Hi DarkStar. Can you change my payment address until the forks are over to this one: 13yJptq5EhUekbsTVPP6BdZPA4daJBCGgK - my freebitco.in address - i've posted it over a week ago in the forum here anyway? (I'll remind you when I'd like it changing back and if there's any issues you can continue paying to this one).
I can't sign this address as I have no control over it however I can sign my other one if necessary as that is the one I have control of if necessary (the one you currently pay to and can pay to again after the segwit2x fork).
Thanks!

NO. I noticed lots of people use electrum. It creates a watching only wallet using the public key handed to it from ledger and creates a transaction in raw form that the ledger can then sign.
Aha! Another piece of the puzzle - thanks. As a Ledger n00b, I've not quite fit all the pieces together as of yet. The available official documentation on nano s is either sketchy, or poorly organized. I have not yet hit on this possibility on their website. It seems they are focused on their proprietary Chrome app. As such, I merely assumed that app to be full-featured. Similarly, I have not seen how to create a watch-only wallet for import to Electrum from a given Ledger seed. Can you point me to a description for such? Ahhh. I retract my previous comments then. I think like everything else with electrum, it's pretty self explanetory and the software gives you a lot of information. It is quite strange that ledger would point you to that, as I see it, electrum probably works better. I found this topic which looks quite informative, it is from a few months ago so not sure how useful it is: https://bitcointalk.org/index.php?topic=1860569.0As a side note, it may currently be impossible to put it on electrum if you're using segwit addresses instead of legacy addresses. If you coins are in a legacy address you should find that it should work well. Once electrum is downloaded from electrum.org/#download all you need to do is run it, select "Use a Hardware Device" and it shoud search for your wallet. It shouldn't even need any authorisation from the ledger when you start it as all it needs is the unencrypted data - mainly the public key. If you do this it's useful to keep your chrome add-on just in case but eectrum proably has a lot more features (or is at least easier to handle as its open source and has at least 4 main developers - I think). |

So Electrum docs say to move your coins to a new wallet before splitting using the private keys of the old wallet. How do I do that? I've already created a new wallet. If I use a regular network transaction I have to pay fees. There has to be a way to do this from withing Electrum.
Don't sweep the coins. Just send a transaction using the max button and set the slider to be within 25 blocks if you don't need the coins quickly as it'll give you a good low fee to use instead. |

OK. Thank you very much. I will try another day with the 32 bits release.
By the way, it seems that now we can shut bitcoin core. I think it was a problem with older release.
My computer is an Intel i5, 3 years old. I think the performance problem is the disk access. 149Go is a lot of data.
Ah yes it might be a hard drive issue. If you want advice, you can try defragmenting the drive and you can use software already build into windows (if it is windows you're using). Just right click>properties>tools>defragment on the disk in windows explorer. |

If you post or pm me the unconfirmed txids in question I will push them for you and clear this up in a few hours.
Thanks BitcoinNewsMagazine. I truly appreciate the offer. But as by happenstance, both txs have now cleared. Interestingly, both in the same block. (?!) However, my questions remain. Is there a way to prevent nano s from doing this? What software were you using with the ledger? Thanks for your reply. The official Ledger Chrome app. If it was electrum
!?!?!? Why would I use Electrum!? I mean, I get that one can use the same seed for both. But putting it on an internet-connected computer seems insane to me. At least for substantial values. Which is what I am talking about here. then it's somewhere in the preferences there is a setting that says "spend unconfirmed outputs" that you need to uncheck.
If the second transaction fee was a regular fee or higher then they'll both get confirmed at the same time for the miner to get the most profits.
EDIT: it's in tools>preferences>and "spend only confirmed coins" should do the trick.
Cool. Yeah, I used Electrum to sweep my keys one-by-one from my previous Armory offline cold storage solution, and send them one-by-one to nano. Been using Electrum for trivial usages for years. I have that down. Any way to do coin control (or any of the other needs I enumerate above) in the native Ledger Chrome app? NO. I noticed lots of people use electrum. It creates a watching only wallet using the public key handed to it from ledger and creates a transaction in raw form that the ledger can then sign. I see no mention in your OP of using a Chrome app to do this and am unsure why you did not know you can do this in electrum. Or did you enjoy exposing your private keys to chrome already? (hint: that doesn't happen either). I mean I should've joined the dots there and realised that someone would buy a ledger to sweep its private keys stright into electrum. |

This is a fairly uselsee idea. You need to change addresses/wallets eiter before or after the fork.
If you send back the original address, the other client has your private keys and can still use them thus your coins can still be stolen (especially if the address has had a large amount in it before, they're more likey to want to wait for that same amount to reenter the address and quickly sweep it into theirs).

OK. I restore the release 13 and a backup of my wallet.
Everything is now OK.
I notice that I had the 32 bit release of the release 13 and I had installed the 64 bits release of the 15.0.1.
Do you think that can be my problem ?
Yes that can cause issues as the amount of memory (RAM) access is different between the two which can also effect other things. If your computer is not 64 bit then running a 64 bit will cause lag (if it runs at all). |

Are you suggesting I run a Core node on Linux because it offers coin control? I'm afraid I lack the resources and expertise for that. I can send BTC with the Ledger software wallet but it would mean sacrificing privacy (my main concern) and paying higher tx fees due to the lack of coin control (their software does not try to minimize tx inputs to reduce fees).
Is there any way I can get in on the testing of Electrum v3?
Follow tryninja's suggestion below. Just check you definitey have a backup of a seed and you double check everything your doing and you do download the first stable/complete version of electrum when it is released and supports segwit. Also, I was suggesting that you run bitcoin core without downloading any blocks (however I realise that may not work with segwit addresses now  ) Are you suggesting I run a Core node on Linux because it offers coin control?

You can actually build Electrum from the source yourself with the last commits, since AFAIK Segwit is already somehow usable. But I wouldn't recommend. Just follow the GitHub repo[1] README. [1] https://github.com/spesmilo/electrumIt has normally been tested before it's put on github as far as I am aware, however, I (like you) wouldn't necessarily recommend this is OP can wait a bit longer for it. |

They're probably just still testing it.
Without compromising the security of the device, unlessthere's another wallet that supports both ledger and segwit, you'll have to wait until electrum v3 comes out. For now your Bitcoins are safe. If you need to access them, you can always run live linux from a CD ROM and sign a transaction to send the funds back to yourself using your private key in bitcoin core but if possible, keep your private keys on your ledger wallet.

hard to get people to sign up when when pay out is 35 sat 😣. Other sites are paying 60 every 15 mins ( 240 sat an hour).
People will invest/gamble there more likely than they'll use the faucet. And if you get lottery and reward points then that's extra also. One more week to hope to be a lucky man on lottery  By the way, the reward point bonus of this week is awesome: x5 RPs  But I can't win the multi play after burning my account several times  How many tickets do you have? Is it from the free rolls that you've collected them or have you improved your odds. Also, at least the multiply has given you some lottery tickets even if some bitcoin has gone due to it. |

Not really, there are different internet backbones across different companies or conglomerates here . Claro is owned by Telmex and bought several companies when it arrived in the country . It bought Embratel and its backbone, a long distance operator and the first internet backbone in Brazil across the whole territory. Claro also bought NET , a HFC video service, but then a CMTS network was overlaid onto the HFC cable infrastructure, creating an internet access network to the end residential customer, something Embratel didn't have as a long-distance operator only. For instance, the IP phone service in my house is provided by Enbratel but the Gateway machine is physically ocated at Embratel headquarters. In addition there were backbones from other local government-owned telcos, now private businesses, like Telefonica in the state of São Paulo and Telemar at other 24 states. Then the international Optical cables arrived like Global Crossing ( now Layer3) , TIWS ( also Telefonica international) , 360 Networks etc. In the sequence the local backbones connected to the Optical cable companies international networks, so this is a 100 head hydra that never stops growing and interconnecting. This is a view of the last 15 years in Brasil ..I have some knowledge of the scenario, but very few interconnection engineers n these companies really know what peers to what and in which node and for what traffic etc etc ...
Ah, that sounds like quite a confusing system - i assume the confusion betwene tem has arisedfrom the multiple different companies tyring to connect everything as quickly as possible and giving everythiing enough internet. Aren't telefonica based in Spain as well? From where I'm from, there's one company that deals with connecting everyone to the internet (Openreach) which then allows ISPs to connect everyone to the internet. I've never heard of a country doing what yours does (although, it would make a nicer bit of competition betwen companies if we had more than one internet connection provider). Anyway, did you work out if it is a connection issue? It is possible to Ping bitfinex from the command line. I get this: C:\Users\Laptop>ping bitfinex.com -n 10 Pinging bitfinex.com [104.16.174.181] with 32 bytes of data: Reply from 104.16.174.181: bytes=32 time=19ms TTL=55 Reply from 104.16.174.181: bytes=32 time=19ms TTL=55 Reply from 104.16.174.181: bytes=32 time=19ms TTL=55 Reply from 104.16.174.181: bytes=32 time=19ms TTL=55 Reply from 104.16.174.181: bytes=32 time=20ms TTL=55 Reply from 104.16.174.181: bytes=32 time=24ms TTL=55 Reply from 104.16.174.181: bytes=32 time=21ms TTL=55 Reply from 104.16.174.181: bytes=32 time=19ms TTL=55 Reply from 104.16.174.181: bytes=32 time=19ms TTL=55 Reply from 104.16.174.181: bytes=32 time=26ms TTL=55 Ping statistics for 104.16.174.181: Packets: Sent = 10, Received = 10, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 19ms, Maximum = 26ms, Average = 20ms For me, normal is 19milliseconds though the internet is a bit slower due to a spike in the use of domestic internet. |

I did not do a violent shutdown. But I know that to reload the blockchain takes something like 15 days.
The log is in english... and very big.
Here is the first and last lines. It seems it freed memory, so for that it will be OK.
What I would like to know is :
- Is it normal ?
There deosn't seem to be anything in the log that is erroneous. - how long can it takes ?
The 15 days depends on how good your computer is, I assume it's a low spec as I have a low spec (old) one that's faster. - what happen it I shutdown the PC (I have electricity's cut where I live).
It'll probably restart, if you can get something lie a battery that it can use or keep safely shutting it down every 1000 blocks it might be OK. Sometimes, I shut mine down from the power button (so it doesn't safely shutdown) and 80% of the time it's fine, 20% it's corrupted... |

Creating a transaction requires approximately 10 bytes to start with. Then, each unspent output that you use as an input to fund the transaction adds approximately 149 bytes. Each new unspent output that you create (each recipient that you send to) adds 34 bytes.
So if we send to multiple addresses one by one, each additional address will add ~10 bytes? For example, if we pack 100 receiving addresses into one transaction, then we can save ~1000 bytes of space? Also, is there a limit for how large one transaction size can be (in bytes)? Or a limit of total receiving addresses we can include in one transaction? Yes you would save about 1000 bytes of space. And there is normally a mempool limit of 100KB and a maximum literal transaction size being 1MB. You could contact a mining company who will probably be happy to mine your transaction if it's bigger than 100KB but it'll cost quite a bit in TX fees (viabtc allow you to broadcast transactions so they will pick up the transaction if they set rules that means it doesn't have to be on the mempool in order to be accepted). There was a block a while back which waas mined by F2pool I think that contained a transaction 900+KB in size. |

I am sorry, I thougt it was in french. I don not know where to post it elsewhere.
I install the last release of bitcoin core, the 15.0.1. For the last 4 hours, it is on the first windows saying "rewinding the blocs". I try to stop it but I got the window saying I have to wait (if I stop it violently, it takes me 15 days to reload the blockchain). I do not know what to do.
Is this the first time you have done a violent shutdown on it and got to wait 15 days? In the folder where your blocks are stored, can you open a file called debug.log and paste it in here? Here's the French board: https://bitcointalk.org/index.php?board=13.0 they might be able to help you better (especially if the debug.log is in french) |

@hbou, il suffit de lire le français
Very few reading this in this section will be able to understand what you're saying, you might want to post this in your local board instead. I cannot work out what language you are using to be able to convert your post into English. EDIT AHA it's french! My Post Translated: Cela ne va pas être facile à comprendre, vous pourriez vouloir afficher ceci dans votre conseil local à la place.
Je ne peux pas déterminer quelle langue vous utilisez pour convertir votre anglais.
EDIT AHA c'est français!
Your post in English I installed version v0.15.0.1 and it is more than 4 hours that it displays the message "Rewinding blocks ...". I tried to stop it, and I get the window that says not to close until it's over. It consumes more and more memory and will end up planting anyway. If I stop the PC brutally, I left for 15 days of loading the blockchain ...
Can someone help me?
In response to this: The client needs to scan the whole blockchain, if you are after something that takes up much less memory then you can look for something like www.electrum.org/#download (An alternative to bitcoin core), otherwise, you'll just have to keep downloading the blockchain. Wait out the 15 days if you haven't already and repost your findings if you wish to continue using core. Translation: En réponse à ceci: Le client doit scanner toute la blockchain, si vous cherchez quelque chose qui occupe moins de mémoire, alors vous pouvez chercher quelque chose comme www.electrum.org/#download (une alternative au noyau bitcoin), sinon, vous aurez juste continuer à télécharger la blockchain. Attendez les 15 jours si vous ne l'avez pas déjà fait et postez vos résultats si vous souhaitez continuer à utiliser le noyau. |

BTW, you were right ! Bitfinex also uses Cloudflare ! I did some search and apparently this is the peering table for the recently activated CloudFlare POP in Rio de Janeiro. CloudFlare https://www.peeringdb.com/net/4224Looking above, the service provider peer available for corporate solutions ( not my case but anyway) is Equinix. Equinix has peering with local carrier & internet service provider Telemar /Oi , but not with Claro ( my cable internet provider) https://www.peeringdb.com/fac/1586So a quick conclusion is that I'd be better off connected to a Telemar/Oi access point and not a Claro access point. While Claro does peer with Telemar, being a Claro customer, I am clearly one hop further from the Cloudflare gateway locally. Not sure if that would make a big latency difference , but it was worth the conclusion. Thanks again. Don't you have the same cabling company throughout your country? I thought every country just had one company. Mine have a company that provides the Internet and multiple companies that can connect you and offer service. |

Just make sure that before you import your private keys into any other wallet to claim your new coins, that you send your bitcoins first to a new wallet (for which you will have new private keys then). That way your old private keys dont contain any Bitcoin anymore (only the new coins you want to claim), so the loss of loosing your BTC accidentally (maybe replay protection was not implemented) is reduced greatly.
I'm not sure this protects against replay protection but it does protect against things like keyloggers that could be strategically placed inside the wallet software. (Though it may offer some replay protection as well). |

Maybe an old 2FA key backup? Some sites use pretty long 2FA keys. It's an armory wallet backup. Who does it belong to?
Armory wallet root keys are 18 x 4 characters, lowercase, no numbers, which doesn't quite fit OP's description. From a bit of googling CoinDesk state multisig didn't come in until 2014 (presumably lots of people got hacked with the 2013 price spike, which, until recently was the highest we'd seen the price of bitcoin go). Also, i thought multisig gives there private keys, not one long one but i may be wrong on that. |

Hi
I am in Brazil, South America. My internet speed is 60 Mbps via HFC cable network, anything higher than this is useless ( here) as there are other bottlenecks up the network.
By "Exchanges" I mean buying/selling bitcoin online and not mining server pools working on blockchain confirmations. I am used to the console and the (speedtest.net) but, as you mentioned, there are other variables affecting the measurement, when done using the "common" ways to evaluate the roundtrip time, like DoS attack protection , and increasingly, I don't know what is considered "normal" or "acceptable" roundtrip times for working with buy/sell in exchanges. That's why I expected some service to show me where do I stand in regards to the "standard", maybe even from the Exchange itself would be the optimal case scenario. Thanks .
Since my post I had a thought. Since most of these exchange site (especially American ones) use cloudflare, it is your connection to that service that is the issue. However, if you mean there is a delay in buying your coins, maybe it has to go through your bank and gets stuck there (try using a debit card if you haven't already). Although, even after s debit card is used transactions can take up to 7 days (though most sites trust you'll pay them as they have your identity if not). If you're merely talking about transferring coins from one exchange to another then this is another reason as to the delay as they still have to wait for the transaction to be confirmed by a miner. |
