OK, my misunderstanding. You need to know your original price (cost basis) for the tokens that were in the investment account. Then, when the bankruptcy case finally settles, you will report a capital loss, using the purchase date and cost basis of the tokens from your own records, and you will use the date the bankruptcy closed as the sell date and whatever you ultimately recover as the selling price. If there is a capital loss, it will offset any capital gains you report for that year, and the remaining loss can be carried forward.
