Jullian Fellows, who wrote Downton Abbey, Gosford Park, Snobs and other works, wrote a chapter by chapter e-book called "Belgravia". One bought a chapter each month. I bought two chapters, then waited until the book was published as one e-book. I could not recall all that had happened in previous chapters when the new chapter was available, and the two I bought were separated in my Kindle book list. Most untidy.
I knew Fellows was a good writer because I loved the "Gosford Park" movie and "Downton Abbey". I don't think I'd buy another "chapter by chapter" series again, even by an author I admired. The poor wording of your question tells me you are not yet able to write a readable book.
