What do the mean by probe in past transactions? Does it means we will have to provide them all details of our trades and bounty rewards too?
Apparently yes if you receive a good amount of money during the exit window. So you will have to justify the source of the money and how you have earned them. It can be signature campaign or bounty rewards or even the gain from trading. So start tracking everything so that you can provide all information whenever needed. If possible, start converting your crypto holdings into cash asap. Because once the ban is announced, it will be hard to find traders in p2p exchanges. It's better to be safe than sorry.
But most if us have participated in so many campaigns over past these years. It is impossible to keep track of all of them.
Also as you know how crypto trade works. We buy sell buy sell so many times that it is such a tedious job to get all that info.
