so we now at bitcoin mining cost of 100$ from miners need to dump 3600 coins asap everyday to cover their cost? 

$100 is just electricity. ...
That's why I agree with Elwar--there's a much greater profit margin for small miners vs megamines.
Can megamines buy gear with mom's credit card & set it up in mom's basement (where electricity is free)?
Hell no!
How is NotLambChop so consistently right and everybody above Hero has him on ignore. I think we are the have-nots here, folks

college students also get free electricity.... but they are seasonal workers
