Fuck Bytom and Bitmain. They worked together to scam thousands of us for millions of dollars with the B3 and their shit coin AI ASIC blah blah blah. At this point I don't care if the laughable 500 BTM my B3 has mined drops to nothing and it probably will.
You need to look into the mirror for blame. You bought an asic for a new coin in which you had no idea if the hashrate it provided was good or bad. You need to be a more informed consumer.
