Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
Numbers are currently crazy since BTC is stagnating for almost 2 months after "yearly dip", and then "Chinese new year dip". Maybe numbers will change if price goes up. But difficulty increase is killing everything 
Ya man, takes at least a good 12 months to roi and by then the btc mined will not be able to pay for power in average home based mining.
