You could make a transaction that turns all your remaining assets into ETH, this will give some cost to the ETH. However, your tax agency may not be so happy about this, so best to check with them on what to do when some data is missing.
Thank you for the support. I have looked more closely as the transactions. I think it has logged the transfer of coins but did not include the information of them being sold for Eth which accounts for the missing Eth History. The balance still assumes those coins are in liqui which is incorrect. Is there a way to fix this?
