Brings me back to this topic, now we have even more dirty coins after the bter hack. We just have to accept it. Can't go on marking and identifying coins
Bitcoin wasnt created so that certain coins would be marked and what not, this is a part of bitcoin idea,anonimity, so you either accept it or go away.
It is on regulations to rise security needed for people to own and run exchange, even tho i believe theyre lying about getting hacked, and they claimed coins themselves.
cheers
