25% is taken by curators. After that Dtube takes another 25% of the author rewards so its not the same as just doing a regular post on Steemit. I just found out about the other apps doing the same but I believe they have a lower rate. Dlive is the only app not taking anything for posting. Nevertheless I am rooting for Dtube's success. I just would like the information to be transparent. We have a lot of new people coming on to this platform and they should be able to know this info without having to dig.
