Bitdock - Track cryptocurrency price index in the MacOS menu bar

Bitdock is a lightweight OSX menu bar application that tracks the price index of Bitcoin in USD, GBP and EUR. I built it after being tired of constantly heading over to Coinbase or GDAX and I was unable to find an OSX application that was simply executed. I bodged this together in a few hours, so I'll be improving and adding new cryptocurrencies.
