http://www.pcgamer.com/over-500-million-in-cryptocurrency-stolen/ >What is believed to be the biggest cryptocurrency marketplace hack ever has just occurred in Japan, where digital thieves made off with over half a billion dollars worth of NEM (XEM) tokens, CoinDesk reports. >It's difficult to pin an exact dollar figure on the theft, since the value fluctuates. What we know is hackers stole 500 million NEM tokens from Coincheck's digital wallets. The exchange's president Wakata Yoshihiro and chief operating officer Yusuke Otsuka estimated the loss at 58 billion yen, or around $533 million. Other estimates peg the loss a bit lower at around $420 million, and some have it as high as $600 million.
