Most of WafflePool's variance seems to come from Litecoin mining these days - profitability peaks and valleys particularly when we have good/bad luck at finding litecoin blocks..
Yup - and now Alpha-t says they are going to up their promised MH/s to match competitors (aka KnC). This is going to be an interesting year for scrypt for sure. I wasn't expecting 100MH devices until sometime next year.
Does this mean we have a year of gpu mining at best or is there more time?
I wasnt mining yet back when bit coin was gpu only so i dont know...
