NOTE FOR POOL OPERATORS: If your pool doesn't appear here please post the pool's statistics as they should appear in the list below.
Why
Ghash.IO is not listed?
Bitcoin ChileProbably because it is a Private pool.
There's nothing private about it. Anyone can register an account on CEX.IO, after which they can mine on Ghash.IO using their own hardware, without buying anything from CEX.IO.
Also, I was pleased to notice Ghash.IO is already included in organofcorti's weekly pool statistics. Is there an API you are using to pull the stats, or do you have to scrape from their webpage?
