As others have indicated, you can’t copyright an idea.
However, you can still gain traction by fleshing out your idea and creating a good business plan. Even if your idea is already established by someone else, you you can still be a competitor. Copyrights are only truly valuable if you have a unique product which it’s not clear if you do or not.
I would encourage you to focus on developing your idea for a business and then making it just a touch better than the rest in the industry.
You could probably benefit from talking to a copyright attorney (to see if you have grounds for obtaining a copyright once you actually create a product) or a startup attorney if you want to learn more about developing your business.
