Crowdfunding can be a great way to sell your book if you already have a following. There are lots of things to consider if you embark on crowdfunding, from logistics to reward tiers. When self-publishing a book, you don’t have many options to get your book to market. If you release an ebook, you sell it through the main online retailers, such as Amazon, Kobo, Apple, and Google. You could sell ebooks directly, but there’s a big advantage to having a global marketplace stocking your books.
