Re: Two word seeds?

Just to note, be careful backuping this new dictionary file if you intend to use that new wallet and seed. If in future you'd need to reinstall or upgrade Electrum, and recreate the wallet (with your seed), then you'd need also the same file to generate your wallet addresses and keys. So you'd be dependant not only of your seed, but also of this file.

That's not correct. Electrum doesn't depend on any dictionary. You can restore without having the dictionary on hand.

For example:

sensuous 4478 plentiful scribble schematic 6525 sloppy pesky 7002 bobble

Try restoring using the above seed.

Very interesting! I didn't know that. So it means the dictionary used to create a seed can be used only temporarily? Then, with that seed generated, I can safely restore the wallet in another PC with the default electrum installation?

It’s better than what I’m getting (-32601 ‘Method run_cmdline not supported.’) Grin

Are you on windows? CLI access isn't available on Windows. It may work over RPC.

I’m guessing one word seeds aren’t very secure then Grin. 11 bits of entropy for a word? I’m guessing that’s to prevent underflow?

It's 11 because the default dictionary is 2048 words (2^11). If you use a larger dictionary you can encode more bits. You can replace the default dictionaries with your own if you like. Here's one with nearly 9k words. It's a combination of the electrum dictionary and one I downloaded from the EFF's site. On linux you can replace the Electrum dictionary in /lib/python3/site-packages/ele colctrum/wordlist directory.

Ah that’s quite cool. I think I have every word in the Collins English dictionary somewhere so that’ll be interesting to try...

Is electrum happy to go over 256 bits of entropy?

Just to note, be careful backuping this new dictionary file if you intend to use that new wallet and seed. If in future you'd need to reinstall or upgrade Electrum, and recreate the wallet (with your seed), then you'd need also the same file to generate your wallet addresses and keys.

If all you want it for is your personal use/transactions, the Electrum Personal Server is easy to setup and can be run on a pruned node.

As mentioned above , here is the link:

https://github.com/chris-belcher/electrum-personal-server/blob/master/README.md

That's very nice, I see it's for Linux, but is there any way to run it on Windows?

EDIT: yes, I saw that it run on Windows (just need to install Python), along with Electrum & Bitcoin Core. My question is if I need to install a full node of Bitcoin Core to run this Electrum Personal Server?

Re: 12 word vs 24 word seeds

On a side note, you can increase the oroginal 12 word seed with the "extend the seed with custom words" option. So you can add more 12 words or symbols, numbers, etc, by yourself, and the Electrum wallet would have the same entropy (or more) than a 24-word seed.

Sorry, but, why don't you just use Electrum for example to generate the wallet for you?

Re: electrum wallet - lost btc - money transfer which was not my own
by

There may be other tutorials posted. I think you need to move all your remaining BTC from that wallet, and create a new one.

Preferably by using Bitkey (https://bitkey.io/) or a safe PC. Always keep this seed offline, write down on a paper. To send BTC, use a watch only wallet (with your new XPUB key), and sign the transaction in Bitkey (the Cold-offline mode)

It's just a draft idea, you can find a more detailed explanation on the other topics here on the site. But the main thing is. Create a new wallet (offline), send all your funds there, discard completely that old wallet. And never put your seed or private key in an online PC/Mobile.

Always try to use the mobile wallet as "watch-only", by only entering the xpub key. Keep your seed always offline, that is, use a safe envronment, like BitKey or Tails to sign a transaction and then broadcast it now with your mobile or on PC. As said, it's quite risky to keep your private keys on Android.

I can provide you 1000 Telegram members for 5$

Those are real members or bots? Can the channel be reported for adding many members like this? Is it safe?

Without knowing the password length, unfortinately buying wallets like this is like buying a lottery ticket. Granted, you may try to crack the password with many tools, but the chance to succeed is unknown.

Re: electrum wallet file restored but cannot open file

As a last resource, could you open the wallet file you recovered in Notepad? You didn't mention if the file was encrypted.

If you didn't use a password in that wallet, your seed will be readily available to you to copy and restore the wallet, look for this part in your wallet file:

    "keystore": {
        "seed": xxxx xxxxxxx xxxxxxxxx xxxxxxxxxx xxxxxx xxxx..........

Of course this only would work if you didn't use a password when saving that file.

I also believe that the most basic is the lack of sufficient knowledge about crypto currencies. It is the general people who is afraid to invest in crypto.  Also, the safety of investing is a big issue for them.

If you lost your seed (which is the most important part, it would allow you to recreate the wallet), and can't use the Google authenticator, the situation is unfortunately very difficult. Don't you have a backup of your seed anywhere else?

You mentioned a private key, did you follow these steps? https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/

Our planet has been going on to the hottest and the coldest weather so far. The nature has been sending signs to us that the Earth might collapsed one day and people is affecting little by little. I wish to address this issue more. And since the creator bestowed us the right to live in this planet, I hope for more organizations and more people to do something so that we can prevent the nature's destruction.

Unfortunately, all heads to a scam that the OP has fallen. It's a local transaction that appears on the screenshot, showing that whooping amount of 177k BTC. Mostly likely, the scammer showed that wallet, with the saved transaction, and asked for money, for it.

I may be completely wrong, in these points (which would be hopefully the best for the OP), but how come someone would send this amount in BTC to a wallet and sell it. That alone would be a big red alert. Hope if that was indeed the case, the OP didn't lose too much money on this.
