Man darf neuerdings Dienstleistungen auf ebay verkaufen?!  Vom Preis mal ganz abgesehen hat das Ding doch viel zu viele Risiken als Käufer - du garantierst ja nur auf einem Pool zu minen, was wenn der eingeht oder gehackt wird? |

Another idea of mine, that might give relatively small but relatively well secured payouts: Lending BTC on Bitfinex. Bitfinex is an option platform offering amongst other things to open an account and lend out BTC or USD deposits to its users who want to do leveraged trades. Even though the interest is usually lower than what traders can/do(?) earn, the interest is guaranteed and secured. I'd like to offer to open a fund in BTC which get deposited to Bitfinex and pay out interest to its members periodically (interest on Bitfinex is credited daily). Current numbers from lending out BTC show quite jumpy returns (in 14 days I had 1 day with 0 interest and 2 days with more than 10% APR - averaged over that timeframe I'm at ~3% APR) which are of course higher if the USD price falls (or trader think it might fall), as people borrow BTC to sell them and buy more later at cheaper prices. As interest compounding is actually quite a nice feature of Bitfinex (since it is paid daily, I already have ~0.1% more funds to lend out and I gain interest on these as well already) I'd probably look for people who don't want daily dividends or something like this - it would anyways only create bitdust. Maybe a payment once a certain treshhold in interest has been reached? Also withdrawals are not immediate at all, on one hand you can of course only withdraw coins that are not currently actively lent (d'oh!) and also Bitfinex has all coins in offline storage and processes withdrawals on business days, so it might take a while (= up to a few days if you request a withdrawal on friday before easter for example) until a request is processed. This fund should be viewed as long term investment, not for day trading. Potential risks mainly include Bitfinex going bankrupt (unlikely due to trading activity as they get a cut on every trade, unlikely as well due to being hacked as BTC are supposedly stored offline), MtGox going out of business suddenly and taking Bitfinex' money with them (which would not be Bitfinex' fault but still I guess they have quite some funds over there to execute the user's trades) and me scamming you willingly (  ) or unwillingly (e.g. I die + destroy my phone with the GAuth key in the process and don't have a dead man's switch in place). Your benefit over lending directly at Bitfinex is that you don't need to set up and secure an account over there, as you can participate in the whole thingie here just by submitting BTC and an address that will be used as payout address, your "alias" in reports and to sign any payout requests. Also you get nice stats/graphs done by me. My benefit from all this would be that I gain a part of the interest generated (5% seems like a reasonable amount) and that I didn't create all my nice statistics and graphs just for myself. If you are generally or especially interested in something like this or have found a major flaw in my idea, please feel free to let me know in this thread!  tl;dr: Interested on earning a few meager % on a relatively conservative investment? Express your interest in this thread! |

Probably by then you need to send in some DNA samples, a video of your most recent colonoscopy, an iris scan and finger prints, all with a 2 ounce 24 karat seal of approval from the POTUS to some "lawyer" on the cayman islands... to get back your gigamining share claim on GLBSE.  |

How trustworthy are which numbers in the UI?
The ones in "Account overview" are currently rounded (up + down) to 2 decimals, in "History" --> "BTC" the numbers are always displayed with only 4 decimals, the only place where I've seen all 8 decimals exposed was in the "Withdraw" section. My borrowed funds + open offers however don't add up to exactly the amount there, only very close to it.
Is an interest payment that shows up in my history as e.g. 0.0167 BTC in reality somewhere in the interval [0.01665, 0.01674999] or is it really exactly 0.0167 BTC? If it is the first case, please display all decimals, as after some time numbers might not add up any more...

As far as I understood it, the forks were not very far apart (~60% of hashing power on the 0.8 fork) so probably Gavin's alert was published to the net before this could take effect. Anyways, I guess someone else who actually was online/awake at that time can say more to this.  |

Firefox 19.0.2 on Windows 7 x64 Ultimate, so far I only experienced this on Bitfinex. Chrome works as expected, maybe it's an edge case for Firefox or some weird HTML/CSS/JS on the page...?

One of my ideas is to do something like a http://en.wikipedia.org/wiki/Parimutuel_betting of options (similar to the "binary options" thread here). You could simulate these. On one hand with parimutel betting the house never can loose, on the other hand however when betting you don't know how much you'll earn. Also the earlier you bet (especially on something like BTC prices) the worse, as you cannot observe the market, other bets and their predictions as well as having less money for a longer time. As you only deal with "play money" you could offer parimutel options, but keep the wagers secret until the deadline has passed. |

Well, you could make it virtual, as in a huge order causes slippage but the price resets on the next time you get an update from Gox. On the other hand that would only lead to people dumping a million of single Bitcents instead of 10k BTC at once...  |

Are trades executed against existing offers or just against the latest trade price? Meaning: Is there slippage?

It was important to resolve this before either chain was more than 100 blocks past the fork as then those coins would be spendable which would have been "chaotic".
Why? After 120 blocks, what makes those coins different from any other unspent output? The limit to spend newly mined coins is actually 100 blocks (120 in the UI) and since they are coming "out of thin air" they would be viewed as nonexistant as in "never been there" in a different chain. |

Auto-Lend does not seem to play along too nicely if you from time to time also want to fill specific loan demands. I had Auto-Lend active (at 120 days VIR), then saw a loan demand I wanted to fill, tried to do it with Auto-Lend active (didn't work, as I had already an open lending offer for my unlent balance), then deactivated Auto-Lend, filled the offer and reactivated it again (same settings as before). It took a few minutes until it posted the remaining BTC in the account as offers again... My preferred way of Auto-Lend behaviour would be to have it reduce (or cancel + repost, but that would cause me to loose my spot in the VIR queue) open offers if I take a concious decision to fill a loan demand, so it kinda stays in "cruise control" mode but still allows me to snatch some opportunities. Also something weird I recently experience on the page: Usually I middle-click links to open them in a new tab (using the current Firefox stable). Since a few days this does not work on Bitfinex any more (Ctrl+Left clicking also doesn't work ) and I have to resort to Right clicking + "open in new tab"... |

It's not a hard rule (in the sense of "a client that does this will create an invalid fork") that the newer transaction HAS to be ignored, no matter what, but currently this is the case.

@Sukrim One then only would need the chain headers (a handful MB), the set of unspent transaction outputs (currently ~170 MB afaik) and all full blocks since the last set was created to update this set to the most current state. Once a new set gets released, you verify its integrity and after a few blocks discard the old set and the content of the blocks leading up to the new set.
Hm what "set of full blocks" do you mean there? Just maybe the last 1000 full blocks. And if a client gets started and there are 300 new blocks, the old 300 get discarded and the new 300 gets downloard? And can you tell me something about the enforcing. Who finanlizes? Is it just a matter of the developers of the competing client softwares? So for example I could come up with my own software that will do the things, like you (and others) suggested? With "set" I mean a data structure that contains all unspent outputs at a certain block height (e.g. 250000). Every full block after this one (250001, 250002...) contains new transactions that use these unspent outputs as inputs and create new ones. Once you have a trustworthy chain of headers (a few MB), you can verify that the latest blocks are also valid ones (correct difficulty). To verify all block contents and transactions, you also need the block "body" and all current unspent transaction outputs. If you only see a valid header this does not mean that every transaction contained in the block is ok. If you have a "light" (SPV) client, it will only look at the headers and request from nodes who store all the blocks information also some data about addresses you're interested in. You cannot discard blocks at will, if you want to be able to verify transactions on the network if you haven't got a set of all unspent outputs at a certain block. Having a header chain, a set of unconfirmed transactions and full blocks since that set means you can verify any transaction on the net and also mine - but you cannot see any transactions in the past any more. This would be somehow a middle state between a "full" or "archive" node (which stores all full blocks) and a "lite" node (which only stores headers and requests verifiable data via bloom filters from nodes who store all transactions). |

Windows is not the default OS. It's just, unfortunately the market leader, or the OS with the largest share of users. I'm sure that if I can't dual-boot, I can probably do a Live CD.
Good luck with catching up on the blockchain then... depending on your needs, you're faster to just run the stuff you need on armory-python. Anyways, doing a closure run brings my poor little nettop to its knees (even with the "smaller" hash maps) - at least after a few hours it didn't show any kind of progress, so I killed the program. 1GB RAM is not cutting it at all apparently. |

Also were these the first 3 days where oyu did download the whole chain etc. or does your node really use 15 GB of traffic every 3 days?  |

Protipp: Use a BIP32 deterministic wallet to create addresses on the fly on the server but keep the private keys offline in your wallet.

Ein bisschen Feedback (was gefällt, was geht gar nicht) zu bisherigen Vorschlägen wäre toll, damit man nicht nur so in's Blaue rät.
