what about dusts btc balances? those 400 bitcoin actually came from about 100 plus addresses. about 80 addresses do have sufficient amount, the rest do have dusts balances.
You seem to be keeping the result from online broadcaster to yourself, was it an error? Or you didn't because of privacy reasons? FYI, in terms of privacy, it's basically the same as pasting your address to their site. If you're thinking that they can get your keys, no; or change the output, no, it's impossible without you changing the SIGHASH type which is " all" by default ( changing anything will invalidate the signature). So why don't you try to broadcast it through a blockexplorer instead? BTW, please don't dodge this question: Did you bought that wallet.dat or was it given to you by a " friend"? Because the balance is suspiciously identical to those tampered wallets that has been circulating in the internet. |

Sadly it can't, that's a totally different issue about the older versions of Electrum ( or other wallet) that can import uncompressed private key and generate SegWit address from it. When the user try to create a transaction, he will find out that it wont be accepted by nodes as it's non-standard. The only solution to that ( off-topic) problem is to directly send the signed RAW transaction to a mining node ( eg. Solo miner or a pool) and include it to a block. |

So they described it as " Ratcheting Addresses". It's possible to retrieve all of your future private keys even without a specifically designed tool and technical knowledge but that includes trusting online tools for HMAC-SHA256 calculation and HEX to WIF private key generator like bitaddress.org or walletGenerator.net. To try the online workaround ( use a no-balance account for testing): - Go to http://extranet.cryptomathic.com/hmaccalc/index and tick "enter as HEX:", then paste your "chain_private_key"
- On the "Key:" box, enter 0001 if you want to restore "wallet_address_n":0 or first address, 0002 for the next and so forth.
- Change "MD5" to "SHA-256" then click "Calculate" and copy the result.
- Go to either walletgenerator.net or bitaddress.org, go to the "wallet details" tab and paste the result from the previous step.
- Now copy the "Private Key WIF Compressed" that starts with either 'L' or 'K'
- Import it to Electrum with "p2wpkh-p2sh:" like my examples from the previous posts.
Sample: localcryptos-wallet-2020-01-05.json: -snip-

Important Be sure to save your raw transaction data in a safe place, because anybody with access to it will be able to spend your coins.
Whoa whoa, why is this written in trezor's official wiki? The RAW transaction doesn't contain his private key, it can't be recovered from the signature or redeem script. It's also impossible to change the output without changing the signature unless they sign it with SIGHASH flag like SIGHASH_NONE  The only issue there is his privacy if he decided to share it. Maybe the article meant: " spend it without your consent"? |

This is what's written on their FAQ page about the wallet backup: If you forget your password or if LocalCryptos were to ever go offline for some reason - you can still access your wallet using this backup.
Unfortunately, the tools for interacting with the backup file are limited and complex. We are planning to publish more tools shortly which can be used offline to recover wallets from backup files. I can't find the " tools" that they're talking about but they mentioned that it's a full backup of the wallet. They didn't disclose what tool to use and the term " chain_private_key" which is used by LBC too. I tried to import it too, i got a different address.
Just export them one by one ( procedure above - post#9) and import to Electrum with "p2sh-p2wpkh:" before each of the private keys. Eg: p2sh-p2wpkh:L4QDqo4qB4CWFo9JZseryeS98NkCQM7YDvmQ..._PrvKey2
p2sh-p2wpkh:L4QDqo4qB4CWFo9JZseryeS98NkCQM7YDvmQ..._PrvKey1 |

I tried to get .json file by sign up. "chain_private_key":"9b4cce7ae452b9596aca82d6ae368d50edc5906e648daff4bcc4bbb0bea667c7"}] I am not sure, Look like that's HEX private key insert there. I've tried this by importing the " p2sh-p2wpkh:compressed private key" to Electrum and it restored a different address than the specified " 1st address". It seems to be using " chain_private_key" as a master key or something. I'm gonna do some more tests to be sure. @ protrader786 Just export the private key of your addresses from localcryptos' wallet tab by clicking the ⬇️ icon in each of your ( funded) addresses on both Ethereum and Bitcoin wallet, one at a time. Then you can import those keys to a desktop or hardware wallet. |

Maybe try and use "bitcoin-cli stop" instead of just CTRL-C to shutdown bitcoind in the future?  I tried to check the log if there's any difference with proper shutdown and CTRL+C and I didn't noticed any major difference: Normal Shutdown: 2020-01-05T02:04:35Z tor: Thread interrupt

2020-01-05T02:06:08Z Shutdown: done @ Tycek So you deleted the datadir. You can assume that the issue was really a corrupted block after deducing the other attempts that you've made but it's still a mystery how. If I were you, I'd check for any hardware problems specially the RAM or the Mobo if the HDD/Sata is not the issue. |

-snip- But increasing it is difficult, because you have to redownload the whole chain even when you just need 2 GB more blocks when actually keeping last 50 GB.
If this still applies: https://bitcoin.stackexchange.com/a/46829, it will not redownload the whole blockchain. Core will just stop from deleting the older blocks until it reached the new prune size. So if you set an additional 50000MiB, it will not delete the existing blocks for about 9 months. |

if i do that, it wont double spend the transactions?
I won't, it will be a double-spend if it's a different transaction ( with a different hash) spending the same UTXO. What you will do is simply re-broadcast the same transaction to another node instead of your own. I already suggested you this three days ago ( post link) to check if the culprit is your node or wallet.dat's saved transaction history. |

1. Does it matter weather or not we leave our wallets from Electrum open after downloading, or should they remain closed when not in use?
It can receive bitcoins whether its offline or online, so just open it whenever you need to send funds. 2. I know it recommends storing Electrum on another device not connecting on-line...But until I'm able to get another device to put in on, is it still ok to use going on and off line?
There's no problem with it as long as your PC have no viruses or vulnerability. BTW, your bitcoins aren't stored in your device or wallet, it's in the blockchain ( each full node's copy) and only controlled by your " private keys" which is stored in Electrum's wallet file ( encrypted if you set a passphrase). That security measure is to protect those keys and the device itself from hackers. 3. Lastly, if I'm sending bitcoin to an onion site through (tor) instead, should I or do I need to do anything differently?
No. |

Where did you found those info? The only offline storage that you can use is through cold-storage setup which requires two devices: a PC/Android and another PC/Android or a hardware wallet. Here's how to set it up: https://electrum.readthedocs.io/en/latest/coldstorage.html" Store online" must be the the regular setup. Just make sure to download the file from the official website: electrum.org
Update: I just discovered 'Documentation', so there's at least a chance now I'll figure this out. I guess I'll have multiple wallets somehow - is that right?
These are the two documentation that you might find useful: |

Does that include deleting the whole datadir?
Might have been a corrupted block file(s) because of improper shutdown,
have you encountered any sudden power-loss or have you been shutting down your PC without properly closing bitcoind?

Nvidia gtx 960 1.2 mh :-)
( lol) Even my previously idle i3-4130 is mining with 3 threads ( left 1 thread for obvious reasons) @ 2.4 - 2.7 MH/s. That's for a fraction of your GTX 960's electricity cost. |

Unfortunately none of the above works with my wallet
How about my suggestion above, have you tried to check for the TXID of those transactions and paste them in multi-currency block explorer? And now that you have the list of addresses from the dump file, you can paste one of the addresses instead of TXID and that site might detect which coin/wallet it belongs. |

I created a wallet in another wallet and tried to open it in Electrum
I tried to register a new wallet in Electrum
You mean these two are different tries? Yes? So for the first one, use " Standard wallet->I already have a seed" and you'll need to click " Options" then check " BIP39 Seed" for the next button to be clickable. But it depends on the format of that seed from " another wallet" if you'll able to restore the correct addresses, what wallet was it? For the latter, Electrum doesn't have a " registration", just follow the guides above to be able to create a new wallet, do not follow any video guides as most of them are likely scam. |

It does take some hours for some transactions when the mempool gets stuck at higher SATs/byte due to more clog and the sender sent the coins with ~0 - 0.5 SATs/byte during that time. I was watching some transactions yesterday where some 0 fee transactions were not going through for hours during the mempool clog when minimum fee to get in early changed to 5 SATs/byte. -snip-
I just like to mention that the current minimum fee that a node with default relay setting is 1sat/B; the chance that a <1sat/B fee tx will propagate is close to zero. Those " 0.something/B" that you see on outdated/buggy blockexplorers like blockchain.com must have SegWit data in them that they fail to compute correctly  The addresses tab used to be visible by default and that led to people being confused about why they had so many addresses. They were under the mistaken impression that one wallet = one address. So they hid that tab by default and now you have people complaining about the receive tab handing out different addresses each time!
Isn't that " fix" counter-intuitive? Because it will eventually change after one transaction, then the newbie will think that his ( single) address changed. I think it has something to do with discouragement of " address reuse" which actually works for newbies.
@ davidshu1 It's impossible to delete replace an address from the " receive tab" without receiving funds to that particular address. But this topic looks like already solvedand the main issue must have been: after panicking from the " deleted address" ( 'coz it was replaced) you restored using the seed ( post#5) then just waited for the client to sync to be able to display the transaction that actually went through in the first place. We'll be glad if you can confirm this  |

I have question. Electrum have RUS interface? Maby i have hack-version? I know hackers are faking Electrum
Anyone can set it to any language in the " general" tab of the preferences. Maybe it used your PC's locale settings. I am create new Electrum wallet and check every word, several attempts
But button "Next" not active
What's the language of your ( mnemonic) seed? AFAIK, it wasn't case-sensitive and double spaces/enter should be valid as a " separator" as well. So the problem must be your keyboard's input. Try copy-paste instead of manual typing: - Create a new seed using "New/Restore", select Standard wallet-> create a new seed, select Legacy or SegWit.
- Copy (Ctrl+C) and paste (Ctrl+V) the seed to a (temporary) new text file.
- Then Copy the seed from the text file to the "next" window because for some reason it wont let you copy from the previous window.
- That should work since it's the exact copy of a valid seed; if it didn't, there something wrong with your downloaded Electrum
Note: if this worked, your seed written in paper wont be a reliable backup since you can't manually input it as a valid seed. Try to change the language to English first. |

While this functionality of creating a watch-only wallet is a "nice to have" and has as main feature the fact that funds cannot be sent out of that wallet,
why wasn't the feature of receiving funds in that btc address not permitted as well ?
These bold words are quite a headache  So, you're saying that " why is it permitted to receive funds using a watch-only wallet"? -It's for people that prefer keeping their keys offline but still able to monitor their funds; -after-all, any valid address can receive bitcoins whether it's imported/belongs to a wallet or not. Or " why isn't receiving to a watch-only wallet permitted"? -It's permitted as I explained above. |
