@oldurkey we don't have access to your wallet. Unless you answer the questions I posted above I can't help you.

If you don't know how to take a screenshot with your PC then take a picture using your phone camera of the electrum history tab and share that with us.
522  Bitcoin / Electrum / Re: Novice, but not a fool on: August 29, 2019, 11:44:38 PM
First of all I suggest you set the base unit to btc so that any confusion regarding unit of measurement is ended. You can do that via tools > preferences > general tab > base unit option. Then I ask that you post a screenshot of your history tab. You can take screenshots using the print screen key, upload it to imgur.com and share the link here.

I also ask that you tell us what it says for wallet type and script type under wallet menu > information.

Edit my best guess at the moment:


BTC0.0089 (original balance) - BTC0.0026 (your expenses) = around BTC0.0063 (fees not included) should be the current balance.

4.67278 mBTC is OP's remaining balance that is equivalent to BTC0.0047 therefore around BTC0.0016 is missing.

Can you analyze well each of your transaction in your history? It was just a small gap between your stated final balance and the supposed current balance. Maybe you missed something.

0.001 = 2fa fees for using a 2fa wallet. i'm guessing the balance is general bitcoin transaction fees. Once the OP answers my questions we'll know for sure if this is the case.

Does the one seed store 2 cosigners then? I have an empty 2fa wallet and assume one is the trusted coin xprv and 2 are generated from the seed mnemonic or am I completely wrong.

Yep 2 of the cosigners' xprvs are derived from the seed. There's a detailed explanation here: https://bitcoinelectrum.com/frequently-asked-questions/#how-does-a-2fa-wallet-work
524  Bitcoin / Electrum / Re: Electrum error: not enough Credit on: August 29, 2019, 07:24:50 PM
@jackg, what Abdussamad said is correct. When you create a 2fa wallet, you will get a seed that allows you to restore the wallet but he missed to say that you have to specify the type:

Quote
Restoring from seed
Even if TrustedCoin is compromised or taken offline, your coins are secure as long as you still have the seed of your wallet. Your seed contains two master private keys in a 2-of-3 security scheme. In addition, the third master public key can be derived from your seed, ensuring that your wallet addresses can be restored. In order to restore your wallet from seed, select “wallet with two factor authentication”, as this tells Electrum to use this special variety of seed for restoring your wallet.
http://docs.electrum.org/en/latest/2fa.html

This is no longer necessary since the seed mnemonic encodes the wallet type so as soon as you enter the seed mnemonic electrum will automatically detect it as a 2fa wallet.
525  Bitcoin / Electrum / Re: Electrum error: not enough Credit on: August 28, 2019, 11:36:31 PM
you can tell whether you have a 2fa wallet or not via wallet menu > information. wallet type listed there should be illuminating.

if it's a 2fa wallet then restoring from seed should give you the option to disable 2fa protection. then you won't have to pay trusted coin to cosign your transactions.

to restore from seed just go to file > new/restore, enter a unique filename, click next, choose i already have a seed and follow on-screen instructions for the rest. when asked whether you want to keep 2fa protection be sure to choose not to.
526  Bitcoin / Electrum / Re: Need help to send my btcs from electrum with no SEED and no 2FA on: August 25, 2019, 02:05:34 PM
Seed isn't stored in a 2fa wallet file so IDK what the OP did.

The only case where the seed is stored in the wallet file of a 2fa wallet is if the wallet has been restored from seed and the user chooses to disable 2fa protection at which point it ceases to be a 2fa wallet. But if that's the case it wouldn't prompt the OP for an OTP code when he tried to spend his coins. Yet he says he was prompted for it.

I don't have a full node. I wouldn't be using electrum if I did.

The original owner washed his hands of it years ago. He may have sold it to a scammer or he may have broken bad himself. It cannot be trusted.

Did you expect that the former owner of the website do anything different? He said he sold the website and cannot be responsible for it anymore

What did you expect? Like "ok, I sold my website but I can guarantee that the new owner is an honest guy and I am responsible for his actions"

If you sell your site to a scammer then you definitely bear some responsibility. You're setting people up to lose money. The only way to legitimately exit such a business is to sell it to someone you know is honest. Otherwise you don't sell it at all and yes that means you lose out on the gains but it is the right thing to do.

An example of the correct way to do things can be found in the sale of multibit software to keepkey. The multibit developers made sure to sell to a trusted entity in the space. When Keepkey found themselves incapable of maintaining the software they chose to shutdown the project rather than sell it to a malicious entity. They could have sold it and recovered the amount they spent on acquiring multibit but they chose doing the right thing over material gains. All in all no user lost funds and the reputations of all parties involved were maintained.

That's not how things work. And if you properly airgap your computer, the risks of using this website are very low (or non existent)

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.
529  Bitcoin / Development & Technical Discussion / Re: Using mouse input for extra entropy on: August 22, 2019, 04:36:51 PM
If the site is compromised it doesn't matter if you use it offline or online. The owner of the site could easily set it up to generate compromised private keys. Other users have complained about this site too. It  is not safe.

Do you know how much people have complained about electrum already ? Countless..
Do you regard electrum as not being safe too ?

I do not agree with any kind of paper wallet creation through websites (regardless whether online or offline). But without proper evidence, or at least some indications, calling a random paper wallet website not safe is not completely correct.
No website is safe for newbies. No web wallet is. And no desktop wallet is.
Nothing is safe for a user without common sense. Not even a hardware wallet.

Are there any indications why this website should be avoided (besides newbies complaining about it) ?

The original owner washed his hands of it years ago. He may have sold it to a scammer or he may have broken bad himself. It cannot be trusted.

Coins sent to this address have all been spent: https://www.blockchain.com/btc/address/1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3

Except for the genesis block other early block's rewards can be spent.

edit: I restored a wallet using these two addresses 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa and the 1Q one given above. The result is  a transaction history going back to 2011 only.

No site is safe for newbies. You should always use a hardware wallet if you are a newbie.

It was his fault.

I generated my bitcoin paper wallet on in January, 2019. I did it online in my browser and didn’t follow through all the recommendations at 

That guuy didn't follow recommendations and is now crying that he was hacked....

There are wallets doing that already.
Like this one

bitcoin paper wallet

You move your mouse until you make the necessary entropy. You can use your keyboard as well with your mouse movements. After that, your private key is generated.

However, I read somewhere that humans are not good sources of entropy.... so maybe that is not a good idea. We problably keep moving the mouse in some crazy pattern.

533  Bitcoin / Electrum / Re: hi anyone can help me? i use electrum wallet on: August 21, 2019, 09:24:21 AM
electrum doesn't use bip44. op hasn't replied so we are just going around in circles here Tongue
534  Bitcoin / Electrum / Re: hi anyone can help me? i use electrum wallet on: August 20, 2019, 03:59:51 PM
Zen cart people won't be able to help. I suggest the OP provide us with the address where the funds were sent, confirm that the address is a part of his wallet (how to do that?), tell us his electrum version and the information for wallet type and script type under wallet menu > information. It wouldn't hurt if he also provided us a link to the exact zencart payment plugin he used.

If the transaction is confirmed on a blockchain explorer (for example, blockchain.info), it's likely an issue with your electrum wallet. Make sure you check the address so it's the same as the electrum one, and you should either restart your wallet, or re-sync it. If this still doesn't work, import the seed into another wallet (mycelium for mobile works).

Checking the address on a block explorer is a good idea but electrum seeds can't be used with other wallets.

You can request the feature on github issues: https://github.com/spesmilo/electrum/issues . I for one think it is a valid use case for rbf transactions.

I thought you could just delete it from your local history and then make a new transaction to broadcast?

I've normally done it with an intention to double spend it straight afterwards so I've had 2 computers and signed it on both... But it's probably helpful for when you get the address wrong.

So you're talking about deleting the transaction from the wallet file manually and then using coin control to spend the specific outputs? There's no easy way to do it via the gui which is what would make it accessible to a larger audience.

537  Bitcoin / Electrum / Re: Were my bitcoins stolen? on: August 18, 2019, 03:17:57 AM
Also boggles my mind and how the hacker does know the exact time on where the funds is being credited into his electrum? Supposedly this is an old version and
he shouldnt able to connect to any server.If he do upgrade only thru electrum.org directly on 3.3.8 then the question how those funds instantly robbed?
This is definitely a malware issue.

His wallet secrets must have been stolen. That is the private keys and or seed. The thief then simply watched the blockchain for funds sent to this wallet and swept them as soon he could. This would have been automated for maximum efficiency Smiley

It would still be interesting to learn how his wallet secrets were stolen. Other software installed on the same system is one possibility. The user himself revealing the secrets by entering them into a phishing website is another. It's also possible he installed a fake version of electrum.

539  Other / Beginners & Help / Re: what's the use of 1000+ cryptocurrencies? on: August 14, 2019, 12:23:49 AM
There is no use. 99% of them were created so their owners can get rich and 99% them will die in the long term. Either they don't need to exist, or they don't work, or they are just a bunch of buzz words and promises.

Stick with the big coins with real-world use unless you want to gamble in the market.
That's a bit shocking, can't understand how 99% of them have no use XD explain more, please.

edit: maybe I got fascinated by the buzz words and promises XD

If you could print money wouldn't you? That's why there are so many. You spend some money roping people in to your newly minted cryptocurrency, getting the price pumping and then dump it on them. That's why they make them.

Stick with bitcoin only. Not bitcoin cash or some other pretender.
540  Bitcoin / Electrum / Re: 3.3.8 not connecting since days? on: August 13, 2019, 02:39:32 PM
I'm glad I finally fixed this with all you guys' help, but why would electrum try to prioritize and connect via a vmware network adapter instead of just the normal ethernet?

It depends on the routing table of your operating system.

To all the regulars here I'd like to point out that Electrum now has a debug log option under tools > preferences  > general tab. In future in situations like these please advise users to turn that on and pastebin the log files. They can found in the electrum data dir.
