After looking into bitchute, their terms, their communications, we found that there were many unanswered questions. The bitchute team does not ensure that the videos are stored in a safe place. In fact, there are no reasons why it should not close like vidme.com. People should be cautious when they upload their videos and always keep a local copy of their videos. There is no private organization behind Bitchute that could ensure that this service is sustainable. For now on, Bitchute has no sustainable way of making money.
It could be stopped at any time and Video makers who hosted their videos on bitchute could lose all their videos in a blink of an eye.
It is not decentralized because there is a copy of the videos somewhere on a web server. When a video has no views. There are no other locations for storing the videos except if someone has stored the video on the computer and distribute it thanks to WebTorrent.

It looks like bitchute is made to lure people into downloading
For people who don’t have money and aren’t ok with the youtube policy, it is a good solution to distribute their video content. For other people who look for an alternative to youtube, I would suggest hosting your own videos.
As per 2018, looking for a sustainable Youtube alternative is a waste of time
