Unfortunately, I stopped my video sites a few weeks ago.
rapidvideo, streamongo and openload shutdown their services because of dcma a few weeks ago. But videospider still works. And you could find other platforms from videospider.
Here are the reasons for shutting down the site.
the most important point: monetizing. I could only monetize it with exoclick, popads and some other cpa network.
I have about 1k ip per day before shutdown. But the income is pretty low comparing with other niche site.
the other point is traffic. Video streaming is competitive in SEO.
Hence I could only drive traffic by auto posting Facebook groups and other social networks. And accounts got banned.
I also buy traffic via other platforms such as outbrain and popads. But it could not cover the cost.
If you have strength in above, I think you could still give it a shoot.
Hope it help and good luck
PS: dcma will be a problem if you host the video on your servers. You need dcma free servers for hosting your videos.
