lol do you know there is mixer, gambling site who don't take any ID I just send them and they will send back to me in diff wallet address. After that I can sell those easily. And those site not comes into any regulation. Mostly from unknown places and unknown face. No one know real owner.
If tracking bitcoin easy then dark world don't use bitcoin. Ransomware attacker still free even he is attacking since so many months even attacked many govt. offices in world. Why Authority still not able to track them.
I believe you have never heard of big data and big data analysis before right? There are few things,
1. Regarding ransom ware here is one link for you
https://www.cryptocoinsnews.com/bitcoin-seeking-ransomware-scam-busted/2. Regarding dug dealers here is a link for you,
https://darkwebnews.com/bitcoin/denmark-bitcoin-traced-drug-dealer-arrests/3. if you are going to ask why others are not arrested, there are many things at play here(country that doesn't care, state sponsored, etc,etc), this thread is not the place for those discussions.
You say you will sell them easily, how? if you are thinking about skins, game codes, etc, those are still trails. There is no such thing as above regulation, its all well and good till law enforcement takes interest in it.
So I am to believe that people use only anonymous currency for all their illegal activity? if you are so naive to believe that then who am i to say otherwise?
This discussion is now going in circles, just saying mixer, tumbler wont cut it, as there are methods that can defeat those with timing/location/usage pattern/link analysis, search the Internet for BTC blockchain analysis and you will get it. Now either you make a strong case to prove BTC is anonymous disproving all the points that I have said or else this discussion is going nowhere.
