I am attempting to withdraw BTC from Electrum. The problem is when I try it asks for my google authenticator code. I do not have this. I have my seed but I mustn't have scanned the QR code after creating the seed.
How do I bring up this QR code to set up google authenticator for this transaction?
It isn't obvious from the interface what to do and information online is sparse.
Thanks in advance.
Are you using a phone right? Turn your phone off completely and try again. If you still have the problem, if you have the seed you can disable 2FA (i think that is what you mean by google authenticator, im not sure because i dont use any BTC software in phones). It should be like this: "File" -> "New/Restore" -> Select "Standard Wallet" or "Wallet with two-factor authentication" -> "I already have a seed" -> Paste your seed -> Select "Disable"; |

I believe it does have a GUI by default and it should be secure of course. I did never use GUI tho, there really isn't any need and it makes it easier, at least for me. You just need to run like one command to start bitcoind and that is it. GUI would just make it harder for you to pass arguments to bitcoin when you run it, but do as you wish, I can just tell you that it takes far less effort to compile Bitcoin Core without GUI and to run it. Don't worry, you really don't need to do nothing complicated, there is a reason why many people still prefer to run things in command line, it really is simpler, easier and quicker.
It may be easier for you, but it isn't easier for 99% of population man. Windows was a success and MSDos died out for a reason. And i think OpenBSD comes with no GUI and you must install it separately. https://www.youtube.com/watch?v=o_qHwc02ergThis guy makes it sound like it was a pain in the ass to get the GUI working for OpenBSD.. not sure if I want to still do this or use some Linux distro. |

I didn't really hear any controversies about Ubuntu, at least I can't find anything recent on Wikipedia at the moment and I would remember if I heard something until now. But there are other platforms considered more secure as far as I know. OpenBSD is a very simple OS that actually isn't Linux, but is Unix based. It apparently had a very few vulnerabilities in it's default installations in the past despite it's long history. The code is apparently highly and actively reviewed regularly to check for any vulnerabilities. The security is their number one goal as far as I understand and I use that OS for my own node.
I don't know about user friendly tho, that is subjective. I did compile Bitcoin Core from source and I am unaware of any packages for OpenBSD, but then again I didn't search a lot for it as I always compile Bitcoin Core from source and recommend it as well. Just follow the instructions in the Bitcoin Core documentation in source code and you should be fine.
I have looked some youtube tutorials and OpenBSD seems to be an OS that doesn't have a GUI (like in the old times with MSDOS). Mmm no way im going to go back to that in 2017 man. I would probably make a mistake and end up doing something stupid. Can't you install a desktop and still profit from OpenBSD's security? For what it's worth: I'm just as paranoid running Linux. I actually consider it a good default, don't ever assume your computer is safe!
Well, what do you personally consider the best way to run a full node and transact with it? What OS specifically and what security measures must be taken? |

A lot of the time, private keys will get stolen contemptuously with an account getting hacked so this won’t necessarily solve anything.
Also, the administration will look at a lot more than the signed message when considering to recover an account.
Such as what? If someone delivers couple of signed messages with a couple of BTC addresses posted here, what other proof could you need? If that doesn't cut it then nothing would. Like I said, most people getting their accounts stolen is due their emails getting hacked. Getting your private keys stolen is much harder if you are keeping them safe. |

I just made a thread asking about a proper Linux distribution to install a safe Bitcoin Core node in there that I would keep updated and would use to transact too. I was wondering how to set this up properly. https://bitcointalk.org/index.php?topic=2331605.0I have my doubts. Where should I allocate the blockchain files at? At the same partition as the Linux OS is installed? what happens when I run out of space? I want to buy a 1TB SSD m.2 disk, but I don't want to fill it with the blockchain since I got a Windows partition with video editing programs, games and other things that would profit more from the extra speed of the SSD, yet I still want to take advantage of it's fast speed to install the Linux OS partition there along with my Windows partition. Should I get a dedicated 1TB 7200rpm HDD only for the blockchain and wallet files since it's cheaper? I don't know how to set it up. |

I don't have much experience with Linux, so I would like to know what is a safe and reliable distro that at the same time is user friendly for a regular Windows user, in order to be able to run a full Bitcoin Core node and forget about constantly being paranoid of doing so in Windows.
I heard Ubuntu is really user friendly but I also heard that Ubuntu is no longer considered safe because it got bought by some sort corporation or something like that. Im not sure about the details but I remember reading something dodgy about Ubuntu.
I would also like to know if I can re-use my existing "blocks" and "chainstate" folders of my Bitcoin Core windows folder into the the Linux folder to not have to go through the entire thing from scratch.

Since a few days we have already got an excellent solution against hacking accounts. When email is changed, a link is sent to previous email and we can lock our account during two weeks. The same happens on password change and we can see already good results. In this way we are also able to change email if email account is lost.
This implies that you didn't get your email account hacked/lost too. Sometimes people register in forum with email addresses that they don't usually use, only created exclusively to register at a particular place. This could lead to your email being expired due not login in in 6 amount of time, which could lead to not being able to recover your account. If you also got a BTC address, you could get better chances at recovering it than any other method (assuming that the admins don't take 2 years to check your evidence..) so I don't see how the registration process should at least recommend users to enter a BTC address in case you get hacked. |

Most people goes for SPV clients as opposed to full nodes. It should be rather fast (few hours) if you use a pretty new hardware. IIRC, Core 0.15.0 did have significant improvement in terms of the synchronization time. So did 0.13.0, 0.14.0.
I don't consider SPV safe, which is why I want to improve my full node experience as much as possible. Core has indeed gotten faster lately. In the early Bitcoin-QT, with this same computer im using now, it was a pain in the ass to run. Nowadays I can run it, the RAM usage is only about 500MB, but I would like a faster sync time and I guess a modern CPU will be a big improvement. Intel. AMD is still lacking behind in terms of performance. If the application uses more cores effectively, then go for AMD.
I was betting on Ryzen but it seems Intel has won the battle again? http://cpu.userbenchmark.com/Compare/Intel-Core-i7-8700K-vs-AMD-Ryzen-7-1700X/3937vs3915The Ryzen got 2 more cores and 16 threads but im not sure if there are any programs were it would be worth it. Intel wins on every department it seems. I got some hobbies such as video editing and music but im not even sure if these extra cores would make much of a difference. M.2 SSD is definitely faster than both SATA SSD and HDD. However, the cost would be a concern. If you have the budget, go for M.2+ HDD else, go to SSD + HDD. You can store those files which you don't really access on your HDD.
It seems for 150 extra bucks you can get the m2 SSD 1TB compared to the SATA3 SSD 1TB price so I may go for it, apparently m.2 is blazing fast. |

Looking forward to upgrading my computer for christmas and I was wondering if someone got some bechmarks with CPU's speeds when it comes to syncing the blockchain.
I've seen bechmarks of graphic cards for mining, in fact this industry is only going up with kids buying GPU's to mine altcoins, but im just interested in syncing my Bitcoin Core node faster.
Currently I got an old 2008 QuadCore so I expect a big increase in speed. I also got 8 GB of DDR2 ram.
Should I go for Intel or AMD? I was considering the i7-8700K 3.7Ghz which goes for around $440 and 2 pairs of 16GB DDR4 (Kingston HyperX Fury White DDR4 2133Mhz PC4-17000 32GB 2x16GB CL14) for around $300. This should be an awesome increase in speed.
I would also need a new motherboard.
Is it worth going from SSD SATA to SSD m2 or hard disk is no that relevant?
Please help me choose a nice upgrade.

So in these countries is illegal to invest in ICOs but it's legal to buy/trade tokens once they are in exchanges, right?
They are considered as securities by some countries, so if you are not authorized to deliver securities, you are in a way that im not really exactly how, being part of illegal activity (it should be the people hosting the ICO, not the ones buying it in my opinion). The smartest people saw this coming a long time ago. But there will always ways to circumvent this, so ICOs aren't going to stop. Just check from where the ICO is being hosted, and if you are sure that the spot allows for ICOs then go for it. Use an VPN as needed to circumvent any local limitations if needed. |

Given that more and more people keep losing their account and the only 100% certain verification that a new account can claim to own an older account is if the older account got an unedited, quoted or locked BTC address somewhere... why not ask for a BTC address during registration?
Most people learn about BTC addresses being an useful way to verify your ownership when it's too late, so it comes down to luck if you posted your BTC address somewhere or not, so it should just be a part of the registration process, or at least make it optional and clearly say that if you don't add a BTC address it may be a problem if you get hacked.
Can admins see the history of any changes in the "Bitcoin address:" thing on "Profile"?

Sincerely I don't see any kind of connections with Catalonia and Btc Prices because when the referendum happened price didnt make any great moving. But I think it may affect Bitcoin indirectly because of the fiat changing price, and the recently movement of Bitcoin is because of that fork thing which can be back to stabilize after 25th october.
Catalonia has declared independence today, it is all over the news in several countries now. Europe is going to go throught a major crisis with this I think. People living in Catalonia are going to get scared about bail ins, so there is a big incentive to have your wealth in bitcoin right now if you live in Catalonia. Who wants to leave their money in a republic with no international recognition and in the hands of some communists? Once again bitcoin holders will profit and fiat holders will suffer from all of this. Most likely the central government of spain will soon pass some serious measures to establish order which will only escalate the problem to an higher level, but if you are holding your wealth in bitcoin you are unaffected. It is the wonders of holding an asset that belongs to no country. Bitcoin is a pretty nifty technology for escaping bad fiat systems in times of turmoil, eh? It just goes to show that any sort of "Union" between regions will fail, regionalism is too strong and most governments don't seem to want to accept that people have ties to where they came from and aren't interested in locking their history, culture, or whatever else, away under the guise of being united under some banner. I'd like to see what the response is from the rest of the EU about this; if Catalonia can actually manage their independence well then there might be more regions within EU countries attempting to push for their own independence, which would be a disaster for all involved. Donald Dusk already said nothing has changed, the EU still sees Spain as the only interlocutor, which means is not recognized as a republic. Angela Merkel and Macron have also said that the so called Catalonian Republic is not recognized. Legal situation for Catalonians is now very confuse and they should be worried about their wealth. Those that did their homework and move it to bitcoin are now safe. You have to do this before it happens, not the day it happens, but there's still time for them before they try to stop withdraws from banks. |

I was wondering. What is stopping exchanges that don't support the new BTG using your bitcoin and claiming it for them selves, without you ever knowing about it?
Like Bittrex and cryptopia, they didn't support the Bitcoin Gold. But what is stopping them to use your bitcoin to collect bitcoin gold, without you ever knowing?
What is your opinion guys?
Yes they are. Every exchange that doesn't list forks is stealing a certain amount of money that you would have received if you held your coins in your wallet as you should. You can't bitch and moan about your forkcoins being lost if you are lazy enough to leave your BTC in exchanges. You can't also expect exchanges to list every fork under the sun. |

i find this post in Meta Section please read it Before waste your money Anyone can create a Bitcoin-derived altcoin like "Bitcoin Gold" (BTG) at any time with no cost. BTG is a scammy cash-grab with no ideology and no economic support, not something serious like Bcash was. That's not to say that it's impossible to make money by trading it, just like with other scamcoins, but I'm not going to get into the habit of writing announcements and guidance for every Bitcoin-derived scamcoin. If you want to do a dangerous replay-unprotected coin-split maneuver in order to claim tiny fractions of your BTC in airdrop value, that's on you.
I will write a guide later for B2X (split time in mid-November), which is more serious. After that, the bar is going to be awfully high to get me to announce similar things.
I'm believing it, the fact that bitcoin gold doesn't have any backers or support. I think that about those miners are not interested to mine bitcoin gold shit. There are something wrong about that. Bitcoin gold doesn't have anything rather than the future will worth zero value. The gold developer just another scammer that as used the bitcoinhype to give their own advantages from there. so why no one talk about this Before 25/10 till theymos take after fork start Not even B2X is serious at this point. Brian Armstrong is a god damn idiot that deserves bankruptcy, he is going to support the wrong chain and newbies are going to get confused and dump their B2X thinking they are getting BTC but it will be the opposite. Coinbase needs to disappear for being such jackasses. If you are a newbie, I recommend that you don't do anything a good week after the fork to see where we are at. Only when you are sure that there are no replay attacks possible should you access the coins, but of course, they may use this time of lack of dumping to pump their shitcoin2x... this is an strategy of attack against BTC but im sure the smart people with tons of BTC aren't going to let them win. |

Will the bitcoin price decline after bitcoin gold?
I read that many now will continue to sell bitcoin and buy altcoins.
Should I buy bitcoin now or wait?
I think you have missed the opportunity to buy bitcoin when the price is low around $5200-$5300 just right after the hard fork. The price is going up again and moving to $5700. The selling of bitcoin cash and the subsequent shifting back to altcoins is over I think. Because bitcoin is now back to $5700 and altcoins are all going green now. But if you really do not want to missed the boat again, I will advise you to buy bitcoin today, specially if you are really on it for the long haul. And then once their is a price correction, you can buy more bitcoins for yourself. At least your in a good position to really gain returns when bitcoin price goes to $6000-$7000 before the end of the year. And if the price didn't reach that but instead experienced dip, then your strategy is to buy more. So its a win-win situation for you. We are at around $5950 now, it's going to break out upwards if my analysis is correct, I see an ascending triangle. The speculation with the fork is over, the dip already happened, now I see us hitting a new all time high before November 19th when the segwit2x hardfork will happen. Once the segwit2x scam is defeated, after a dip, we will go towards $8000, we could even hit $10000 by christmas, depending on how much damage Jeff Garzik and the rest of idiots behind segwit2x cause to the price. |

I asked for something like this ages ago I think, and I was told that it was not implemented because email wasn't considered safe, since emails tends to expire, and with expiration if you don't notice it, someone could re-register the same email and take control of your account by requesting a new password. I don't see any evidence to claim inside jobs tho. The only thing that grinds my gears a bit is when people present enough evidence that someone owns a certain account by signing BTC addresses which are found in locked threads and unedited posts, but they still take ages to recover it, not sure what the deal with this is but im hoping all these cases get eventually resolved and people are recovering their accounts. |

Which one made you the most money, or do you believe is the best tech?  I have never bought any ICO, but Ethereum itself was an ICO, and im sure this one was the highest paying ICO ever. Stratis also delivered insanely big gains thanks to it going under the radar. After Stratis, the ICO bubble started, more and more people got into ICOs, therefore there was less availability of the cake for everyone, so the possibilities to get rich went low because ICOs got quickly crowded. Just look at coins like Bancor, the ICO was huge, so this ended up in an overbought token that just keeps dumping. |

I have noticed how in the charts, the orange line that represents the gains vs bitcoin are getting much lower. Sometimes coins pump really big when it comes to USD, but you don't make that many BTC gains anymore, example: https://coinmarketcap.com/currencies/clams/Notice how the all time high in BTC in august 2015 is similar to the all time high in USD that happened recently last week. So what does this tell us? making gains in BTC is harder. Have you noticed any altcoins that have done all time highs against BTC recently? |

Bitcoingold was a bit of a scam, taking advantage of people who wanted free coins and who imagined that it would be like bitcoincash.
The gold developers are so clueless, they are begging to hire people who can do replay protection - which goes to show that they're opportunistic marketers rather than genuine developers.
Well, these holding BTC will get Bitcoin Gold too, so they will get free coins too, in this regard, the promise is meet. The problem is the lack of replay protection being rushed by developers that cannot properly code so they have to hire it as you said, but not only that, the fact that there's a 2 week premine turn it into a joke. Wasn't Bitcoin Cash premined too? I remember Bitmain said they would premine it on their blog, or they were talking about another hypothetical fork? I have lost count with so many forks as of late. |
