What is the source of the BCUs you are trying to sell? You have a pre-order from the group buy and are re-selling?
Because there is no other way to obtain a BCU.
Also do you have your own implementation of Cryptonight Heavy bitstream? Because nobody announced one yet.
I suppose it's xilinx direct, the shipping date is 2019 so this is probably a different batch.
Nocroom seems to be a legit company founded in 2016 for what it's worth. No idea why they would jump on the fpga bandwagon as it's not their primary business
As per all the information from Discord, the BCU won't be sold by Xilinx. It is based on XBB board (production version of VCU) which is not ready yet and when it will be it will have way bigger price than VCU/BCU. The only thing you can buy from Xilinx is VCU and XBB in the future.
