Bitmain's 16nm Bitcoin ASIC orders have recently been shifted from TSMC's Fab 14 in Taiwan to the fab in Nanjing, China as Fab 14 will be upgraded to support a 12nm manufacturing process. The orders are expected to begin shipments in May, the sources said.
Read that carefully folks... Order were shifted to the China fab, presumable also a 16nm one. Fab 14 was being upgraded, but Bitmains chips would not be coming from there now, they will be coming from the older tech China plant.
