Found sale on usb block eruptors 39euros per

[Trading]

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.

[dwma]

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

[stanleym]

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

you guys asked for prof .

[PEBKAC]

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 -.-



stanley

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.

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

No

This, No.

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

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.

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

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.

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

[uski]

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

[NWO]

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.

[LordTheron]

@ 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.

[FiNaLize]

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?

[LordTheron]

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!!!

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.

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

[monbux]

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.

[Trading]

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.

its legit!

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.
