Wester Union and MoneyGram transfers are the most secure thing that you can find in Deep Web. These transfers can not be canceled or disputed by the victim because such transfers between individuals are not regulated by any law. It is like when somebody on the street gives you cash for no reason. Of course he can not cancel that transfer later or go to police and ask them to do that. The police doesn’t even accept such applications. For ever higher security we make only low amount transfers.
