101  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Core wallet spends BTC 0.07!! USD 4000!! to make two small dust sendings on: December 06, 2021, 03:59:57 AM
The last thing is that I somehow do not understand this Bitcoin, address, account, wallet,  Bitcoin Core,  thing properly. I think I understand it, but I could be misunderstanding the whole account address wallet thing. I see from my ledger that there must be something I do not understand.
Bitcoin doesn't really have "accounts" per se... they're more of an abstract concept that some wallet applications (like Ledger Live and other BIP44 compatible wallets) use... for the wallets that do implement "Accounts", because they are generally HD (hierarchical deterministic) wallets constructed from seeds, they will indeed have multiple keys/addresses for the "accounts".

Bitcoin Core, whilst it is an HD wallet, doesn't use the concept of accounts anymore (that functionality was deprecated a while back). So, with Bitcoin Core, you have your wallet.dat and it holds many keys/addresses. Like other HD wallets, this is generally because it is trying to provide unique addresses for all your receive (and change) activity in an attempt to prevent "address re-use".


I find it hard to understand how to find on Blockchain the content of my Bitcoin account as I see them in my Bitcoin Core client and my Ledger client. It seems to work different from Ethereum. I am quite confused. Can one account have more than one account address???
This can indeed be somewhat problem to go to an explorer and work out what your wallet balance should be as you could be looking at 10s or 100s of different addresses with UTXOs etc (depending on how you have been using the wallet).

It's essentially why wallet applications are used... they hold all your keys (and therefore know all your addresses) and are able to track everything for you. The issue you're running into is that your Bitcoin Coin wallet.dat files, being old, are not currently synced and therefore, potentially not giving the correct balances.


This is generally very much unlike ETH, which tends to use the one single key/address for your entire "account"... so it's a simple lookup on the explorer.

Thanks for coming back and updating us... and that's good news that you had a positive outcome in 1. Getting your funds back and 2. Getting some substantial gains! Wink

Still, it isn't great that you had to wait for 8 months!!?! Shocked Shocked

Better late than never, I guess.
103  Other / Beginners & Help / Re: Signature campaigns and taxation. on: December 03, 2021, 09:37:39 PM
How do you state the cryptocurrency income from signature campaigns in your tax return?
My guess would be that, rightly or wrongly, most people just don't declare it at all. After all... "Bitcoin is aNoNyMoUs!" Undecided

Some countries have defined laws now regarding cryptocurrency and income and capital gains and how this should be declared etc... some don't. And I dare say that there is probably a significant proportion of people who don't even realise they are required to pay taxes on their crypto assets and income derived from such.

However, generally as far as the taxman is concerned... "Ignorance is not an excuse" Tongue
104  Other / Beginners & Help / Re: Please, help me understand. on: December 03, 2021, 09:31:18 PM
... both increased returns and minimized risks could be important.
These 2 things are generally mutually exclusive... or to put it another way, risk and return are generally proportional.

As one increases, so does the other... as one decreases, so does the other.


The unicorn of investing has always been the "low risk, high return" investment. I'll just say that history shows that a lot of money has been lost betting on "horses with a horn glued to their heads"... Wink
105  Other / Beginners & Help / Re: Has my data been breached? on: December 03, 2021, 09:12:20 PM
Indeed, that SMS message is from someone attempting to login or reset your password etc.

So, it seems someone has got to your email/login details as they work through the data dumps from the many, many security breaches Undecided  They'll have scripts setup to test each one and see if they're still valid and/or work on other websites as well... Don't be too surprised if you start getting more "Password reset" links or other security warnings from various places.
106  Bitcoin / Electrum / Re: BTC stuck in Electrum multi-sig (will pay $1k reward) on: December 03, 2021, 09:00:01 PM
Yes the Ledger Nano S works correctly with Ledger Live
Also, I don't have Ledger Live open when running Electrum
...

I tried opening just the Ledger wallet, and it still couldn't find the device
If the Nano S is working fine with Ledger Live, then it would appear that the issue is specifically with Electrum and it's Ledger plugin. You might want to raise an issue on the Electrum Github Issue tracker: https://github.com/spesmilo/electrum/issues

Note that the Devs will require that you're trying this on the latest version of Electrum (currently 4.1.5) before they offer any support.
107  Bitcoin / Hardware wallets / Re: Ledger Firmware Update? on: December 03, 2021, 08:50:11 PM
What can you tell us about its size? With new features such as Taproot, I assume the firmware takes up even more space from the limited internal memory. Did you notice less storage space for the crypto apps on your Nano S?
Apparently it uses more space, so there is less room for apps... the current Capacity is 138Kb, which is slightly less than I remember from the last update. I only have 2 apps installed on it anyway... so I didn't really notice if there was any less space. Space has never really been an issue for me. I'm not holding 759843 different coins/tokens... and I rarely trade/switch between the ones I do have. Tongue

I however was somewhat surprised to see that the Bitcoin app is now a whopping 62kb. Nearly half the available space just for Bitcoin. Shocked

But I think maybe thats just some kind of rounding error.
For what it's worth: There are not supposed to be any rounding errors in Bitcoin. It's exact, up to the last digit. If it doesn't add up, something is wrong.
Given that it appears the OPs wallet is not synced, the changes to the balance were most likely a result of the wallet syncing in the background and adjusting the wallet balance as new transactions were found and processed.
109  Bitcoin / Bitcoin Technical Support / Re: Unconfirmed BTC transaction on: December 03, 2021, 12:33:41 AM
It was 1sat/vB but the transaction is .5 BTC.  Not sure if that makes a difference.
No. the amount being transacted makes pretty much no difference in terms of transaction priority. It is almost exclusively the fee rate being paid.

As at 00:30 UTC, Friday, 3 December 2021... there are only around 8 blocks worth of unconfirmed transactions... and the vast majority of those are all using 1 sat/byte fees... If network conditions stay the same (no guarantees), there is a relatively good possibility that your transaction will get confirmed in the next few hours without requiring any intervention.

However, if you have an urgent requirement to have the transaction confirmed, then I would agree with the others that using Electrum+Ledger device to bump the fee via RBF is the best course of action.
110  Bitcoin / Bitcoin Technical Support / Re: Tying BTC to PKI keys / certificates on: December 03, 2021, 12:25:27 AM
Yeah... I guess one flaw is that the "bounty" sent to the "PKI wallet", would need to be sufficiently large that it would actually make an attacker want to steal it.

For instance, if you only send $100... and they could potentially make thousands from exploiting access to the PKI in other ways, then they could just ignore the BTC in the wallet, steal thousands from abusing the PKI access and the entire system fails.

Also, with this system, you're potentially tying up large amounts of money, to "prove" that the keys are "safe"... which doesn't really prove that the keys are safe anyway... it just tells you that no one has moved the coins. Either way, you're likely losing out on a substantial amount of money. It's either stuck in the wallet, or an attacker steals it.

Even if the other party was "staking" their own BTC to prove that their keys were safe... it still doesn't really prove that at all. Just that no one has moved the BTC.
111  Bitcoin / Bitcoin Technical Support / Re: Help recovering 2015 wallet.dat on: December 03, 2021, 12:15:32 AM
If you don't have space to run a full node with all the block data... running a pruned node and working with old wallets is going to be very frustrating! Undecided

Every time you want to open an "old wallet" that was last used from outside of the time period that match the blocks still on your disk, you'd need to redownload the entire blockchain again. This can take many hours, if not many days Undecided

The ideal solution is a full, unpruned node.

If you absolutely need to run it pruned, then you might want to edit the bitcoin.conf file (or start from the commandline) and pass in the -wallet parameter as many times as necessary to open all of your old wallets at once.

Code:
-wallet=<path>

Specify wallet path to load at startup. Can be used multiple times to load multiple wallets. Path is to a directory containing wallet data and log files. If the path is not absolute, it is interpreted relative to <walletdir>. This only loads existing wallets and does not create new ones. For backwards compatibility this also accepts names of existing top-level data files in <walletdir>.

For example, if you had the following wallet files:
old_wallet.dat
wallet_2015.dat
my_wallet.dat

You could start Bitcoin Core:
Code:
G:\Bitcoin\bitcoin-qt.exe -wallet=old_wallet.dat -wallet=wallet_2015.dat -wallet=my_wallet.dat



I get this error when I try to rename the exe to add -reindex.



You don't rename the .exe file... you "append" the -reindex parameter to the end of the command... You either need to create a shortcut to the bitcoin-qt.exe and then edit the properties for the shortcut to change the "target" like so:


NOTE: make sure that the path to the bitcoin-qt.exe and the "start in" are relevant to YOUR setup... Based on your screenshot, I would guess instead of C:\Program Files\Bitcoin... it should be G:\Bitcoin for your setup.

Alternatively, just launch it from a "Command Prompt" window (Start, type: cmd)... then enter this command:
Code:
G:\Bitcoin\bitcoin-qt.exe -reindex -wallet=OldWalletFileName.dat -wallet=OtherOldWalletFileName.dat


That'll start up Bitcoin Core GUI, opening your old wallet.dat files... and start the reindexing process... This will likely require downloading and validating the entire blockchain again... but when it's finished, all the old wallet.dat's that you open should be "synced" and ready to use.
112  Bitcoin / Electrum / Re: BTC stuck in Electrum multi-sig (will pay $1k reward) on: December 02, 2021, 11:54:51 PM
The wallet is set up as a 2/3 multi-sig wallet, with #1 being Electrum, #2 being Trezor One, and #3 being Ledger Nano S.

When I try to sign a transaction with Electrum (and then sign + broadcast with Ledger Nano S), it won't work because Electrum won't detect the Ledger Nano S.
When I try to sign a transaction with Electrum (and then sign + broadcast with Trezor One), it won't work because of the error "DataError: Expected input with amount".
Another thought occurred to me... Do you just have one wallet file setup within Electrum... or did you create different wallet files for each hardware device using the Master Public Keys from the other device and the "normal" Electrum wallet? Huh

I was just mucking around testing some stuff... and found that the Ledger detection could be a bit "inconsistent" with multiple wallets open within Electrum... sometimes it would find it, sometimes it worked first time, sometimes it just refused to find it no matter how many times I rescanned etc.

With just a single wallet open, it was much more reliable, finding the device every time.
113  Bitcoin / Development & Technical Discussion / Re: Bitcoins "stuck" in Sparrow Taproot Wallet on: December 02, 2021, 09:52:52 PM
Yeah I think it's a bug, obviously someone else has the same problem https://giters.com/sparrowwallet/sparrow/issues/311

Luckily I only sent like $15 worth of bitcoin. Should better be more careful next time
It seems that this bug has been fixed in the new 1.5.3-beta1 release: https://github.com/sparrowwallet/sparrow/issues/311#issuecomment-984853015

So, maybe grab the new beta version and see if that works for you.


On a side note, that giters website is dreadful. It doesn't handle the markup in the comments very well Undecided
114  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Core wallet spends BTC 0.07!! USD 4000!! to make two small dust sendings on: December 02, 2021, 09:43:57 PM
Are you using the GUI Bitcoin Core client, or running commands from the command line?  If you are running the Bitcoin Core client... it should show you at the bottom of the GUI window if it is currently syncing.

Alternatively, just look at the "Window -> Information" menu item... and check what the "Current Block Height" listed is... if it isn't at least 712289, then your client likely isn't synced properly:



Until your client is synced, you won't be able to send any transactions, as the client cannot guarantee that your wallet balance is true and correct.
115  Bitcoin / Electrum / Re: sent btc by mistake on: December 02, 2021, 09:29:32 PM
as i considered nobody going to return money back. All the people i ve managed to connect were supports or owners of TG channels from variouscountries, they advised me to open my own group in my country as i already donated a good sum and receive donations like they do... unfortunately the mechanism working as like people just get profit in its own pocket, i don't believe anything is hitting Assange
That is unfortunate that you have been unsuccessful in getting your funds returned... from a genuine mistake.

It also seems a bit sketchy that you can just setup a wikileaks group and start asking for donations... I'd be very very hesistant to donate anything, knowing that this is how the whole thing seems to be setup! Shocked Undecided
116  Bitcoin / Hardware wallets / Re: Thoughts about Passport hardware wallet on: December 02, 2021, 09:19:30 PM
I did a few basic measurements; it seems it's not actually pulling a ton of power (though it should be possible to get that down as well), but the main issue is that the unit stops functioning when the batteries drop below I believe something like 1.3V.
...
So it's not actually draining the full 1.5V in a couple hours, it's draining 0.2 and not booting up after that. It makes you wonder if they even have a decent boost circuit at all or just running 3.3V electronics off 2 batteries LOL Cheesy
That probably explains why they advise using "1.5V Constant Voltage" rechargeable batteries... A lot of the "long life" rechargeable batteries often run below 1.5V, which seems likely to cause issues with this device. Undecided

Hopefully this is something they can rectify moving forward.
117  Bitcoin / Hardware wallets / Re: Ledger Firmware Update? on: December 02, 2021, 09:10:57 PM
So the last ledger firmware update was all the way back in May of this year.  Thus that is when I did the last nano ledger s firmware update.  Does anyone know when would be most likely the next update?
Well... looks like the answer was November 30th, 2021

They've put out an update to support Taproot amongst other things:
https://support.ledger.com/hc/en-us/articles/360010446000-Ledger-Nano-S-firmware-release-notes?docs=true


Update was simple enough... saw the "New Firmware" banner in Ledger Live, clicked update now... followed the prompts... it even has the "re-install apps" feature at the end of the process that will put all the apps you had installed back on the device for you.

The entire process took less than 5 minutes.

118  Bitcoin / Hardware wallets / Re: Ledger Nano S can't connect on: December 02, 2021, 09:04:19 PM
Honestly, the Nano S is somewhat notorious for being quite selective about which USB ports and cables it will work with... There are multiple threads on this forum and reddit with users having issues with certain USB ports.

The only hub I've ever tried it with, was connecting it through a USB port on my monitor... and that actually seemed to work fine.

I assume you're using Windows 10? Huh  If so, when you have the Nano S connected to the hub, do you see any "unknown devices" listed in the "Device Manager" app?
119  Bitcoin / Hardware wallets / Re: Trezor or Ledger !! on: December 02, 2021, 08:55:29 PM
This is really a "Coke or Pepsi?", "PC or Mac?", "X or Y?" type question... with no real right or wrong answer.

You're going to fine proponents of both... and users that dislike both, for a variety of reasons. I have both, and find that they're pretty much equally capable, and cost about the same when I originally bought them. They both had their pros and cons.

At the end of the day, you'll need to look at all the features of both, and likely the price point + shipping and make a determination as to which works best for you personal situation. While I would struggle to currently recommend Ledger due to the quality issues they have had of late, if the choice is between no hardware wallet or a Ledger, then I'd say, get the Ledger.

But don't necessarily ignore other wallets like Coldcard or BitBox either.

We are really spoiled for choice these days... and that is always a good thing!
120  Bitcoin / Wallet software / Re: Exodus security question on: December 02, 2021, 08:38:48 PM
is blockchain.com not able to import private key and add fund instantly ?, i remember a while ago a website has can add fund btc from private key right after import private keys instantly.
I agree with Pmalek, avoid Blockchain.com. It is simply not reliable and doesn't really support importing keys properly.

I would highly recommend you use Electrum: https://electrum.org/#home
and read the guide here on how to verify the digital signatures: https://bitcointalk.org/index.php?topic=5240594.0

Electrum will let you import private keys and will show the funds "instantly"... and it's a lot more reliable than blockchain.com
