If you check the news http://bitmine.ch/?page_id=863, you should know bitmine is just in co-operation with some Chinese company. They just bought the chip from the Chinese company and name it as "Coincraft A1" chip. The Chinese company can also sell the A1 chip. They can call it any name they want like "ABC A1" chip. So the question comes: Does the "Coincraft A1" chip means "A1" chip？I don't think so. This is something like Mcdonalds can make their hamburger and KFC can make their own too.

We do NOT buy chips from bitmine and have no business with them.
