Bitmain sells specialized mining hardware. They never made claims regarding the profitability of the hardware they sell. That's up to YOU to decide based on your OWN due diligence and circumstances before you choose to invest in a HIGHLY SPECULATIVE venture such as ASIC mining. Bitmain never twisted anybody's arm or told you you should buy it. You made that decision on your own, apparently based on just the foolish assumption that just because the other ASIC miners Bitamin sells are currently profitable, which has absolutely NOTHING to do with the miner you ordered. Doing even some basic research regarding the coin you were  planning to mine, you would have realized you were taking a big risk and now you are paying the cost for YOUR poor decision. You have NOTHING to complain about.
