51% Bitcoated Gold Attacked ... Some exchanges have lost millions of dollars
The malicious miners used a 51% attack to unload about 380,000 bit coin gold (about 20 billion won) from the exchange. In this case last week, the suspect who attacked secured 51% of the hash rate of a particular block chain over a short period of time. He seems to have made a double payment payment to the exchange and withdrew all the bit coin gold since the deposit was confirmed.
