If you share DTube Videos,
You should also share YouTube Links, either in the DTube Video Description and the SteemIt Article from the DTube Video, or as a separate Post with the YouTube Video embedded.

Because DTube has a Problem, that it's the only SteemIt Sub-Platform, where Videos can only stay, if they have enough Upvotes.
The more Upvotes a DTube Video has, the longer it will stay. Other SteemIt Sub-Platforms and the Main SteemIt Platform doesn't have this Problem.
Even the Videos with the most Upvotes are bound to eventually be gone and replaced with the following Error Message:

This Media could not be loaded, either because the server or network failed or because the format is not supported
