The last time I got some official news from the trustee in my mailbox was some years ago. I'm not really sure how they want to compensate those who lost their BTC. I only know that at the time you could proclaim the amount of BTC one lost at MT.Gox and note if you'd liked to be payed back in BTC or Yen.

Anyway, the whole Mt.Gox situation made my quit crypto's for about 4 years. Oh how I wish I hadn't been deterred back in the day.
