jimmothy,
Currently, our business is focused on the industrial-scale miners, hence we only offer chips and boards. Because we offer boards with many different interfaces, the PCIe card is also suitable for the consumer market, where we believe preorders give us a way to allow those interested to get early access to the hardware and also gauge market demand for our products in the consumer space. We understand the sensitivity around pre-orders in the consumer market and hence are not actively promoting any pre-sales.
