WOW B1 is sold out. I'm surprised people are actually paying that much for 2Th. Oh wait... no I'm not. Plenty of retarded people out there in crypto land.
Seeing as people paid 1.36 btc @ $600 btc price for 2 antminer s3's......
Why would they not pay less for more hashrate and lower power requirement?
BTC ROI depends on Bitcoin Difficulty and/or BTC price.
So time is money, that time It was affordable but this time its not.
It gets trickier now because power costs and mining efficiency are becoming equally important factors to consider.
