None, unless you have a series or at least several other books. BTW, you can't sell a free e-book, only give it away.
Why a lot of people's are selling Free eBook?
You really might want to rewrite that sentence so it makes sense. Yes, I know what you're trying to say, but if you want to be a writer, you absolutely must be able to express yourself clearly. Otherwise, what's the point?
Giving your book away for free using the KDP free download promotion option gets your book read by folks who would likely never find it otherwise. It's true that some of the free downloaders are merely collectors and never get around to reading the books they download, but the rest of the people do read what they download for free.
For new writers who don't want to spend gobs of money on advertising and promoting, giving the book away temporarily garners readers. It's a fantastic way to induce readers to sample your wares.
Despite what some of the other posters believe, my experience has been that employing the free download promotions has over the past four years built up a small group of folks who enjoy my writing style and are willing to purchase some of my other novels. I would never have accumulated those "fans" without the Amazon free download option being available.
Good luck with your book.
