this coin cost less than mining, difficulty changes in a strange way can be a kind of error of a multipool that dump at those prices ?
Yes, buying Dopecoins from trademybit is much cheaper then electricity cost used to mine them.
Why do they lose money doing so? Someone of Dopecoin team pissed his admin so bad that a war is started. Little problem, we are 50 people mining dopecoin, they're over 500.
They removed the % comparative, but I took screenshots of them mining at 38% profitability (this means 38% of LTC, not of the current best scrypt coin).
LET ME UPDATE:
ACCORDING TO THEIR WEBSITE THEY'RE NOW ATTACKING DOPECOIN. They're making 0.0184 BTC/mh a day.
MINING DOGECOIN OR GPUCOIN WOULD GRANT THEM 0.0581 BTC/mh. They prefer losing 70% of their sales.
