You can swap the firmware and use pretty much whatever wattage you like.

I've got one that is submerged in mineral oil with a pump loop & silent fans.. It's literally silent.

I really should plug it back in...
You can only use such an asic only when you have free electricity.
You can even without firmware update remove 1 board with chips and reduce power consumption.


IF you intend to sell immediately. Everyone seems to only consider current exchange rates. If you look at where things are going and consider the future value, it's a different story...

I've had mine running well as low as 600W at about the same efficiency as running at full power. That said, yes, the S9 is out-dated and highly inefficient by comparison to other ASICs now.

I sent you 2 messages to your email but you never reply, so when you going to reply? I was offering help as some others, is this a joke.

Just emailed you back. Thanks.

I'm not buying it. There are far too many "unfortunate events" to be realistic. Besides, you couldn't easily make a paper back up in Bitcoin's early days.
We see stories like this every month here.
Not sure why someone would make it up..
I don't know, you tell me!

The reason it has been such a pain to get this recovered and taken so much time is reactions like yours when it could have been a simple process.
Sure, blame me for your own mistakes.

That, and it was easy to make a paper backup back then. It was just a matter of writing down or printing a number of characters. An average English word is about 5 characters in length, so if you make a 12-word backup phrase, you're going to write out or somehow save 60 characters.
There you go again, making things up. There were no 12 word seed phrases "way at the beginning".

Come on, how serious are you? No details provided by you mostly at all, btw.
OP goes on Ignore. My best guess is he's hoping to earn Merit.

Good Lord.. Not made up. It's just bizarre how people want to assume it is. Good point, though, wouldn't be an issue if it weren't for the stupid things I did back then, won't argue with that. I'm just surprised at the level of, and focus on skepticism as opposed to desire to earn a lot of money for helping out. I'm fully aware there were no seed phrases back then.. My point was that it was as easy as writing down a phrase, just a comparison of the difficulty of writing it down.

Details I will provide in direct communication with people able to help out, so if you're interested, email me. Don't intend to be posting here once I finish what I'm doing, so I don't value getting any merit out of it. I've just got a lot going on, not checking this every day.

It's not like bitcoin core has a button you click and it prints out 10 neatly formatted private keys for you. Specially in early versions. You would have had to export them, format them in a way you could split it (as OP claims has done) and then print it out.
i'm sure it cant be that hard. all you need is a printer and copy/paste. even if it's 100 keys, that's maybe 3 sheets of paper max.

Quote
Besides why do you think OP means 10-20 keys when he uses the term "quite a bit"? It may be a lot more...
i don't think he ever even used his bitcoin. he just mined it and let it sit. so i doubt he has very many keys.

Quote from: DVCMI776
Mined quite a bit of Bitcoin way back at the beginning. Socked it away on a HDD, as well as on a flash drive in normal fashion, and paper backups.

Yep, wasn't difficult. Or just write them out.

Yep, never touched any of it. Wanted to let it appreciate. Regret it quite a bit.

He forgot to mention that his dog ate his paper wallets.
Or like this man, his mom found the paper wallet and trash it.
How do you safely keep your recovery phrase written on paper?

If people are not tidy enough but careless enough, their wallet backups will be left in public places, and many people can see these backups, or these backups are left in locations that are unsafe.

Yesterday, my mom did a general cleaning on my room and when she's done, I saw the recovery phrase of my Trezor hardware wallet on the garbage can which I placed on my computer table

Perfect example of how "unfortunate events" or unlikely things do happen..

Working with the hard drive, unfortunately all I really remember is that I stored the keys and other data in binary and hex formats.

Assuming you directly store 256-bit private key, rather than WIF or different private key format which have specific prefix/magic bytes, i don't see how anyone could do search effectively.

You've nicely summarized one major issue here in a succinct way.

Not sure why someone would make it up.. I wonder how many "stories" like this that you've seen every month could have resulted in you getting a significant amount of money for simply helping someone out instead of being skeptical that someone is just wasting time on the internet making up some ridiculous story. Things happen in people's lives. Not everything goes the way people plan. Plenty of people early on in Bitcoin didn't realize the value that what they were doing may have later on and forgot about it, misplaced things, or "life" happened. People do bad things to other people, especially over money. All kinds of ridiculous things happen to people that aren't talked about. I figured I'd leave the details out, but all of it is very reasonably explainable. That said, believe what you want, I'm not going to waste time arguing about it. The one thing I will say is this: The reason it has been such a pain to get this recovered and taken so much time is reactions like yours when it could have been a simple process. I guess I should have lied and said something more believable.

That, and it was easy to make a paper backup back then. It was just a matter of writing down or printing a number of characters. An average English word is about 5 characters in length, so if you make a 12-word backup phrase, you're going to write out or somehow save 60 characters. A private key isn't much more difficult, if not easier.

Mined quite a bit of Bitcoin way back at the beginning. Socked it away on a HDD, as well as on a flash drive in normal fashion, and paper backups. Since I mined quite a bit, I figured I'd let it appreciate and didn't really mess around with mining again until ~2017. For about 6 years now I've been working on recovering my old wallets.

Flash drive wound up being lost. HDD was broken after moving across country and after more than a decade it was between two drives, one of which wound up being unrecoverable after 3 separate data recovery facilities, and one that I was finally able to get an image of from the last facility. Paper backups wound up being tossed out, lost, or stolen over the years. Some I buried after splitting them into quarters and separated them geographically. After so long, it seems most have been built over with new construction after farmland being sold etc.

Working with the hard drive, unfortunately all I really remember is that I stored the keys and other data in binary and hex formats. I did not store them as regular wallets. I was pretty paranoid.

I've been able to recover some binaries that I'm not sure how to get converted back, and have chunks of keys that I recovered from paper and text files, but no full keys.

Anyone willing to help, I'm happy to part with 10% of whatever we can recover.

First, you should tell or describe the file name of any "file signatures from keys" backup that you have.

Usually, wallets/clients are specific with their backup naming scheme, the file name may ring a bell to some oldies here.
It could also indicate that it may not be related to bitcoin at all since the keywords "signature" and "private key" aren't totally exclusive to cryptocurrencies.

Problem here is, it was so long ago, I don't remember. .dats for sure, others should be just keys in .txt files.


I understand your request is about old wallet.dat files from the era of BitcoinGUI when there were no HD wallets common. Correct?

What exactly is the recovery scenario?
Do you need to scan storage media for fragments of (possibly deleted) wallet.dat files?
Or do you need to repair damaged wallet.dat files?
If you have wallet.dat files: where are those from?

I started my Bitcoin journey somewhere in 2011 and have a wallet.dat file that was created in 2011, but I might not have a backup of the file from 2011 or 2012. This wallet was in use until around 2013 or 2014, then dormant for some years and upgraded to current Bitcoin Core versions somewhere in 2020/2021 and emptied in 2021. That's probably not what you're looking for and I won't give it away anyway.

I might have other, likely unused, wallet.dat files I created, maybe in 2012. But I'm not sure if I haven't touched them with a more recent version of BitcoinGUI or Bitcoin Core when checking if they're really empty or not.

Can't you find what you're looking for in "recoverpy". This Python tool can search for file fragments and private keys on storage media, so in the tool's code there should be hints about data signatures that are scanned.

Old hard drive used to mine, transferred keys to a flash drive, flash drive wound up lost. Hard drive broken when opening up a decade or so later. Was able to get it recovered after trying 3 different facilities.
Yes. Have used a few programs so far, may need to repair, not sure yet.
Not sure exactly what you're asking. I'd assume the version or what I was using. This was 2009.
Thanks for the idea on recoverpy, I've tried a couple programs like that, but not that one yet!
If you don't mind checking and are willing to send something empty over, that would be much appreciated.


If you are dealing with an old device or one that has some data, it is best to stop using it and ask a data recovery specialist, create several copies of the file and then you can continue asking questions here.

If the wallet is very old, the wallet file may not be encrypted and you may be able to access the private key by opening that file and search for it, if you can access it you can import it into any SPV wallet.

Already done, images are distributed for safe keeping and in good hands. Thanks for the good advice, though.
Indeed.


Do you mean older version of "Bitcoin Core" (which called as "Bitcoin-Qt" or "Bitcoin) when you say "Pre-Core"? If yes, you could just download the older version and generate a new wallet file using it. You can use these links to obtain the older version,


For other version, you'll need to find it elsewhere or compile it from source code.

Yes just original Bitcoin. Thanks for the guidance.

Looking for anyone who has any super-old wallets where they stored keys and can provide file signatures from keys stored in hex/binary format.

Working on recovering some coin from that era and file signatures would be very helpful.

If anyone can provide them, will be happy to send some coin from the recovery if successful.

I'm looking for the oldest copy of core I can find. Looking for older than what's in the repo...

Does anyone have a really old copy laying around?
I don't have any copy of an oldest version of Bitcoin Core but there are

Thanks for guiding me in the right direction and the quick responses.

Hello,

I'm looking for the oldest copy of core I can find. Looking for older than what's in the repo...

Does anyone have a really old copy laying around?

Can i ask why you need it ? Smiley

Partially just for posterity and wanting to go through the code, but I'm making another post regarding trying to get ahold of file signatures which I need to get from wallets that were made back then and stored which I'm trying to recover. I was considering doing a replica early Bitcoin test-net and making new wallets in order to utilize the file signatures from those, but I wonder if these are truly unedited original source code in it's entirety or not.. Haven't really messed with it yet.

If anyone would be able to help with old key file signatures, I'd be happy to send some coin over if we're able to recover. Recently had an old, broken hard drive recovered that I mined a significant amount on way back at the beginning and socked away for it to appreciate. I had copied it to a flash drive as well, but that wound up lost and I've spent the last 3 years trying to get the correct hard drive recovered with multiple recovery facilities. Finally was able to get a good image, but so far no luck. Appears it was deleted or overwritten as I had stored it elsewhere and the drive was used for a bit after that.
