I have really simple answer for this, in my opinion there are many people who are just video content creators, so if you upload your video to Dtube then that will include all video content creators, and if you upload it to Dlive then you can cover all streamers too and if you upload on YouTube and then if you share that video through Steemit then it will cover everyone else so it's not an bad choice to upload all three platforms to cover all type of audiences. Keep up brother. Wishing you an great day. Stay blessed. 🙂
