How to Become a Bestseller With eBooks?

Do you think you can make it big just like J K Rowling by publishing ebooks? If you publish an ebook on Amazon and it becomes a bestseller, you can earn well. That'll not only make you famous but also earn you a lot of money. But how likely are you to become a bestseller with ebooks? Do you think you can earn as good as writers who publish in the traditional market (print books)

I think regardless of printed books or ebooks, to become the bestseller, the content of your book matters the most. What you write needs to make readers find it interesting to read.
