First up, sorry for the delay in replying... been a bit of a hell week waiting patiently for news of how many job losses are expected at my company due to Covid-19 and whether or not I'd be "above the line" based on seniority...  Will you be testing this unit by actually funding addresses generated by this wallet? It does seem like their firmware is open source but it looks like they've actually just modified trezor's firmware: https://github.com/bithdYep... I'll be throwing some funds on it and experimenting with various features of the unit itself and any associated software. I agree about the proprietary connector. Do they sell replacements if your connector breaks or is lost, or do you have to purchase another entire wallet? Bit of hassle since you can't even charge your device without it.
I honestly don't know if you can buy a replacment, but I am keen to know as well. So, I'll message the company and see what they say and will include the info in my full review. This one has a neat design but its thickness makes me a bit anxious and worried it may bend. It happened a few times to some things I tried to hold in my wallet, does the RAZOR feel sturdy enough to handle a little unintentional bending pressure?
It certainly feels pretty solid... and some very unscientific pressure application doesn't reveal any discernible "flex" in the unit. Having said that, I wouldn't put it in my back pocket and then sit down! As has been seen, there are a lot of phones that don't cope well with that sort of "abuse", so I wouldn't expect this unit to survive it either!  HCP, what I would be interested in when you test the device a little more thoroughly is that you try to make a comparison between Ledger&Trezor since you have them both (I think this is the case). What I can notice is that the advantage of this kind of hardware wallet is that it is the size of a standard card (or even smaller), and therefore can fit into any normal wallet. For those who do not want to draw attention with their Nano S&X, this kind of design is definitely an advantage.
That is my intended plan... to compare with both the Nano S and the Trezor ONE. Still, the price is not competitive with the Nano S or Trezor One, so i wonder if you think this device is worth $100+? I also did not find information on the total number of coins this wallet supports, all they say is "BTC, ETH, EOS, USDT, BCH, BSV, LTC, Zcash etc."
You're right, it definitely doesn't compete on price... but we'll see how it does on features. |

Looking at the dump again, trying not to dox myself, I see the extended private master key and then the plethora of addresses and private keys before them, as well as an hdseed=1, reserve=1 and hdkeypath=m/0... on each line. My keys all start with K or L, don't see any 5's and my addresses all start with 3. The other problem I'm seeing is how ill copy and paste over 4000 strings into Electrum.
The wallet was made around 2012, and could have been used up until around 2015, which is when my brother gave me the laptop.
These two pieces of this puzzle just don't really fit together... "3"-type addresses are "P2SH" addresses and prior to SegWit being introduced were mainly used for "Multi Signature" addresses. However, Bitcoin Core did not produce these address types by default... indeed, creating MultiSig addresses in a Bitcoin Core wallet was a very manual task! Also, HD wallet functionality was only introduced in Bitcoin Core v0.13.0... which was released on 23 August 2016!!!  So quite why a Bitcoin Core wallet.dat made in 2012 would have "3" addresses and an "hdseed" in it is very confusing.  NOTE that it is not possible to upgrade an "old" wallet to be "HD". You had to create a brand new "HD" wallet file. Personally, I suspect that this is not in fact an "old" wallet at all... but is in fact an empty wallet.dat that was generated fairly recently (within the last 3 years or so). |

Definitely. Well, update. Somehow, I got my money! It's in my account. Hallelujah!
So the money ended up in your "Empire" account? Sounds like you got super lucky on this one... congrats! I hope this hasn't put you off using Electrum, it's definitely one of the better lightweight desktop wallets that has some really awesome features. It just has a few "gotcha!"s that can catch out new users. Take the time to read the advice given here and, if in doubt, just ask questions before putting large amounts of $$$ or BTC at risk!  |

But in the event of the seed being leaked, that's what I understood from OP, wouldn't the attacker be able of importing it without the need of the passphrase? I imagine how the scenario would be with say, electrum wallet, and if I have a seed, the it doesn't matter that I loose the password.
Even if you put your words in Electrum, you'd only see the "default" wallet... unless you clicked the "Extend this seed with custom words" option:  and then entered your "passphrase". NOTE: A BIP39 Passphrase is not the same as a wallet password . They're completely different concepts as you can see from DireWolf's explanation regarding the BIP39 passphrase. Without that passphrase, the 24 words alone are not enough to generate your passphrase protected wallet. You can test by using Ian Coleman's "Mnemonic Code Converter". Generate a new random seed mnemonic... and note the "BIP39 seed" and some of the private keys/address. Then type something in the "BIP39 Passphrase (optional)" box. You'll see that as soon as you enter anything, the "BIP39 seed" changes and then all the derived private keys and addresses also change. Having an empty "BIP39 passphrase" is like the "default" wallet in Trezor and Ledger etc... putting anything in that box is like using a "passphrase". Whereas, the wallet "password" used in something like Electrum is simply for encrypting the wallet data... but you can change that password without affecting the wallet addresses being generated. |

The "wipe code" is also an interesting feature that they have added... basically a "dummy PIN" that just instantly wipes the device!
As they say, "You can write the wipe code somewhere near your Trezor as a decoy PIN, so that if someone tries to unlock the device without your consent, they will cause it to wipe itself." That's a pretty nifty little feature, imo.

About 7% per year, I wouldn't stake anything with less than $10k to make it worth it. Other than that I consider it a waste of time.
True free money it is but staking with for example $1k to make $70 or less in 1 year?
7% is a bad return? If you know anywhere else you can get a 7% return... let me know Of course, there is no guarantee that 7% TRX is going to equate to a true 7% ROI in $$$ terms given the volatility of crypto markets... that could effectively be 0% if TRX tanks... or it could end up being 700% if TRX moons. The issue I have is that I can't even see the form to try and enter... it simply returns "Error 3". (and yes, I did disable all the adblocking)  |

I have used my Xpub which i derived from a native segwitt wallet on Ledger to receive payments.
From where did you exactly copy the public key in the Ledger Live? Did you select 'Edit Account' and then copy the key from the 'Advanced logs'? I suspect this is exactly where the issue has arisen from. For some reason, Ledger still shows legacy xpubs... for native segwit accounts!!! This *should* of course be a zpub. The end result, being that Electrum will likely be generating Legacy addresses... This can be confirmed by going to "Wallet -> info" menu in Electrum and checking the "script type". It will say "P2PKH" and your addresses in Electrum will start with a "1". Electrum will only generate "bc1" (aka bech32 aka native segwit) addresses from a "master key" if that master key entered is "zpub". Unfortunately, you can't just do that now, because you funds are on legacy addresses The "Good News"™, is that your funds are able to be recovered. The "Better News"™, is that you can recover them, without needing to "expose" your Ledger seed!  The process would be: Setup- Ensure that your Ledger Live is NOT running (just helps prevent USB connection issues with Electrum - Ensure that your Ledger device is connected, unlocked with PIN, and you have opened the "Bitcoin" app on the device (should say 'Application is Ready')  1. In Electrum, select: "File -> New/Restore" from the menu:  2. Give the wallet a name... something unique like "Ledger_XPubRecovery" and then click "Next":  3. Select "Standard Wallet" and then click "Next":  4. Select "Use a hardware device" and then click "Next":  5. Electrum should identify your Ledger device... click "Next":  6. Select "legacy (p2pkh)" option... and then change the derivation path to: m/84'/0'/0':  This is the important. So, make sure you set the options exactly as shown! - be careful that you select legacy first, then change the derivation path, as every time you click one of the options at the top, the derivation path will reset to default! 7. Choose whether or not your want the wallet file encrypted, I'd recommend to "uncheck" the box, otherwise your device MUST be plugged in to open/view the wallet, then click "Next":  NOTE: NO PRIVATE KEYS will be stored in the wallet file. So it is "safe" to have it unencrypted. Having it not encrypted simply allows you to open the wallet and treat it like a watching-only wallet without the device attached. At worst, if someone steals the wallet file, it'll compromise your privacy, but not the security of your funds. 8. Enjoy access to your funds! |

I have a technical question.
A wallet is protected by a password, which encrypts the key.
Is it possible to "merge" two encrypted wallets into one and have a completely new database, if they are encrypted with the same password?
Is there any paper on how the encryption works?
Which wallet application are you referring to? As not all wallets use the same encryption methods/standards. Are both wallets from the same app? I suspect this is an " XY problem. What are you actually wanting to achieve by merging two wallets together? What is your specific scenario/reason for wanting to "merge" 2 wallets? |

In situations like this... it is probably better to use an existing solution like BitMaxz has suggested.
Generally, you create an HD wallet (NOT on the same server etc, but offline or Hardware wallet etc) and then take the "Master Public Key" from that HD wallet and put it into your eCommerce/Bitcoin gateway... A decent eCommerce/Bitcoin gateway solution should be able to generate addresses as required from the Master Publick Key, and link those addresses to client accounts.
Meanwhile, your private keys are all safely kept elsewhere and when you want to sell, you just use your wallet software to send coins as normal, it'll be able to handle having coins in all different addresses just fine. The only real consideration you have here is to try to avoid getting "low value" inputs (aka dust). This is why a lot of exchanges and gambling sites etc have minimum deposit amounts.
The real trick will be finding an eCommerce/Bitcoin gateway that works for your setup. But I think BitMaxz suggestions should be a good starting place.

Honestly... the cynic in me thinks this is just someone who has managed to steal "aquire" a wallet.dat from somewhere that has "several" BTC showing in it, but they obviously lack the password and sufficient hardware to attempt to crack it and they're just attempting to get someone else to do the heavy lifting to bruteforce the password... Unless the "reward" is placed into escrow, I'd be inclined to stay well away from this. Otherwise, go talk to Dave @ https://walletrecoveryservices.com/ They also have a thread here on Bitcointalk. He has a proven track record of helping to recover passwords. |

I am wondering if there is a way to flag that address as fraud? Or some thing I can do about this event? Any ideas is appreciated.
Some of the exchanges have flagged things before, but generally only in the instance of a massive hack and theft from either themselves or other exchanges. You can't really blacklist bitcoin addresses... and the thieves are likely to simply move the coins through mixers or other addresses to obfuscate their history. You only real option at this point is to make sure you learn from this and take the necessary steps to prevent it occurring in the future. Sorry for your loss. |

DISCLOSURE - BitHD sent me this unit for review.
So, after a somewhat lengthy wait due to the Covid-19 situation, the package arrived! NOTE: Click images for large version Card included for scale, As you can see, the box is shrink wrapped and also has a security seal on the box... there is plenty of debate as to the use of security seals, which I'm not going to get into here. But you can see below that the seal shows up as "VOID" once it is pealed. 
The BoxThe box itself is relatively understated... just a black logo on "dark grey" box (the box is actually a lot darker than the photo makes out)  Close up of Security seal...  I don't read Chinese... but Google Translate "live view" to the rescue!  As mentioned, once pealed... the seal indicates that it is "VOID" 
Box ContentsSliding the draw out of the outer box reveals some paperwork  Under that is the unit itself, sitting in a custom fit foam enclosure  Underneath the unit was a micro-USB cable, the micro-USB to power "blade" adaptor and a couple of "recovery seed" cards 
The UnitThe unit itself certainly lives up to it's RAZOR moniker... it's VERY thin...  And very small in the hand... the aluminium alloy back just has the BitHD logo on it. Has a nice premium feel to it.  On the bottom, we have the charging socket... it's definitely a proprietary connector...  The front has the screen (monochrome OLED) and 2 buttons...  You can see here that the unit is actually slightly smaller than a standard credit card (the white outline in the 2nd pic is the card behind the unit)  
The "Paperwork"Standard 12 word recovery seed cards (2 included)   An advertising pamphlet with some details on other BitHD products (Double-sided, in English and Chinese)  The "User Manual" (also double-sided, in English and Chinese)   Was a little confused that there was no "verification code" in the box visible on the last page of the user manual... but then I found it on the chinese side of the user-manual : 
"The Blade"™ proprietary power adapterNote, I'm not sure if that is what it is actually called, but it fits with the RAZOR theme and it's less than 1mm thick!  As we can see, it is a micro-USB adapter. 
Notes: Quick teaser video I made of starting it up for the first time: https://www.youtube.com/watch?v=cSLo_o4uXCA (apologies for the stupid audio, needed something "license free" and I was in a hurry ) BitHD RAZOR website: https://bithd.com/BITHD-Razor.htmlSelling on Amazon for US$99.99 + shipping
A full review will be coming soon™... In the meantime, if you have any questions, feel free to ask.

I lost an electrum password.there is not much, only 0.5 btc, can you help me?
Is that Electrum wallet on your mobile device... or is it the desktop version? Do you not have the backup phrase (12 words?) If it is on the mobile, you'll probably find it a bit difficult to get the wallet file without having root access to the device... without access to the actual wallet file, then johntheripper is of no use to you. |

I downloaded armoury 0.96 and it worked fine.
Do you also have Bitcoin Core downloaded, installed and fully synced? Armory relies on Bitcoin Core block data to be able to build it's own internal databses. If you do not have Bitcoin Core (0.19) installed and synced, your Armory will not work correctly. You won't be able to see transactions and updated balances... and you won't be able to send coins. Also, what OS are you running on? I find it strange that you are not able to install 0.96.5... but I can tell you that your current version of Armory, 0.96, will not work correctly with the latest Bitcoin Core etc. You need Bitcoin Core 0.19 and Armory 0.96.5 to have any hope of getting it all working properly. |

Getting onboard with bitcoin needs to be a straightforward as possible if we want mass adoption. People losing money to this scam is the fault of Roger Ver, not the fault of his victims.
It's a shame that all the egos, politics and posturing got in the way of bitcoin moving forward in a united manner. Now we have several forks all claiming to be the "true" bitcoin and clowns like CSW getting his face in the media making up all sorts of bs. This division has definitely caused harm to the entire cryptosphere in my opinion... but hopefully those burned due to the confusion generated by all the shenanigans will not be put off cryptocurrency completely. |

Hi I saw your Post as i am trying to retrieve my misssing character how would i run this code on a mac book pro?
It's a Python script... a MacBook Pro should have python install by default. You just need to copy/paste the 'script' from that post into a text file, edit the 'corrupted_wif' value to be the WIF of yours that is missing one character and then save the file as "corrupt_wif.py" or some other name... as long as it ends in .py You will also need to make sure you have the python bitcoinlib library installed. So open a 'terminal' and type: Once that is installed, you then change the current directory in the terminal to where you created the .py file... and use: That should run the script for you. This very short video shows how to create the script using the text editor and run it: https://www.youtube.com/watch?v=Txt-cLLa_vo |

How can I send the balance from all 1000 bitcoin address to my main btc address?
Can I ask why do you want or believe you need to consolidate all the BTC into one address? If your wallet contains all the keys belonging to those addresses, then you will be able to spend the all the coins regardless of what address the coins are associated with. Your wallet software should handle that just fine. By consolidating all the coins together you're creating unnecessary transactions and wasting money on fees. |
