Re: Incoming Avalon News 8/9/2013

It's quite laughable, 4PH/s of obsolete 110nm Avalon chips with no chance of ROI, probably wont even cover power costs.

Don't be ridiculous. It's going to be quite some time before Avalon chips can't cover power costs.

17.9 PH @ $100 exchange rate & $0.10 per kWh. It could happen mid next year. If you believe some of the "exponential growth forever" kids it will happen in 10 weeks or some nonsense.

Don't forget to double your electricity costs to allow for the air conditioning. If you have to hire even a single staff member to run the show, their wages would buy a lot of electricity. Data center space is not cheap either.

The article also said Bitmine were in Hong Kong where the electricity is way more than $0.10 per kWh.
