I saw you made few improvement from user's feedback.

- 5 rows looks great, but flexible number of row depending on browser resolution would be better since desktop comes with various resolution & display size.
- Personally i'd recommend https://bitcoinmagazine.com/ for your news source, even though they often make article/report rather than news. You also can check Press boards for reference
- Avoid news sources which often use click-bait, such as CoinIdol (it's my opinion)
