Loss in profit under this contract
At 0.001 BTC/Ghs a 30% difficulty increment average will never have a breakeven point.
At 0.001 BTC/Ghs a 25% difficulty increment average will never have a breakeven point.
At 0.001 BTC/Ghs a 20% difficulty increment average will never have a breakeven point.
At 0.001 BTC/Ghs a 18% difficulty increment average will never have a breakeven point.
At 0.001 BTC/Ghs a 15% difficulty increment average will never have 147 day breakeven point.
At 0.001 BTC/Ghs a 8% difficulty increment average will never have 88 day breakeven point.
