Can you help here? It says GH/BTC 0.0747 what does this mean? 0.0747 GH/s for one bitcoin or 0.0747 bit coins for 1 GH/s?
In the forex world, X/Y means the price of X in Y. It is an unfortunate standard created by people that obviously don't know math (which is ironic). So, GHS/BTC means price of GH/s in BTC, and the cost of 1 GH/s is 0.0747 BTC.
