Unless you just heard about Bitmain last week and/or this is your first miner, don't complain. A miner that has absolutely no ROI estimates is obviously a gamble and if you buy it, your are gambling. Even it Bitmain gives batch 3 away tomorrow, no one put a gun to your head to make you buy the first batch.
Yes, Bitmain's interest is to make money (not for you BTW), but cast the first rock he who's not here for money.
