The only thing I can find are USB block Erupters, which at 1.8BTC/GH isn't a very good deal.
Took a look at the math on some miners such as KnC's Jupiter. $17.5/GH with early October shipping is a 1 month ROI with 150% ROI after a year. BUT if they come LATE October it's a whopping 12 month ROI with just a few weeks of delay.

Exiting my position in the market tomorrow morning around 10 AM EST (if I sell through here). Looking to sell off my final amount, preferably around 0.009 - 0.01 per XPM, depending on market price at the time. If you're interested in not having me drop the price a bit and want to buy in private, PM me and we can arrange something on Skype.

So I recently received 9 miners, the standard hub and fan setup. But apparently I'm mining at 2.87GH/s when it should be at around 3. I see several miners hovering around 266 - 300 MH/s. Does this average out or am I slated to continue mining at this rate?

Would it be okay for many miners to mine to a single wallet file, but only have one computer spend from the wallet?

I know there is a sort of Linux environment for Bitcoin, but I'm trying to run a PrimeCoin miner on some old hardware I have - some without harddrives.
Basically, I need to find a USB bootable Windows compilation/distro that supports networking and that lets me run PrimeCoin-QT. I found BartPE, but that seems to not support networking.

I'm considering throwing together a quick low-volume exchange to convert XPM to BTC/LTC.
I don't plan on making it anything fancy unless it gains traction, but initially what I'm thinking is the following:
- Small one page site.
- Order books for the currencies laid out on display, with prices listed somewhere.
- Fund your site wallet quickly via BTC/LTC/XPM - QR code for phones, etc - 1 confirmation until deposited.
- Automatically fills order, or you can manually choose an order to fill.
Naturally this wouldn't stay this way for long, but it seems with the traction XPM is gaining it's a worthwhile idea.
Thoughts, suggestions? I can have it up within 48 hours most likely. Any other sites already add XPM?

Where can I buy the standard setup I've been seeing with the whole Erupter lineup and a fan at the back?
In BTC, if possible.

As the title states, I've got PHP and general web development experience. I'm looking to lend a hand or start a BTC related web development project for you. I accept Bitcoin or GPUs (LF a 5870 specifically, if possible).

I'm starting work on a relatively simple payment processor for use on TOR. The concept is simple - you want to accept payments over the deep web for items and a ten second solution without any fees or hassles. OnionPay is meant to do that.
You visit the site. With one click, you generate your public payment address and your private key/password to log in for the future. Select some options, such as redirecting to your site upon payment completion. You hand out the public payment address or integrate it into your site.
When someone needs to pay, they see a unique address to send coins to. The coins then get sent your personal wallet. After they pay, they're redirected to your site where you can use the API to verify some information about the payment - or, if it's for a digital purchase, they can immediately receive the information or download the product.
Generate your payment address. Hand it out. Get paid.

I'm trying to find a way to generate a private key and public address using only PHP without either GMP or BCMATH. Can it be done at all? The reason for this is I am limited to a hosting provider on the tor network with neither of these.
What are my options?

http://198.12.67.18/testA few days ago someone got into my server, got my SQL credentials (located @ config.php), and modified some files and other shenanigans using the login form above. I'm unsure how it was done and I'd like to know if someone could hack it again. I'm not offering much - 0.05BTC - but the coins are yours for repeating what he did and letting me know how it was done. It only took them a couple minutes, and the form there should be enough. The exploit uses login.php.

As I'm sure others are doing, I'm trying to get money into OKPay from my Mt. Gox account. I've been told transfers take from minutes to days depending on when Mt. Gox has money in OKPay. BTC-e has a counter on their site that tells us how much money they have and where. Is there a way to get this information for Mt. Gox, or do we know when they "refill" their reserves?

I plan on vanity mining addresses soon, and I'm looking to purchase a single GPU that will give me the most MKeys/s. I'm currently aiming to get the HD 5870.
I've looked around and it seems that the HD 5870 gives up to 30 MKeys/s.
There is only one big informative thread and it seems that someone overclocked/configured a 7xxx card to get 50 MKeys/s, but no direct mention of which card in the post or what the settings were (can't find the post at the moment).
Then there's a claim that the HD 5970 can get ~40MKeys/s, but it's a single post with no other sources/statements.
Has anyone thoroughly researched vanity mining to see which card would hash the fastest?

This is a project I just recently started. It's written in PHP, upload the script somewhere and run it through your browser. It shows when there is arbitrage available within the BTC-e exchange itself. It does nothing else yet, I'm still working on getting automatic trades executed. Fees are automatically calculated. If I've missed something here as far as the actual calculations go please let me know. Yes, I'm aware it's only going off last price at the moment, it's going to be able to calculate using the whole order book soon. It's sloppy and quite awful, but I've only just started. I've had good luck with it during the night when prices tend to jump around a bit more, and conversions through RUR/EUR seem to yield the best results. <?php

Is there some sort of alert service for MtGox that would notify via Email if the price on MtGox broke it's current daily low/high? I'm sure I could do something like this easily myself in PHP but has a service like this already been established?
Thanks.
