Unless I am mistaken, you would only pay taxes on the gains when you sold. So if you sold under his fund and made a profit, you technically walked away with more money than when you started. It's just that the money came from other investors.
If held in a taxable acct, you pay on dividend income even if it is not withdrawn but only used to buy more shares.
Also, i read that gvmt is trying to claw back money from people who sold before it went bust. Imagine losing some money, and now having to give more back.
