I have over a dozen domain that will most likely will be found out by people wanted to buy the domain by typing it on their browser to see if is available or not or is it for sale or not. The domains are based on a brand new niche only a very few people know right now, and also consist of keywords that will be searched for within weeks by millions of people, because no one has done this yet...until now! However, I already have few domain that is related to this niche that I will be only using to update content and write about the new niche. Therefore, will not need the other domain names for live updated content. Therefore, for an audience like this that are only coming to my website via interest of purchasing the domain name or wanted to find out if it is on sale, what should I do with them? Just park it or sell domain-related software/ebook that will be interested to those audience that make $ via buying and selling of domain names?
If you want to earn money from them, my suggestion is that you must start your websites first. When your websites start getting good daily hits, then you can think of selling the whole website. It would be a better option to start a forum or blog as there are some website buyers readily available for the websites which have good traffic. And if there is any domain that you think can boost your traffic then prefer not to sell it in any case. Keep it for 2-3 years atleast and always keep the website updated.
