Mainstream sites include like Dailymotion, Vimeo, Twitch, Vevo, MetaCafe (I think that's what it's called) and a few others.
Lesser known and upcoming alternatives are like, PeerTube and DTube, which are both decentralized like BitChute.
Decentralized platforms are the most likely to win out long term I'd say, because people are sick and tired of corporate leash holders. And because of the way they operate they're not prone to social pressure/attacks, meaning they're not as likely to suddenly spring "adpocalypses" on their users or suddenly have random/nonsensical ToS changes.
Mmmm, on a related note, BitChute is also working on a PayPal alternative called PayChute.
