Are you aggregating news from crypto news sites? If so, they are quite slow and post latest news that have been reported by other main news portals which are already a few hours old. Newsbtc and SeekingAlpha are big examples of such sites. Sometimes they copy news from Cointelegraph or Coindesk.
Also I would like a real time interface, are you looking to sell this? or just develop on this?
I am aggregating news from crypto news sites. Duplicate news is a problem I am running into and am working on a solution to filter out duplicate news articles. At the moment I'm pulling all feeds once an hour. A real time interface would be nice and might be something I'll look into. For the time being, I am looking to develop on this. Also, thank you for the feedback.
