If you don’t want others to be able to edit your copy, but make their own copy of the document you can set your sharing settings to View Only. When others open your document, they can make their own copy by clicking on File > Make a Copy. This will make a copy of the file and add it in their Google Drive.
An even easier way is to force them to make a copy in the first place. To do this: copy the link of the doc, sheet, slide or drawing–the one you see when you are editing. When you share the link, replace the word EDIT and everything after it with the word COPY. The user will then be prompted to make a copy of the file.
