Just curious if there's any good way to sell Casascius coins these days. I've seen a few sold at auction houses. A few years back there used to be a website for someone acting as a broker/cosigner, but I don't remember what the website was called and can't seem to find it anymore. Seems there's at least one loaded one listed on eBay right now, but I know they're generally cancelled on that platform. Any other ideas?

I've got a ton of Bitcoin "firstbits" addresses that were generated (and written to the blockchain via transactions) back in the day... 2011-ish. Is there any interest in those? Thought there might be some interest as a sort of novelty to have, a digital collectible.
They've been kept on air-gapped storage, never seen network or internet access, and would remain that way (securely deleted as sold). I generated them and have been the sole owner of them this whole time - no one else has touched them.
Some random examples include:
1MunCh - 1MunCh1kFAwisrTySvZvyxsXkrEeFCMehH
1BLing - 1BLingJstkxW53nsjNbDe7zFUJ5P42KuJC
1DiRty - 1DiRty8t4qJhCmp5QL2BqThdHLcAgHTDeb
1MaRTiN - 1MaRTiNSNqawwV3iGCakD2AA4Jj8m9TQvL

EDIT: PROJECT CURRENTLY IN PROGRESS 9/8/14.I cannot count the number of times that firstbits would have been useful to me personally, and I imagine to many others as well, so I would like to get serious about revitalizing the firstbits website. I'd like it to be open source as well, so anyone can help improve the code or host a copy down the road. The code should replicate the behavior as listed here: http://firstbits.net/about.phpBasic logic should be as follows: 1) Gather all Bitcoin addresses from a block. 2) Compare first two characters of first address in the block to firstbits table. 3) If a match is found in the table, add another character of the address and repeat. 4) Once it is not found, add temporary firstbits into an array and move on to the next address. 5) At the end of the block, compare all temporary firstbits found from addresses in the block to each other. Resolve any conflicts by adding characters to conflicting addresses. 6) Add completed list of firstbits to firstbits table. Other requirements: - Must store data in a MySQL database - Must use either PHP or python (or both) - Must be able to connect to a bitcoin daemon (bitcoinQT) to gather the addresses - Must be able to compute and store firstbits with additional length (i.e. 1sgtspike and 1sgtspike5 must both return 1SgTspiKe5HHkjdSeD72q9WsiJhRiaxf9) - Must be publicly hosted to github upon completion Bounty: $200 of BTC. Now I realize the bounty is low for a job of this complexity, so if someone else wants to help chip in a bit more to the bounty, please do so! It would be greatly appreciated. Any questions? Any volunteers who wish to code this?

I've been running a full node since 2011, updating it as needed to the latest version. Recently, it stopped syncing beyond about 4 weeks ago. I decided to upgrade to the latest version, 0.91, so I uninstalled the old one and deleted all the blockchain data (everything in the blocks directory). Downloaded the 64-bit version, and launched it, only to receive this error:  It creates a blk00000.dat file and an index directory within the blocks folder during this attempt. If I launch it again, then I get this error:  If I delete everything in the blocks folder again, I get the first error again. What have I done wrong, and how can I fix it? |

How can I automatically add all Bitcoin addresses ever used to a MySQL database in realtime?
I need to move firstbits.net away from using blockchain.info's API, since the firstbits no longer appear to be working at blockchain.info and haven't been for some time. I'm no expert programmer, but I know enough about PHP and MySQL querying to get the website job done. My problem comes in getting the data from bitcoin-qt (or another source) in the first place.
I'd like to set up some sort of cron job that looks for new addresses in the latest blocks coming through, and adds said addresses to the MySQL DB after 6 confirmations. What's the best way to accomplish this?

We should switch to uBTC and be done with it (forever). Switch our clients, our exchanges, our store plugins, etc, to use uBTC by default. - It would give Bitcoin two remaining decimal places, which is what people are already familiar with, and would be much more compatible with existing financial software.
- One uBTC is worth enough that it wouldn't be too cumbersome at this point to use. Buying something for $25 would be sending 31,255 uBTC.
- The conversion is easy too - just remember 1 million. You multiply or divide by one million to convert between current BTC and uBTC.
- We would only have to switch main denominations once, whereas a change to mBTC only helps us with the current price. If the value of BTC continues to go up, we'll find ourselves in the same situation of having a main denomination that is too valuable.
- Finally, it would give enough room for BTC to grow however large and valuable it could possibly grow. Even if everyone in the world used bitcoin, uBTC + 2 decimal places would be enough to provide all the precision we would need.
Who is with me, and what are the steps we need to take to make this happen? |

Many people say that the difficulty follows the price, and not the other way around. While this is largely true, it is also true that an increase in the difficulty will help drive the price up. Let me explain.
If I am someone who believes in Bitcoin long-term, I want to invest. But investing doesn't have to be just buying Bitcoin directly - it can also be buying miners that produce Bitcoin. A rational investor will look at both options:
1) Should I buy Bitcoin directly OR
2) Should I buy a Bitcoin miner that can turn my USD today into even more BTC down the line than what that USD would buy me today?
All the way from when BFL announced their ASIC products up through July-ish 2013, mining looked to be a potentially better option than simply buying BTC directly. It looked as though an investor could potentially receive more BTC through mining than they could through buying BTC outright. But now? Now, mining is a pretty terrible investment (though it gets better with the price increase). Investors looking to acquire BTC will simply buy BTC outright instead of buying mining machines for it. And that will drive the price up, whereas buying miners will not.
Conversely, if the price goes up significantly without a corresponding increase in difficulty, mining will again look like an attractive option to invest in.
In this way, difficulty and price are most assuredly linked both ways, and keep each other in check.

I'd like to buy a Windows 7 or 8 unused product key, 64-bit, with the disc ISO (link to where I can download the ISO that will work with the code you give me). Edition doesn't really matter so long as it's Home Premium or better. Willing to consider all reasonable offers, but I do want to know your source for the product key, and will consider the price accordingly.

I'd like to downsize my mining operations a bit, and am selling one 60GH/s BFL SC Single for 70 BTC. I've had it for about 3 weeks, and it's been mining perfectly. I've been using a computer PSU, as a BFL PSU was not included. PSU is not included in the 70 BTC price, but I can provide one to you if necessary - just PM me to work out the details. Included shipping will be via Priority Mail.

I found http://www.miningmonitor.com/, but they don't monitor BitMinter. Is there ANY service that will at least send an email my way if my miners are down at BitMinter? Those of you mining at BitMinter - what do you do? |

Blockchain.info's firstbits lookups are not working. 1sgtspike doesn't come up. 1a comes up, but with the wrong address - it should come up with the address from block #1.
