About the new wallet format and Trezor: What stick said is true, you can make multiple accounts inside one wallet (a different bip32 derivation path is used, for example account one is 44'0'0', account 2 is 44'0'1').
In addition a trezor can be made to hold any number of wallets by using different passphrases. The passphrase is simply added to the seed, that way you get a completely separate wallet for every distinct passphrase.
In more advanced setup, you can have multiple passphrases each giving you completely separate account address space with plausible deniability. http://www.reddit.com/r/Bitcoin/comments/2dqksb/electrum_trezor_one_happy_me/cjs5dd8That's a really neat way. As I understand it, I have one seed (BIP0039 mnemonic seed), and have several branches as an individual wallet each. And/or one seed with different passwords, which lead to different wallets. Well, anyway, I need to secure one seed and some passwords :-) Is it planned to have such a setup in the new wallet format? Any news on Trezor integration? As all of this looks now, I think I will scrap my raspberry-offline-armory-secureconnection project. All of what I planned would be possible with one online Armory, WO-wallets and a Trezor. What do you guys think about the future of "real" offline Armorys? Any use any more, except for multisig/lockboxes? Ente |

My "Tradable Balance" is good. Still, I can't borrow money. It says "Invalid offer: not enough margin balance" with all amounts.
Anyone else has this problem?
This is serious, I can't work that way!
Please, fix this ASAP!

From: tubro The non-profit I was talking about is rockzipfel: http://www.rockzipfel-leipzig.de/ . It's definitely non-religious and non-political. The idea is rather unique: They make it possible for parents to stay close to their small children while working and foster community at the same time. You go there and find everything you need in an office and your kids get looked after by volunteers from all over the world. I have been going there with my little daughter for about half a year now. In fact I am working there now They have been featured in quite a lot of national media and won family friendlyness prizes and EU funding. They are a tax-deductible common-good non-profit in Germany and $1000 would make quite an impact there. Do you think they would be eligible? I have spoken to them yesterday and they would be open to accepting bitcoin. Hope to hear from you soon, Stefan They seem to be a legit non profit organization and are mentioned in a big magazine. The workers there work for free though there is a monthly fee for it. The magazine writes its still way cheaper than a kindergarten or a childminder. I think its true that they dont earn money and the fee most probably is only for covering costs like rent of the flat, internet and so on. Heh, that's funny, I am at Rockzipfel regularly! :-) I can confirm all points: they are an NGO, registered and tax-deductible, apolitical and non-religious, and generally a really great project with nice people. In fact, now I feel stupid for not having that idea myself, to ask them to accept Bitcoin! :-) So, yes, let's give them some love! Ente |

Article says public master key and public child key?? Thats guaranteed to happen and think it's safe.
The public "keys" aka addresses obviously can be published :-) When publishing the public master key, people can calculate the whole chain of public addresses. This will of course remove all anonymity. Still, this is (as I understand it) the proposal of those "hidden addresses" or how they were called. You publish your public seed, and customers generate their own individual payment address with the seed and a random nonce. Ente |

Anyway, the BIP32 spec explains all this.
Yes. But all that cryptomagic is so far out of "normal world expectations" that most people won't consider this. And I can't blame them. All wallets should bump a fat red flashing warning explaining this in few words whenever a master key or a private key is displayed, exported, backupped or printed. Well, once at least. I will simply not export or communicate *anything* from my wallet except public addresses. OT about BIP0032 seeds, which Armory will soon support: I wish to make a brain-seed. Like a brainwallet-address, but creating a seed instead. Would there be a standard for that, or at least an expected method (like sha(passphrase) for a single private key)? People, be very careful when doing this and read your stuff. Many had and many will lose all their funds with this. Ente |

Are swaps the lending portion of bitfinex? OP says the three main wallets are exchange, margin trading, and lending. Yet I find no "lending" area.
You can define somewhere (when signing up?) what type of user you are. Depending on this, you might not see all three types of wallets. A sure sign is on the top right corner, that box shows all wallet types and their funds. Micro flash crash: (come on, a 10% difference to other exchanges is nothing more than a micro one) Interesting, I didn't think of that one. For some time I only follow the BitFinex charts, so until now I was under the impression "today, exchange rate fell from $550 to $450". No, it was only on BitFinex, because long position liquidations created a mini avalanche. So I better start watching some other exchange rates too, when it gets wild. I'm relieved we didn't break the $500 support globally, then. Also, +1 on slowing/halting liquidations when the exchange rate drops too far below all other exchanges' rates. I guess the associated risk is small enough and the gain for the users and platform makes it worthwile. Ente |

Hats off to Bitfinex team and Congratulations for perfect handling of the margin call liquidations !!! This was really something, I watched it all in real time.
To everybody else, it is now official, we have some 30 million worth of morons among users, who were holding onto their losing long positions till the very end. I am trully sorry about your losses, but you did knew perfectly well, all along, about what could happen to your positions, and it did happened.
Quite a harsh statement. But please, enlighten me, how exactly did it unfold on bitfinex? Ente |

Great to see Bitfinex now sending emails out regularly when changes are announced!
Josh, is that your work? :-)
About the changes: that 30%/15% numbers, does that mean "I need 30% in real value to back up a position" (pretty clear) and "I can't enlarge my position when I have less than 15% margin (and will eventually be liquidated when that number falls even more)? Or am I all off?
Thank you guys,
Ente

Hi,
Yes I am working on packaging Armory. I actually have 0.92.1 packaged, but I am going to wait for the next version to be released and package that due the privacy issues that came to light recently.
I hope to get Armory into testing in time for the Jessie freeze. Then I will also look into getting Armory into wheezy backports.
Let me know if you have any questions.
Feel free to also email me at joseph.bisch [AT] gmail.com.
Welcome to Bitcointalk! ..and thank you, again, for the work you do! It's much appreciated here! Cheers, Ente |

Can someone explain the logic of underbidding swap demands?  i.e. placing your swap demand at 0.0999 or one penny bellow that at 0.0998. It's as if you're artificially keeping the demand high while don't really want your demand to be filled  It makes sense for offers where they're underbidding each other, but if anything i'd expect demands to up each other by a penny and placing demands at 1.0001 Prolly people who don't fully understand what they are doing! I find it very hard to believe that somone who puts a $100k figure swap ask at 0.0999 doesn't know what he's doing or a $350k swap ask just under that @ .099 ..maybe they didn't put that 0.0999 after a 0.1 offer was there, but before? And in fact the 0.1 guy overbid the 0.0999 one? 0.09990 14 318.04 19:35:38 10-08-2014
0.09989 100 000.00 20:27:42 10-08-2014 There's at least one who didn't think it hrough, though ;-) Ente |

I've had to export cold storage keys
In BIP0032 compatible wallets (which Armory is not, yet), any single private key plus the non-secret "master address key" (or the like) leads to all private keys being calculateable. Not sure how "public" that aster key really is, in the real world. Nor do I know if it's the same principle in Armorys current wallet format. I would consider the whole wallet to be compromised when a single private key leaks. Edit: There's this article to HD wallets: http://bitcoinmagazine.com/8396/deterministic-wallets-advantages-flaw/Ente |

Is there any way to have a custom vanity address be the start of a new deterministic Armory wallet address?
What do you mean by "be the start"? Like, the seed (many random words) in BIP0032 compatible wallets, like Electrum? Or the first Bitcopin address in that wallet? Like having a vanity address in the wallet without importing it? Or the "public chain seed" (or how it's called), which is normally completely invisible? Edit: Nice article: http://bitcoinmagazine.com/8396/deterministic-wallets-advantages-flaw/Ente |

Updates? Also, since MS quit on XP, does that mean you (or Goat Pig) will stop making it work for XP?
(Believe it or not, I still use XP today.)
XP? *shudders* :-P Compressed keys will be supported with the new (BIP0032 compatible) wallet format. That is one of the next bigger projects, so it'll be here eventually. As I understand it. Ente |

http://www.reddit.com/r/BitcoinMarkets/comments/2cruxj/this_bitfinex_credit_bubble_cannot_end_well/cjiue2rIf it is in fact true that.. "The flash crash was a prime example of that. But, when one exchange has a price of $100 and another has a price of $530, it is safe to say that is an arbitrage opportunity, and what we learned from that event was to try to unwind positions in a more complicated but more orderly way. We never enter into positions ourselves, but there are a lot of bots that run on our exchange and others. " then why would "we" as in Bitfinex need "In regards to flash crash issues, we strive to make sure that our prices are not becoming drastically uncorrelated to the overall market for bitcoin. The algorithms we use and the trading strategies are part of our hard won experience after riding through extreme events like those you mentioned, and I can't disclose the details, but we learned some valuable lessons, and I don't believe an event like that can happen again, or at least, we have taken steps to try and protect people from that specific situation. " In his post Josh Rossi writes: "First of all, no lender at Bitfinex has ever lost money. Ever. " Is that true though? I have read multiple times that lenders lost money (about a 10 % cut) when Bitcoin crashed from 260 to 70 in April? Can anyone of the veterans here confirm? Bitfinex covered 500,000 USD in lenders losses. Noone lost coins/fiat in that event lending. Yes, that's what I remember too: no lender lost money. Some traders complained about the rollback, naturally: those who "lost" their $70 (or similar) Bitcoins, and complained that they would have "lost" money there. Of course even they would have been wiped out in the next minutes, when the uncontrolled meltdown-flashcrash went on.. All in all, BitFinex were praised for their fast and sane reaction, and for covering all (real) losses. Ente |

They need to add more tools/features to let lenders take less risk if they want to...
For example, I want my lend to be taken only to a trader that:
- setup their account with 1.5:1 leverage
- used the money to short
- used the money to long
etc etc, there is a lot of things like this that they can implement, any one discussed this before? or got any insight from them about implementing such things?
Regards
I think that topic came up already, but nothing came out of this. More pressing, it's still unclear how "everything is as much insured as we can" looks in reality and who would pay in a catastrophic meltdown. Finally, this wouldn't solve the counterparty-risk you have with all anonymous (this topic isn't resolved yet neither) websites. On the bright side: it's not possible to open positions on darkcoin. (That "total drk swaps" tablehead scares me a little, though) Ente |

Oh! Now I got it! :-)
Didn't see the "offers" and "demands", and the timestamp made me assume its a log of taken offers..
Thank you!

Bjorn, only half related, is there a list of the current swap offers?
Thank you, again, for the great site!

Any thoughts as to why rates are so far down? Total amount of loans is roughly the same as it has been and I doubt that more people have pumped USD into offers after the July 27 leverage change?
Though I suppose we don't have the stats on unlent out USD as that number would be the one to look at.
I would say because of this:  http://www.bfxdata.com/swapstats/usd.phpEnte |
