After long and not a very hard thought 
I dropped my royalty from 25% to 14.9%.
I will report to you back if I start selling anything, I decided to test my own theory and see if the lower prices due to lower rate will result in more sales and more customers. Feels good like a spring cleaning. 
I wouldn’t drop your prices across the board. I’d do some A/B testing instead. What that means is that you design two products that are essentially the same. Then you list one product at 25% and the other product at 14.9% to see if either of them get sales. Try this with a few products then analyze your results. If the lower-priced products still don’t get any sales, then review and revise your niche, the product title, SEO tags, and design. It could be one of these other items — or a combination of them — that are preventing you from making sales. If you just do a sweeping price change, then you won’t have any real sales data to analyze.
@Jadendreamer13 Great advice, thank you so much. I like it, makes sense to look into products title, tags and design. And drive test two similar products :D.
I like how quickly you learn and take action. 
@Jadendreamer13 Thank you, it’s fun to learn from good advice
