There are a lot of articles on the Cryptoknowmics portal. Even more that needed and more than you can read. Are there any filters?

Some smart filters or hashtags would really be great on CKM, for example on its news feed.

They have filters...You should look better. For example, Bitcoin filter: https://www.cryptoknowmics.com/crypto/news/bitcoin/

It's not a filter) It's only an example of news categories.
