1  Economy / Service Discussion / BTC100 CNY exchange reports 80,000btc 24hr volume on: September 28, 2013, 09:12:16 PM
Either they are lying or something massive just happened:

Can any Chinese speakers check out their site and see what's going on? Do they have a lot of market depth? This is a fairly fast change from 1-2K volume last week.

If they are reporting false volume, it should be obvious to people trading there.

Edit: 99,000
2  Alternate cryptocurrencies / Altcoin Discussion / Litecoin Logo shirt on: August 06, 2013, 05:22:11 PM
Hey, I designed these Bitcoin shirts:;all

I just wanted to see if there is any interest in a Litecoin shirt of a similar design - the Litecoin L in a circle logo.
I'd probably do Black on Grey and Grey on Black.

These are very soft, high quality 100% cotton t-shirts. I like them so much that I basically quit wearing anything else.

If we had enough people interested, I could probably get the price down to 12$ +shipping for a pre-order. Afterwards I'd sell for 15$. (Obviously payments in LTC only!)

Let me know what you think, and tell me what sizes you'd want so I can get an idea of the size distribution.


3  Economy / Speculation / Ticker/charting sites + help request on: March 20, 2013, 09:25:53 PM
Hey guys, I'm aware of the following real-time charting services:

At one point I saw a ticker site very similar to clarkmoody & bitcoinity. However, it was more configurable. It had resizable/minimizable windows inside the browser page for the orders, marketdepth, chart, etc.

I can not find it again for the life of me. Does anyone know what I'm talking about? Thanks.

[Group buy is over. I will sell off the handful of extras I paid for when the order arrives.]
Shirts for sale here:

I see there are several people asking the same question I asked last year...where's a nice & simple T-shirt design with just a bitcoin logo?

I've looked through what's available and I'm not happy with the few remaining options we have. I'm by no means a graphics design or t-shirt guy but what I wanted was very simple, so I have again tried to mock it up. My last attempt just took the common bitcoin logo (used by the older client, many webpages, etc) and put it on a shirt. It turns out printing this is much too expensive, because the image had many colors. As an alternative, I just took the simpler B and put a circle around it.

I'm using a extremely soft shirt - I picked it because I already own one and it's the most comfortable t-shirt I've ever had. I dug around until I found a printer that offered this shirt...however, it's a light-weight shirt, in case you care. (100% cotton.)

If you live in the USA & are interested in one of these shirts please PM me your size and color preference. Let me know if you're willing to buy another color if no one else wants the one you picked. I doubt I will have enough interest to print more than 1 style, but if so, I'll be happy to do so.

Local rules: no trolling. no criticism or negative feedback even if you're supposedly "trying to help." I do not care if you don't like my shirt. I only care if you want one - otherwise, please do not post. Thanks.

PS - these are mock-up images produced by an online shirt editor. They are not photos of an actual shirt. If you think this should be silly to point out, I agree.

Thanks for your interest.

I would like to be able to search for posts of people in a list of "favorite posters."

Perhaps they could even get a highlighted button for "favorites" like the ignore button.
8  Economy / Service Discussion / Bitspend seems broken on: August 16, 2012, 09:25:53 PM asks me to login in order to watch the intro video, help page link broken, signup doesn't seem to work.

What's the deal here? I definitely wouldn't want a merchant to see this.
9  Bitcoin / Bitcoin Discussion / Dwolla bans bitcoin users? on: May 16, 2012, 07:54:38 PM
Surprised I couldn't find a thread on this already (if there is one, feel free to close this one.)

Part of me is glad that they are about to lose a huge chunk of their userbase, because after the fraud they committed against Tradehill (and several other exchanges) it seems like none of us should be using them anyway.

OTOH, I am not surprised a lot of people in the US still use them with MtGox, just because the fees are so low.

10  Economy / Goods / New bitcoin shirts on: March 12, 2012, 02:42:44 PM
I just went looking for bitcoin shirts I could buy with bitcoin. I was kind of disappointed - I went through the entire list of shirt places in the wiki and I didn't see anything I was excited about. Squarewear used to have 1 or 2 designs I was ok with (not thrilled.) But it looks like they've mostly quit selling. A lot of these places want 20$ a shirt, sometimes that doesn't include shipping. With custom shirt design available at a gazillion places, I can't stomach that.

So I found a place that uses my favorite type of t-shirt to print on (extremely soft 100% cotton) and seems to have decent bulk printing costs.

I'm not willing to pay 50$ for 2 shirts just for myself, but if enough people are interested, we can get the price down to under 10$ a shirt, and then I will find the cheapest shipping I can - 5$ would be worst case, because that's flat rate priority. I think 3$ would be a safe bet.

So the deal is - pitch in with me and you get the shirt at cost. 0% markup.

Here's my design on 2 colors. If you are interested, let me know which color you like, (or black) and your size, and we can go from there.

11  Economy / Marketplace / Bitcoinica customer support first impression on: March 01, 2012, 01:50:53 PM
I asked a simple question of the support staff: will I be required to send ID and verify my account if I never plan on withdrawing any USD?
IE - can I be confident that depositing, trading, and withdrawing only using bitcoin will not force me to compromise my anonymity?

I feel like this is a fair and important question.

I got an immediate automated response that I would be getting a real response in a few hours - it's been 4 days, no response.

I've checked the bitcoinica support chatroom several times a day at different times (yes, I realize I'm in a very different timezone.) It's been empty every single time, despite the claim that "we're almost ALWAYS in the chatroom."

I understand this is a small operation, and perhaps answering my question is not a priority. I'm not trying to bash Zhou Tong. In fact, his site/services appear to be very impressive. But I'd like to offer some friendly constructive criticism to Bitcoinica and ALL bitcoin startups: Don't make claims about your customer service response times when you clearly don't have the staff/resources to back them up. This is extremely detrimental to customer confidence, and it's becoming increasingly common.

Just be honest: you're running a one or two man operation out of your bedroom and you probably have a day job and a life outside bitcoin. I think most of your customer base can handle that.
12  Bitcoin / Bitcoin Discussion / It's that time of the year again - your favorite sites are asking for donations on: December 20, 2011, 10:13:24 PM
I'm starting to see donation requests being made by several of the forums I used to be more active on, many of which I have donated to.

From now on I'm only making donations in BTC. I hope everyone will encourage their forums to accept them as well. offers GoDaddy/Amazon/Newegg giftcodes, which happens to be the provider for some of the forums I use - so they don't have to worry about getting exchange accounts, faxing over their birth certificates and life history, etc. They can exchange BTC directly for hosting time and hardware.

If they happen to be using a different hosting provider, maybe get them to send a request to their provider to work with

I don't think this is unreasonable - it's your money they are asking for, and I can't imagine anyone being opposed to cutting out Visa or Paypal fees. Our economy may not be huge, but it's large enough to include ways to meet these guys' needs already, so let's start encouraging that they take advantage of that.

13  Economy / Goods / [wts] Arkham Horror board game, mint condition (closed) on: August 22, 2011, 05:02:05 PM
Played once. I really liked it, but my group doesn't have the attention span. Everything is still in mint condition.

(Not my pic)

Edit: No longer for sale. Thanks

14  Economy / Goods / Wicked Lasers Spyder III Arctic 1W Laser G2 on: August 20, 2011, 08:54:19 PM
Hey guys. Going to ebay this soon, but I thought it would be worth posting here first.

I bought one of these when they first came out:

Mine is in mint condition with less than 5 minutes of use. Has the smart switch and a security key. I haven't used it since I received it (tested it then) because the cheap battery charger broke instantly. (Hundreds of people had this problem.) I ordered a new battery and battery charger last night in order to sell it. Also has the protective glasses.

These are tough to get into the country, as US customs started freezing processing on every one they could find coming into the US last year. They did this by creatively losing paperwork filed by companies they knew were selling these products. This nonsense won't affect anyone buying one from a private citizen inside the US, and it's certainly not illegal to possess (unless you have some local laws against laser pointers.) I'm not shipping internationally.

60BTC shipped. Took me 8 months to receive mine initially. They go for more than this used, because of the problems with customs.
PM if interested.

edit: price updated
15  Bitcoin / Mining support / Have 4+ cards running on one of my rigs...took me months on: July 27, 2011, 08:27:14 PM
First of all, here's my hardware setup for this machine:
MSI 890FXA GD70, 6core, 1000w OCZ
3x XFX 6870
1x MSI 6870

I finally got this running in windows 7 with 4 cards. Before you linux guys jump on me, I tried linuxcoin out, and I had 2 problems. I couldn't underclock 6870 memory, and when I went from 3 to 4 cards, linuxcoin wouldn't start Xwindows.

Windows wouldn't work for a while either. First, with 11.6 drivers, guiminer wouldn't start, Afterburner wouldn't start. I went to 11.7, which was nice, because it allowed remote booting, restarting the miners without monitors (dummy plugs have never worked for me), and the CPU bug was "fixed" - 1% CPU usage on 3 cards. But I could only start 3 at a time. GPUz wouldn't start if 3 cards were mining. 4th card also wouldn't start, no matter which 3 I started first.

I finally fixed this by uninstalling the drivers, deleting the contents of this reg key: 4D36E968-E325-11CE-BFC1-08002BE10318, and reinstalling 11.6. CPU back to 100%, back to monitor cable swapping, but it runs 4 cards.

I noticed overclocking is tricky. You have to switch between Trixx and Phoenix Rising to get the memory down, and use GPUz to check for success. Afterburner still wouldn't run. But GUIminer starts and runs now. Stable for an hour now. Power usage is 730W.

Been a long road...I hope this helps someone. Deleting that reg key was a breakthrough. Before that, going back to 11.6, win 7 wouldn't recognize all 4 cards. Driver sweeper doesn't delete that key.
16  Bitcoin / Mining support / Guiminer + phoenix, hanging on: June 29, 2011, 04:45:40 PM
Several others and myself are having some issues with Phoenix under GUIminer hanging. It looks like it's related to connection problems.

I will come back and see one or two GPU's (out of many more that are still connected and working) stuck at "connecting" and sometimes they will have been stuck for hours. They will start immediately if manually stopped and restarted.

This happens with 1.48 that's included in 6/14 and also 1.50.

Is this a known problem? Any fix?
17  Bitcoin / Mining support / anyone have 4 cards working with Afterburner? on: June 20, 2011, 03:58:48 AM
I'm running 4x 6870's (Win7 x64)- with 3 the system works fine, once I add the 4th card, Afterburner says "failed to initialize display driver wrapper."

I'd just like to know if anyone has successfully gotten this working.
18  Other / CPU/GPU Bitcoin mining hardware / 890FXA-GD70 + 4x 6870 + windows7 64x on: June 13, 2011, 09:03:12 PM
= fail.

Has anyone had luck running a similar setup?

MSI 890FXA-GD70, AMD Phenom II 1090T 6core
4x XFX 6870 using extender cables on cards 2 & 4.

I hooked each card to a monitor, (dummy plug thing wasn't working even with just 2 cards.) First try, I didn't use any crossfire bridges. All 4 displays worked, but Guiminer would not start (just died instantly.) MSI Afterburner showed: "failed to initialize the display driver wrapper" error.

Rebooted with crossfire bridge on card 1+2 and monitors for 1,3,4. (These cards only have 1 Xfire port)
MSI Afterburner gave the same error.

Guiminer would start, but my only temp/fan monitoring tool that would run is GPU Caps, which only shows the temp for "main" GPU. That jumped to 88C after less than a minute so needless to say, I shut down. Not to mention, I was only getting 880Mhash. I have been using this rig with 3x 6870's and getting 865M with 875/325 OC. So all this nonsense was certainly not worth 15Mhash extra.

Any suggestions?
