So, we wait for the next chip and launch then
-- Once the stratix and virtex devices with HBM2 hit the market, there's nothing that the coin devs will be able to do. Literally, nothing. by then Bitmain FPGA multi algo miner will be available mining away at all the high profile coins.
I would guess this reason is more than likely why Xilinx is hesitant to let anyone else in the crypto community have their chips. Bitmain is already "partnered" with Xilinx.
