Topic: Block Erupter USB Sales [Temporarily Out of Stock] - page 9. (Read 93208 times)
I'm sorry if I missed something, but can anyone explain what the process is if I'd like to purchase 50 block erupters? I live in the USA
Basically the rest of us buying at the 1.99 BTC price got royally screwed? What a scam, production price is apparently not NEARLY 2 BTC, probably not even 0.5 lol.
You didn't get royally screwed, you got knowingly screwed. From the day these were offered, the discussion was that the ROI on these at this price was measured in years. For you to have missed the 100+ threads/messages that mentioned that is your fault.
What is the best powered USB hub to run 5-10 of these.
Newegg's Rosewill RHB-520 will power 5 erupters plus the Pi. It's got 10 ports, but not enough amperage to drive them all.

Businesses sell products at prices the market will bear to maximize profitability. Production price is meaningless (except it provides a price floor below which selling the product doesn't make sense.) ASICMiner/etc are not non-profit charities.

of course
It was expensive back then, it is expensive now. It is the buyer's fault if you didn't do basic math.
its called profit guys. If youre the only kid on the block selling USB ASICS, you can charge whatever the hell people are willing to pay. That was 2BTC originally, now its 1BTC, hopefully soon it will be 0.75BTC

Avalons, which were break even in production costs: ~$1300 @ 60GH/s
Block Erupter USB @ 2BTC: ~$35000 @ 60GH/s
Block Erupter USB @ 0.89BTC: ~$16000 @ 60 GH/s

I would be surprised if, excluding R&D, this costs $10 each to build and ship. Even at that price it still has way too much overhead (BOM) per hashing speed, so it is hard to think one can have a good deal anytime if a USB miner isn't at least hashing @ 5-10GH/s.

I don't see this address in the OP or sales thread.
EDIT: I can see it in google cache though. Can somebody else confirm this is still the way to get a payment address?

I like the new prices but i expect it drop more with the less ROI we are getting after difficulty changes lately.
Let's do a simple calculation. 333MHash/s can make BTC0.12 per 14-day now.
- the difficulty nowadays changes not in 14-days period, but in 12-days { more precisely in 14/(1+0.13) }. So you can make BTC0.12*(1-0.885^30)/(1-0.885)=BTC1.0168 in one year - no much difference.
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.
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! 
Hello. I have started a group buy CLOSED

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

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

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.
