Locke2005 shares a report from CNBC: Hackers stole several hundred million dollars' worth of a lesser-known cryptocurrency from a major Japanese Exchange Friday. Coincheck said that around 523 million of the exchange's NEM coins were sent to another account around 3 a.m. local time (1 p.m. ET Thursday), according to a Google translate of a Japanese transcript of the Friday press conference from Logmi. The exchange has about 6 percent of yen-bitcoin trading, ranking fourth by market share on CryptoCompare. The stolen NEM coins were worth about 58 billion yen at the time of detection, or roughly $534.8 million, according to the exchange.

Locke2005 adds, "That, my friends, is the prime reason why speculating in cryptocurrency is a bad idea!"
