If you check the CNBC mobile app for the last 2 days the bitcoin story/s have been prioritized to the top position or second to the top. Given the frequency of news and the relevance to the cnbc audience it seems to me there is certainly some additional boosting for these to be constantly at the top.

As I write this reply. The bitcoin article is at the top. There are at least 15 more articles more recent than the bitcoin one from 3 hours ago.

Just interesting
