In just one week the difficulty has gone up 150% with Grøstlcoin.  Seems to me that anyone buying into ASICs now must be, by definition, hardcore supporters of this coin given that the profitability in terms of investment is now inexorably becoming infinitesimally low.

In time the true apostles will be the ones with their skin $€ cash in the game and those have now become the BK-G28.

God help them all.
