But you're always in the danger of losing those domains. A lot of people will come and claim legal rights to the name of a city or a certain keyword that they believe they have a right to own the .com for, even if they don't own a trademark on it. Many owners have lost their one-real-word.com's. If you don't do anything with the domain to make a good living that also covers your legal battles, it may be taken from you quickly.
