How do i get my friends to mine for me without them having to use my user.  Of course i give them worker user and pass.

K.

Worker user and pass are all you should need, could you please clarify?

Please be careful everyone.

I keep trying to add them to the chart, but as I look around all of their details seem strange.

Why is the first price always mentioned the $18/GH?  The actual machine cost always looks like it was added as an afterthought.
The listed power consumption says .7W/GH.  Wouldn't that be 1428 MH/W?  That would be over 1400% higher than the others in the market.  Again, difficult to find the actual spec here.
There was a warranty situation that was completely incredible.  They say that since then lawyers have gotten involved and told them this was unreasonable.  Now no protection is given to consumer.
They are taking money for preorders.
August is very soon to be putting out a miner that is so fast, cheap, and power saving.  Everything seems too good to be true.  They did have someone come in and say they've been working on it for a year already, though.


You need to understand, that MetaBank can fool me. In this case, I do not guarantee a refund. This exchanger there for about a year but I do not know anything about his honesty. They refused to make the contract, and said that it is at your own risk. But they provide a guarantee if I buy them Bitcoins, they kept me (bitcoins on my local machine). But I do not have a right to spend it. When they make the device, I'll have to send that amount Bitcoin them, in which case they will be given a device to me. It will have no effect on the court in the case of fraud. Because there is no contract with them. Russian court recognizes only the written paper contract. I can not sue the claim unit or refund at MetaBank, if they will take back my deposit but will not give me the device.

Sincerely, NaimaOnline

kncminer has like 30%+ VAT/import/etc fees onto of their listed price.

Hi thanks for the input.  I decided recently to not add taxes or shipping to the totals, because that can so greatly change the price in some cases that there is almost no way to put the statistics accurately.
504  Bitcoin / Hardware / Re: Low Watt Miners -GH/BTC -ROI with difficulty [Updated June 1] on: June 02, 2013, 03:30:05 PM
There is a formula to calculate a network hashrate out of difficulty (https://en.bitcoin.it/wiki/Difficulty):
hashrate = 2^32/600*difficulty
But is there a way to calculate coins per day with hashrate?  None of the equations that I've found work out.  People argue, and it makes sense, that you should be able to take the total coins minted per day by everyone, compare that with the total network hashrate and your hashrate. 

your coins per day = (your hashrate / total hashrate) * total coins per day
There are many other methods I've tried, but nothing comes out even close.


Or you can try to 'predict' hashrate growth with some formula. I used future value, fv(). It's very crude formula, assumes the same, constant, increase in every step. And we know that the network doesn't behave that way - with the arrival of every new technology (first GPU, then FPGA, now ASIC), network expanded rapidly. First two times (GPU and FPGA) that growth slowed down and leveled out quickly (http://bitcoin.sipa.be/, look for exponential charts).

I was thinking of making a chart based on the release dates quoted by all the companies, and the other detective work that has been going on, then add some normal growth pattern of the network hashrate to see what is likely to happen in the next year or two.  I'm sure we could compare an even growth formula to help model the statistics.
At the moment I'm basically using that pattern on my spreadsheet..  would be nice to have something a little more realistic.  The growth could be 13%, but end up looking like 20% if a lot of the growth is weighted toward the beginning of the time period..  like you say happened with GPU and FPGA.

nice work btw, FCTaiChi  Smiley

Indeed and I agree with your Bitfury stance in the other thread Wink
Thanks!

I'm not saying you're wrong, just would like to know where the disconnect is.
We can be both right.
Just that you're calculating difficulty increase, and I total network speed. It's easier for me to think that way.
Oh interesting, if you come back to the thread I'd like to talk about that.  I can't figure out how to make any of the network hashrate equations work.  They're coming out extremely low, but I'm just starting to mess with it, probably a multiplier I'm missing.
506  Bitcoin / Hardware / Re: Low Watt Miners -GH/BTC -ROI with difficulty [Updated June 1] on: June 01, 2013, 04:12:34 PM
Difficulty changes every 2016 blocks. How many days it is depends on the total network growth.

Another thing, if we take 13% diff increase (every 2016 blocks), that gives around 2000 2600 Thash total network speed in a year (using future value formula in gnumerics fv(13%,26,0, -110)). Who will contribute that growth? BFL Wink
Really?  The projection I'm using shows difficulty 13% at:
537,192,522
around June 6 next year.

Same time period with 18% difficulty gives:
2.06E+09
2,056,082,027.04


I'm not saying you're wrong, just would like to know where the disconnect is.

I can't add this manufacturer until some of these questions are answered.  Even then the preorder status set to GOGOGO makes me question them.  If you are the go between naima53, I would appreciate it..  otherwise I will try some google translator in a couple days Smiley
508  Bitcoin / Hardware / Re: Updated difficulty on 25th on: June 01, 2013, 02:48:56 PM
I want to say, I dont get it.

I have taken a look at the calcs and have still not gotten how you get to the numbers.

Do you mean an average increase of difficulty every 14 days with the %? Or per month? Per year?

Did you look at sheet #2 on the spreadsheet?  It would be very confusing if you don't see that there is more than one.
Difficulty has been increasing about once every 12.1 days lately.  The percentage is gotten from taking a whole year of those and averaging them.  So each column represents a different average difficulty.

If anyone can think of a way to make this easily readable I'd be grateful.  I'm starting to think, though, that it's just a complex set of data that takes some time to understand, for the uninitiated.

I'm not complaining either, just also scratching my head too (I think a bit more hair came out when I did)

It all seems a little odd, and confusing to a noob like me.

No, I hear what you're saying, the rebellion is on.  Lets all go solo mine!  Smiley

513  Bitcoin / Bitcoin Discussion / Re: Bitcoin as a catalyst for Health Care (Worldwide) on: June 01, 2013, 12:38:51 AM
I think the ability to do micro payments could help.
I'm not sure what is coming in the future for medicine, I'm sure many of the things mentioned in this thread are on the way, and sooner than we would expect. 
At the moment though I believe the most undervalued medicine is preventive.  There are cultures that have explored this aspect for thousands of years, finding ways to make the practitioner more resilient to stress and disease.
Not only will micro payments be helpful to find the proper fit for a teacher or method. (from DIY to one on one classes)  Doctors, specialists, nurse practitioners could also do short online interviews.  This could be helpful to find the right person, and allow people who want more control over their services to not feel like they are restricted by an insurance company or whatever random recommendations they are able to get. 
Of course in this situation a micro payment might be .2 - .05 BTC but in comparison to the normal overhead you have to pay for just by walking in a door this is nothing.
514  Bitcoin / Hardware / Re: FPGA - profitability vs effeciency? on: May 31, 2013, 09:24:21 PM
The 5 columns on the far right represent average difficulty through the year from 8%-28%
515  Bitcoin / Hardware / Re: Low Watt Miners -GH/BTC -ROI with difficulty [Updated May 31] on: May 31, 2013, 07:21:51 PM
You should re-think this area as it is very confusing or at least give a better description. What does a 'negative' number mean. Also what exactly do those percentages represent, what hash rate?

Update the OP to, don't just reply here.

I update the OP every day.
Can you think of a way to state it more clearly?  People don't seem to understand what ROI means, I tried to use that for a while.

Did you read above that section where it says, "BTC mined in one year minus power and cost"?
The section below says, "The columns to the right are an estimate of how many BTC you will mine in 1 year minus cost of machine and avg power costs."

I'm not sure what else to do here.

if I read the table correctly, for all those shipping ones, nothing is profitable for a year!

A wash at best it looks like.  *crosses fingers* for avalon chips
516  Other / Meta / Re: Marketplace trust on: May 31, 2013, 03:35:18 PM
Good point tysat.  I think his problem with this is that the column is named 'BTC risked'  Whereas this could imply risking your reputation, currency or anything else. 
I'm not sure what it could be, but there may be a very simple solution to this with a slight change in the column's name.  'Value in BTC risked'  'BTC value of transaction'

It's perfectly easy to understand once you know what the column means, but at first glance it can be a bit confusing.
517  Bitcoin / Hardware / Re: FPGA - profitability vs effeciency? on: May 31, 2013, 03:21:59 PM
I have all this laid out if anyone hasn't seen: https://bitcointalk.org/index.php?topic=209750.0

Now of course this changes if you are preordered already, or the times change again...  There isn't really anything you can buy at the moment (until the avalon chip order comes in) that will be a better investment than just buying btc.

This list might be easier.
https://bitcointalk.org/index.php?topic=209750

The problem like they said is that you're not going to get your machine right away.  For those who have their ASICs right now...  yeah...
519  Bitcoin / Mining speculation / Re: predicting difficulty on: May 31, 2013, 01:20:13 PM
It's not really work or art, are you sure it's not a game?  I suppose this does effect our livelihood, maybe it is work.

This is past data for mining difficulty:

Date          % Increase   Difficulty

23-Jan-13    8.64%    2,968,775
08-Jan-13     8.64%    3,249,550
05-Feb-13    10.33%     3,275,465
18-Feb-13    11.47%    3,651,012
01-Mar-13     19.63%    4,367,876
14-Mar-13    10.98%    4,847,647
24-Mar-13    38.13%    6,695,826
05-Apr-13    14.59%    7,673,000
30-Apr-13     12.28%    10,076,293
14-May-13    11.03%   11,187,257


My list shows different percentages for some of those dates..
For instance 1-23-13 is -8.64 and 1-8 is 9.06%.  Oh and you're missing 4/17

What's a conspiracy?  Oooh conspiracy theory.  That means something is silly.  No..  it means that two or more people came to a deal that is somehow detrimental to a third party.  That doesn't mean 'THEY'RE OUT TO GET YOU!'  It does mean that they're out to get whatever they can.  If you don't think 'scary conspiracies' happen then you need to pay more attention.
Do you even know what the LIBOR scandal is??
Ha, I'm responding to thin air, you didn't come to learn anything, but to cast aspersions.
