Hi,
I'd like to draw your attention to very simple and easy to use Python3 based script for switching between multiple algorithms / currencies / pools based on current profit reported WhatToMine.com.
The project is available on github:
https://github.com/gozwei/pyMultiMineReadme and example are provided.
I have been using it for few weeks now and works with no problems. Let me know if you have any questions or comments!
Have Fun and make money
