It is quite new to me that it is 134 bits on electrum, I only thought what is different about the seed phrase between Electrum and BIP39 is how they are generated, inclusion of version number to Electrum seed phrase during generation, I do not know if the entropy is not the same.
132 bits of entropy, not 134. In a seed generated by electrum, there is no checksum. So, unlike a 12 word BIP39 seed phrase (in which the last 4 bits are checksum) in a 12 word electrum seed phrase, all 132 bits are generated randomly. For more information, click here and read the post made by o_e_l_e_o in response to my question on another thread .

Hackers take the advantages of the mistakes made by people. If your seed phrase is generated on an air-gapped computer, there's nothing a hacker can do. As stated by DaveF, a 12-word seed phrase provides enough entropy. Anyway, if you want your seed phrase to have more words for any reason, you can ask electrum to generate a 24 word seed phrase. (As humans may not be good at generating random words, I think that's a better option.) To do so, go to console and use the following command.
The 12 words are 128 bits of entropy, which is considered more then enough.
A 12 word seed phrase generated by electrum provides 132 bits of entropy.

I have been using Bitcoin Core because unfortunately I have some Bitcoin in my Armory wallet and would love to get Armory up and running so I can get my bitcoin out of there and not have to use Armory anymore.
You don't have to use Armory. As suggested by LoyceV, you can use a SPV wallet like electrum to access your fund. In a SPV wallet, you don't have to download the blockchain. In order to access the fund using electrum, you must export your private key(s) from Armory. To do so, follow the guide provided by HCP. (Click here) In electrum, create a new wallet, select "Import bitcoin addresses or private keys" and then enter your private keys. Warning:
Download electrum only from its official website and do not forget to verify your download.

My friend thanks for answering, so I have tried several times noreply@freebitco.in twice and I have asked for the forgot my password several times too, and I do not receive the email either in the inbox or spam. Is there anything I can do? or is there anything can help me please? I receive emails from noreply@freebitco.in without any problem. So, the problem should be on your side. Did you add noreply@freebitco.in to your contacts list as suggested by TheQuin? The other thing that comes to my mind is that you may have blocked the email address in question mistakenly. Go to "Security and Privacy" and check blocked addresses.

Imo, there should be no difference in penalties between source and non-source merit when they get caught selling merit.
If a merit source sells merit and that's proven, theymos will surely remove the source merits and that's why that message is displayed for merit sources. If a non-merit source sells merit, I don't think theymos takes any action. So, that message isn't needed to be displayed. (The merit abuser will only get negative feedback from other users).

You can’t proceed the transactions with a lower fees, error will appear.
Your transaction may not enter the mempool if the gas price is set too low. This means that the transaction is not broadcast at all and you have to use a higher gas price. Not being broadcast and getting an error due to that is different from being failed. Gas price in ethereum is something like fee rate in bitcoin. If the gas price is set too low, the transaction may not be broadcast at all and even if it is broadcast, it will take a very long time to be confirmed. But it won't fail. I know a transaction can fail due to different reasons. But a transaction doesn't fail due to low gas price.

they should cancel transactions with too little gas after a reasonable time,
What do you mean by "They"? Who are you referring to? Ethereum is decentralized (at least it is claimed to be) and no one has control over transactions. So, there is no one who can cancel the transactions. If you want an unconfirmed transaction to be removed from the mempool, the only way is to replace it with another one. Note that this can be done only by the sender. Even if you replace the transaction, you still have to pay the transaction fee. You pay for the replacing transaction instead.

If you enter the 12th word randomly, it's very very unlikely that the seed phrase is valid. As stated by bitmover above, even if the seed phrase is BIP39, it must pass the checksum. But you can still generate a wallet even with a non-standard seed phrase.
If you want to force electrum to generate a wallet with any words, click "options" and check "BIP39 seed".
If the seed phrase passes the checksum, electrum displays a message saying the checksum is OK. If the seed phrase doesn't pass the checksum, but all the words are included in the BIP39 wordlist, electrum displays a message saying the checksum is failed. If the seed phrase includes words that don't belong to BIP39 wordlist, electrum displays a message saying "Unknown wordlist".
In all three cases, you can generate a wallet.
Note that it's not recommended to generate a wallet using a non-standard seed. You should either use a seed generated by electrum or a standard BIP39 seed (a BIP39 seed that passes the checksum).

I don’t know why your transaction canceled even after paid such amount of gas fee.
Transactions aren't cancelled automatically. If you use a very low gas price and the network is so busy, your transaction may stay pending for months. But it's not cancelled. OP has definitely cancelled the transaction (replaced it with another one) himself.

Clearly, with a failed transaction, ~ $60 worth of ETH would just go waste🗑
Why should the transaction fail? Even if you set the gas price to 1 Gwei, the transaction will never fail, unless you set the gas limit to lower than the required amount. In the case the network is so busy and you use a low gas price, your transaction will take long time to be confirmed. It may take months, but it won't fail.

I am sure and sure to have a bitcoin core account after I no longer have my credentials, apparently I have it in my bone !!!
So the seed phrase you had written down belongs to another wallet. Even if you manage to find that seed phrase, it won't help you to recover your fund in bitcoin core. As already said, bitcoin core doesn't support seed phrase at all. Also, you have no chance to recover your fund using your email address.

we can not recover his account with his email address and private secretary questions
Are you sure you are talking about a bitcoin core wallet? You don't use any email address when creating a wallet in bitcoin core at all and there is no prviate question. If you used an email address for creating the wallet, it should be a custodial service like an exchange.
|

Bitcoin core doesn't support seed phrase at all. So, don't waste your time finding a seed phrase. For recovering your bitcoin, you must either have the wallet.dat file (+ password if that's encrypted) or your private key(s). Otherwise, there's nothing you can do.

Sorry man, OP is about to withdraw from a casino, and it's almost the same condition to withdraw from an exchange. And to proceed for withdrawals in those platforms, it's not possible to set the fee parameters.
You are right. The user has no control over gas price and gas limit when withdrawing from an exchange, casino or any other custodial service. The gas limit and gas price were selected by the casino as you truly mentioned, the transaction failed due to the low gas limit. In your previous post, you said that we shouldn't withdraw via ethereum network. I was saying that the transaction failure wasn't due to a problem in ethereum network. It was due to a human error made by the casino. The transaction failed because the casino used a low gas limit. Even if the network wasn't busy and the required gas price was 1 Gwei, this transaction would still fail.

This is a major problem why we shouldn't withdraw using Ethereum blockchain. With the huge volatility, it's hard to determine the right gaz fee especially within exchanges...........
It's true that ethereum network is busy and the transaction fee is very high. But that's not why OP's transaction failed. The sender used a low gas limit and that's why the transaction failed. Even if the mempool was completely empty, this transaction would fail. When you make a ethereum transaction, you need to set two parameters. 1. Gas limit 2. Gas price. If the gas limit is less than the required amount, the transaction will fail even if the mempool is completely empty and the gas price is very high. (This is what happened to OP's transaction) If the gas price is less than the required amount, the transaction will take a long time to be confirmed. But it will be finally confirmed.

I usually go with seed phrase for HD wallet. Never gave a try until yesterday with a single private key. Now it sounds like a lot of work to do with Electrum for a single private key.
That's very easy if the wallet is not multi-signature. You only need to add a prefix to specify the address type. When dealing with a multi-signature address, it's not possible to create it using a single private key even with a lot of work. Consider x of y. You basically need x master private keys to send any coin from the wallet.
You need x master private keys and (x-y) master public keys.
|
|
|
Now if you want to backup all of your private keys then a single master private key or seed should be enough to handle all private keys from your wallet.
OP is talking about a multi-signature wallet and a single master private key isn't enough for recovering the wallet. Assuming the wallet is 2 of 2, two master private keys are needed. Assuming the wallet is 2 of 3, two master private keys and one master public key are needed.

I tend to make backups of all private keys on a air gapped computer...............
What do you mean by "all private keys"? If you mean the private keys electrum gives you if you select "Wallet" > "Private keys" > "Export", note that they can't be used for recovering a multi-signature wallet. You must back up the seed phrases or the master private keys.

The transaction has failed because the sender used low gas. The fund is now on the casino wallet and they should send the fund to you in another transaction or credit the balance to your account instead. If they haven't done so, the only thing you can do is to contact their support.

If I had the 2 private keys to a electrum multisig wallet but no seed words to recreate the wallets, could I still send the funds from the multisig wallet using those 2 private keys.
To be able to import the wallet into electrum, you need two master private keys. Electrum allows you to create a multi-signature wallet from master private keys. But it doesn't allow you to create a multi-signature address from individual private keys. If you have individual private keys, you can use coinb.in.
