Your best bet is to make a plan and critique it heavily. I personally haven't followed any of your stuff outside of the Steem Blockchain but you seem like you have a lot to be able to talk about and it's also entertaining. There's a window of opportunity at least within DTube where if you plan to grow as a content creator and increase the quality as much as you can before this platform becomes well known, you'll have a community behind you. For instance your VLOG's which talk about the Steem Blockchain was unique. It gives value to Steem. So as a news personality for Steem, I would 100% say that would be a really good direction for yourself.

So really you're going to have to figure out if you feel you can support Steem because after that, the rest becomes a lot easier. I personally feel the best content will always get known and you've clearly understood that with well made Thumbnails and titles. From there, it's about making your video content as great as possible and if you do that, I personally feel you'll be on this platform for god knows how long.

Goodluck!
