Just weeks after Korean crypto exchange Coinrail lost $40 million through an alleged hack, another in the crypto-mad country — Bithumb — has claimed hackers made off with over $30 million in cryptocurrency.

Coinrail may be one of Korea’s smaller exchanges, but Bithumb is far larger. The exchange is one of the world’s top ten ranked based on trading of Ethereum and Bitcoin Cash, and top for newly-launched EOS, according to data from Coinmarketcap.com.
