Question to the audience…

Now I looked at the rating of Alpha PAMM-managers. I couldn't believe my eyes at first, started counting numbers. PAMM is in the first place, with capital 167 million. rubles. Looked at the composition of investors – share of the largest – more 28%. Ie. someone invested ~ 40-45 million, in “kitchen”, just one count, it is possible, which also diversified in other councils.
Well, the question immediately arises. How to deposit and withdraw such amounts. Ie. them in parts, on 15 you won't break a thousand. How to show and declare this income? Who traded through “cuisine”, knows perfectly well, that when you withdraw money, they come with the wording “return of own funds”, and when the amounts are relatively small, nobody bothers with taxes. But for such volumes, will surely pay attention. Has anyone come across a solution?
