This command will only dump the private keys, timestamps and addresses managed by your wallet. The fact that there is a new private key added in 2017 *could* mean nothing (on the other hand, it *could* mean a change address was added, and your funds *might* have been stolen).
Just import the private keys into electrum and find out for sure...

Good luck!

BTW: i'd personally not even post part of the private key... For example, the last characters of the private key in WIF format are a checksum, so if you post the first letters, you make a hacker's life much easyer (he doesn't have to brute force those first letters, and he can just forget about the last characters to, so he only has to find the middle part of the private keys).

should run flawless. I have both electrum and electrum-ltc running on my work pc (windows), they have a different workdir (C:\Users\[myusername]\AppData\Roaming\electrum and C:\Users\[myusername]\AppData\Roaming\electrum-ltc). At home i only run *nix based OS'es, but i don't have electrum-ltc installed at home.

If it worked, the file c:\walletdump.txt should contain lines like this
[private_key] timestamp reserver=1 # addr=[address]

or for a HD wallet:
[private_key] timestamp reseve=1 addr=[address] hdkeypath=[derivation_path]

you can potentially just download electrum, create a new wallet (chose the option to create a wallet using private keys) then copy/paste the private keys into the wizard's textarea.

It doesn't matter if most of the private keys belong to a private key/public key/address that is unfunded.
PS: only do this on a clean machine
PS2: like i said before: if there are unspent outputs (if the balance > 0), make a new wallet and empty out the old one.

you encrypted your wallet... You need to unlock it before you can dump the private keys

replace "your unlock phrase" with the actual password, and 3600 by the number of seconds you want your wallet to be unlocked.
Btw, only dump your wallet on a clean, secure machine, and never ever share the content of the dumpfile, not even partially!

Most people use some sort of image host like imgur or tinypic... Just create screenshots, make sure they don't display any sensitive data (like private keys, seed phrases, passwords, xprv's, passwords,...) then upload them to a free hotlink image host.
Those hotlink hosts usually even give you the BBcode you can copy/paste directly into bitcointalk.

here are screenshots from my wallet, you should see something similar, especially if you see a balance of +12 BTC

And the second command

So, we're talking about the commands:
and


That's strange, you should see the following:
This should show you that account "" currently has a balance of x.xxxxxxxx BTC. This balance only includes unspent outputs that were found in the blocks that are currently synced. If your wallet is still syncing, the balance can be incorrect.

The second command should give you the following output;

If your wallet is not yet completely sync'ed, it's possible the spending transaction are not yet visible. In other words: unless your wallet is completely sync'ed, it's still possible those +12 BTC might still "disapear" when the syncing continues.

Did you read my previous question? You gave a command output, but didn't say which command you ran to get that output. Is is possible to show us which command you executed?

Fixed that for you

https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison
A cortex A9 (a common cellphone cpu) hashes at 1 Mh/s ... Compare this with an S9 ASIC which hashes at 14000000 Mh/s. you'd need 14 million cellphones to have the equivalent of 1 Antminer S9. An S9 makes about $14/day (before power costs), so a cellphone would make $14/14.000.000 = $0.000001 /day... That's less than 40 cents per 1000 years. After you substract your power cost, the cellphone will give you negative profit (without a doubt).

Which command did you try?

Like others have stated before me: if a hacker hacked your dropbox and downloaded your wallet.dat, it no longer matters if you delete your wallet, encrypt it, move it... If the hacker hasn't already spent your BTC, you NEED to create a new, clean, encrypted wallet using a verified wallet software like core or electrum, then you need to create a new address using this new wallet, and then you need to empty your old (possibly hacked) wallet, and never use it again...

IIRC, the "listreceivedbyaddress 0 true"  command will only work AFTER the blockchain was sync'ed up to the point where the funding tx was confirmed. "getaddressesbyaccount """ will list all addresses belonging to the default account, the OP can then import these addresses as watch-only addresses in electrum, or he can look them up on an explorer.

You're right about the dumpprivkey tough... If he finds unspent outputs, it is solid advice to dump the private key, import it in electrum and spend the unspend outputs as soon as possible to fund an address generated by a new, secure wallet

you can list your addresses while your wallet is still syncing... Just open the debug window (or start from cli) and type

this should give you a list of accounts, then type

then, you can look up these addresses on a block explorer like blockchain.info

I'd also suggest to take it...

Coinwarz suggested dash as the most profitable X11 coin:
https://www.cryptocompare.com/mining/calculator/dash?HashingPower=900&HashingUnit=MH%2Fs&PowerConsumption=217&CostPerkWh=0
$35/month before paying for power, in my case a net loss of $7/month after paying for power.

Other algo's do a little better, but i could not find a single algo that would make more more than $15/month profit (after paying for power). If i had to bid on this item, i'd big $15*6 = $90 in BTC at current preev rate (shipping included)

If somebody wants to give you over $1000 (current preev rate), i'd say: make the deal before he/she changes his mind

Exactly, the OP was giving a fictional example, "what if everybody withdrew their coins in fiat"

I'm well aware of the bitcoin ecosystem, but the OP asked a fictional question, so i answered his fictional question: if everybody decided to dump their BTC, the price would fall to 0. If every HOLDER of BTC would dump their BTC, but there were sufficient new buyers (1:1) for every BTC sold, the price should stay roughly the same. If every holder sold all their BTC, but there was an increased demand from new buyers, the price would rise.

If EVERYBODY wanted to dump all their BTC, the price would go to ~$0/BTC... So yes, in this case there would be enough FIAT on the exchanges.
It's all supply and demand. If the supply is huge and the demand is 0, the price goes trough the floor.

if a mod deletes your post specifically, you get a PM
if a mod deletes a whole thread (all posts), including your post, you don't get a PM

Theoretically, yes, you are right... Each time there is a sustained fork, and the fork decides to use the sha256(sha256()) POW algorithm, there is a portion of the miners that mines the fork (if not, the fork would not be sustainable), thus cannot mine the original BTC.
That's the thing that happened with bitcoincash in the past.

However, the more i read about the coming forks, the more i believe that after a while almost nobody will still be mining them. I strongly believe that after the initial fad has worn off, most miners will see there is no profit in the forked off coin, and revert to mining BTC.

Also, don't forget: bitmain is still producing batches of S9's, so more hashpower is added to the network on a daily basis. As long as "the amount of miners mining the new coin" < "the amount of hashrate added at the same timespan" the diff will still rise.

bitcoin core = the reference client, bitcoin-qt is a graphical "shell" of the reference client.
There are many wallets, many of them are good wallets with a nice feature set. Some are more user friendly, others have other pro's and con's... Core is the successor of the first client, initially written by satoshi. Since bitcoin is open source, p2p, core is not the "default" nor the "best" client out there (by defenition... in reality imho it's one of the best ones out there tough), it was however, the first one.

https://en.wikipedia.org/wiki/Bitcoin_Core
https://en.wikipedia.org/wiki/Qt_(software)

If it's something you're only going to do as an extra service for clients, i'd defenatly suggest going for bitcore's implementation:
https://bitcore.io/guides/wallet-service

This way, you'd have a relatively time-tested service that seems to be pretty secure without having to re-invent the wheel and invest thousands of development hours to create a very basic wallet service.
