Coupons needed are $300 and up and I would need x2 in order to release the miner. Also willing to pay a small fee for coupons instead if nobody wants to keep this type of "exchange program" going.
Are s7's still profitable or mainly obsolete. I know it depends on electricity. I pay .085 kWh. Is this a fully functioning s7 or one with 2 dashboards?
As a business model, no.
Have 2 left. Currently hashing at Kano with rate in pic.

Sent u a message I'll take them if that deal works for you.
Just got up here after responding to flooding...oy...but wanted to say I've got 3 S7s at the Ice Planet, and they still make money. I'm working on replacing them with 841s, but mainly because I have to replace an existing machine with a better one to increase hash, as they're still out of amps. Not too sure if a higher hosting cost would still be viable, though.
