i personally know that there are many wallet options that do not need the full ledge. i had them download a full chain wallet because they are students and i wanted them to be able to take full advantage of all cli commands and such and not be dependent upon a gui. the thought just came to mind when i described the block chain comparing it to my checkbook. I thought to myself that i have a drawer with at least the last ten checkbook ledgers, they fill up, i replace it with a new one. i work with local businesses in various ways and when i talk about bitcoin i hear the gambit of excuses, complaints and other "reasons" why a certain person or business does not want to use it. as we move closer and closer to a more full acceptance of bitcoin, i constantly try to compare new technology advances with the complaints that hold people back. this was merely an attempt to get people thinking about possible changes in newer side coins or coins. I did not mean to offend anyone and i am far from expert in crypto and bitcoin.
You can probably use most of the functions that Bitcoin-cli has, if there is an SPV client that offers this. It is easy to cheat the wallet client if you don't have to prove that the blocks are branched out from the genesis block. Businesses should run a full node, to be safe. As long as bandwidth isn't too much of a problem, (100+GB for once) there is no issues since you can still prune it. Btw, changed my original post slightly. as far as the students, what i really want is for them to have an isolated coin network, full nodes and to learn to build the tx's from scratch, perform any wallet and/or mining related function from command line and fully understand. i only get a week of their time though. our society has a major issue with technology being too easy sometimes. software performing all the functions and when something goes wrong, they do not know how to fix it. if you use paypal and jack up your account, they will help you fix it. bitcoin, being decentralized, really needs for people to have at least some clue as to how to do something besides push a button. Maybe run on testnet then. Or even testnet in a box. Avoids the waiting etc. |

I have a question . If my mobile that i used for 2AF got lost or broken is there anyway to transfer the 2AF i have on it to a new phone?
What 2fa software were you using? Authy? Google Authenticator? Something else? (Btw, dev and tech seems like the wrong section). And what website is this for? |

In 2009 bitcoin hit the electronic currency world by surprise and later captured the attention of the masses and information technology companies. Coinidol.com investigates why most people are still too scared to use bitcoin as their main currency for day-to-day business. In Africa, Asia and South and Central America, there is widespread poverty brought about by underdevelopment and low levels of education. Bitcoin is a currency of the elite, those who can read and write and those who are connected to the internet which is lacking in most regions in these continents. You can read the full article here: https://coinidol.com/why-bitcoin-scares-society/I think I'd add to one portion: In Africa, Asia, and South and Central America there is widespread poverty brought about by a lack of the rule of law, socialism, communism, authoritarianism, and totalitarianism not to mention a group of wealth-hungry and power hungry people who are willing to destroy their countries to enrich and empower themselves via corruption, outright theft, inflation and policies only designed to retain power. All the while demagoguing the populace to blame someone else for the failures of centralized, state planned policies that stifle freedom and liberty. See Venezuela, Brazil, North Korea, Nigeria, Cuba and many others for examples of each.

is it normal that the balance is 0 ? or i have to wait for armory to download all the blockchain to see me real balance?
Since Armory depends on Bitcoin Core, it won't show the balance until it reaches the block where bitcoins were transferred to those addresses. However as onnz423 says above, if you can export the private (and perhaps public keys) from Armory, then you can import them elsewhere, such as Electrum, and go from there. |

You might try updating to 0.13.2 first and see if it is the same error - it seems as if you thought you had upgrade, but actually didn't:
>2017-01-15 00:21:14 Bitcoin version v0.12.1 (2016-04-11 13:01:43 +0200)
Scroll down farther. He's using 0.13.2. ... Ah, didn't see there were multiple days! Looks like 4GB should be okay. |

Now i have only hard drive formatted 5-6 times.
I already tried using the data recovery software, recommended me to go to a data recovery expert?
One thing I didn't see you answer was whether after you formatted it 5-6 times, did you use the drive in between? e.g. did you format, format, format, format, format and then nothing? or did you format, use for a year, format, use for a year, format, use for a year etc? If it is the former, then it is much more likely you could have a chance to recover as compared to the latter. In fact, if it is the former, you'd likely have a reasonable chance to recover and it would be worth spending the money to hire a recovery service to do so. If it is the latter, it (as others have said) will be almost impossible to recover after years of usage. |

[...]Other than that, I only know BTC-E as a decent and major exchange that doesn't require you to sign up with any personal details. Yes, there are exchanges like Bittrex that do the same but I don't trust them at all. FIY https://bittrex.zendesk.com/hc/en-us/articles/215282838--Draft-Frequently-asked-questions-about-account-verificationThis means Bittrex is changing its way to deal with anonymous users. They are still moving forward to it. Personally I'm still keeping a legacy account opened long ago: but I know that new users already fall into the new verification policy (basic as the first level). Things change soon in crypto. A selfie? What's next? A medical record to verify you're sane? I don't know about you but if all exchanges start doing it I'm not even going to consider buying fiat. I don't trust them enough to submit all my personal data to some private exchange with low security and then worry that it can get hacked or sold by the exchange itself. Live streamed Colonoscopy will be next to verify you by DNA. More BS will just discourage people from converting back into fiat making it more difficult to track. And will encourage better privacy protections in he network. |

Im just curious. What is ETF? Anyway, it would be great if that $300 million really happen. It would be beneficial for us and so as the investors. If thats happen, it may attract more investors because tgey are a huge company. Wow! $300 million is really huge. Hope to see more of this in the future. And the price pumps again.
ETF = Exchange-Traded Fund https://en.m.wikipedia.org/wiki/Exchange-traded_fund |

Actually, what I want to know is the working logic of wallets. For example new altcoins are coming out. Different wallets are being developed for these altcoins.
Is it like the bitcoin wallets in the logic of the wallets developed for the new altcoins?
Depending on the amount of detail of the logic you want, looking at the source code of some open source wallets might be your best bet. |

FUD is the reason it might not get approved. Gotta love the nanny-state Luddite, authoritarians in charge. If $300 million comes in during the first week, the impact would be immense. $300,000,000 at $1000/bitcoin (to make the numbers easy) means 300,000 (more than that at $800-850) bitcoins would be required. New coins are mined at ~1800/day so that is 166 2/3 days (about 5.5 months!) of new supply. So, to purchase that much would surely impact the market in a huge way. Now they may be selling some of their own coins to it, so that would decrease the amount that would need to be purchased, but any way you look at it, if approved AND if people invest in it at the rates they project, the price effect would be large. And once it starts, momentum players could follow. The smart ones will realize that the earlier you get in the more upside there is. |

With the inflation rate in Nigeria it isn't surprising those in power would be worried about something like bitcoin.

Authoritarians of all stripes - fascists, communists, socialists, cronys etc - are the same the world over. They don't like freedom because it threatens their power and wealth and so they'll use just about any excuse to "regulate it". Their motto is to "never let a good crisis go to waste." The EU is no exception here.

This is not an entirely bad report on what is happening in China. The Main focus is that the " Chinese authorities have taken note of the move toward bitcoin, and they are trying to throw cold water on the coin in order to tamp down capital outflows and help the yuan. " So they shine the light on Bitcoin exchanges to scare people, in the hope that less capital will flow out of the country. This will not stop Bitcoin or it's users from finding ways to buy/sell and trade bitcoins.
If this was done before Mt Gox happened, then irregularities would have been detected in advance and we might not have had the Mt Gox incident. The regulated exchanges must function as "safe" area for people to trade bitcoins and if they fail in doing this, we will suffer the same fate as we did with the aftermath of Mt Gox. The government have a duty to protect the consumer from questionable practices or services.
The Chinese authoritarian communists need to control people to keep their power and wealth. To control people, they control the capital and speech. Hence they fear bitcoin because it isn't subject to their control (except it too many miners are concentrated there). |

No offense OP, but this post is just begging to get HACKED. May I recommend upping your security a bit?
Can you clarify the intent of your comment, because I am a little less understand what you want to convey? why can it give rise to hack? Because I think that people generally, if they died of course they do not want to lose their property. It would be better if someone close like a family would have the money, or may be donated to someone in need. thank you Anyone bothering to include bitcoin in an inheritance must have a bit of coin, no? And, you kind of gave away the secrets of how you secured the coin. I doubt your identity and location are secret? You've painted a target on your back. Just sayin'. The article was good though, and no disrespect! Finally I hope your wife never "goes rogue" on you. Because I've had a couple of women f**k around behind my back and then rob me of everything they could get their hands on... Sorry to be cynical. All good points. It isn't cynical, it is reality. 😀 OP could always use nlocktime to create a transaction three years (for example) in the future. Put that aside for his wife/spouse. Then regenerate it every 2.5 years. If something happens, the spouse may have to wait between 6 months and 3 years to get access to the coins because the transaction wouldn't be valid for that period, but even if the transaction is stolen, no one can steal the coins before that time period and OP can move the coins if the nkocktime'd transaction goes missing. |

SearchTrade is a website that has a google search which you get paid 20 satoshis ever time you do a search.
Here is something from the Searchtrade site:
Minimum Withdrawal Amount : 0.00100000 BTC.
Withdrawal Fees : 0.00036500 BTC.
so they are taking 30% of your searches in order to get paid and looks like you would
be using it about a year or two, at least to reach the payout.
Searchtrade also doesn't have a good BTCtalk track record. Not much activity in the last
year.
It seems like a good idea, preferably one that might be bought out by someone who can make
it more feasible. Most people know today that high payouts are a no go in affiliate work, faucets
and so on. But can this idea be legally copied by someone? I think the idea was around before it
was converted to BTC.
Trademarks don't protect ideas, but marks/designs etc used in trade. See https://en.wikipedia.org/wiki/TrademarkCopyrights don't protect ideas, they protect original works. See https://en.wikipedia.org/wiki/CopyrightPatents protect an inventor etc of an invention. See https://en.wikipedia.org/wiki/PatentSo, perhaps they could have a patent on their specific implementation, but it seems extremely unlikely they could prevent a different implementation. It is possible to search and see though. |

Just make a paper wallet at bitaddress.org. there you can make a paper wallet with BIP38. With this you need to set a password which encrypt the private key. So you just see the private key but without password it's useless.
If you are really concerned about security, download they bitaddress.org web site from GitHub ( https://github.com/pointbiz/bitaddress.org) and then run it while offline and in private mode on the browser - at minimum. Quit the browser after running it. Maybe even run it from a new user account on the machine. (Or from a USB boot device that is only used off-line.) There are ways that are even more safe, but it is not recommend to do it online for obvious reasons. |

Yeah, gotta keep the Chinese people in the dark about how the gov is robbing them through devaluation daily. This should only spur more use of bitcoin for people who are paying attention. |

3) Koblitz Curve (@ 13:10)
At 13:10 he claims that the Koblitz Curve had some signature leakages, so he uses an R curve (571 bit), which he claims that has the highest quantum security to this date.
I don't know enough about this topic to comment on it. gmaxwell discovered a security issue with the R curve while scracthing his head about why Satoshi had opted for the Koblitz curve version of ECDSA instead of the R curve (the R curve is recommended by NIST, whereas the K curve was not). Cannot remember the details, I'm sure someone can. There has been some discussion and evidence that the supposedly random constants of secp256r1 may have been finessed by the NSA. Edit: Some reading: https://bitcointalk.org/index.php?topic=151120.0https://chrispacia.wordpress.com/2013/10/30/nsa-backdoors-and-bitcoin/ |
