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.
Agreed.
Money is money. Even $ is used to buy drugs, weapons and who knows what else.
The solution should not be to mark these coins, so that the 100th person who received it somehow legitimately can't use them. "Simply" the wrongdoers should be caught and dealt with.
