That's not entirely accurate: The coins that were already in the wallet before encryping it are still there, also in the backup. But the moment you use a new receiving address, or create a transaction which sends funds to a change change, those aren't in the old backup anymore.

Using coin control would have prevented it:
If your wallet doesn't allow manual coin control or manual fees: stop using that wallet and switch to a decent one. Take your seed or private key and import it. For now, all you can do is wait until your transaction is dropped. If your current wallet keeps broadcasting it, that may take a very long time.

Bitcoin Core doesn't use unconfirmed inputs from third parties.

There's not much to sell that way. The etched ones are good looking, the benefit from bare steel is that the seller has no idea you own Bitcoin.

I like it If it's not too close together: 3 dots in one square and 2 dots in the next square can get confusing.

Editing my text from more than a year ago failed slightly. It's fixed now.

My other seed backup is burried at +34° 59′ 20″, -106° 36′ 52″.

This seems like an overly complicated method with many chances of making a mistake, and no benefits at all. It's not as if you can print the colors and find back the exact HEX number later.

It reminds me of another project I started more than a year ago: "100 dots" ! I never completed it (due to the lack of clean sheet metal), but it's time to post it

After reading n0nce's Steel Washer Backup jig (customisable), Securing Your Seed Phrase with Washers, Stainless steel Bitcoin Recovery Seed Plate, m2017's post and ColorSEED Or how to simply hide your seed phrase, I think it's time to post an idea I've had for a while. I came up with a combination that doesn't require a 3D-printer or laser engraving. Just a normal printer is enough.

For security:

Printing on paper and transparent sheets
You may need to adjust the printer setting. There are 2 types of transparent sheets, either for laser printers or for ink jets.

Template

Tape the paper sheet on a metal plate, get your center punch, and hammer the first 4 characters of each seed word with one dot per character. Then hammer 4 more dots in the red "oo" for alignment.
Remove and burn the paper sheet.
The size isn't perfect, it might be too small, but I don't want 24 seed words to take up a very large sheet of metal either. Maybe someone with better graphics skills than me can improve this.
Using exact 5 mm squares should make it possible to decipher the dots using only a ruler and a pencil, without printing on a transparent sheet. But that would make the required metal sheet size at least 13x24 cm for just 12 words. With accurate measuring, it should still be possible to decipher the dots without printing again.

100 dots
For 24 seed words, you'll end up with exactly 100 dots.

50 dots
For 12 seed words, use only "o" instead of "oo" just because 52 dots sounds less nice

Deciphering
Tape the transparent sheet at the right location, and read back the seed words.
With accurate measuring, it should be possible to decipher the dots without transparent sheet.

Hiding in plain sight
Who's going to suspect a metal plate with "random" holes to hold your money?

Do I dare use it?
I haven't tested this yet (due to the lack of clean sheet metal), and wouldn't use it as the only backup for real funds.

I know what it says, my point is it's a weird thing to see when I was hoping to see my transaction history.

What if you're a Newbie, got this wallet recommended, bought your first Bitcoin, and then the wallet tells you "sell"! I'm not sure yet if I'll be recommending this wallet.

I checked modlog after reading his post yesterday, and he had one topic and one post deleted. That's just from the last 7 days. For some reason he thinks those 2 PMs he received about it are meaningless. He's now on my Ignore list. The forum is nicer without reading worthless posts.

I now have 4 coins in Unstoppable Wallet, and discovered the Analytics tab. All 4 coins show exactly the same:
I've never seen a crypto wallet that basically tells me to give up on crypto

The Wallet is separate from the Transactions. I'd expect to see all Transactions "under" each coin, instead of on a separate tab where I either see all coins, or have to select one again.
All in all there are some design choices in Unstoppable Wallet that I would not have made myself.

This works the way you'd expect it to work The Letter of Guarantee doesn't mention anything about an amount, and the transaction page shows this:

I wouldn't call it "epic". More like it destroyed lives.
Don't go down that road. Using the Ignore button and moving on is much better for something as unimportant as an internet forum.

Lol.

Mainly his own, up to the point that the forum contributed to a stroke. Ignoring people is so much better.

May I remind you Finding spam and scams by keyword exists?

@Mods: Why isn't this guy banned yet? BPIP shows 54 deleted posts, AI chatbot spam is plagiarism by definition, plagiarism isn't allowed. So why isn't he banned?
It takes no effort to create those posts, but it's a tremendous waste of time having to read through those shitposts and report them. If one report means the user gets banned, at least it feels like it's worth the effort of reporting them. If nothing happens after 54 deleted posts, what's going to happen to the Tech boards?

I don't easily install software on phones, so I won't try it. But I must admit it sounds more promising than I initially expected.

Since HASH160 keeps coming up, I'll link World's fastest and simplest block parser for those who (only) need all HASH160 here. This is for all addresses ever used though.

I often use sort on large data sets, and can recommend to change the sort command to sort -u -S60% (assuming you have at least 60% of your RAM available). This largely reduces the need to write /tmp-files. Without this, sort uses only about 0.1% of the system's memory.
Depending on how big the final list is, this may or may not matter for performance.

I confirm I am very curious what this is all about It's like a riddle, and I love riddles but hate not knowing the answer

The Dutch company BitKassa offers something similar, I mainly know them from Arnhem BTCitcoincity. They've been around for years, but the statistics don't show much growth.

It would be cool if you can pull it off though, I'd love to see more shops accept Bitcoin LN.

You should post this on the Services board.

It sounds like you're planning to create a custodial wallet. That goes against everything Bitcoin stands for, and handing over private keys to someone else is the opposite of "security".

Whatever you're sending, it's not Bitcoin. Unless you're sending funded private keys, but that would be terribly insecure.

There are no "single-use addresses" in Bitcoin. You can choose to use each address only once though. And transactions can still be linked on-chain, even if you use each address only once.

"Social recovery" is terribly risky. Backup your private key or seed phrase, and be your own bank. That's how you backup Bitcoin.

Why didn't you start with this? I have a really hard time believing you can do non-custodial social recoveries, so please start by explaining the technical details.

Which projects? Please provide evidence.

The digital equivalent of putting your fingers in your ears and closing your eyes.
