Earlier today I wrote a quick tutorial on how to use golang to track STEEM or any cryptocurrency for that matter. You can find the post on my Steemit account @tenghamn on steemit here https://steemit.com/cryptocurrency/@tenghamn/how-to-make-a-simple-go-program-to-track-the-price-of-steem-via-an-api
The current script is pretty simple and I plan to expand on it to make a tool that will allow you to track any cryptocurrencies along with a gained or lost amount or percentage based on at what price and how much you purchased these coins for.
You can find the entire script on github here: https://github.com/markustenghamn/golang-steem-cryptotracker
