To be honest i am deeply disappointed by Antminer B3 and Bitmain. I think that is it for me and i am stop purchasing any of antminers and i think i give up on mining. The crypto world is very tricky and i think that the best money making is from buying coin and hold it no matter what happens for 1 year or so. I paid 2800$ for antminer B3 and i didn't even get 200 bytom for almost 2 weeks of mining. I don't know what to do. Thanks to low power consumption i will just pay the electricity and hold the coins. That was very painful to watch others gathering 2000+ bytoms just in one week when i just can't get 200 bytoms for 2 weeks now. Hope you best guys who has B3 and are in same position as i am. What a scam was that from Bitmain. Hate that kind of treatment the batch 2 was realesed very soon and my antminer was delivered way too late, even batch 2 was delivered sooner than my antminer from Batch 1.
