Thank you for that, but it would have been great to change the method from a specific date instead of a tax year. Because this method is applicable when you move from a country to another. You rarely move on the 31st of December.

Thank you

This should be a given. You don't want to have to amend your tax returns due to Koinly changing the cost basis in a prior year that was already filed.

we'd save on taxes, and they'd save server resouces by not having to recalculate past years for every transaction mod.
