We reject some business practice in the community, which is intended to distribute the risk and benefit asymmetrically. We are here to change it: we will not accept pre-order forever before we feel logically 100% sure that we can deliver on time. There will be no unexpected waiting and failed/delayed taping-out or any other kinds of delaying risks for our customers.
We also give you a 24 Month Warranty to all our Products.
We created a myth in bitcoin community: no pre-orders and shipping on time. We are earning more and more trust from worldwide customers.
Bitmain also run the AntPool mining pool.
