On the same day (24th), we found out large discrepancies between the amount of cash held in financial institutions and the amount deposited from our users. The amounts are still under investigation and may vary but they approximate JPY 2.8 billion.
We are investigating the causes of these problems. Since there are probably a variety of causes including hacking by third parties, we need to investigate a huge amount of transaction reports in order to establish the truth. As of this date, we cannot confirm the exact amount of missing deposit funds and the total amount of bitcoins which disappeared.
Once we discovered that bitcoins had disappeared and the discrepancies between cash funds and deposit balances, we judged that it would be difficult to continue our activities normally and we therefore closed our site at noon on the 25th (Japan time).



OK. So as a financial guy.....Here is my question.  It's one thing to get hacked and lose 100s of thousands of BTC.
How is the CASH on the 24th missing?  Shouldn't this have been audited on a daily basis, a weekly basis perhaps, but certainly on a monthly basis.  To say OOP...we lost 2.8 JPY is the most troubling thing here for me.
