Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Dave Bitcoin of walletrecoveryservices.com just cracked a wallet for me (whose passphrase I lost in May).

Background:
In May I got the "brilliant" idea of beefing up the security of my BitcoinQT wallet by replacing its password with a longer passphrase. Somehow I managed to mistype the passphase twice. I tried every thing I could think of (adding spaces, inverting capitalization, etc. etc.) but without success, even automating the guesses with a simple script from someone on bitcointalk.
Eventually I wrote the coins off and my next wallet passphrase was typed with extreme caution. (Plus I switched to using Armory where the paper backup feature is a nice safety valve.) I gave the wallet.dat file to a few people who contacted me via the bitcointalk forums, and thought that was the end of it.
So last night, I'm obsessively watching the BTC-CNY exchange rate like everyone else, when I get an email from one "Dave Bitcoin" who announced that he had cracked the passphrase (after more than 5 months!). In short order he sent me 2.0 of the original 2.5 BTC in the wallet (keeping a finder's fee we had agreed to when I originally sent him the wallet file, not that I was in a particularly good bargaining position).
It was a very pleasant surprise that he (a) was able to crack the wallet, and (b) was honest enough to return the coins. He mentioned in the email that part of his motivation for (b) is that he has started a business doing wallet recovery. I figure the least I can do is vouch for his competence and integrity. So all you morons out there who lost a wallet like me, consider using Dave's services at http://walletrecoveryservices.com/.

01-13 07:43 - 'Lost Bitcoin passphrase: Does anyone have any experience with the new recovery tool Passware Forensic Kit?' (self.Bitcoin) by /u/NitrousNed removed from /r/Bitcoin within 5-15min

'''
Here's my situation.....
I know this is an all too common problem (and you've probably heard a lot of similar stories) but I'd appreciate any advice I can get. I purchased some bitcoins back in 2013. They were in a Bitcoin-QT wallet on my now very old and slow Macbook (which I still have). However, I wrote my passphrase on a piece of paper that is long gone now! I'm well aware that without the passphrase or seed phrase I'm unable to recover the coins.
HOWEVER, I might know part of the passphrase - but not too sure. I've now created a new BitcoinCore wallet and have imported the located the wallet.aes.json or wallet.dat file from the old mac (just waiting for the initial synchronization which should be finished in a couple of days.
I know it is difficult (if not impossible) to crack the passphrase via brute-force but I just heard about new Forensic software called Passphrase ([[link]2 ) that apparently has the ability to recover lost bitcoin passwords from Bitcoin.info and Bitcoin Core wallet services. It is very expensive (USD$1,095/year) but just wondering if anyone has used it before or knows how effective it will be in my situation.
Hoping someone can help!!!!!
Thanks

I'm giving away Bitcoin

Hi guys. I realize this is pretty dumb, but I've lost the passphrase to my old Bitcoin Core wallet. I've tried quite a few bruteforcing apps with no luck (duh), old backups(no use), wallet recovery services(not interested) et cetera.
Thanks for staying this long with me. Almost there. So, why I'm here is - I'm going to share my old wallet.dat's and ask y'all to crack them. As a reward you can keep 50% of money in the wallet, which is 5$ and not a cent more. That should make around 70$.
Now, I perfectly understand that if you do manage to get the money, nothing would be stopping you from taking all of them. Well, on the other side I believe that it still would be better than the money laying w/o use. Besides, Redditors are awesome.
The passphrase is about 13 digits long, with no repeating symbols. The minus is that it can contain any keyboard symbols (Uppercase, lowercase letters, numbers, and [email protected]#...) The files (wallet.dat backups) are up on google drive - https://drive.google.com/drive/folders/0B3eCKZXI79O8aklyUUk5WXBtWGc?usp=sharing I wish you good luck.
P.S: Sorry for the, uhm, title.
P.P.S: English isn't my native language, so have some mercy.
P.P.P.S: I can provide any ownership proofs. Say, dance around my PC with transaction history onscreen?
P.P.P.PS: Yes, I'm fully aware of the fact that I'm not very smart.

need help recovering my wallet.

So i bought some coins thru coinpal in 2011. I have the email which contains the bitcoin address that the coins were sent to, at some point in 2012 or something, i lost interest in bitcoin. reformatted and repurposed the drives, etc. but i did backup my wallet files, and after searching i found a wallet.dat file that is compatible with the old bitcoin qt client
under the recieve tab, it shows 3 addresses, one of which has no label, The second has the address contained in the email from coinbase, and the third has another address that i believe i had sent coins to at some point.
The two "labels" i can search on blockchain.info and they both have a balance. HOWEVER.. when you right click copy address, it copes an entirely different address.
this address has a zero balance. in all 3 spots.
So ive tried importing the wallet into bitcoin core, it does not show anything, so i know this is an older file created by the older bitcoin qt client.
ive run several commands in the debug console, trying to dump the private keys, but for some reason the wallet file i have does not contain the private keys for the two addresses that have coins.
I had someone trying to help me but he says the wallet is encrypted.
so i opened the debug console and tried to unlock the wallet using the passphrase i think i would have used, and it tells me that the wallet is not encrypted
which makes sense because i remember specifically not encrypting the wallet because i always forget passwords.
Whats weird is, how did these addresses get put into the label section of the recieveing tab? i know for a fact that one of them which contains 2btc i could have manually entered myself, because i do have a record of the address on my email from coinpal.
the second one tho, i have no idea where i would have found the address. They both have one transaction right around the same time, and they both have a balance. one of 2btc, one of .4 btc. the transaction dates line up to when i bought the coins.
im having data recovery done on my hard drives at this point to look for more bitcoin wallets, because im pretty sure i had more bitcoins in there as well. at least 6 or 8 more that i can remember.
So is it possible that the wallet file is corrupt? if so is it repairable?
or is it more liekely that ADDRESSES listed in the recieve tab are the actual addresses contained in the wallet file, and the labels are something else? im ripping my hair out trying to figure this out.. I have a wallet file. it has 2 addresses listed which i can verify both have a balance, but i cannot gain access.
i remember in 2011 buying some coins, and like the next day my computer crashed and got stuck in a boot loop so i had to reformat. and i remember backing up my wallet on a flash drive, and trying to restore it and the coins not showing up even after the blockchain loaded.
i have not yet finished loading the blockchain on my bitcoin qt app, so maybe that has somethign to do with it, but i find it odd that these addresses do not have the correct private keys.
any ideas?

Encryption walletpassphrase on Bitcoin core wrong

Hey everyone, Let me start with some background info. After sending my bitcoin originally to my bitcoin core address, my unknowing self decided it might be a good idea to delete everything including the wallet.dat (had no idea what I was doing). I used recovery software to retrieve the wallet.dat but there was some overwriting done. Enough that when I open core, A message appears that reads, "error reading wallet.dat! All keys read correctly but transaction data or address book entries might be missing or incorrect." Also, when I go to the console command line and try to enter my walletpassphrase to unlock my wallet so I can dump the private keys, it says that walletpassphrase is incorrect. I am almost positive that what I wrote down is exactly what I entered when setting up the wallet. Along with trying what I wrote down, I also tried unlocking the wallet with hundreds of slight variations to no avail. So what my question is, did deleting the wallet or the overwriting of parts of the wallet make the encryption passphrase no longer valid or different? Also thoughts on whether the partial overwriting of the file will prevent me from obtaining the private keys or not are appreciated. Lastly, if anyone has any alternative methods to brute force the wallet pass phrase they would be greatly appreciated. I heard about [email protected] and if anyone could share their experiences with them if they used them.

Found 1 possible wallets Found 221 possible encrypted keys Found 0 possible unencrypted keys
Possible wallet #1 with passphrase #1
Private keys not decrypted: 221 Trying all the remaining possibilities (221) might take up to 0 minutes. Do you want to test them? (y/n): y
Private keys not decrypted: 221 Try another password, check the size of your partition or seek help The wallet is encrypted and the passphrase is correct
Importing:
The new wallet /home/ubuntu/Desktop/recove/recovered_wallet_1513352751.dat contains the 0 recovered key [email protected]:~/Desktop/pywallet$
So it recognizes the password as correct, but it doesn't decrypt the keys.

Hitting the Wall [Part 3]

If you missed the previous parts:
Part 1 Part 2
Let us continue. Fear not those who have kept up so far - we are almost there...
When you’re playing your favourite game you’re always moving forward. Anything you do is a step in the right direction. If you fail you get to start back at checkpoint somewhere – this is true for most games, Day Z probably being one of the exceptions. The point is, you get a sense of that progression – it’s a nice feeling and it keeps you going.
What happens when you don’t get that sense of progression?...
Friday 28th March – still here. It’s now the afternoon and I’m staring at my monitor. The progress bar moving along at a snail’s pace with a message telling me ‘weeks to go’. Agonising. Some of you probably think it’s over, move on, you only invest money that you can afford to lose, etc. Your right, couldn’t agree more. The problem is hope. I mentioned in Part 1 that I class myself as an IT savvy person and in Part 2 that I like a good challenge. Well this was it – I wanted to see if I could make use of that knowledge and find a break through. Earlier that day, after my wife woke up, I told her what had happened, she listened intently. Her response? ‘You’re a clever IT guy, I’m sure you will find a way.’ I chuckled a little.
So what else can I do? Dave Bitcoin hasn’t got back to me yet. Is there anything else out there? Turns out there is: Enter TheGrideon.
They have developed a Bitcoin Wallet Password Recovery application. Windows installer? Check, CPU & GPU utilisation? Check, Brute Force / Mask Based / Dictionary attacks? Check, check and check. Price? FREE FOR PERSONAL USE. Now were talking.
Installation was as easy as 1-2-3. As soon as the application ran it detected my two AMD cards and the CPU I was using. All that was required was to point it to the wallet.dat and supply it with some information. Magic.
I played with it for a bit, testing its capabilities by attempting a simple brute force and supplying characters I thought made up my password. It started ticking away; 10 passwords a second, 100 passwords a second, 30 seconds later 2500 passwords a second (!) before finally settling on 4500 passwords a second (!!!). This was it, if I was ever going to crack this passphrase, this would be the tool that would be the tool to do it.
Friday the 28th March had come and gone. Seemed like a bit a blur now that I think about it. There was so much going on in my head that time seemed to fly by.
I got stuck into the application, made sure I knew exactly how it worked and therefore how best to utilise it. As I was progressing I got an E-mail response from Dave Bitcoin! (Hurray). He’d got my messages and the information I supplied was fine however he asked a couple more specific questions; How sure was I about the characters I sent, what attempts have I made, etc. Ultimately he brought me back down to reality: a 12 + character password will be an impossible task if I can’t be more specific than I was.
I guess hope is one of those things you cling on to until there’s no hope left. I didn’t want to give up.
I supplied Dave with the additional details, gave him a general confidence rating. It was enough to get him started. In the back of my mind I was already thinking I shouldn’t be relying on Dave alone and so I continuing doing my own thing.
Saturday rolled around and I was still at it – I’d realised there was a little problem with the application; it didn't have a permutations option. This was a pretty big deal. As I mentioned in Part 2, permutations is the one thing I was 100% certain about… so I e-mailed their support team. Fantastic is the word that comes to mind when I refer to their support team. They were not only on the ball, they were bloody quick about it. I received a response within the hour. Their software was unable to handle permutations however they directed me to the dictionary functionality and mentioned that there are some online permutation generators that I could use to build a dictionary. It was the saving grace for the application.
I immediately jumped online and searched for permutation generators. I found this little gem. It was perfect for what I needed. It accepted prefixes, suffixes and allowed for 10 characters to be entered. Since I had a good idea of what my prefix and suffix were there was a lot of potential for this to work. I began using it straight away.
8pm Saturday. Where the hell has the day gone? I had literally been working through the entire day doing nothing but creating dictionaries, supplying the application with those dictionaries and sitting there staring at my screen. Nothing. Not a single dictionary I had created / used returned my passphrase. I was beginning to hit the wall.
In answer to my question at the beginning of this post; sense of progression is everything. It’s pointless to continue. You give up. You stop playing.
I removed myself from Reddit, from Dogecoin and from my laptop for a while. I stopped thinking wallets and passphrases altogether.
You know what they say though….. It’s not over until the fat lady sings [Part 4]
tl;dr
  1. Google F****** Keep (didn’t think I was gonna forget you!)
  2. Response from Dave Bitcoin, he offered his assistance!
  3. Found another tool to help password recovery
  4. Full CPU+GPU support – 4600 passwords a second!
  5. Found a permutations generator for dictionary creation
  6. Attempted millions and millions of permutations
  7. Nothing, not a single dictionary contained the passphrase
  8. Frustrated, angry and ultimately feeling defeated - I give in.

Road to Recovery [Part 2]

If you missed Part 1 – check here! The story continues! (tl;dr at the bottom)
Where were we… ah, my alarm.
No sooner did I jump into bed than the alarm went off! Buzzing away under my pillow… the day was fast turning into one of the worst days of recent memory.
I grabbed my phone, switched the alarm off and just lay there mumbling.
‘A1 something something something £9 something something’
‘No, that’s not right’
‘A1 #?’
‘What was it – I know this, come on … visualise!’
I’ve never done that before… I was speaking to myself out loud, that was the gravity of the situation and my feelings at the time. I hate you Google Keep!!...
My wife on the other hand had already dozed off (btw, I got plenty of confused.com looks during the panic station ‘moment’, she was half asleep though so it didn’t really faze her).
Eventually I began to calm down. I started thinking sensibly about the situation. The first thing I was doing wrong was not writing down any of my guesses. I probably recited well over 30 phrases as I was lying there. I got up, opened my laptop and started writing them down. At the same time I noticed my mining rig was still running... RDP -> Hit Q on CGMiner – why the hell was I mining coins to address that I no longer had access to!!!!
Once the fans slowed I opened the QT client and went to the send tab. Bear in mind that from the moment I lost my password to this moment I hadn’t even attempted a single passphrase even though it would have been a little fresher in my mind!
Send tab -> check the addresses I have saved -> ah DogeTipBot -> that will do. 100 coins, hit send… ‘Please Enter Passphrase’. Ok here goes:
First attempt
‘That’s the one for sure...’ Nope
-Tries again- No
-and again- Error
-A further 15 times- Access Denied.
Sigh
F*** you Google Keep. (Yeah your gonna see a lot of this – I despise that app now). I must have tried and failed countless times before I decided to investigate other options.
What do you do when you’re stuck? Google It. And that’s what I did. There were a fair few posts regarding lost pastphrases, none of them really helpful. Most replies were along the lines of ‘sorry for you loss’, ‘how much did you lose?’ and ‘nothing you can do…’. Well, screw that, I wasn’t giving up – I like a good challenge!
Enter Recoinvery.com. A nice little tool albeit very slow. I came across it whilst searching for passphrase recovery options available to me specifically for coin wallets. You basically point the tool to your wallet.dat file, set a bunch of options and hit the ok button. It runs a few instances in the background attempting to recover your lost passphrase.
Let me stop there for a sec and explain something quickly about passwords and recovery of one (feel free to correct me if wrong!):
  1. If you’re trying to recover a password less than 10 characters that you can’t remember at all then there’s a decent chance for you to recover it – it may take a while though, could be months.
  2. If you know bits and pieces of it then you can drastically reduce the time it takes for recovery using things like dictionaries or masks
  3. If your password is 10 characters or over and you don’t know parts of it then you’re pretty much screwed
There’s more to it than just that but those are some of the key points most recovery websites will throw at you. Another vital point I learned was the difference between combinations and permutations – it goes a little like this:
If I have a password ‘Abcd123’ then there’s no reason for me to check combinations – I.e. aaaaaaa, aaaaaab, aaaaaac, etc. We’re not interested in combinations here, were interested in permutations. With permutations you would provide a character set and a length you are after – this would then output unique permutations of the character set vs. the length – using the password example above, if I provided Aabcde12345 as the set and 7 as the length I would see things like Aabcde1, Aabcde2, Aabcde3, etc. (Remember ‘A’ and ‘a’ are not the same)
Why is this key for me? I was 100% sure that I hadn’t used the same character twice in my passphrase.
So, back to Recoinvery. As I said, great little tool but I quickly realised it was far too slow for what I was trying to achieve. There had to be other services out there.
There were tools like Hashcat and John The Ripper, both great for expert hackers / crackers but for me, a novice when it comes to this type of activity, I found those tools a little out of my league. At this point I came across www.walletrecoveryservices.com – a service provided by a guy called Dave Bitcoin. You’re thinking what I’m thinking right? Scam Scam Scam. Best course of action? Google It.
Dave was apparently the real deal. His method was a custom made bit of code + access to numerous workstations / servers and the use of only a small section of your encrypted wallet. This is key – the portion he was asking for was essentially useless, he wouldn’t have been able to steal my coins had he recovered it. I read up on it and him – everything seemed above board. I proceeded to contact him.
In the background, I had Recoinvery chugging away at measly 100 passwords a second – it had been running for hours I think (btw this is still Friday the 28th March) and nothing. My guess would be somewhere in the region of 500,000 combinations had been checked of a 12 character password (+ it seemed a little … buggy). Wait you say? I’ve not said a word about what parameters I’ve used or what the hell it was that I was trying to look for! Fear not, details below:
  1. I was fairly sure my password was not less than 11 characters and certainly no more than 13
  2. I knew it had unique characters, symbols and numbers
  3. I knew the start and the end of the password – 99% confidence
  4. I was about 60% sure about the characters contained within the password
It was the bit in the middle that had be stumped. The good news was I was able to provide Recoinvery with a mask – set a prefix, suffix and let it chug away at the middle. The bad news, as highlighted earlier, I was struggling with permutations and speed. It was frustrating to say the least.
Approaching the half day mark with nothing to report I decided to check back on Reddit to see if any more comments had been made that may guide me (I made the most in the morning before 9). A couple of useful comments however nothing to go off. I guess it was time for a little patience… woosaaaa.
I should probably get some breakfast… (12.00pm)
Am I doomed? It's looking increasingly likely I know .... Hitting the Wall [Part 3]
tl;dr
F****** Google Keep
Calm down – think sensibly
Research password recovery, find Recoinvery
Give Recoinvery some character sets to work with
Sit and wait.

(On 23rd March 2015) Wallet Recovery Services is AWESOME!

Hi everyone. i would like to take a moment to share my personal experience for having mistype my passphrase/password for my Digibyte Desktop Wallet.
It all began when i changed my old passphrase to a new one. How i would normally do it was to first type out a random password in notepad that has upper and lower cases, numbers and special characters. Once done, i would copy and paste it into the passphrase box. Lastly, i would refer to the notepad and write down the password onto a piece of paper.
3 months later and after several deposits, i wanted to withdraw some Digibytes. When i referred to the piece of paper and typed the passphrase, it didn't worked!!! I tried again thinking that i might have mistype. And then i tried every other password that i thought i might have mis-copied and paste. Everything failed. It was difficult for me to recall exactly what happened since it was 3 months ago.
I tried Recoinvery. But it didn't worked out so well for me. I did thought of trying the Ruby Method but it was much too complicated.
I was about to give up and thought that i should just keep the wallet.dat and hopefully somewhere in the nearby future, some service would appear.
But Lo and Behold!!! it has already appeared ever since 2011: WALLET RECOVERY SERVICES. I was skeptical at first, not knowing much about it. But as i researched more and read the reviews, comments and testimonials that others had given about it, and saw that it has been kept well up-to-date by being able to offer their services for not just Bitcoin but for altcoins as well...i thought i should give it a go. Furthermore, it mentioned that Blockchain.info redirects their clients with forgotten passwords to this service.
About 5 hours later after sending an email to Wallet Recovery Service, i received an email...with good news - my passphrase had been successfully decrypted!! THAT WAS FAST! And it was all because of a mistype - a "$" was included into the password somewhere in between, an additional character. Either i mistype the passphrase twice (really? twice? facepalm) when i change it OR i have no idea how i could have missed that when i copied it down onto a piece of paper. And guess what? among the 25 passwords that i had created, the one i mistyped had to be the shortest one (14 characters long). The ironies...
I will be leaving a link to this GREAT Service: http://www.walletrecoveryservices.com/
I know i'm not an old timer here on Reddit. But i don't exactly have any other way to prove that this is a true story. I guess i could at least share my activities on the Digibyte Forum. That should helped a bit i hoped. Here is my profile:
https://bitcointalk.org/index.php?action=profile;u=224866
If you are still not convinced, then one way is to do your own research about it, read through all the testimonials and the information provided on the website about how to get it done.
Thanks for reading everyone. This service will be MUCH SOUGHT for in the future when we have more people coming into the Bitcoin and Altcoin Scene. Let's help to keep it alive and spread the word!
Once again, THANK YOU Wallet Recovery Services!!! ()/
