I am sure the electric will be paid for , and i wont be paying for it.
but do i know if they wont break? no.
so if i get them for $7,000 thats 1750 a miner. and i see them sell for $3500, so obviously seems like a steal?
That would actually be your best profit, better than mining.
Buy the 4 miners and resell them right away for double the price you paid for. $14000 or 32 Bitcoins, more than you'd probably mine if difficulty jumps are on the higher side. Net profit of +$7000 or 16 Bitcoins on your investment.
Dam, maybe you should just pay me for advising you. Just messin'
