Where is the option to import private keys? I saw various pages mentioning that it is located in the wallet properties page but I can't seem to find it.
Also, is there a way to import a public key as a "Watch only" type of address?
You have to create a wallet first, and then select the wallet into which you want to import the keys. From the wallet properties, there's an option on the bottom right for importing private keys. Unfortunately, there is no way to import public keys into a watch-only wallet. There's a couple reasons for this, and not all of them are laziness  I finally am in the process of switching to armory! A few questions.. a) I guess no news about "importing" an address when only the public address is known? I imagine this should be possible, as we have the blockchain with all transactions of this address? edit: It doesn't have to be a watch-only-wallet. Would it be more possible to have a whole new type of "wallet" for this? b) Imported addresses: The paper backup warns that imported addresses are not included in the paper backup. Are they included in the digital backup / wallet file? c) and OT: I wish to have bitcoind always running in background. Does anyone know a way to "connect" bitcoin-qt to the running bitcoind, instead of armory, when armory is closed? I would like that option, as I have a lot of wallets from bitcoin-qt left, and start all fresh on armory. And yes, that's nothing I expect the programmer of armory to code ;-) Thank you for this nice client! I already love it, never restarting the client again to switch wallets! :-) Also, what is currently the limiting factor in armory's development? Time, funds, tasks, coders? Ente |

This is absolutely gorgeous news!
Chapeau to all you already achieved, and best of success to all there will come!
What do you think about this:
a) I receive bitcoins on one of my account addresses
b) They are immediately and automatically converted to Eur
c) Those Eur are left in the account, or automatically transferred to another bankaccount every x days or once y Eur are accumulated
Basically the all-in-one hassle-free NGO Bitcoin donation program! :-)

Thank you for showing your situation and findings, gweedo.
Indeed you are talking a whole different level than I am.. :-)

Bitcoind is either a) the RPC server or b) an RPC client.
Bitcoin-Qt is a GUI + optionally the RPC server.
The error you're getting probably means you're already running bitcoind as RPC server, so you can't start Bitcoin-Qt in server mode as well.
Shut bitcoind down (./bitcoind stop), start Bitcoin-Qt with -server, and after that point you can send RPC commands to the GUI.
Aaah, now I get it! So I was in fact running bitcoind and then trying to start bitcoin-qt as a server, which can't work. So, my new question, now, is: Can I connect bitcoin-qt as a "client" to a constantly running bitcoind? As I understand, that's what OP was actually asking. He probably changed his plans with "-server". Now I think this isn't possible at all.. Then I would write a script to stop bitcoind and start bitcoin-qt automatically, when needed. Ente |

Absolutely. The price swings are so quick and random, with comparably small movement over the whole day. And then the small liquidity. It is easy to, for example, sell 1000 BTC over the opening price of a day, and then buy again one minute before the bitcoincharts chart switches to the next day. Rise the price with buying 600 BTC, leave the other 400 BTC right there as a miniwall. This is a sure thing. You might even do a tiny profit. The visual effect is pretty strong, as most days only show a few tens on cents movement. Of course it will be more and more difficult do do this on following days.. You can manipulate the (surprisingly large!) "random movements", but once you have to "work against the masses" you pay a lot. So, is the time right that a small sparc sets everything on fire? Then this is an easy and effective thing. If you don't hit the right time, you are just redistributing your bitcoins. Did it a few times, just to try, and it works. It cost me something like 10 bitcoins, with a strong effect on thecharts. Did it have any influence? No idea. Of course it will get interesting once several people do this, and when bulls and bears fight over the last minutes of a day! Ente |

Run the gui with the -server switch.
Uhm, sorry for necromancy, but I can't get it to work.. /opt/bitcoin/bin/64/bitcoin-qt -server "Can't lock folder, maybe bitcoin was already started" Same with --server. I can't see any hint via --help neither. Is this still working in 0.7x? Why? I want to have the bitcoind running whenever my computer is on. Always having the blockchain up-to-date and helping the network a bit. Then connect to bitcoind via armory and bitcoin-qt, when needed. Different question: Is it safe to simply shut down linux? bitcoin-qt takes/took a bit to completely shut itself down, I don't want to corrupt anything when linux doesn't wait for bitcoind to cleanly shut down and switches off the computer..

It' a good idea, but it's better if the 0.001 BTC will be sent to the Bitcoin Faucet so a person coming to bitcointalk.org to learn about bitcoin and how to use it, will have to first ask his question somewhere else? so he can pay .001 btc to the forum The idea is that users signing up on the *bitcoin wiki* pay/solve captchas etc. Not users signing up here, on bitcointalk. I like that idea. Why should someone edit the bitcoin wiki if he doesn't even have a wallet? I too approve in sending the bitcents to the faucet. Ente |

What would be the advantage of this?
Ok right now as it is scaling is horrible in the bitcoind one way to over come this is horizontal scaling. One advantage is one bitcoind would handle all your non-wallet commands and one would keep all your funds (2 bitcoinds). Another reason is to get rid of the pressure of one wallet having all your addresses (multiple bitcoinds). Another is to keep your funds spread out. And of course the user case Vladimir which is one I haven't even thought of. As growth is happening, this is just going to be more of a issue to show up in discussions. Sorry, I still don't get it. What do you mean with scaling issues? Is one bitcoind not connected enough, too ressource-hungry, too slow, too insecure? Or is it more like a failover, or backuplink or similar? Several wallets.. Why not having all addresses in one wallet.dat, and having "virtual wallets", like groups of addresses tagged in a database or the like, and catching newly-"created" change addresses and tagging accordingly. Security? If you don't trust bitcoind enough, write/use a different one! ;-) Spreading out between several (insecure/untrusted) instances lessens the value lost for each incident, and heightens the risk it actually happens. How about, instead of a project with a bitcoind cluster, enhancing bitcoind directly to overcome the limitations you see? Ente |

Alright guys is it up or down from here in the short term?
I got burned several times before learning that those strong dips, aka corrections, after a rush, don't come any more like they did before.. My guess is a few days sideways, then the next 10% shoot. As much as my guess is worth, my latest and probably best trading decision ever is to stop speculating ;-) Ente |

Spannende Entwicklung!
Im Sinne von "Gibt dir das Leben Zitronen, mach Limo draus!"
Klingt definitiv so, als wüsstest du wo es langgeht.
Nicht, dass ich alles madig reden will, aber wo genau käme Bitcoin ins Spiel? Ausser bei der Autowerbung/Flyer, und ab und an jemand, der Bitcoin schon kennt und explizit dich verlangt? Da muss doch noch mehr drinnen sein.. Und wenn es nur ein simples "5% Rabatt bei Zahlung mit dem Handy!" (aka 5% Risikoaufschlag auf Fiat) ist, da geht noch was! Prepaid/Postpaid/Flatrate/Escrow per Bitcoin? Die rollende Wechselstube? Taxiposition in der Blockchain? :-)

Ich habe gestern erfolgreich einen NFC-Tag im Room77 installiert. Man kann jetzt bezahlen, indem man sein Boitcoin Wallet and das echte Walltet vom Room77 haelt. Fuer das Fabelhaft, Primo Maggio und Vinyl Living Room habe ich auch schon Tags vorbereitet.
Schöne Sache! Da wird sich vor allem Goonie freuen, der ist schon seit Monaten ganz heiß auf NFC! ;-) Was genau ist das? Name, Link? D.h. auf dem Chip/Tag/NFC ist nur die Bitcoinadresse hinterlegt? Per Schildbach-Wallet wird ja gleich der Rechnungsbetrag mit übertragen, per QR oder NFC.. Freut mich, dass die Entwicklung da so schön weitergeht! Ente Ich habe vorher nochmal Goonie angerufen und genau gefrag, was ich auf den Tag schreiben muss. Er weiss also bescheid.  Die Tags sind Aufkleber: "Mifare Standard 1k NFC Forum enabled". Im Moment ist nur die Adresse drauf. 1k ist dafuer eigentlich zu viel, man koennte gut auch noch was anderes darauf schreiben. Wichtig ist, dass diese Tags schreibschuetzbar sind, damit keiner die Bitcoin-Adresse austauschen kann. BTW: Auch Primo Maggio und Fabelhaft haben jetzt so einen Tag in der Geldboerse! Sehr schöne Sache, konnte mir das System mit NFC-Tag in der Wallet aka Geldbörse und NFC-fähigem Telefon schon am Bitcoin Friday ansehen. Jetzt bin ich natürlich ganz heiß drauf, auch einen solchen Tag auf mein Telefon/Geldbeutel/Hinterkopf zu kleben, mangels echter NFC-Hardware! :-) Wie ist da so der finanzielle und organisatorische Aufwand pro Tag? Als Minimum wäre ein "Ich beschreibe dir einen Tag mit deinem String und versende ihn per Post für x BTC" Service drinnen! So wie ich die Techies hier kenne würde das sehr gut ankommen! Ich glaube das Thema verdient einen eigenen Thread, das ist einfach zu cool! Bis morgen zum Stammtisch? Ente |

..deepbit mining acting strangely too not completely down but almost. Anyway I'm sure 95% percent of miners have backup pool so for me this is not the case of dropping hashrate. I don't know.. The last time deepbit was down was a year ago, one day offline because of DDOS? I don't think many have a backuppool set up. Hell, many miners won't even have noticed yet! :-) Anyway, the "difficlty" is in free fall, from 4m down to 3m already.. Let's see how this one goes! Ente |

It feels great!
Some days ago (after the last horrible trading decision) I promised to stop trading.
Normally, I would have sold already, and would have been steamrolled by the further rising price.
This time, I watched and enjoyed, and still enjoy.
So, that's how it feels for you guys! Nice! :-)
Oh, and tomorrow I won't wake up in horror, afraid to check the exchange rate - I will be all happy before even checking!

So what's the lesson? 5 letter passwords are crackable within a day by any sysadmin. 7 letters are probably crackable within a day by a botnet. 8 and more are impossible to memorize. Passwords in general, can't be considered secure anymore.
Yeah, this is incorrect. If anything it has proven to be much much more difficult to crack than it was expected. prezbo, this is only because this was the first time that such a feat was accomplished. if those bills do spread whoever did this has an infrastructure now to do it again and faster. the only secure thing would be using pass-phrases, IMHO. spiccioli Sure there is no replacement for a high entropy. However, if I understand scrypt correctly, it cannot be calculated on gpus and takes a decent amount of time to be computed on a good cpu, thus making it a lot more difficult to bruteforce passwords, even when having multiple computers at your disposal. Let's say it takes on average 0.2 seconds for one try. That would make a 7-alphanumeric character password safe for about 5 years even if someone would get 100000 decent cpus together. ..as has been stated before: You need a password strong enough to surely notice your bill was stolen and to transfer the bitcoins from your backup to a new adress.. I, personaly, think 5 (real) chars is enough for this. For me. Heck, it'll be a dictionary-word with a number or questionmark added or the like! :-) Thank you, everybody, for this entertaining show!

Thank you, istar.
Not everything is lost on bitcointalk..
Most of the people here arguing with "statistics" and "variance" and "secure" have no fkn clue what they are talking about.
I could go on for hours about what other necessary things greenpeace do, what other problems there are with nuclear power, and what the real alternatives to coal are.
I will safe my breath and just say:
Yes, greenpeace accepting bitcoins would be nice.

Ich empfehle dir mal genau durchzurechnen, ob sich (heutige) [billige] LED-Lampen lohnen.. Energieeffizienz
Leuchtstofflampen erreichen eine Lichtausbeute von etwa 45 bis 100 Lumen pro Watt (zum Vergleich: normale Glühlampe: ca. 10–15 lm/W) und haben somit eine hohe Energieeffizienz, die allerdings von Schwefellampen (95 lm/W) und Natriumdampflampen (150 lm/W) – bei schlechterem Farbwiedergabeindex – und Metallhalogendampf-Hochdruckentladungslampen übertroffen wird.
Lichtstärke 450 lm
Leistung 7.5 W
..macht 60lm/w, wenn die Herstellerangaben stimmen. Natürlich haben LEDs noch andere Vorteile. Also: Welches Problem möchtest du lösen? :-) edit: Und so insgesamt sind 450lm auch nicht so irre.. Also nicht genug für Räume, in denen man sich aufhält. Flur geht klar mit einer Leuchte. Ente |
