I bought Cardano (Ada) tokens back in 2017 and put them in a wallet called "Infinito". I didnt check it till now and found that cardano had upgraded to a new wallet system called "Shelley" and Infinto had put a deadline of moving the token from old wallet to the new wallet till 7th July 2022. And in Jul 2023 the wallet has completely shutdown. My tokens are stuck. Am I able to claim capital gains loss on this and what date would I calculate the Ada price for my loss calcualtion? would it be Jul 2022 or Jul 2023?
Thanks
