I saw that, and I think Fortress is taking a huge risk with that offer. It's certainly more risk than I'm willing to take.
I don't know anything about the Japanese court system or their bankruptcy laws, but I tend to be very skeptical about these recovery efforts. If I were you I would take the offer from fortress. At the time of the Mt. Gox debacle BTC was worth about $450, so essentially you'd be doubling your money. Sure that's a far cry from $10k, but it's better than a promise from a bankruptcy court.
Best of luck to you.
You mean ~$2500 or so, right? Based on the amount of money/btc/bch there is to distribute in total. Maybe a tiny bit more with bchsv and airdrops. If they're offering $900/BTC, they're probably confident they'll be able to pocket the difference once all the legal proceedings are finished. They are also probably better informed than an average victim of gox-induced permahodl. If the bankruptcy proceeding were to finish within 12-18 months I wouldn't bother entertaining Fortress's offer I had money stuck at Mt. Gox. But longer than that, >3 years as some are predicting, I'd probably rather take the money now than wait. A lot can happen to/with BTC within such a long period of time, the price can collapse by more than 1—(900/2500)x.
