Hello everyone,
I seek some advice from experienced authors on Themeforest. It’s about how you plan a strategy to make sales, regarding an item conception?
Maybe some will not be willing to share some secret strategies 
but I want to know how to choose the right niche at the right moment, before it gets crowded with quality or non quality items. Do you have a trick or some particular advice ? Example : how the guy that created a killer crypto design is flying with 380 + sales with a newborn template ?
Any thoughts ? All are welcome, and thank you for your time.
