What people fail to realize is that this coin really isn't even that profitable for owners of the B3.  It only brings in about $10 a day.  The benefit of the B3 is that it was only $1600 and it uses 360 watts.  It would take 5 gtx 1080ti's to match the hashrate, making it more profitable to mine something else.  What would really do well would be the v100.
