I am thinking of starting to upload content on DLive. Is it worth it?

Well, it is like any post in Steem or in busy. I suppose the only difference is that you do not have to do anything except make the video, put the tags and title. So there would not be a need to write anything. you can just relay on people seeing it and appreciating and it to upvote and for bots to do their thing.

I believe that you are more likely to have your post seen from other platforms like YouTube or Twitch. Nonetheless you can put a video in all of these platforms and get a reward from all of them. And a reason to post on them all is that YouTube does not monetize someone, unless they reach certain requirements them being gaining at least 10,000 views total in your channel, so it would be beneficial for you to post on them all to fulfill some requirement increase your following (fan base) and get rewarded from the head-start.

So my advice for you, is that if you are going to make a video anyways do not release it on Steem, but directly on DLive or Dtube. The reason is that I believe that your post is more likely to be seen by strangers there. Then try also putting your content in famous platforms like YouTube and Twitch to ensure peak gains. Moreover it gain be done as a test to figure out which would pick up steam first and become rewarding.

Hope that you get rewarded for your efforts, and hope that helps you.
