1342  Bitcoin / Bitcoin Discussion / Re: Can the delay in blockchain confirmation be one drawback of bitcoin transactions on: March 20, 2023, 01:18:50 PM
I was not worried because already the customer had shown me his device to check the network confirmation (from his end, it was showing about 15 network confirmation), but I never received payment.
I don't understand this. You say the transaction had 15 confirmations, but you never received the fund.
Do you mean the sender scammed you with displaying a fake image on his/her phone?

Although I did not keep the customer waiting because I am aware that this is how the network can sometimes be delayed, he did drop his phone line with me and ask me to notify him when i recives. The payment finally arrived in my wallet after a long time of waiting.
Take note that there is no guarantee that an unconfirmed transaction will be finally confirmed. You shouldn't accept unconfirmed transactions.

tisnaislam111 copy-pasted that from the post made by shasan.


But I don't think mods banned you without looking at closely. You must did something else that looked like a full plagiarism.
I don't understand Bengali and I used google-translator for checking the posts. It seems that tisnaislam111 copy-pasted shasan's post and just changed two dates and a number.

For the sync process, how long does it take to complete (100%) according to your experience.
Electrum is a SPV wallet which means that you don't have to download the full blockchain.
In electrum, you connect to a server and get only the transactions data of your own wallet, so that it can display your transactions history, the correct balance of your wallet and the list of your UTXOs.
If you have made/received many transactions before, it may take a few minutes. If you have never made any transaction, it would take a few seconds.
1345  Bitcoin / Electrum / Re: RBF adjust fee, choose adjusted output? on: March 18, 2023, 10:41:25 PM
So, the node you have connected to doesn't have your transaction in its mempool.
I think you should be able to broadcast a new transaction with desired fee rate. If the fee rate is higher than the fee rate used for the previous transaction, those nodes that have your previous transaction in their mempool should replace that with the new transaction.

A private key generates thousands of useful addresses where you can receive,
A single private key can't generate thousands of addresses. Any private key can generate a legacy address (an address starting with 1), a nested segwit address (an address starting with 3) and a native segwit address (an address starting with bc1).
Any private key can generate two legacy addresses if we consider both of compressed and uncompressed keys.

You probably confused private key with seed phrase. A seed phrase which is a series of words can generate numerous addresses.

it's in the addresses window but it's not in my receive window, how can I return it? and is there any chance I'll get my BTC back?
Due to privacy reasons, electrum generates a new address (which is one of the addresses shown in "Addresses" tab) every time you request an address. That's why that address is no longer shown in "Receive" tab.
This has nothing to do with the fund being stolen and unfortunately, there's nothing you can do. Bitcoin transactions are irreversible.

All the recent transactions made to 1DRJ3pkdSXTgYh59Rv7yUUQBErhTJ5rskB have used very big fees which shows that the one who made those transactions has been in too much of a hurry to get confirmation.
And given that all those transactions have been made using the same amount of fee, it doesn't seem that they have been made by a human.
It seems that your wallet was compromised or you used a fake version of electrum.

As mentioned above, you can easily recover your wallet using your seed phrase.
If you want to re-install your OS and you haven't already backed up your seed phrase, click on "Wallet" at top of the window and select "Seed".


Will the assets in my Electrum wallet be deleted too?
Take note that your bitcoin is on the blockchain, not in the electrum. No one can remove your bitcoin from the blockchain.
1353  Bitcoin / Bitcoin Technical Support / Re: Transferring a wallet from electrum (2fa) on: March 14, 2023, 07:45:19 AM
Yes, it wouldn't work because it's a 2FA segwit as Santorini7 said above but I already tested my method a long time ago to extracted a private key from my 2FA wallet. I don't know about the latest version of Electrum but I tested it a long time ago.
No version of electrum can give a single private key that can be used for recovering a multi-signature wallet. As already said, that's not possible that all.
Note that even if you disable 2FA, you would still have a multi-signature wallet.
1354  Bitcoin / Wallet software / Re: Coinomi wallet hacked, all funds stolen on: March 13, 2023, 07:47:25 PM
Do you think coinomi themselves stole these funds because it is closed source and they can get access to keys or anything ?
There is no way to know that. We don't know whether they have access to users keys or not.

The coinomi wallet is being used by so many people and they have a name in the market. They would not stole people funds, as if they do, they will have a bad reputation and people will stop using this wallet.
Being used by many people doesn't mean that's safe. Visit the following topic and see how a vulnerability caused a coinomi user to lose all his money.
WARNING - Coinomi Wallet CRITICAL Vulnerability Made Me Lose My Life Savings

I guess there may be fault at the OP end which made him lose all his money.
This is the most probable case.
1355  Bitcoin / Bitcoin Technical Support / Re: Transferring a wallet from electrum (2fa) on: March 13, 2023, 12:57:25 PM
The command you use importing the private key to bitcoin core is wrong you should remove this p2wsh: check the sample below

Code:
importprivkey 5KJvsn......
OP's electrum wallet is 2FA which is a 2 of 3 multi-signature wallet.
As mentioned above by o_e_l_e_o, it's not possible to generate such a wallet with a single private key at all.
For generating a 2 of 3 multi-signature address, you need three public keys and for spending fund, you need two of private keys.

And of course, bitcoin sent to such burn addresses is not provably burned, and could be recovered in the future. The amount of provably burned bitcoin is quite low at 2,823 BTC.
What do you mean they can be recovered in the future? how?
In theory, it's possible that someone has the private key of those addresses or someone will be able to brute-force the private key of such addresses and can spend the bitcoin sent to them. There is no proof that the bitcoin sent to those addresses will be never spent.
In practice, it's very unlikely that someone will be able to spend them.
1357  Other / Beginners & Help / Re: Hello bitcointalkers! Public and private keys/open and closed source wallet? on: March 12, 2023, 10:32:51 PM
but something I don't understand is that how can someone recover is private key if you didn't see it again please can someone explain it to me for more understanding
There is no way to recover your private key if you lose it. If your lose your private key, your fund is lost forever.
Take note that your private key isn't like a password in centralized services that you can set a new one if you lose it.
1358  Bitcoin / Wallet software / Re: What is BIP39 on: March 12, 2023, 10:17:35 PM
Backing up your modified wordlist is not mandatory, you just need to add the words belonging to your seed into the english.txt file, as explained above, to let Electrum accepting your own mnemonic seed.
But according to the post made by o_e_l_e_o before, you don't even need to add the words to your wordlist file.
I could generate a wallet successfully with the seed phrase posted by o_e_l_e_o  in that post, while I didn't have any of the words in my wordlist.
As you see in the following image, the next button is clickable.


1359  Other / Meta / Re: Does the forum system skip out on updating some user activities? on: March 12, 2023, 09:34:57 PM
Now the number of posts I have made totals 25, not including this post. Usually I don't have to wait long to balance the number of activities with the number of posts.
It seems like the forum system is working well regarding updates.
If I have correctly, you have been active in 5 two-week activity periods. This means that you can increase your activity up to 70 in the current activity period.
For increasing your activity to more than 70, you must have at least 1 post in one of the next actvity periods.
1360  Bitcoin / Development & Technical Discussion / Re: Can anyone help me to understand coinbase transaction ? on: March 12, 2023, 04:05:47 PM
how the coins are generated from air ?
That's how bitcoin is designed. Miners get newly generated coins as reward for their work.
Note that the coins generated on coinbase transactions don't come from thin air. Miners work for the newly generated coins.


are exchanges have another type of blockchain running?
What do you mean by running another type of blockchain? We have only one bitcoin blockchain.
