Stream Twitch in which language?

I want to stream on Twitch soon, but can't really decide on a language. I would like to stream either in German or in Russian. In German there would be no problems in Russian either. I have the basic knowledge of the language but not as fluent as German. I used to watch streams in German for about 4 years now I've switched to Russian for about 2 years, so I've been on Twitch for about 6 years. I myself have been Germany since I was 7 years old, I mainly speak German, only with my parents and a few relatives Russian. I would only stream Russian to speak the language more and because I myself find the language interesting and want to master it better, but I wonder if you would watch someone who can't speak the language fluently. What do you all mean? Am I worrying too much about that?

Give it a try with Russian. You will see how it goes down and you can always change it. I don't think your not fluent Russian will be a problem for the audience. They can also watch you become safer and better.

Just try it out.
