EDIT: After further discussion with Phillipma, I've come to agreement with him; ASIC's and FPGA's are "NOT" the answer. Software, is the answer to bring ASIC, FPGA and GPU on an even plain field.
Meet PROG Proof of Work: https://www.youtube.com/watch?v=P6B-ZCyP6K8&tBITMAIN and it's ASIC"s are not the answer to decentralized mining.
I've had my R9 380's mining since mid 2016 and STILL making a profit. My R9 380 rigs are making more profit after power costs than your Bitmain S9's. My R9 380's have ROI'ed 4 or 5 times over compared to your S9's.
In the meantime, BITMAIN manipulates the speculation markets (exchanges) with the majority control of coins they mine annually. They're currently putting the squeeze on all S9 owners by continuing to dump on the market. They're doing the same with Litecoin and L3's. Bitcoin is going down to around $5,380 before you see any reprieve. Then it won't be long before the announcement of a new ASIC to begin the BITMAIN illusion once again.
Most of you with more than 3 or 4 BITMAIN S9's are more than likely having to pay for your power costs as you mine. Not many have the capital to mine with more than 3 or 4 x S9's. They're mining to more or less break even now; while claiming they're doing a service to the network and keeping it secure. Believe me, BITMAIN has enough ASIC"s in their warehouses to keep the network secure from governments. How about keeping it secure from themselves?
In the meantime, Bitmain sells another ASIC (the S9i) as if there's something different and/or better with it compared to previous S9's and the BITMAIN illusion continues to deceive those gullible enough to continue in their insanity once again.
Those of you who paid top dollar for the S9 in December and January are beginning to wonder if my assessment is correct now, aren't you?
