There are various sites that show exchange rate charts for different exchanges. I normally look at bitcoinity ( http://bitcoinity.org/markets) but tastes vary, so if you find one that suits you better then use that. Sorry that you bought BTC when the price was higher, my advice would be to hold them at least until the price is high enough again that you can sell without a loss. Then you should decide whether you want to keep them while they are getting more valuable, or whether the risk is too high for you. But don't sell at a loss (unless you're really desperate for cash, which somewhat indicates that you invested more in BTC than you should have done). The current exchange rate of between 350 and 400 Dollar/BTC has been more or less stable for a number of weeks. Some believe such stability is good, some would like to see much higher exchange rates. I believe it will go up sooner or later, but that will probably take some time. My bet is that we will see a new all time high in 2015, but don't depend on my gut feeling for your financial decisions! Onkel Paul By the way, of course exchange rate charts will only show the past, not the future. If you find one that accurately predicts the future, please tell us - most of us would even pay a bit for such information! |

People will pay as much for 1 BTC (or for 1 mBTC) as they think it's worth when they buy it, this includes actual value (what can you buy with it?) as well as speculative value (how much will it be worth in a year?)
If at one point in time you can get a great smartphone for 25 mBTC then $10k for 1 BTC is not too much, so you will gladly pay $250 for 25mBTC to get your smartphone. If you want to buy a car that's offered for 2 BTC youll probably even buy 2 BTC for $20k.
You will just be a bit mad that you did not buy some BTC when they were less than $400.

Hast du es mal mit "Google Notizen" oder Evernote probiert?
Wahrscheinlich tun die Apps nicht 100% das was du dir wünschst (hab sie selbst noch nicht probiert, da mein Phone zu klein ist), aber die Arbeitsweise ein bisschen an die Tools anpassen wirst du immer müssen, wenn du etwas einsetzt, das du nicht selbst designt hast.

Trust level displayed for any user depends on whether the accounts who gave feedback are in your trust list.
Most users don't have an individual trust list, so the default trust is used, and it seems that none of the prople who gave you positive feedback are in default trust.
Anyway, your feedback history is pretty nice, good job!

Actually, half finished projects are in some cases ideal - a lot of the groundwork has been done, but you get to decide on the final appearance.
So, selling a half-finished project isn't a bad idea. But I don't have enough time to finish and run a project like this...

Ist glaube ich bis jetzt das ruhigste bitcoin Jahr oder?^^
So kann man das auch sagen. Der korrektere Ausdruck ist allerdings "Tote Hose". Wobei ich die Seitwärtsbewegung mit einem lachenden und einem weinenden Auge sehe - klar fände ich es gut, wenn mein kleiner Bitcoin-Bestand gaaanz viel wert wäre, aber eine Verringerung der Volatilität ist für eine Wahrnehmung von BTC als ernstzunehmendes Zahlungsmittel mit kalkulierbarem Werterhalt extrem wichtig. Die Spekulanten haben den Kurs nach oben gebracht, das ist auch in Ordnung so, aber auf Dauer sollten sie nicht mit ihm Achterbahn fahren. Das heißt nicht, dass ich den jetzigen Kurs schon für den "richtigen" halte, da geht noch einiges nach oben. Aber schön ruhig und gesittet bitte :-) Onkel Paul |

The moral of the story is to never share your true net worth or wealth online in any environment of forum.
There are two secrets to certain success: 1. Don't share all your secrets ... Onkel Paul |

In bitcoins there is no middleman, the middleman is a public blockchain where each transaction is written following cryptography rules.
Perhaps he meant folks who buy bitcoin on exchanges and sell on localbitcoins for a premium. I'm pretty sure you can make serious money that way if you dodge AML/KYC rules... Onkel Paul |

Congratulation but how all of you can calculate the period of time remaining to be senior or hero
See https://bitcointalk.org/index.php?topic=178608.0Basically, if you ignore this two-week period stuff, you get one activity point per day as long as you're posting often enough. So the 240 activity points to get from Senior to Hero corresponds to 240 days = roughly 8 months. Onkel Paul |

Is there any site where i cam learn gambling.
Because once i used one site on where i lost .01BTC.
The first thing (and you can learn that one even without a gambling site) is that there's no way to consistently win at gambling (at least on dice, roulette and other truly random games - poker is an entirely different thing). Some sites are more or less fair: The take a clearly stated house edge, and winnings are distributed fairly according to the probabilities of the game. Some sites cheat: They let you win a little on the first games (maybe even "give" you some money to play with) but when you're on the hook, you pay it back trying to repeat your winning strain. Even if you gamble at a fair site, don't expect a net win on average. If you win a bit, enjoy it, and if you lose a bit, think of it as a fair price for the fun you had. If you're not having fun, stop immediately! Don't try to make up for your losses, you can't force a win! Onkel Paul |

We use paypal, so the order processes immediately.
Wot? Paypal  ? Not BTC? Heretic  !Seriously, good luck with the project. The paper looks really nice! Too bad my family isn't into bitcoins, so I'm not a prospective customer... Onkel Paul |

Exactly that is what I meant to say. There must be a starting point. If the majority controls the hash rate, you can't just come up and say now I have a new rule in place and it needs to be implemented. Take for example if the current block size is 250kb and a hard fork is required to change it to 1mb for example, how would that be made valid??
And that is where the speculation on a hidden secret code comes about. It's like a passphare that gives authority to one single node to dictate the terms.
Just because you don't know how something works does not mean that you can create a conspiracy theory out of thin air that will somehow be true. There is no secret code. If developers are under the impression that some change in the protocol is needed, they'd first discuss it and then propose it to the community. If there is some kind of consensus (for example, if a majority of mining operations say "yeah let's do it") the change is implemented into bitcoin core and possibly alternative node implementations, typically with a (future) block number after which the change will become active, to give nodes time to update their software. Once the block number has been reached, it depends on whether a majority of miners are actually using the new protocol version. If only some have upgraded, the "fork" will fizzle and fail because the main blockchain continues to adhere to the old protocol. If the majority use the new rules, only those who did not upgrade are left behind and will be unable to mine blocks that are accepted by the rest of the network. In either case, one version of the protocol "wins", and whoever uses the other version has a strong incentive to switch because otherwise he'd be unable to produce valid blocks. Onkel Paul |

dont you guys use an antivirus  ?? Antivirus doesn't always help - it's best against widely distributed older viruses, but often would not help against specialized trojans. Brain 1.0 is the best antivirus against most threats - it just does not work automatically, you need to explicitly use it. Onkel Paul |

Yup, this is great! I assume their mixing service is equally reliable  - did not have a need for it myself. Onkel Paul |

Ah, ok, this is indeed bad, thanks for the explanation!
So as upgrading the OS is not an option (Samsung isn't really eager to supply updates, and the phone isn't really supported by Cyanogenmod), I'm just waiting for the new phone. Whatever transactions I need to do in the meantime can be done with bitcoin core on my desktop.

That's true but by buying the recipes one can show appreciation for the work and thought put into it (I'm assuming that they were not simply copied from somewhere). Some people are content with positive blog comments, some like to see some monetary appreciation, both is fine with me. Onkel Paul |

Hi,
after updating, Mycelium tells me that my Android 2.2 phone is unsupported due to a bug in random number creation on that OS version.
Could you share some technical details so I can estimate my risk? (or did I miss an announcement somewhere?)
Since I'll be switching to a new phone in a few weeks anyway (Christmas is just around the corner) I could probably live with avoiding to create new transactions and just initializing from the backup once I have the new phone.

You should probably try to understand how transactions in the blockchain work.
Every transaction takes a number of inputs and creates a number of outputs (for a moment, I'm ignoring the block-reward transactions that the miners produce).
The sum of inputs equals sum of outputs plus miners fee for the transaction.
The inputs of a transaction are outputs of previous transactions that are in the blockchain. Since you can only include an output entirely, it is possible that the amount available from the inputs does not match the desired outputs, in which case you would generate a "change" output that goes to an address in your wallet. Whether this is a previously used or fresh address does not make a big difference, although it is generally advisable to use fresh addresses for improved security and privacy.
In your example, your first transaction would have a number of inputs totalling 100 BTC from address A (the number of inputs does not matter much except that a large number of inputs results in a large size of the transaction, which increases the required miners fee). The transaction has 100 outputs of 1 BTC each to 100 addresses B1 to B100.
Your second example would have 100 inputs consuming these 100 outputs and one output of its own with C as the target. This kind of bitcoin shuffling does not make much sense, but anyway, we're just following the example.
Now your question seems a little confused: "can i spend 100 times 1 BTC from A then immediately" does not make sense since you already spent 100 BTC from A. Do you mean that you want to spend 100 BTC from C, or do you mean that there would be 100 BTC left in A that you want to spend now?
Either way is possible - your inputs only must refer to outputs of transactions that are in the blockchain already.
There's one special case: If a transaction refers to outputs from another transaction that is not already in the blockchain, both transactions may be included in a block together, so it is possible to spend outputs from a transaction that has not been confirmed yet. I think most wallets only allow this for "change" outputs that they have generated themselves.
In any case, it's best not to confuse wallets, addresses and transaction outputs when reasoning about bitcoin transactions. Try to get a grip on these concepts, then your questions make a lot more sense (and some may already be answered).
Onkel Paul.

I think the only thing that can make bitcoin mining feasible at the moment is ultra-cheap electricity. In addition, you need to get miners at a good price while their performance is still up to par. Difficulty is rising all the time, which reduces the bitcoin output of your miners very quickly. The point where they don't yield a revenue even with cheap energy comes much too soon.
