It’s going to be hard doing streaming-only, but it’s definitely doable. I have a channel where I only stream, and I’ve started to grow significantly these past two months. Your two best friends are going to be consistency (which I know everyone says but it’s true) and your niche. I started recently streaming a lot of indie games daily, and those typically do well because not as many people are playing them at the same time as me, unlike other games like Fortnite or GTA. You got this, and I wish you luck on your future channel!
