Interesting research coming out of Uni of Cambridge. Can bitcoins be tracked? ... used to have issues with tainting the bitcoins but current technology has lead to practical ways to trace stolen bitcoins. im not sure what this means for you and me, like what happens if somehow stolen bitcoins land in my hands... but interesting nonetheless.
Video: Stolen Bitcoin Tracing - Computerphile; practical way to trace stolen bitcoins Definetly yes!will,according to my experience those stoling bitcoin or another kind of altcoins thats store in your wallet that been hacked is traceable ,but its cannot return back into your wallet,because thats situation i also experience try to tracing those coin was hacking by me,and find out that theres one MEW wallet,who get my coins and to my friends,so therefore i email the MEW support that maybe they can do action,or to do something to return my coins,but they answer me that they dont want to involve about that situation,so therefore the end is nothing happen,and all your efforts and eagerness to return your coins is uselles.
