I get that, but we're drifting off topic. Since the exchange is preparing your tax forms, The question is: How do they know what transfers to the exchange are classified as profit and what's classified as donation? There are no attached notes or memos transferred with the receive addresses.

You have a problem here because you are allowing CEX to do things for you that it is clearly not competent to do. I don't use such methods, but even if I use what CEX does, it doesn't necessarily mean something final that will be presented to the tax authorities.

What I mean is you need to be able to prove to the tax authorities that some of the profit is part of your investment, and some of the profit is the result of a donation, so you will pay the tax rate based on how you acquired the coins. Of course, all these rules depend on where you live, but I would find it very strange if CEX did some kind of automatic report to the tax office and no one asked you anything in the process.
