I have something similar.
The issue with your file is that the most profitable coins are NOT on what to mine
So it is a good IDEA to add your own algos and calculations. It is quite easy to connect to blockexplorers API to get the hashrate and also add price API from coinmarketcap ( if it is listed) or even better right from the exchange.
Requires much more manual work though
EDIT: I also think your nethhash24h calculation is not entirely correct

New to this stuff. You might be right about the calculation. Going to each block explorer to get info would be a huge job though. Any hint, I would take.
Thanks for the comments.
