Bitcoin Wallet - was ist das? - CHIP

After I downloaded a file reader that doesn’t support .dat files, my backups of my Bitcoin Core wallet are now in VCD Video File format...please help.

I’m not sure how to get rid of this problem now that I have installed this file reader app on windows 10, but any advice would be great as to how I can get the files back to .dat format. Also, one thing I noticed is that when I save the file to the usb drive, the format is in .dat format but then it automatically converts it to this other format.

Help recovering from old wallet.dat for an old friend.

Hey all,
I've been in the Bitcoin space since early 2012.
I have a situation that I would love to get some assistance with, I will explain the situation momentarily. Please do not message me and ask me for the wallet.dat file it's not going to happen.
I have an old wallet.dat file from late 2012 or early 2013 from a coin I sold to a friend. Tried to recover the coins in 2018 and failed, later found out that someone had access to the computer and could have easily stole them. Would the current Bitcoin Core be able to read an old wallet.dat file, and is there any way to easily view the balance of a 2012 wallet.dat file without having to load the entire blockchain?
In the early days of Bitcoin as many of you OG's know, the only option to securely store your coins was to use the default Bitcoin wallet in a wallet.dat file. A friend of mine was really wanted to invest in Bitcoin but didn't know how, so I sold one to him because I didn't want him to get screwed. I installed Bitcoin QT on their home laptop, had him write down the password on a piece of paper and had him put a backup of the wallet.dat file onto a USB.
Fast forward to when the price went to $20k plus, he calls me up super excited and said he wanted to sell his coin because he could use the money and I encouraged it because from my prior experience I knew the momentum was unsustainable and I had sold a few coins of my own.
Anyway, I go over to his house and we huddle around his computer. He tells me that he upgraded the hard drive in his computer and gave me his old one and I went back to my house to get an external hard drive reader. I came back, booted up his old drive and remembered that we would have to let it sync up in order to get the coins out, and on his internet that wasn't going to happen anytime soon. He gave me the hard drive and I went home and left on Bitcoin QT overnight and in the morning I was shocked to see that there were no transactions on the wallet. Quick note, he had the wallet password in a file on his documents titled "Bitcoin Wallet Password.txt". smh.
I started to panic, and I realized how bad this looked on me. I called him and told him that there were no coins on there and asked if he had his USB stick and he told me he had lost it years ago. I frantically looked through all of my old wallet files to find any transaction that could link to his address, to show that his coins were still in there. After a while I realized I had sent the coins from the now defunct, and had no way to check up on the coins.
I did everything in my ability to try to recover lost data from the hard drive to no avail. I asked him if anyone else has had access to his computer, and then asked him how he replaced his hard drive because I know him well enough to know he wouldn't pull apart a laptop to replace the hard drive. He told me he took it to a shop to have it replaced a few months earlier. I suspect that I'm either trying to view the wallet incorrectly or whoever replaced his hard drive snooped on his hard drive, stole the coins and replaced the wallet.dat file and generated a new one. I have to admit, I was relieved a little bit to have an explanation to coins not being there but I could imagine he thinks I may have had something to do with it. I made a few more attempts over the years whenever I was reminded of the situation to no avail.
We kind of fell out after that and haven't spoken in a while. Recently, I saw a post on his Facebook that his wife is pregnant they are having a baby, and that's why I'm here. I would love nothing more than to be able to message him and let him know that I have 11 grand waiting for him, because I'm certain the money would mean the world to him during such a stressful time.
Any help or insights would be incredibly helpful and appreciated.

BAT Community Weekly Update: 02/16/2018 to 02/22/2018 — Bart Baker (10M subs) promotes Brave, interview with Brendan, big YouTube channels coming onboard, ETHDenver reflections, Ethereum wallet + hardware wallet support coming to Brave

Welcome to this week's community update! Now back from ETHDenver and seeing big adoption among major YouTube channels. Check it out! Thanks to MurphD for his invaluable contributions.
Short interview with Brendan Eich about BAT, Brave and JavaScript /w Panama Crypto
“The Basic Attention Token (BAT) forms the basis of a blockchain-based digital advertising platform. The BAT reconnects users directly to content creators, and reduces ad fraud and improves reporting for advertisers, without compromising user privacy and anonymity. The BAT platform cuts out all the parasitic middlemen in between brands, publishers and users, to make a much more efficient and accountable ecosystem.”

HowToBasic (10,300,000 subscribers) is now a verified YouTube Creator!
We’re seeing more and more channels come onboard, both large and small. HowToBasic has become famous with its… intriguing videos… now with 10.3 million subscribers!
Bart Baker (10 million subscribers) asks his audience to download Brave; video then locked by YouTube

The BAT/Brave team made an appearance at ETHDenver last week. It was a great experience and the team was excited to meet with countless fans and members of the community. Jennie, Luke and some cherished BAT community members (special shoutouts to miyayes, dragespir) answered hundreds of questions at the BAT/Brave booth.
The BAT/Brave booth was especially popular; publishers, advertisers as well as users were lining up to speak with the team and learn more. We had many people come and express their love for Brave, as well as newcomers of all kinds!
BAT/Brave also had two hacking teams at the event, (1) one of which created a fun retro game called Vapor ( while (2) the other implemented an Ethereum wallet into Brave (see above).
Luke participated in a panel on designing cryptoeconomic models, see the video here: link here

Zengineering Podcast: Episode 052 — with Jonathan Sampson, on Brave, Basic Attention Token and Browser Security
“In this episode, Jonathan walks us through the history of the internet and web browsers. We discuss Brave’s CEO, Brendan Eich, the prolific architect of the JavaScript programming language, and a founder and former CTO of the Mozilla Corporation. This story is compelling and important to the state of the modern web, modern software, and the entire planets intoxication with digital communication.
We dive deeply into web technologies, the digital advertising revolution, internet search, the history of web browsers, an intense appreciation of digital privacy, the future of technology, and digital crypto-currencies like Bitcoin and Basic Attention Token (a foundational component of what the Brave team is working on). We believe Brave Browser and its team are doing something that is both technologically innovative and deeply important for our digitized world.”

BAT/Brave Mentions:

Brave Browser Readers Just Gave Us Some Eth – is This Actually Working?
That’s our dashboard, so it’s not much and at current BAT prices … but it is something, and it is free.
The key to massive innovation in crypto
BAT is mentioned on a great article on Hacker Noon.
BAT and You; What I learned from the BAT team at ETHDenver
What’s Brave, YouTubers’ new favorite browser?
Brave is an open-source web browser that YouTubers are using in wake of the platform’s evolving policies. Included within the browser is Brave Payments, which the company introduced in beta in September 2016. The idea behind the Payments tool is that users should be allowed to choose who can financially benefit from their clicks without having to sift through ads — or feeling guilty about using ad blockers.

News You Should Know:

Google's new ad-blocking rules show its massive power online, and some smaller players are concerned
Google's dominance of the online ads business — in conjunction with the dominance of its Chrome browser and its influence on the group that selected which ads count as "intrusive" — raises some thorny questions.
Chrome's default ad blocker strengthens Google's data-driven advertising platforms
Google's browser now blocks certain ad formats by default. This move is less about improving the browsing experience and more about forcing publishers and advertisers to switch to Google’s data-driven advertising platforms.
Something to think about

  • There’s always a middleman in the ad space: BrendanEich @BrendanEich At least one middle-person in any advertisepublisher relation: the user. Brave is the user agent, we take fixed fee always less than user share (70% revenue to user for private opt-in ads; 15% to user & 70 to pub if both consent to in-page ads), & no user data goes off device. 6:20 PM - Feb 18, 2018
  • What’s the point of BAT, and do users of the web have rights? BrendanEich @BrendanEich The point is to send revenue back to your favored sites & creators anonymously — Web is not going to fund itself. Replace the ad tech complex with private/anon analytics, self- or (bigger idea) auto-funded.
  • BrendanEich @BrendanEich Users have rights to block ads/trackers/scripts, but many see ecosystem problem of free-riding that way. Some can afford to pay & Brave enables anonymous contributuons, automated and/or pinned by user. Not all can afford, so private BAT ad option is coming, to pay for contribs. 6:53 PM - Feb 18, 2018

  1. run Help>Debug>Console
  2. write “checkwallet”
  3. if wallet checks aren't passed, please write “repairwallet”
  4. write “rescan”
Can I buy SpeedCash on YoBit?
SpeedCash Wallet on YoBit is currently under maintenance, and we do not know when they will be done.
But you can buy on there and let your amount be resupplied by the developers.
Here are the steps to do that:
·Move your cursor over your username in the upper right corner and click on “Yobit Codes”
·Select SpeedCash, choose amount and click on “create new code”
·Copy and paste the YoBit code (YOBIT…SCS) and send it together with your wallet address (desktop wallet, paper wallet or exchange wallet) to the developer at [[email protected]](/)
Can I deposit SpeedCash on Yobit?
No, you can't.
Why and when will SpeedCash end being mineable?
Proof-of-Work will end at 1kk block. After the 640k block, there will be no rewards for mining.
Why would I want to use SpeedCash and not just Bitcoin?
SpeedCash has a variety of advantages over Bitcoin, e.g.:
·Untraceable, which means you can send money anonymously
·Fast block time of 20-30 seconds
·Built-in messaging functionality
·Energy-efficient PoS algorithm, gradually replacing the common/outdated PoW algorithm
·BURST feature, with which a transaction can be confirmed within 2-3 seconds
·Documents Vault feature
Was SpeedCash an ICO?
No, it was not.
Usually there are two ways for a cryptocurrency to grow and receive money for development: performing an ICO or being pre-mined.
SpeedCash was slightly pre-mined to cover the costs of exchange listings, web designers, professional proof readers, etc. A pre-mine burn took place in January 2018.
What is the SpeedCash max. supply?
SpeedCash is inflationary and does not have a maximum supply.
The total SCS coin supply is 476,918 SCS with an 8% annual increase.
Expected coin supply:
Jan 2019 (PoW ended): up to 476,918 SCS
Jan 2020: up to 515,071 SCS
Jan 2021: up to 556,227 SCS
Jan 2022: up to 600,779 SCS
Jan 2023: up to 648,841 SCS
Jan 2024: up to 700,749 SCS and so on.
This inflation is not something to worry about as the total amount of coins not only increases, but also your own amount by staking.
What is staking?
“Staking simply stands for holding a cryptocurrency in your wallet for a fixed period, then earning interest on it. The reward that one earns from staking varies depending on the length of the time that they hold it. The longer the stake duration, the higher the returns.“
How do I stake my SpeedCash Coins?
Simply by having your desktop wallet open, online and unlocked.
Is SpeedCash compatible with hardware wallets like Ledger Nano S?
Currently not. We plan this integration with hardware wallets and security tokens in Q3 2018
How can I restore my SCS wallet if I format my computer?
Always make a backup of the wallet.dat file. With this file, you can restore your wallet.
Are anymore exchange listings planned anytime soon?
We have contacted 10 more exchanges with requests to list SCS. Negotiations are in progress.
When will the whitepaper be published?
We will officially announce this when we have a fixed date.
Why did my wallet stop minting?
If your wallet stopped minting and you have a balance of more than 10 SCS, you can do the following thing to reengage the minting process:
- Send part (half is an optimal value) of your amount to another one of your addresses. You can create the address on Receive Coins page of the Desktop Wallet. Standard commission will be charged (~0.01 SCS). After sending the amount to your wallet, it will continue minting within 4 hours interval.
This is not a complete bug, rather a Proof-of-Stake Velocity trait. We hope that we can make this procedure automatically in the next release.
What is the “Vault” feature?
VAULT technology allows a user to validate document authenticity without disclosure of the document data by storing document hash on the SpeedCash blockchain.
What is the “BURST” feature?
BURST (Blockchain Usage Regulated & Sustainable Tweaking) makes it possible to have short speedups on the real network for any relatively big stakeholder for free. The best recorded confirmation time with BURST activated was around 2.5s. That is 300x faster than Bitcoin and almost as fast as masternode solutions.
I have a special talent/skill to offer, who do I contact?
Any helpful contribution is warmly welcomed and evaluated. Please contact [[email protected]](/)
