I don't think Bitmain is hurting for money, but I could be wrong.  More people than not say they mine with the hardware and release it to the public once they kill the rate and make money off of them.  I wonder if they do mine on all the machines if there profit is based on the coins they mined or is the 3-4 billion in profit from straight sales? 

 This article from cointelegraph.com (maybe reliable, maybe not) says
"the four-year-old Bitmain reportedly made between $3 and $4 billion in operating profit in 2017, whereas Nvidia, founded 24 years ago, made about $3 billion during the same period. "
