Difficulty has gone up 25x. That means that device is even less profitable now than when he made that comment.
True.
BFL is so late that their devices will never ROI.
Hogwash. My 2x $1300 SC Singles are quite likely to return their purchase price in a few months.
Not hogwash.
If you don't have them already, then it is like saying *when* you do get it, it will produce $2600 in a reasonable period of time.
Take into account that the amount of profit in each subsequent month deceases by a significant percentage point. So your ROI gets longer and longer each day you don't have it in your hands and turn it on to starting making your return.
