Need some insights ?

Hello, hope you're all good , so I have skills in design ,I was doing POD on TeePublic and my acc got down, and I tried Fiverr, but it didn't work.

Now I'm thinking of trying digital products in Etsy. I just want some insights from people who already tried it; I have some questions

Do I need a big budget for it ?

whats some niches that are in demand but not competitive ? Im thinking of including some Moroccan heritage and culture in my products. Do you think that's a good idea

And any advice would be appreciated
