Looks very cool! How hard would it be to add a feature to keep track of your holdings per coin?

  I was about to add this feature but then focused on API migration for real-time updates. This feature is next on the list :)

Naive question: Why should I use this over CoinCap? I'm running it on Android and it has been a pretty sweet app to keep track of cc
- harshjv 10y ago
  I thought of building this to keep an eye on prices without any efforts from the menu bar. So with no clicks, I can see current BTC price and I can filter out cryptocurrency of my interest with just 1 click. Also, it runs in background so that keeps 1 less tab open in my browser. Plus, I am extending this app to accommodate tracking of holdings, so that would be another reason to use it on desktop.

Good timing, BTC dropped from 1080€ to ~900€ today :-) I don't know if it's just a problem with my windows 10 installation but the currency (USD, EUR etc.) dropdown is not clickable. With tab- and arrow-keys I can switch to EUR.

  I'll investigate this issue and will attempt to fix it. Thanks for trying it :)

  It is fixed in v2.2.1. Thanks for reporting the issue. :) You can get it from here. https://github.com/harshjv/donut/releases/latest https://github.com/harshjv/donut/releases/latest

This is cool, but I wish coincap.io was more transparent about their data sourcing. Which exchange(s) is/are they sourcing from? This data can't be coming from ShapeShift (the owners of coincap.io), since prices on coincap.io are in USD while you cannot trade in fiat whatsoever on Shapeshift.
- harshjv 10y ago
  Thanks :-) BTW you can change fiat currency in the app and on coincap's website as well.
  - bhalperin 10y ago
    Hm, I wonder if coincap just takes generic cryptocurrency prices and converts them at going exchange rates. I.e., the prices aren't 100% tradeable.

Looks great. Just a small question. Where do you get the prices from?
- daveguy 10y ago
  Looking at the source, it comes from http://coincap.io http://coincap.io
  - harshjv 10y ago
    Yep. In older versions, I was using https://coinmarketcap.com/api/ https://coinmarketcap.com/api/ but it lacks proper documentation and real-time updates. So switched to https://coincap.io https://coincap.io

LOL, believe or not I was thinking of building a similar app (only for bitcoin), also FOSS, also simple drop-down from the menu bar with https://github.com/maxogden/menubar https://github.com/maxogden/menubar as base... But my idea included react-stockcharts or react-sparklines... :P
- harshjv 10y ago
  Haha, it happens to me all the time. :p Anyways, this is an open source application. Feel free to add features in it :)

What makes this minimalistic, rather than minimalist or minimal?

  Chose the wrong word from autocorrect suggestions :p Thanks for spotting it out :)
