Did the data show all accounts? Many people took all of their coins off the exchange before the collapse.
Nope... 69,000 is the number of people who actually lost money in Mt Gox, and not the total number of users who were active in Mt Gox at the time of its shutting down. Anyway... I myself lost
BTC0.001.
I had a fraction of a coin on there too. I am not even sure how much but it was only $1 worth or so.
In ten years that $1 could be worth $100. I will be so mad then.
LOL
