 ;D

its an paid webhoster also.

i got 1 also now. exitet

What is a block eruptor ?  I see all these little usb devices for $60 or thereabouts.  Are these things legitimate mining platforms?  Or is there some other function?  I just see mention of them... haven't seen a good page explaining it.

They are ASICs (Application specific integrated circuit), which can be used to mine all SHA256 coins (Bitcoin, PPCoin, TerraCoin etc.) ... The will yield about 330-335MH/s like a middle class GPU

What is the max m# a usb device can put out ?

Currently around 330MH/s  :)

WARNING SCAM

THIS WEBSHOP ONLY OPENED TODAY SO IMPOSSIbLE THAT ANYBODY ALREADY GOT THEIR ITEMS:
https://bitcointalk.org/index.php?topic=267285.0 (https://bitcointalk.org/index.php?topic=267285.0)

FAKE!

Thank you Finalize!

It's been online for a little longer, according to the person that started that topic.
So that does explains the ordernumbers that have been quoted in this topic and the fact that people claim to have recieved ordered items.


I'm not gonna say it's not a scam because there is no way to check wether these people are actually speaking the truth, but it does supply a viable explanation.

Does anyone that has recieved his/her order still have the packaging? Specifically the shipping label?
If anyone would be so kind as to make a photo of the item and a photo of the shipping with his/her forum username written on (and personal address blurred out ofcourse), it would definately add to the credibility of this new shop.

That way, we can confirm the address in the contact details of the page and have (to some degree) confirmation that orders are actually shipped.

Oh, and could a moderator maybe take a look the IP adresses of the people that claim to have recieved their order, and crosscheck that against GeoIP to see if they have a high probablility of not being affiliated?

our webshob got online early 2013 and its still in the final process with suppiliers.

but yes you could order items since the first day of the shop.

we had 84 orders since this time and everyone has get the items they ordered.

Bitueuo24

You registered just today  ::)

i made a screen of my invoice for everyone who think its a scam.

http://i39.tinypic.com/351isub.jpg

anyone can shop an invoice.

Ok, thats a step in the right direction.
However, I'd like to see a paper version of it, or even better, the shipping label that was on the box with your forum name written on it and the phone next to it on the table.

A screenshot is fairly easy to photoshop, and a real photo is at least hard enough to provide some degree of confirmation.

I'd love to believe that everyone has recieved their order, however, I don't think you can ship and deliver within 24hours.
I've been watching your website, specifically the block erupters and since yesterday the stock has gone down from 40 to 36 34 already.

Can you tell us what the ordernumbers from the last 24hours are and wether those are already shipped?
Do you have tracking codes on your shipments, so people that have ordered the last 24hours can track their shipments and confirm it here?
Just send the tracking number to the email adress they provided when ordering. I see that it's required on your site, so you should be able to do this.

i did not find the package and the invoice i will ask my gf later when shes home, maybe she took it away.

but i can make a image of my galaxy s4 with my forum name tagget on it if you guys like


thats all i can offern right now.


i startet the topic coz i wantet the ppl to have some cheap stuff and now we talking about scamming -.-

:D

stanley

I'he heard that changing the software of usb miners can increase the perfornace twice! Is it possible?

No

Are you sure. The guy has told me that is honest.

so many alts being made to try to get people to order some erupters  ;D ;D

nice try OP  :)

when you say it.

my scan of that box cover from my pack. thats all i could rescue.

after that im out here, to much stress for me i just wantet to help out some guys with cheap stuff.

http://i41.tinypic.com/v653t4.jpg

i want to know too that whether this is really legit.

Stanleym stop creating so many alts xD
You're wasting your time

Any reason why this stanleym (very recent member), that is posting these scans, has in his profile the address of the same site he is saying he bought the galaxy on? I was willing to accept that the site was legit, but using a promoter/alt/whatever to post scans as if he was an uninterested customer looks untrustworthy.

All those scans were horrible as any sort of evidence of a storefornt being legit.  Sounds like the guy got tired of photoshopping.

i dont promote anythink. i just tought that site is cheap.

you guys asked for prof .

I understand you want to help us to get a good deal and I really appreciate the effort.
However, in the Bitcoin world there are a lot of scammers. Since this shop is just very new, it's nearly impossible to tell if it is a scammer or not.
We, as forum users and potential buyers, just want to know wether this site can be trusted. That's why we, or at least I am, try to confirm it.

This, No.
Yes, we are sure.
And yeah, Everyone that says something believes in what they say and says they are honest.

ASIC's cannot be reprogrammed. They are pure hardware that are designed to do task X. In the case of Bitcoin and some other alt-coins that would be SHA256 hashing.
There's no software inside those things, so there is nothing to reprogram so there's also no way to increase performance with software.
However, you can modify the hardware. Specifically the clock crystal. Stock it should be 10 or 12Mhz, but there are people upgrading the clock crystal to a 16Mhz one and increase the input voltage of the ASIC by swapping some other components out. This does require external power, since a USB port will not be able to provide that amount of power, and ofcourse, more power in means more heat out so it will need better cooling.

Just think of these things as hammers. They can only be used to hit things. They cannot cut, since they are not a knife. And there is no way to turn a hammer into a knife by just reprogramming it.
That's more like it, however, still no forum name written on ;)
Please, just put the phone on a table, put the shipping label next to it and write your forumname on the shippinglabel. Then take a photo of it and post it.
Handwriting is extremely hard to photoshop and having some textured surroundings and light influence makes it even harder. That's why that would be considered good proof.

I get "Error establishing a database connection". Not very professional

This "newbie" forum is interesting.
It should be renamed to "scammers".

It's a strange place where real people HAVE TO be tortured before being allowed to escape to the real world :D

If you are looking to get scammed, use this website. All of these new forum alt accounts vouching for this cheap looking website just look bad.

Stay away.

i dont think its an scamm. i ordered there got recipe + invoice and my order is now completet.

@ bitueuo24, I could come around your shop and collect the items I want to buy and pay then. I could verify that you site/shop is legit and goods are actually existing. The only way to prove that you are not a scammer is to let someone visit your business and get a proof. Otherwise people will have doubts and will not trust you with their money.

There are only newbies replying, I checked the website and you can only pay with bitcoins which are non refundable if something goes wrong.I also checked streetview and eventough the picture was from 2008, this particular house is not usable without heavy modifaction as a webshop/warehouse. I wouldn't use it. Why won't you accept creditcard like a regular webshop?

The other thing is that address from contact page points to a different company. See below. More I look into it, more things looks not right. I think is another scam. Do not trust them!!!

greetings finkle

I heard they can be used to mining other coin too

Block Eruptors are USB connected and powered devices that are designed to do just one thing: create hashes based on the SHA256 algorithm.
They can do anything that uses the specific subset of SHA256 (SHA256d specifically) that this thing can calculate.

We, as miners, use them to mine coins. Any coin based on SHA256d will work, but you could use them for other SHA256d cryptographic purposes, like password hashing, brute-force password cracking, creating an encrypted data tunnel (VPN), SSL-like certificates, encrypting Word documents or Excel spreadsheets, etc.
You just need to develop a piece of software that will send any encryption commands to the Block Eruptor. For a VPN, you'd need to create a piece of VPN software that will push all transfers through the Block Erupter before sending it off through internet.

So yeah, they can be used for any purpose that requires SHA256d hashing. However, software to support that is yet to be developed.
As soon as Block Eruptors become obsolete, it'll be more likely that someone actually will develop software like that.

Edit: it really does nothing more than hashing in SHA256d.
Think of it like Ceasar Cypher. You take the alphabet and assign a number to every letter. When you send a message, you change all letters to numbers and the reciever has a conversion table.
Anyone in between cannot read the message without the conversion table. If the mailman opens your envelope, he cannot read what's inside unless he is in posession of the conversiontable or spends hours (or even days/weeks) trying to decypher the message.
So the Block Eruptor is essentially nothing more than a sort of automated conversion table device. It will encrypt and decrypt a message.

that address label looks fake.


do not trust this site..... probably that europeanminer scamming dude back to get more btc

99% scam... free webhoster and only noobs are confirming it's not a scam..  Sorry to judge but in my opinion it's not safe at all.

This time, there is a fair chance that the sale was real, because the poster is also selling erupters (https://bitcointalk.org/index.php?topic=224256.0), from the Netherlands (not Germany) and more expensive. He didn't realize he is helping the competition. But the Op (and his alts/promoters) real need to change their advertising methods.

Can anyone tell me how much at the current difficulty these eruptors are mining in bitcoins?

I think .6 is a fair price on BTC Guild but I would like to make sure it won't be 5 years before seeing anything come of it.

Also this would be strictly hobby use. Not looking to get rich.

You'll probably break even within the year. Some expect several months, others claim over a year.
Assuming .004BTC per day as raw income, you'd break even in 150 days at the current difficulty, which is about 5months.
Scratch that, I've done the math... read on below.

However, people seem to expect a 20% increase in difficulty every two weeks, so income drops 20% every two weeks.
So here's a table, assuming perfect 24/7 availability (no pool downtime, no computer downtime)

2w period	BTC/day	2w Total BTC	All-time Total
1st	0.004BTC	0.056BTC	0.056BTC
2nd	0.0032BTC	0.0448BTC	0.1008BTC
3rd	0.00256BTC	0.03584BTC	0.13664BTC
4th	0.002048BTC	0.028672BTC	0.165312BTC
5th	0.0016384BTC	0.0229376BTC	0.1882496BTC
6th	0.00131072BTC	0.01835008BTC	0.20659968BTC
7th	0.001048576BTC	0.014680064BTC	0.221279744BTC
8th	0.0008388608BTC	0.0117440512BTC	0.2330237952BTC
9th	0.00067108864BTC	0.00939524096BTC	0.24241903616BTC
10th	0.000536870912BTC	0.007516192768BTC	0.249935228928BTC

So that's 140 days, and not even close to 0.6BTC.
Depending on how much electricity costs, it may not even pay for itself.
However, the price for these things is just simply affordable now, and electrical usage is near nothing. Rule of thumb here is that a 1watt device, running 24/7, will cost €2,- (or $2,50) per year in electricity. It's a little high to allow for price fluctuation.
So an Eruptor, 2,5watt each (5V x 0,5A = 2.5W), will cost €5,- per year to run. And just extrapolating the above table will tell you it will make more than it will cost in electricity for a long time to come.
I believe that electricity in the USA costs less than half what it costs here, so it'll be profitable for far longer.
When your investment has returned completely? Not within 6 months.

Ofcourse, this does not account for overhead powercosts. A PC, RaspberryPi, etc is not included.


Edit: I've extrapolated it in MS Excel. 52blocks of 2 weeks (so 2 years), will yield 0,279997442372135 BTC
After 29 two-week periods (or 58weeks, a little over a year) the 2week income will drop below 0.0001BTC  that would be less than a single cent per 2 weeks (at 1BTC = $100 exchange).
Daily income will drop below 0.0001BTC after 17blocks (or 34weeks)

Ofcourse, this is purely based on speculation that difficulty will rise 20% per two weeks and that your mining income will drop by the same amount.

Edit2: Extrapolated through to 4 years (104 2week blocks), income total will be 0,279999999976638BTC
If the difficulty only rises by 10% per 2weeks:
after 2 years, income total would be 0,55766224756596BTC, drop below 0.0001BTC/day would occur after 72weeks
after 4 years, income total would be 0,559990240917066BTC

Edit3:
Factoring in power at €5 per year and 1BTC = €100,-, it would become unprofitable after 66weeks @ 10% diff increase per 2weeks.
At 20% diff increase per 2 weeks, it would become unprofitable after 54weeks.

this

Nice post.

Thanks guys :)

Moral of the story: If you are in it to get at least a return-of-investment ratio of 1 (make everything back, including electricity) just forget about USB Eruptors at their current price.
If you are doing it as a hobby, by all means, do it. It's a fairly inexpensive hobby and a good low-cost way to support bitcoin for the coming 6 months or so.

If prices drop below, lets say 0.3BTC it would be rather interesting and should provide a ROI-ratio of close to 1.

yeah tought this also

i just got my erruptor also

i got my 5 usb miners today yay!

Nice :)

Would you mind to fill my request earlier in this thread and confirm that you actually recieved your order?
Just put the ordered items on a table and put the box with the shipping label clearly visible next to it, photograph it and post it here. Ofcourse, you are allowed to smudge out your own address.
The more textured the background and more well-lit (not washed out and unreadable ofcourse) the photo, the better.

I am willing to buy all the available erupters in the shop (currently 19) if I can pay on receipt / escrow. As a trusted member I'll post on receiving the items.

Alternatively I can pay with a reversible method, like credit card, if that option is available. I trust Graet and John K.

will definetly do that when im home again.

so is this a scam or not?

since i got my stuff and several others its not. but i dont say order there. all i can say is

couple months ago i ordered there a tv and 5 days ago the usb miners and i got them delivered.


will post pics wehm im home

Don't know whether the shop is legit or not.
But anyway, a USB block eruptor at 0.6 BTC will not be profitable given the current difficulty trend.
Look at my calculator at www.coinish.com/calc/ (http://www.coinish.com/calc/) (use expert mode to calculate with estimated difficulty adjustment).
At 0.3 BTC the block eruptor would be barely profitable.

Dear Bitcoiners

we startet that project to bring electronic stuff to you for bitcoins.

we do not scamm!. ive made preparations to show everyone that we are legit.

we took todays charge of the usb asic miners on sale for 29€ only. after that charge they will rise up to regular price again.

much more items will be added to the shop till monday

Bitueuo24

Again, I'll take them all if you agree to using escrow. I will take pictures and post here once the items arrive.

I'll take some as well if you can escrow
