Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

i bought recently my first miner the cost =779.86doll for the miner 140doll for the psu 99.5 for shiping .total 1119 doll+ taxes here in greece 360 and the miner gives me each day 0.02 bitcoin so i have to wait over 7 months to get my money back not including electricity. is that right or have i done something wrong?

$780 + $140 + $100 = $1020

But still, you spent $1400+ on something assuming it would make you money without checking the math yourself?

Maybe he will luck out coins go to 600 in the next month and he can sell the miner at break even price.

The good thing is if you get a good PSU you can use it multiple asic generations. So you literally can plug new gear into old gear spots. That's what I plan on doing with my spots of last gen gear. I did not sell PSU's as I re-use them.

Also you can always sell PSU at end if you are not going to re-use. They keep a decent amount of value if a quality PSU.
