US and:
Going to put this up here to make life easier then a bunch of PM's asking what I want.  I am asking around 900 + shipping currently.   This machine is over 6.5 S5's in power and more efficient then s5.

Glad to hear another person using them!  They really are a great physical key for security.    I love they they are not tied down to one thing, there are a ton of more things they can do that I scrapped the surface and focused on bitcoin and site security.

Some programs such as Laspass also also allow multiple.  So great to be able to use multiple Yubikeys to one sign-in.

If using it treat blockchain.info as a hot wallet.  There are uses for them, but they should not have a ton in it.  More like daily spend account for BTC.

Also you can add 2 factor I recently went with Yubikey testing it with blockchain.info and it worked great - https://bitcointalk.org/index.php?topic=1353231.0

Teamviewer is easiest and best option if was just him.  I think problem was he was looking into hosting others..... so they it brings up things like this.

I don't see most setting up access for outside world, but guess we will see.   It's a double edge sword as most don't want their miner open to the world, and would prefer behind a firewall.

Congratz Kexkey  on win.  And ouch this one did not go the way I was hoping it would.  +20 is higher then I like to see.

Hopefully next week will be easier, but it's starting pretty strong it looks like.

That is the key on electricity costs.  Those with cheap/extremly cheap electricity are getting S5's at decent deals and can ROI possibly before having.   But takes the right cost, and price on miner.

S7 or Avalon 6 for most people currently.  But still some are set older gear that is good if price is right.

And you really can damage equipment.  I remember the GPU day's very well was very fun mining, but if you pushed to hard you saw this magic smoke puff.  And you heard a noise.... they had amazing RMA policy's at the time 5+ years on some.  But they have tightened it up.

You might make profit on a GPU.  But I don't see making ROI. Most won't even get profit on it even. I don't even put my video cards through the stress of mining at this point.  I took 2 from then and still use them as graphic cards for games.

It all depends on electricity price I would say.  Electricity price can make or break you.  I'm doing some moving around with miners doe to this.  But this 21 cent thread ... 21 cent day's are gone with current products.

So there are still people out there that are able to mine, just takes lower cotst.  And hopefully a little more value on btc would be nice for miners.

My Avalon 6's are priced to sell - SOLD .  With me condensing mining I put it up for around 700 each (selling as pair).  

Great miner's and never over volted.  So hopefully they find a new home .

Thanks it is a good deal as far as money per hash.  I'm still open to taking offers.  It has not sold yet.

Thanks I'm not trying  to get rich off of it compared to individual S5's I think it's priced to sell.... guess we will find out in a few days.

Should have put earlier but item is in US.   So guessing most offers will be US.  But since not trying to make money on shipping I'm not opposed to some other countries assuming buyer pays shipping.

PM sent back.  Still open to buy. 

Going to put this up here to make life easier then a bunch of PM's asking what I want.  I am asking around 900 + shipping currently.   This machine is over 6.5 S5's in power and more efficient then s5.  900 is the 6.5 unit times 150 each (less then going rate).  And shipping I'm guessing around 75-100 depending on carrier.

But feel free to send offers.  If I accept anyone's offer I will post in thread.

I am looking to sell my S5 + miner.   It was a design that has 9 hashing boards, giving it almost 7.7 TH consequently.   It is great if you need a lot of power.   This unit has been well taken care of and no overclocking.

You can see this miner's life through the review I did.  You will see a consistent miner that has history of going a month + without needing to even touch it. - https://bitcointalk.org/index.php?topic=1157426.0 .  Was over 2k, 6 BTC at time of purchase.


Open to offers for it.

If you are 100 percent sure on electricity price you can go used.  I actually am selling some now.   

S5
2x SP20's
3x Avalon 4.1's
And soon a S5 plus model (7.5T).

I think you will find many like me slowly letting go of last gen gear and if you are correct on electricity I would look for deals.

Looking to sell 3 Avalon 4.1's.  Trying to sell as a set.  If you buy all three I will throw in the RPI and usb hub.   PSU's not included in sale.

http://www.ebay.com/itm/Avalon-4-1-x3-Kit-Each-1-25-TH-s-3-75-TH-s-Bitcoin-Miner-Faster-Than-S5-/322001366064?

These are some of the most quiet miners out there.    You can see this among other things in review - https://bitcointalk.org/index.php?topic=1008726.0



So this is the three being ran in review.  They have been treated well and have ran with a underclock trying to get the best price on hash.  But for those of you out there with cheap/free electricity you can crank them up around 1.3T.  The 950-980 GHs range seemed to be best on underclock.

With price of shipping just looking at US sales.  Throw an offer through ebay if interested!

Correct for RMA that is the email to use.  Been a while since I have had to use it, but it should work.

Other option is the ticket system.  But the email seems far more popular.

It does add a physical token to a Blockchain account, which is great.   I have seen how popular it is, that is part of reason I tried these out.

The nano that is kinda the point being so small, so it is meant to fit just in usb slot with a small overhang.  So you are right on that one being very small.  On the other 2 I reviewed you should not be losing them. They are in the same size as a usb drive.   All are slim though where you could slip within a wallet.   They were more designed for a key chain with the hole, but most wallets would likely work.

Exactly it's just a really good product to add a physical layer to your security, which is great.  There are some sites that are related to bitcoin and some that are not that use it, as it is a great tool.   And Lastpass really takes it to a whole new level on regular password security with using a Yubikey with it.

The nano really was my favorite which was surprising.  I thought a full sized on my key chain would be,  But the nano is perfect for laptop use.  You can stick it in the side of your laptop leave it there, and it can only be activated by your touch.  So you can leave it in your laptop if you wanted to.

You must have missed last part of hands on.   Click on the link: https://www.yubico.com/products/yubikey-hardware/

There are many different versions of it.  And the great thsing is you can pick which is best for you.  This could vary for each person.  I thought I would like one of the longer full Yubikey's.  But I ended up loving the nano version, it's fit with a laptop is just great.  But for everyone it could be different.

Not sure why you would want to get off eBay.  Go direct link I listed above and by direct from manufacture.  I just like buying direct on anything dealing with my security.

It's a good idea and the combinations you can do are great.   I have found Yubikey and Lastpass to be a huge changer in my online security.  And sites that have Yubikey integrated like Blockchain.info are great.

I was always pretty good at not using the same password.  But my passwords were no where near as hard to crack as the Lastpass generated ones.  These would take a bad guy a lot more time then standard accounts to crack during things such as a database being taken.

I really think Yubikey with it's layer of physical protection is a great thing in any case.
