I’m looking for a software to track crypto taxes for many years. How does Koinly track cost basis consistently across years?
In other words, if I first use Koinly for 2019-2020 and choose HIFO before paying my taxes, are those entires in the cost basis “crossed off” in calculations for the next year? When I then pay for 2020-21 taxes, will it choose the highest transactions that aren’t used in 2019-2020 as the cost basis?
