Tiktok Niche

Hey! I hope you’all doing good!

What are the best trendy niches now in tiktok ? I have a method that allows me to get videos go viral and reach at least 10k within a month. Faceless content and +1 min. But I don’t know which niche I can do (I can use any video on the internet and bypass the copyrights) ! What do you suggest? I did hopecore bit I feel like it’s so saturated now and dead.. thanks
