In today's IOT trends you don't need to have much skill to be honest.
No.1 trending in streaming and youtube at today's date would be Fortnite, and streaming for example Tibia wouldn't get you much. On the other hand if you go along trends, there's no 100% chance you can get solid community along thousand other people streaming and making videos about the same day. I would say you need to be a little original, and make creative content, something that everyone could find their piece of content they enjoy, but nowadays huge percent of community are kids, which has advantage in numbers on social media.
Conclusion : Make content you like, enjoy, and talk a lot, people like me for example, like to sit, and listen to some solid arguments, people that talk about interesting stuff, and they also give u room to think about that, but make your points solid so that they would be like "hey, that guy is right if u give it a thought".
