Heck. I don't even like Bitmain that much. I really don't care about what happens to the company. I only use the miners because they make the most money. As soon as bitfury gets their heads out of their ass's. I'll buy from them. If the A7 was any where close to being comparable.  I would buy from them. I only care about making the most amount of money so I can continue to grow my mining business.
