Report crypto transactions without the history
I have made a few USDC deposits into the Celsius platform and it has been earning weekly interests in USDC before the company went bankrupted. I have not been manually tracking any of these transactions and now I cannot access the Celsius platform app anymore.
Am I eligible to report all the deposited USDC funds in this platform as a capital loss? If so, can I just report a total loss amount since I no longer have the individual transactions?
