Block Erupter USB Sales [Temporarily Out of Stock]

[CoinHoarder]

Never going to happen. Another month from now when prices are slashed again, because let's face it they have to be, you'll have a few coins and be at a loss on your purchase, even if you intend to resell, but go for what you know...All yor doing is turning a fried cat into a fat one!

I know what I'm doing is risky, but I have a feeling I will make a profit. Maybe not nearly as big as a profit as I said in that post, but any profit no matter how small is... profit.

I also disagree that the prices will be reduced again in a month.. maybe 2-3 months, but 1 month is unlikely IMO.

I will let you guys know how it goes.. you can ride the wave with me. Busto or rubusto? We shall see!

Where do US customers order from?

[Bitcoinorama]

Where do US customers order from?

Look for Kosmo's thread, he sells to the US.

[crumbs]

I just ordered 84 of these bad boys.

My 3 month plan:
Mine with them for ~month = ~$2000 usd profit
Sell on Ebay for ~$150 (half of what they're selling for now) = ~$12600
Cost of 84 = ~84.2 BTC = ~$8630.50
Estimated total income = ~$14600
Estimated profit = ~$5970

You guys are welcome to your own opinion, but this doesn't seem like a bad deal to me.

Granted.. I may not be able to sell them all for $150 on ebay, but even if I sell them at cost I was still able to mine on them for a month for free.  

So, wait, you're getting most of your profit by selling them after a month for more money than you paid for them?  Why mine at all?  Just eBay them as soon as you get them?  Seems like a better plan.

Edit:  As soon as they're sold, rinse & repeat!  PROFIT!

I was looking to buy 50, not from reseller?

[joeventura]

I'd buy 300 but not at $100

I don't need heat sinks, labels, or fancy boxes. Just the cards.

Someone wants $6000 for them just speak up!

Am I missing something? (using 330 kH/s)

Your hashrate estimate for Block Eruptor mining scrypt is slightly off.

Its not 330 KH/s . More like 0 KH/s.

Using this more accurate estimate, i would assume your litecoin calculator should say.

30 days   0 LTC   0 BTC   0 USD

I was, in fact, missing lots!  Thanks all for the feedback...

Okay; 15x the hash power for these other devices, which are a bit cheaper per GH/s.  For these devices to lose money mining (versus electricity), we need the overall network hash rate to increase beyond 100 fold what it currently is now.  At that point, everyone is likely losing money unless someone comes out with a way more energy efficient process.  There shouldn't be any point in the next couple years where I'm losing much money mining with these.  Maybe I'll make $250 fiat bucks back, or $100, or $1000.  Doesn't really matter to me; I'm supporting the BTC network by a decentralized means.

No one can tell what the price of BTC will be in the future, and also what the network hash rate will be in the future.  The price may fall to the point where it's not profitable for large ASIC mining companies to continue their operations mining or manufacturing products (similar to what happened after the 2011 crash), the difficulty could collapse, everyone could start throwing their devices out windows because they are worthless.  I can continue mining and losing a few bucks per month with my little USB sticks at pretty much no risk to me (a cheeseburger a month in power -- who cares?).  Then we may see the price go up in the long term.  One of the best times to be mining BTC before was when it was seldom very profitable by GPU in 2012, because the difficulty kept falling and everyone still mining kept getting more and more BTC; over time the BTC proved very valuable.

This is my high risk investment.  I know I'll make at least a little back, I have no worries about the loss of $500, and I'll be securing the network in the meantime.

I approach this in very much the same way and agree with you for the most part.  But ....  around $50 per GH/s to wait and get it from others or $300 per GH/s (at the new 'lowered' price!) on these USBs is too great a difference to not wait for it IMHO.

Why isn't there a US shipping option for 50 or more eruptors.

If you reach the total volume of 1,000 USB sticks, price is dropped to 0.89 each. We will also pay back the price difference of all your historic transaction (timeline started from the 0.99 pricing) of USB sticks. For example, if you bought more than 1,000 sticks, 500 for 1.99 and 500 for 0.99, the new price will be 0.89, and we will pay you the price difference for the 0.99 USB sticks, that is (0.99-0.89)*500=50BTC.

Sorry for the original ambiguation before that misled some customers that the price difference we pay back is 1.0BTC. What we expected to say is for the price difference based on both new prices.

Can someone help me understand this?
Say I have bought 500 @ BTC1.99 each.
Is friedcat offering to sell me another 500 for a total of BTC50 bringing my total purchased to 1000?

Think what he means is he'll sell you another 500 for BTC495.  So once you buy, you can tell him you've got 1000 total and he should refund back BTC50.  So your order total for the 500 will end up costing BTC445.  The .89 pricing applies only to the usbs bought since the .99 price change.

Clear as mud to me and for everyone else.

You should pay BTC500-BTC50=BTC450 for another 500.

[Exoskeleton]

You should pay BTC500-BTC50=BTC450 for another 500.

No, the last guy was right. 495-50=445btc. 445btc for 500 more units. Quite the deal, and if I had that kind of money I'd take it.

If 15x hash power device were slightly profitable, the USB miners would be negligible then. lol.

The difficulty has to increase by two orders of magnitude for these to become totally worthless in terms of power usage versus mining income.  I plan to run them for the next couple of years.  I'm not really worried.  If they lose money, so be it, at least they're not costing me anything to run and they are securing the Bitcoin network.

The per watt efficiency is similar to other manufacturers out there, so as long as they are mining profitably, probably I will be too.

In the meantime you're welcome to disseminate your money to operations who will ship in "September" or "October" or whenever, who will probably use your funds to buy ASICs, destroy the network difficulty with them before shipping them out, and then send a slightly profitable brick to your doorstop (as we're seeing with Avalon and BFL, and as I'm sure we'll see with the Klondike etc manufacturers).

I am a bit confused by your thinking here.  You plan to run your USB miners for 'a couple years', then turn around and say that other operations will destroy the difficulty and send something that isn't much more profitable than these things in the first place.  For this statement to make sense, the USB miners would have to break even before other ASIC companies ship, which probably isn't going to happen.  For the same cost you can get ~15x the hashpower but have to wait, wouldn't that mean that the difficulty would have to rise even more in order to make those options worthless as well?

Okay; 15x the hash power for these other devices, which are a bit cheaper per GH/s.  For these devices to lose money mining (versus electricity), we need the overall network hash rate to increase beyond 100 fold what it currently is now.  At that point, everyone is likely losing money unless someone comes out with a way more energy efficient process.  There shouldn't be any point in the next couple years where I'm losing much money mining with these.  Maybe I'll make $250 fiat bucks back, or $100, or $1000.  Doesn't really matter to me; I'm supporting the BTC network by a decentralized means.

What is the best powered USB hub to run 5-10 of these. A lot of people seem to be going with the Anker 10 port, but they seem a bit pricey and have heard of issues with USB 3.0. Newegg has a good deal for a Rosewill 7 port powered hub, but the handful of bad reviews make it seem really crappy, and a couple people say it has destroyed devices. Any opinions? I have ran a couple of these just from the ports in my tower but want a fancy hub with every port filled.

[boor]

Let's do a simple calculation.
333MHash/s can make BTC0.12 per 14-day now. Assume the difficulty increases 13% each time (every 14-day).
You make BTC0.12*(1-0.885^26)/(1-0.885)=BTC0.9999 in one year (a geometric sequence with common ratio .885 and 26 terms).  you can break even in one year if the difficulty increases slower.

Last two times, the difficult increases 28% and 24%.

So for US sales, who do we contact to do a 50+ unit order?

 I'm curious about this myself. Can't seem to find a 10 port USB 2.0 hub capable of powering enough of these guys

I am in the same boat as you.  I run mine off a RaspberryPi with CGminer and apparently somewhere in there is an issue with USB 3.0, so I am looking for a solid USB hub that will work.  I have YET to find a good one.  Currently I am using 2 belkin 4 ports that can each only power 2 usb miners   If you find a USB 2.0 hub that looks solid let me know!
