Beta versions are many times more important than stable versions (they give an edge to those who start early, especially at coin launch time) ... for that you need to navigate and delve into actual slums, i.e. telegram channels full of rude people, non-english text etc, or twitter feeds, etc.
You can parse telegram channels. Would be interesting if you endeavored to do that.
Edit: also, you mentioned push notifications - how exactly?
Thanks for your feedback!
At the moment I'm focusing on the stable versions.
I will keep your suggestion in mind. Right now I don't have the skills to parse telegram channels.
For push notifications I'm using a service from onesignal.
As soon as you visit the page you are asked to allow notifications.
It works on every device and browser but not on iOS.
Unfortunately the majority of visitors so far are blocking notifications.
