They do all the work. It's fair and was transparent from ICO. I would be more concerned if they only wanted 10%. I would ask myself why would they go through the trouble and risk. Right now Taas is on track to provide another nice dividend. People think of Taas like another crypto but that is wrong. Where it's closed fund it really shouldn't have the volatility of other coins which in most cases have value based on speculation. Of course this is all my opinion haha
