Hello. I have some doubts, let`s see if some one can help me.
According this link: http://zetheron.com/index.php/fpga-performance-profit/
There is a limit number of FPGA that can be turned on before the profit became negative, about 25k FPGAs. OK.
My questions:

1. Well, it`s a small number for a big farm. Why exactly this farm don`t monopolize this limit ?

2. In real world, when something rare came to public it`s because it already has been offered to big players and they refused. If so, What they know that we don`t ?
