Nice idea. I was ready to suggest to display the tweets (positive or negative) so we get a better idea about the score but it's already in.
I would suggest improving the UI/design, don't take it wrong I know you just started and I am not able to do better btw.
Maybe in future, you can add a page presentation in the menu for each exchange?
Q: are you using something like Microsoft Flow?
Thanks! UI updates are coming, it's currently basically just made for mobile screens. It's a lot faster to create a design that is usable with every screen size and then reiterate for desktop later.
Do you mean like a screenshot of the exchange's homepage with "page presentation"?
This is the first time I've heard about Flow, looks like it's a Zapier copy? It would probably be easy to hook up the Twitter API with those tools, but I like to run everything with Node.js so I feel like I'm more in control.
