1941  Bitcoin / Bitcoin Technical Support / Re: unconfirmed transaction....need help on: November 17, 2022, 10:58:53 AM
I am not sure if it ever gets confirmed.
The mempool is becoming less crowded and as mentioned by NeuroticFish, your transaction will be probably confirmed.
Two days ago, there were around 150 vMB of transactions in the mempool and now the mempool size has decreased to around 60 vMB.
It's very unlikely that your transaction remains unconfirmed and dropped from mempool of nodes.
1942  Bitcoin / Bitcoin Technical Support / Re: unconfirmed transaction....need help on: November 17, 2022, 08:55:57 AM
Usually the fee is adjusted automatically, depending on the amount of transaction and has always worked.
This is wrong.
The amount of fee required to be paid for a transaction has nothing to do with the amount of bitcoin you send.
The transaction fee depends on number of inputs and outputs, your address(es) type, the network state and how fast you want your transaction to be confirmed.

It's impossible to say when your transaction will be confirmed, but I expect it to be confirmed in the weekends.
1943  Bitcoin / Electrum / Re: is it Safe using console to generate seed? on: November 17, 2022, 12:02:31 AM
Isn't that generating a seed on Electrum through commands will work in the offline machine?
Right. You don't need internet connection for that.


Or needs internet because the command will send to servers/any nodes.
Servers have no role in generating the seed phrase.
  

Just want to confirm currently I have a broken PC can't confirm it but if it's allowed to generate seed offline through command then this is the safer one.
Whether you want to generate the seed phrase through GUI or console, you can do that offline and it's not that generating the seed phrase using commands is safer.
1944  Bitcoin / Bitcoin Technical Support / Re: How do i make sure my Bitcoin Private Key is Random and secure? on: November 16, 2022, 10:24:19 PM
One last question. Is it more secure to generate a 24 word seed using dice/coins (manually) OR using CSPRNG present is software like electrum etc ?  Which is more secure?
In both cases the seed phrase is generated completely randomly (assuming your dice is balanced and all the numbers have the same probability to be chosen) and is secure enough.
It may worth mentioning that, if you want 100% security, you should generate your seed phrase on an air-gapped device.
1945  Bitcoin / Wallet software / Re: What wallet should i choose are my steps correct? on: November 16, 2022, 10:01:52 PM
What i meant is that if we have 24 words private key (seed) it has to read up it from somewhere to give access to our BTC seed ETH seed etc. and the question is where do it get it from?
It's not that there's a centralized server keeping all addresses, private keys and seed phrases.
Your private keys are derived from your seed phrase through some mathematical calculations locally in your device and you sign the transaction using your private key without any need to being online.
1946  Bitcoin / Bitcoin Technical Support / Re: How do i make sure my Bitcoin Private Key is Random and secure? on: November 16, 2022, 09:41:23 PM
Regarding your answer to second question. I was not saying i am using brain wallet. Please read again.
I fully understood you.

I meant i generate a bitcoin private key using secure wallet say for example mycellium wallet which is completely random key BUT the private key that i got now is 100% a SHA256 hash of some random 'text'. so that text might be a 'word' from the dictionary. There's a chance for that. This is what i meant to ask.
There's a chance of that, but that's almost impossible.
If you know that any bitcoin address can be generated by 2^96 private keys on average, you may worry even more. But as I said in my previous post, a bitcoin private key provides enough security and there's nothing to worry about.
1947  Bitcoin / Bitcoin Technical Support / Re: How do i make sure my Bitcoin Private Key is Random and secure? on: November 16, 2022, 07:52:05 PM
1.)I checked the electrum code and it also uses RNG that just picks a random number between 1 and 2^256 so therotically RNG can a pick a 10 digit number too? or am i missing something here?
That's true only in theory. The probability of getting a 10 digit number is almost zero.


2.) Second question i have is. We all know how SHA256 can be used to convert any 'text' to a hash which is a valid private key right a.k.a brain wallets.
It's not recommended to use brain wallets. It's recommended to generate a random private key.


So my question is what if my wallet generate a key which is secure but what if that key is SHA256 hash of some 'poor dictionary word'?
No. There is no risk. What you worry about can happen only in theory. A private key generated properly provides enough security.
1948  Bitcoin / Mining / Re: Cloud mining for bitcoin on: November 16, 2022, 06:14:12 PM
There is no bitcoin mining website and all so called cloud mining websites are scam. Such websites usually display a fake number as your balance and once you reach their minimum withdrawal amount, they ask you to deposit some bitcoin to be able to make withdrawal.

Don't waste your time and your money. That's not how bitcoin is mined.
1949  Bitcoin / Bitcoin Technical Support / Re: How do i make sure my Bitcoin Private Key is Random and secure? on: November 16, 2022, 05:57:06 PM
So i know bitcoin private key is secure and there are 2^256 private keys
Number of valid private keys is slightly less than 2256


it's impossible for 2 people to generate the same btc private key.
Not completely impossible. Almost impossible and very very unlikely.


BUT what i think is possible is a bitcoin wallet generating a bitcoin address whose private key is in the range of 1 to say 10000?? then it's vulnerable to attack right?
Yes, that's possible if the wallet hasn't been coded properly and that's why you should use always an open-source wallet to know how the keys are generated.


See basically a private key is an integer between 1 and 2^256 converted to hex right.
That's between 1 and FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140

Will help forum users get more exposure to their services or products in marketplace.
Since scams are not moderated and some users may wrongly think that services with pinned topics are secure, I don't agree with the idea.


And will also increase the overall revenue of the forum which will help for more efficient management.
The forum doesn't need any money.
Theymos has even disabled advertising banners. See the following post.

Finally, bitcointalk.org has a large reserve of BTC, so we're able to continue operating without ad revenue for many years.


You can buy ads,
That's no longer possible.
1951  Bitcoin / Mining / Re: lowest hashrate that hit a block in the last 3 years on: November 16, 2022, 09:51:40 AM
Since we can only estimate the hash power of some mining pools and there are many unknown miners with unknown hash rate, it's impossible to answer to your question.
It's possible that a solo miner has found a block with a very low hash power, but we can't know how much hash rate is owned by any of individual miners.
1952  Other / Meta / Re: To comment/post removers on: November 16, 2022, 01:22:35 AM
archive.org used to take daily and then weekly snapshots of the forum's pages. Now I think it only does it every few months.
Doesn't archive.org (and other archiving websites) archive a webpage only if someone requests that? As far as I know, they don't take snapshot regularly.
It's possible that a webpage has been archived more than 100 times while another webpage has been never archived.
1953  Bitcoin / Bitcoin Discussion / Re: Mempool if full, but what does that actually mean? on: November 16, 2022, 12:46:02 AM
Right now we are at  354 MB / 300 MB,
I wonder where you got the 354 MB from. That's wrong.
Currently, there are around 150 MB of transactions waiting for confirmation in the mempool and even a transaction paying only 1 sat/vbyte should be able to enter the mempool of any node.
1954  Bitcoin / Electrum / Re: is it Safe using console to generate seed? on: November 15, 2022, 03:09:55 PM
As mentioned by Abdussamad above, it's only the command that is recorded. The output isn't recorded.
You can simply open your wallet file using a text editor application and check what has been recorded. You will see your used commands under "qt-console-history" and you won't see the outputs.
1955  Bitcoin / Electrum / Re: Electrum 4.3.2 - Two-factor authentication that has never been set up (no seed) on: November 13, 2022, 11:22:02 AM
I open the wallet using the password, I can see everything, everything seems to work, but when I want to send a payment the wallet asks for 2FA. Which really wasn't happening before.
Are you saying that you have made transaction from the same wallet without entering 2FA code before?
As I already said in my previous post, this is impossible. The wallet has been 2FA since the creation date.


Anyway, there is no icon in the wallet to show the seed like I see on someone else's.
That's normal.
If it was possible to export the seed phrase of a 2FA wallet, that would defeat the purpose of 2FA.
1956  Bitcoin / Electrum / Re: Electrum 4.3.2 - Two-factor authentication that has never been set up (no seed) on: November 13, 2022, 09:10:09 AM
It's impossible that a standard wallet turns into a 2FA wallet.
My guess is that you have created a 2FA wallet before and now you are opening a wrong wallet. Click on "File" at top of the window and then select "Open" to check if you have any other wallet.
1957  Bitcoin / Wallet software / Re: What do you think about trust wallet? on: November 13, 2022, 07:51:24 AM
So if something happens with trust wallet company and their apps become inaccessible then how i will be able to retrieve my btc,dot and other blockchain assets by using that one multi wallet mnemonic phase?
The seed phrase (also called mnemonic) generated by trustwallet is BIP39 and can be imported into many other wallets as well. Of course, this doesn't mean trustwallet is secure. Trustwallet is close source and we don't know whether they have access to users keys or not. It's also possible that you can't recover some of your altcoins due to not knowing the derivation path used by trustwallet.

The best is to avoid any close source wallet like trustwallet.
1958  Bitcoin / Bitcoin Technical Support / Re: mass generation of addresses using private key on: November 12, 2022, 04:24:11 PM
Uncompressed 3... from a private key? AFAIK it's impossible.
You are right. That's not possible.
When it comes to legacy addresses, there are two legacy addresses derived from a single private key. One is derived from the uncompressed private key and the other one is derived from the compressed private key. But there's only one nested segwit address and that's derived using the compressed private key.

1960  Bitcoin / Bitcoin Technical Support / Re: Bitcoin private key with 98 characters and starting with 3 on: November 11, 2022, 05:34:30 PM
I recently stumbled across a private key with 98 characters that starts with "3".
Are you sure that's a bitcoin private key? Maybe, it's an altcoin private key.


As far as I know, bitcoin private keys only starts with 5, K or L and is 51 and 52 characters long.
A private key starting with 5, K and L and including 51 or 52 characters is a WIF private key. That's the most common format of a bitcoin private key.
A private key can have other formats as well. For example, a private key can be in hexadecimal format and includes 64 characters (0-9 and A-F) or it can be a mini private key and includes only 22 or 30 characters.
