501  Bitcoin / Bitcoin Technical Support / Re: Help me to recover funds from 18 phrases on: September 25, 2019, 06:50:24 PM
OP's problem is simply that he can't receive emails by blockchain.info. It's not really a bitcoin problem it's an email hosting problem. I don't think we can help him here.

He can not receive e-mails because of the reason posted by hugeblack, his old account does not currently exist because blockchain.info/com is made changes that were clearly affected to all old accounts. Obviously the OP has no seed, but he and anyone else should get some info on how to recover such wallet. Is it possible for a service like blockchain to do this kind of nonsense and wipe-out all accounts in the process of site upgrades?

This is not e-mail hosting problem, users report the same issue with different email providers - they do not block anything, a verification e-mail is just wasn't even sent.



what makes you think the wallet doesn't exist? nowhere does he say that. he says he can't receive the email authorizing his browser to login to the account. this is an added security measure blockchain.info has.

old blockchain.info wallets were what are known as jbok ones - just a bunch of keys. These are unconnected random private keys unlike the deterministic wallets we use today. The recovery phrase is actually a password reminder phrase. It is not the seed.

The way blockchain.info wallets work is that the keys are generated in your browser, you set a password to encrypt them and then the encrypted copy is hosted on bc.i's servers. When you login the wallet in encrypted wallet question is downloaded from bc.i and decrypted using your password within your browser. The part he's getting stuck on is downloading the encrypted wallet. bc.i will not serve that file to him until he approves the login via his email account.

@OP another thing you can do is look for old bc.i emails in your email archive. They used to let you backup the wallet file. They sent them as .aes.json attachment files. If you have that you can simply drag and drop it to create a new wallet:

The onnly problem is that i am able to receive my authorization email to verify the wallet from "no-reply@blockchain.info". Is there somewaay to retrieve my wallet ?
Many of the old accounts have been closed or have not been added when the wallet update the interface so you will not be able to access your wallet using your old ID and password.
I remember that I did it with Blockchain.info HD wallet. They sent a message with ID after selecting the 12-word recovery option.
What happens after you enter the words on ---> https://login.blockchain.com/wallet/forgot-password? You should get a new account associated with those words (18 words.)

check your words here ---> https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

So half the replies in this thread are by people like this who haven't understood what the OP's problem is. He doesn't have an HD wallet. He has an old random unconnected private keys bc.i wallet and the recovery phrase is just used to recover the password. It is not the seed to the whole wallet.

OP's problem is simply that he can't receive emails by blockchain.info. It's not really a bitcoin problem it's an email hosting problem. I don't think we can help him here.
503  Bitcoin / Electrum / Re: Help accessing coins in old Electrum wallet on: September 18, 2019, 01:14:22 PM
SourPatch, you have two option to get access to your coins. First is to just download the latest version of Electrum (be sure that you are using only: https://electrum.org/#home ) for your OS. Then just install that new version, and you will have an updated version of Electrum, your coins will be there when you open a wallet and type your password.

The second option is to uninstall old wallet and then install a new one, but in that case, you need to have your seed (12 words) to recover the wallet. You need to select the option "I already have seed" in the process of creating wallet.

I recommend you try the first option, but before anything be sure that you have seed words. You can check them by clicking on tab "Wallets" and select "Seed".

uninstalling doesn't remove the wallet files.
504  Bitcoin / Bitcoin Technical Support / Re: How do i get to the screen to enter my seed on: September 13, 2019, 09:03:50 PM
Something that nobody has told: for Electrum, if you don't know the password, the UI doesn't let you do much else than simply close.
If you are in this situation with Electrum and don't know the password, but clearly know the seed, find the data folder of Electrum (it's called electrum_data) and (when Electrum is not running) rename it to electrum_data_old. Then start Electrum again and tell "I already have a seed" in the 3rd window.

That's not true. You can simply change the wallet filename in that opening screen and it'll let you create a new wallet. That can be a restored wallet or one with a brand new seed. It basically takes you through the whole wallet creation process all over again.

Electrum supports unlimited wallets each in their own file.
505  Bitcoin / Bitcoin Technical Support / Re: Old blocks changed on: September 11, 2019, 10:39:01 PM
manually compare the hashes of the old and new files. sha256sum them for instance. the reason being that timestamp changes can also trigger rsync. from the man page:

Quote
Rsync  finds  files  that  need to be transferred using a "quick check" algorithm (by default) that looks for files that have changed in size or in last-modified time.

if the hashes are the same then that means the file contents haven't changed and only the timestamp has been changed. then see if there's an rsync option that lets you ignore file timestamps and only compare file hashes.
506  Bitcoin / Electrum / Re: Transaction output in preview on: September 11, 2019, 08:04:06 PM
btw you should update electrum to 3.3.8 via electrum.org. 3.3.3 is an old version that is not safe to use.
507  Bitcoin / Electrum / Re: Transaction output in preview on: September 11, 2019, 08:03:23 PM
At the risk of sounding like a newb, I'm going to ask this for all those being careful with electrum due to the phishing scare.

When previewing my transaction, there are two output addresses and only one of them is the address I'd like my BTC to go to. Is this how it should look? Currently trying to send BTC out of my Electrum wallet to an exchange.

Thanks. And thanks for answering if this total newb talk.  Huh

yes if the other output address is highlighted in yellow or green.  that's the change address and it belongs to your own wallet.
508  Bitcoin / Electrum / Re: Ledger Device displaying Warning! When trying to confirm transaction? on: September 10, 2019, 03:56:40 PM
It's not a big deal so I would go ahead and confirm it. The change address is still derived from your seed so you control it. It's just different from what ledger expected.

edit: actually it's because you disabled change addresses in electrum preferences. if you enable them the warning goes away:

509  Bitcoin / Electrum / Re: Electrum 3.3.5 on a 32-bit Computer on: September 10, 2019, 01:25:02 PM
Ok so the problem is that the files in that folder are owned by root and not by the richard user. That's why when you run electrum as richard it fails to access those files. Please don't apply 770 permissions to ~/.electrum. Instead do this:

Code:
sudo chown -R richard:richard /home/richard/.electrum

That should make you the owner of the files. Then you can run electrum as an unprivileged user i.e. richard and not root.

510  Bitcoin / Electrum / Re: Electrum 3.3.5 on a 32-bit Computer on: September 09, 2019, 02:15:45 PM
You shouldn't be running electrum as root.

i suggest you post the output of the following command:

Code:
ls -lha ~/.electrum/
511  Bitcoin / Electrum / Re: Electrum Multi-Sig with Hardware Wallets - Problem on: September 03, 2019, 08:55:39 AM
Electrum can generate a seed by itself. It's a software wallet. So why not use a combination of electrum generated seed and a hardware wallet?

Hardware wallets are nowhere as important as people make them out to be. IDK why people spend so much money on them. You are essentially trusting the postal system and some remote company not to steal from you.
512  Bitcoin / Electrum / Re: Help with electrum receving address on: September 03, 2019, 08:50:53 AM

Humans are not a good source of entropy so what you've done is set yourself up to be robbed in the future. I also don't recommend generating a seed from any website out there.
I think you missed to read one of my last post. I did not use any seed from that website. I figured that just by typing random words and make a seed it works. You then use that random seed with recover wallet.


I did read that and that's why I said "Humans are not a good source of entropy". You may think its random enough but it's not.
513  Bitcoin / Electrum / Re: Help with electrum receving address on: September 02, 2019, 05:23:40 AM
Yes, I meant this.
But out of curiosity I just did this.

Create new wallet
Standard wallet
I already have a seed
I typed some random words and checked BIP39
p2sh-segwit (p2wpkh-p2sh)

I got Nested Segwit wallet.

My question now is that why do I need to generate seed using https://iancoleman.io/bip39



Humans are not a good source of entropy so what you've done is set yourself up to be robbed in the future. I also don't recommend generating a seed from any website out there.

I suggest you create a normal legacy wallet in electrum and use that. Let electrum generate a suitable seed for you.

I wrote that guide on bitcoinelectrum.com and it clearly says it's not for newbies. It also doesn't tell you to use any website to generate the seed because that advice is totally wrong. If you want to follow the guide then follow the guide. Don't go mixing and matching things from different sources without understanding the implications of it.
514  Bitcoin / Development & Technical Discussion / Re: Using mouse input for extra entropy on: September 02, 2019, 05:11:45 AM
No, you are mistaken. If the site is malicious it could be programmed to generate private keys known to the site owner. In that case it doesn't need network connectivity to compromise wallets so using it offline doesn't make a damn bit of difference.

Well, until you have some evidence that this is happening, you can't condemn the website.

You showed me a link of a newbie that lost hia funds because he didn't take any precaution and didn't follow website recommendations.

515  Bitcoin / Electrum / Re: Electrum and Ledger Nano S - BTC legacy addresses on: September 02, 2019, 03:27:09 AM
- Your ledger wallet has unlimited addresses. You could spend your entire life deriving addresses and not make a dent.

- No one knows about a particular address unless you told them about it and asked them to send money to it.

- If you're using ledger with electrum then it'll only care about the particular HD account and script type you told it to use during the wallet setup. p2sh-segwit, p2pkh (legacy), p2wpkh are all different script types. So unless you create a legacy script type wallet it won't know about it.

516  Bitcoin / Electrum / Re: Help with electrum receving address on: September 01, 2019, 07:38:06 AM
when I try to withdraw, he tells me that the address is not correct, what should I do?

You probably have an address starting with bc1, don't you? Unfortunately, many services still don't support this kind of addresses even though users would benefit from lower fees. You can either create a new wallet and select Legacy type of wallet or follow this guide in order to generate addresses starting with 3. You will save a little bit on fees if you do the latter one. If you don't mind it and don't want to mess up anything, do the former one.

That is not for newbies. Let him create a legacy p2pkh wallet instead or use some other wallet software that offers p2sh segwit wallets without having to resort to hacks.
517  Bitcoin / Electrum / Re: How to import 2-of-3 multi-sig keys to Electrum wallet? on: September 01, 2019, 01:13:53 AM
It's open source software coded by volunteers and given away for free. If you want to speed things up offer a bounty to the developers or code it yourself.
518  Bitcoin / Electrum / Re: Novice, but not a fool on: August 31, 2019, 02:10:29 AM
Darn it, I wish I could post what  some are asking for, but I'm in the dark. If you'll at least tell me what to click in order to post photos, I'll take shots of as many variations of the wallet as possible.

It doesn't matter anymore. We don't need screenshots now.

What has happened is that the exchange rate of bitcoin/usd changed and that is why the value of your balance in USD terms has gone down. On the 27th of june when you withdrew money from Bovada it was near it's peak trading in the range of $12700-13300. So 0.0071 bitcoin was worth $91.50 at that time. However since then the price of bitcoin has fallen and currently it's around $9600 per bitcoin. So that's why your balance is worth less in USD terms.
