It's kinda hard to get the API-What sheet updated. It doesn't stay couple seconds without many #ERROR cells (WTM JSON problems, i guess). =/
It is my understanding that WhatToMine API is not as robust as an Exchange. They also want to avoid others to capitalize on the work they did. I try to limit my Altcoin to the one that are worth looking after.
How many altcoin do you monitor right now?
I'd like to have a comprehensive sheet with most possibilities. So I've created there 60 lines(altcoins) to monitor. Isn't there any other place we could get info besides WTM?
