I would like to suggest that the exchange has some section which will allow for it's users or traders to easily file for their taxes with all the proper forms available for them to do so. I know that many crypto investors and traders have been faced with the challenge of correctly filing their tax returns with many not knowing how to do so in the first place.
Having some kind of a feature which can track and appropriately store trading information so it can easily be accessed later will be of a great help to the majority of us, your users. This can be data which will easily be copied and pasted to the corresponding tax forms.
