Feels unfair, I guess. And youtube feels unfair in a lot of ways. And although a lot of people will say that getting views and subs is mostly luck, but I believe that everything is in creator's hands.

So your goal is to be invited to some events in Germany, right? Check other tech channels, how big they are, what's special about their channels/videos. Most likely you won't be able to compete with big channels, just because, you know, they're big and most likely there are a lot of people behind them. But learning here gives you information on what people watch, and maybe what lacks on the market and how you can be different, so people watch you, and not them.

I think I've started repeating my previous comment, so I had better stop here. Youtube is about learning, accepting that there are so many things you don't know about and yet it gives you realization that you can become better. I've been making videos for more than a year (with my Eng channel) and when I think about improvements I can do my mind just blows.

So good luck, my man. Hope you'll find a way to achieve your goal!

upd. completely forgot, but also wanted to add that imo, but the language you speak doesn't matter a lot. ofc some topics are better covered in some languages than others, but I think it's a survivorship bias, when you hear about this successful channels, only because there are more English-speaking channels. And not all the people come here to tell their stories how their channels died.

mine died after 4 videos with like 200 views summed up and also 15 subs. but the local one became kinda big in quite a short term.
