Bitcoin and cryptocurrency, as of right now, is really making criminals, drug addicts, nefarious beings, and other evil organizations jobs a lot easier.
Yeah?
How is bitcoin making the life of those criminals a lot easier?
Just because of the payments?
Let's take for example the kidnapping part.
So, police can't track the money because of coins, they could of course have tracked the bills...NOT.
But the car used, the phone conversations, the place where he was hidden, where the car was spotted, who rented (owned it), those clues I have the feeling are far more important that the way the payment was sent.
And in case of drug addicts...
What's easier, spot guys with a bag of cocaine lurking around 7/11 and passing the border with a car full of packages or track 10 dollar bills?
Now seriously, what are you trying to say?
