A few weeks ago (Dec 10) I bought a 20 port usb hub from buyahash.com. It said (and still says) it is on stock. But since then I heard nothing from buyahash. My order is still in "processing". I wrote tons of emails to get the status of the order but noone bothers to answer.

Is this company a known scam or is it just their usual way to treat customers?

Ever since BTC price came down end of November I have been waiting for big miners stop or at least reduce their mining. I just cannot understand how they can still be profitable by a price of about 700 usd. They need special facilities - I guess normal data centers won't cope with the heat of hundreds of Th hashing away. Their mining equipement is useless/too-power-hungry after 6-9 months use. There won't be many tech guys to get for the sysadmin jobs. Most of the hardware is not standard data center stuff. All this sounds overly expensive to me.

I do mining as a hobby. Electricity is not that expensive for me and cooling comes free 9 months of the year; I just open the window most of the time. I resell mining equipment after about 3-6 months to buy new stuff. But at the end it will never make the same profit I get from my IT day time job.

What is the thing I don't get? Why do they add and add more mining power although the btc price is about 700 usd?

Hi,

I have four Bitburner Fury boards that work just fine. I do run them with cgminer options: –avalon-options 115200:32:10:50:256 –bitburner-fury-voltage 950

But no matter what I change with the voltage options all bitburner boards run with 1150 mV and hash about 46-49 Ghs. I really like to bring hashing down to half that number - underclock it. I guess that can be done using the options but I cannot figure out how the equations works. Can anyone point me in the right direction?

And if anyone wonders why I would underclock. The fans get quite loud in our small condo and my wife isn't that happy about it. So either underclock or turn off at night 

Bis vor einigen Wochen habe ich diese kleinen USB Bit Erupters an einem 49 Port USB betrieben. Strom hat der Hub über ein normales PC Netzteil bekommen, indem man den Mainboard Strom Anschluss (24 Pin) anschloss.

Jetzt habe ich mehrere Bitburner angeschafft, die direkt am pcie Anschluss betrieben werden. Die bekommen aber nur dann Strom vom Netzteil, wenn ich etwas vom am Mainboard Strom Anschluss (24 Pin) laufen habe.

Kann man das irgendwie ändern? Wie macht ihr das?
