In the statement of liabilities issued by Mt. Gox after its bankruptcy it shows the following figures as totals:
The statement amount of "Deposited BTC" is 5,202,383,086.88638 bitcoins, which is over 5 billion bitcoins. Since at the time of Mt. Gox's bankruptcy in 2013, there were only about 10 million bitcoins in existence, the statement would seem to be impossible.
Is there something I don't understand about the Japanese number system?
