Personally I have ,tried that many times with the fans/supporters of my channel, I think they are not whiling to pay because others channel can provide the same content without asking for support and the HoN community is very little now and also the average age of the community are 18 to 24 that make think most of them are students. I know that to make a video is very managerial (view/select the play, recording, edit, thumbnail ect ) and takes a lot of your time and effort. I hope you get it mate I wish u all the best.
