From what I learned in earlier posts, mostly parsing json from an API endpoint, I created a simple command line program that tracks any cryptocoins and their respective values, you can input the price and amount you bought it for. Colors can be turned on or off, the update interval can be configured and you could have as many or as few coins as you would like. See it in action here:
