoins shouldn't be blamed either.
