Which camera / facecam would be enough for streaming on Twitch?

I would like to know which camera would be enough for streaming on twitch?

I don't want to spend more than 150 euro on a camera.

and which camera would be best for twitch streaming that is good but also cheap?

Every webcam over 30 euro provides sufficient images. It doesn't matter. You're in a little window.

Standard you can throw Logitech C920 into the room.
But you can also start with its C270. It just depends on what your expectations are. But would pay attention to at least 60 FPS here.

It's about that you can see me in the stream and it doesn't jerk or something.

that can only be on 480p

Every 20-30 euro webcam is enough.
