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/Posting 2015 article regarding Ransomware. Even last month they attacked very big in so many countries. If that was busted in 2015 how they are
still attacking and getting BTC for unlocking PC.
Regarding drug dealer, 1 guy arrested, there is 1000's or or 10000's dealer there. If they really cracked everything why we are not getting daily news about arresting of those dealer.
About big data I heard about that too and know guys who work on them. It's not magic wands that it will just decrypt everything about btc.
P.S. This is last post about this topic. You did not provide anything solid that BTC is not annoynmous. Some cases there because of user stupidity but if user want it can easily hide.
