<prompt> Human: Edit: To clarify, Im not asking how to access the coins I already can do that. Im asking about how I can deal with the tax side of things since I have no records of acquiring them.___Im afraid that if I just sell them, Ill somehow get in trouble with the law. They were bought years ago between 2012 and 2015 by Cavirtex, which was a big Canadian exchange at the time. Cavirtex was acquired by Coinsetter a while back. And Coinsetter was acquired by Kraken. I would love to pay tax on it, but I dont remember what they were worth when I bought them, especially since they were bought in dozens and dozens of transactions over those few years. Is it possible to over pay the taxes so that if Im audited, I can just say I dont have the records but made sure to over pay so that Im not evading taxes? Paying more than I need isnt something I want to do, but its preferable to just letting these bitcoins rot awayIm in Canada btw  <response>: Its like a virtual version of finding money in your pants pocket, only better. :
