A Bitcoin news aggregator site. Once it is set up, it retrieves news from various crypto news sites and post it on the site every few minutes. The site is fully automated and do not need any handling. You only need to manage the ads on the site.
If you are interested then I could make such a site for you.
Does this make any type of income ? Can this be done about any topic instead of bitcoin as well?
Sure, if you do a good SEO, have a high rank and get a lot of traffic then you will be able to make some good money via adsense or any affiliate (amazon, etc)
And yes, it can be done for any niche.
