How to track multiple bitcoin addresses?
usually you can use block explorers to display amounts of your different bitcoin addresses. I tend to go to "blockchain.info". As it is cumbersome to cut and paste everytime, I created a small (Linux/MacOS/OpenBSD) shell script to do this for me (https://github.com/pebwindkraft/ccy_values). There are payed APIs and non payed APIs, the latter one having a limit on requests.
