With a regret I state that today's rate of GB does not profitable production.
Benefit turns out only 0,0112 BTC/GH/day over 0.026BTC/GH/day in alternative X11 Coins.
And if to try to sell at least a daily profit, to discount will constitute up to 50% of current price.
If developers in the next weeks the network and a coin do not give news of GB stimulating value (to 1400-2000 sat) that
will just die.
