I had a significant amount of Bitcoin in a BlockFi interest account. I lost access to those assets on November 12th, 2022, and they filed for bankruptcy shortly after.
At some TBD time in 2024, I will receive a cash payment for a portion of the value of my BTC at the time they froze my assets. At what point can I get a tax write-off for those assets, and at what value (Bitcoin is currently worth more than 3X what it was worth on 11/12/22).
