Updated- 6:36 pm Philippine time: We included the statement from Mr. Lon Wong, president of the NEM Foundation.
Tokyo.ย Popular cryptocurrency exchange site Coincheck is temporarily suspending trading ofย XEM (NEM).
Coincheck halts NEM Trading
Coincheck announced on its blog its decision to restrict NEM trading after reports surfaced of deposits not being reflected in the users’ accounts. The initial advice is to refrain from depositing XEM in user accounts.
The exchange site further released a statement around 12:38 pm (JP Time) asking everyone to also refrain from trading XEM. In a matter of minutes, the company raised its warning, advising users not withdraw XEMs temporarily.
When inquired, Coincheck’s only response is that users wait for an official announcement soon.
Responses
Blockchain expert Mr. Koji Higashi noted that all altcoin trading is halted at Coincheck, although bitcoin trading still continues.
There is a rumor that coincheck, the biggest crypto exchange in Japan, has lost up to 600 million USD worth of XEM in a hack. But it's not been confirmed officially yet so be warned about FUD and misinformation until the details come out. https://t.co/fduwzCt01E

Initially, XEM deposit/withdrawal was suspended. Now they have stopped withdrawal/deposit of all coins as we as JPY and trading of altcoins altogether. (BTC trading still alive)
Not sure what exactly happened but this is not looking good so far.

Meanwhile, according to Mr. Ichiro Yamamoto, a famous writer from Yahoo Japan, Coincheck should have recognized the incident by 2:00 pm because they contacted the NEM Foundation around 2:40 pm (Japan Time). Mr. Yamamoto noted that other coins have also been stolen and that NEM is currently investigating. The article did not clarify which coins are being pertained to.
Coincheck Not Yet Licensed by the FSA
Since Coincheck is not yet licensed as an official virtual exchange by Japan’s Financial Services Agency, there is a question of how the investments are secured if an emergency event such as this one occurs. However, Coincheck notes on its security page that the users’ย bitcoins are stored in cold storage. Without an official explanation, users are left guessing as to what exactly happened.
As of press time, the value of NEM has dropped as per the data from Coinmarketcap.
Evidence
In Japan, users began noticing that their XEMs are missing from Coincheck:

For the user above, he wondered why there’s only 1 XEM in his account. He’s supposed to have 500M XEMs in his Coincheck wallet.
Users Reported of Lost XRP Too
Users are also reporting of lost XRP, the currency of Ripple.

Japanese crypto exchange Coincheck halts withdrawals, deposits, trading in NEM. Rumors is a big chunk was moved from their wallet. Also seems >$130m of XRP moved out too. I called Coincheck, but they wouldn't answer questions and asked me to email themhttps://t.co/BMJk6DpkZO https://t.co/oo6p1YSuRZ
