There's a lot of stuff that I do not know here. That must mean I'm no Bitcoin maximalist.
Topic added to my Watchlist anyway.

Do you know of any reliable site that monitors hashrate and mining difficulty only? i was looking for something that is light or easy to load.

Do you often use gobitcoin.io? How often does it go down?
Preev.com is a good converter too but it goes down sometimes.
