Now I'm just waiting for an update. I've received a physical letter from Stretto containing how much I had in Celsius and the status of my claim appears as "General Unsecured". As I understood it's everything ok and I don't have to fill any other claim. They also mention the deadline announcement (January 03, 2023), although the thieves from Celsius want to postpone the deadline.
Besides that, there is a complete manual with every other details about the claim (who needs to fill it, how to, where to, who doesn't need...), more informations about the deadline, who are the debtors (total of 8 Celsius' companies) and every respective addresses and phone numbers.
I don't know if Simon Dixon on Twitter is being optimistic, but he says we can expect more than 50% of our funds back in 6 months. However, Celsius can't have a reorganization plan permission from the judge.
