Just to give an idea of profitability, before the first batch was released, per day return was around $500, everyone jumped to buy it, hoping to have some profit, but the way Bitmain sold so many units(1st batch), within 2 weeks it went down to $20, even worst they announced second batch with such a low price, thinking that ppl are fool enough to cash on them, end of the day, Bitmain sucked on all the profit and leave the miner, who are the backbone of any crytocurrency functioning to suffer, i have no words. if truly Bitmain was concerned and be part of crypto world they should'nt have released in such huge quantity and made everyone suffer.
