so... not a wise price.

Open with something less than the expected ROI and you might get some interest.. I'll keep eyes on in case you shift to open at a lower number.

Hello !

What's the wattage of all these ?

Hello, the wattage is about 400W x 21 = 8400W

Because this auction did not receive bids  I am restarting it and editing the OP.

Your prices are quite high.

Did you check out bitmaintech.com?

Its 0.885BTC per 180 GH.

for 55 BTC I could get 62 of em or 62*180= 11.160 TH

So explain your pricing?
Also these are 360 Watts each and more power efficient.

The market value is roughly about.

11.16/8.5=1.313

Taking 55 BTC/1.313= 41.89 BTC.
Now since antminers are more power efficient and can over clock to 200GH.
Your true market value is around ~35 BTC or so.

No one will offer much more then that.

BitMain is out of stock btw

I'd just like to state that antminers are not more power efficient than bitfury chips. If you do not overclock them the bitfury rigs will draw less power. These are messy and not as reliable though (finicky and need to be tuned and also maybe babysit it once in a while). Having said that they are only worth it at the right price.

As someone else already pointed out, Bitfury's chip is more efficient than Antminer's. On top of that, machines are not overclocked nor optimized but still output 8~8.5 TH/s, there is room for improvement.

That is a beautiful masterpiece of cables.  I would hate to have to take it down to ship it. 

How in the world did you get that much amperage out to your front porch?

Did you unhook your Dryer and put a 100amp breaker on it and then run an extension outside?  Or do you have extension cords running from every outlet?

Still even if its more power efficient, it still doesn't justify 55 BTC+.
Id still prefer the extra Hash-rate of antminers.

I may understand an offer of 40 or so BTC, but not 55+.

26 BTC

I had some technicians do the work for me, they modified the electric panel to ensure it would not burn down. Plenty of electricity available here.

Please confirm you are a serious seller, 55 BTC has no possible return of investment for the listed hardware.
