What are the pros and cons on writing an eBook versus writing an hardcopy? There were times I wonder this about an eBook, how would the author know that after an eBook is purchased by a customer, the customer simply won't just let the eBook to others for free? Thanks.
People can give away a hard copy book as well. Of course, an eBook could be copied multiple times and distributed online for free--people do pirate eBooks and make them available to others. You can use Digital Rights Management (DRM) software to restrict this, but it is not foolproof--someone with the right knowledge and tools can break through the protections. However, generally speaking I don't think this is a big concern for authors who are just starting out, especially if self-publishing. Getting people to find and read your work at all will likely be a much bigger problem than people distributing your work for free.
Most authors write both it’s not really a concern to be honest most people don’t want to faff with sideloading an ebook to their e-reader to save a couple of quid
If you're going trad, it won't be your concern or your decision. Your books will likely be released in both formats. If you're going self-published or indie, going the e-route is the only way to make money.
your writing is copyright as soon as you write it - in terms of registering the copyright the process is the same whether its ebook or print https://www.copyright.gov/registration/
