Just wanted to mention that since launching I've been able to add six more fine sources to the roster. It is automatic (i.e. no need to install a new version, content will automatically appear in the main news feed, and the new sources will show up in the source list).
I'm constantly surprised to accidentally discover new sources of good original content; if you have recommendations for good bitcoin or cryptocurrency news sites not yet included, please feel free to mention here so they can be added.
I think with the number of distinct, unique sources surpassing 30 and growing, there will soon be a need to allow users to select preferred sources, or those not to be included.
And finally, if you use the app and like it, a rating/review would be truly appreciated - it is immensely helpful in allowing more people to discover the application.
Thanks,
