Long time since i posted but I have had decent results 1 channel hit almost 500k subs in 12 days 2 channel 3 million subscribers in 4 weeks 3 channel still doing alright at 50k subs p.s this for clients not mine lol

I'm considering starting a YouTube channel and am torn between different niches. I've always been passionate about story animation ex(chainsfr), and I think I could create engaging and informative content around it. However, I'm not sure if it's the best niche for a long-form YouTube channel. Are there any other niches that have proven to be more profitable or have a larger audience? Are there any other niches that are currently trending or in high demand? Ultimately, I want to create content that resonates with viewers and grows my audience, so any advice on what niches are currently popular or profitable would be greatly appreciated. I want to build a brand around this like https://www.youtube.com/@chainsfr ty!
