I am so glad I got out of the mining game and managed to do it at the correct time.
Btw what is the current lowest price for GH/s for a complete product and have we reached the point where the electricity cost has surpassed the mining revenue?
It's getting there if you have expensive electricity.
Antminer S3+, $210 USD, 450 GH/s
income = $2/day
electricity@$.15/kwh = $1.25/day.
I'm not growing my farm now, but the income and spare heat is quite nice this winter.
