It is profitable based on that calculator. But... We never know how many rich kids recently contracted manufacturers to make ASIC Miners for their own consumption. It may or may not make you a profit.

Being in that question means that you are having a little bit of a dilemma on this. One thing is for sure, you got to decide and make it now, whether to order or not.

2 things could happen:

1. ASIC Miners give up because of the difficulty and profitability (Difficulty Reduces = Scarcity Reduces = Price Decreases)

2. More Miners join the fray and cause to raise the difficulty to MT. Everest (Difficulty Increases = Scarcity Increases = Price Increases)

Or could be a mix of 2.
