I think that this has little to do indeed, bitcoin is a new theme for this and too complicated. But soon this, too, the problem also shows up in this sphere of activity. So be on the alert.
For me it is true that many criminls right now is also using bitcoin and i dont really think that police can't stop the criminals to used bitcoin, becauase we all know that butcoin is open for everyone and that is the biggest disadvantage of bitcoin.
I think there are more bitcoin users that transfer their money thru online. Those people can be an investor, a rich one, professional or maybe criminals. We can transfer easily the moment we access our acct. It is very fast and easy, any person can do it.
Crimininal minds goes always for the unseen. From where there act of anonimity is hidden. There they would go. It is a nature and bitcoin fits on all that they need.
From the very start of bitcoin, it is a main issue. I am having a theory right now that everything about bitcoin and its creation have been funded by a huge criminal out there.
Then what if Satoshi has been funded by those all this time. Like every project has a hidden agenda.
The face shows that it is helpful but it has a bad side too.
