Sinbad Mixer: Mix Your BTC Quickly

Remembering or memorizing your seed phrase would never be recommended, it may be easy to remember 12 words in the first few days, weeks or months, but in years and with many other things that the brain accumulates as time passes, you can easily forget some words or the sequence. With good OPSEC nobody is going to find your seed phrase written on paper, just back it up properly. The brain is fragile, and if one stores 12 words or more in their head, then with just a brain disease or injury, their BTC could be gone, it is better and safer for it to be on paper and in two different locations.

I agree with that, sometimes it could be not only 12 but 24 words (BIP39), and it's pretty hard to remember constantly, even for a young age person. I would definitely not recommend just memorizing it and keeping it in your mind. As you said, you could even forget the sequence one day or get a brain injury that would make you forget it.

I mean, it would be extra for you if you remember it in your mind as 2FA (which is really good), but it's better for you to keep it safe somewhere, like on a piece of paper or by engraving it on steel or a stone that won't break, and hiding it in a place that only you can reach. Just think of it as your identity or your passport, or even more important than that if you have a lot of money in your wallet, because it can't be recovered.

My biggest recommendations are:

1. Not to save it on your PC or any device connected to the internet, that's a way too risky.
2. Store your seed phrase 2-3 times in different places and make sure it won't get damaged even in a disaster + (bonus if you have it memorized in your mind)
3. Don't leave any obvious hints about your seed phrase to any of your friends. However, it's probably a good idea to give a hint to at least 2 members of your family (in case you die) so your bitcoins won't be lost.

Edit:

This is another really secure way to protect your seed phrase posted by @fillippone, it's really cool. ~~> Securing Your Seed Phrase with Washers

Exactly, lol. I would rather prefer to remember my seed phrase than write it down and have all my money stolen at some point in the future. Or just sit on the piece of paper, trembling that someone might see it. It's all so troublesome. Why not just remember it? Its only 12 words.

And anyone who has a bad memory could use the 12 words to enter their wallet each and every day. After doing that exercise for a while, they would reach some point where their brains store their seed phrase in their long term memory.
The brain can fail you at anytime, unexpectedly, and your BTC may be gone just like that. A stroke can happen to anyone at anytime.
So is there really a 100% safe method? Not really.
Nothing is 100% safe, but there are methods that are safer than others, and with great additional operational security it can be as high as 99.9% safe.

It does not even have to be every day. You could enter your wallet through your seed phrase every few days. It would still commit itself to your memory after a while.

But you are still in danger of keyloggers and the sort... So is there really a 100% safe method? Not really.

But what if, you have 1,000 Bitcoins in your wallet, and you forget one word, JUST ONE WORD, and you have no copies of your seed phrase anywhere because "remembering 12 word is not that hard". You'll definitely know the true meaning of manual brute-forcing. Hahaha.

 Cool

OP, have both physical copies, and digital copies. Put the physical copy in a tightly sealed pack, and store it under lock+key in a safe. Encrypt the digital copy in a USB Drive and place it in nested directories, with each layer encrypted, and with different passwords.

If it's the last word, you are lucky, because it derives from the previous 11 haha! It's a joke, I totally agree that we should never rely on our memory! Our brain is extremely vulnerable.

Now after reading your post, i have two copies of my seed phrases.
Great job! Now the next task is to a figure out a second secure location to store your second back up. There is no point having two backs up if you store them in the same place (i.e. at home), since a single event such as a fire will wipe out both of them.

I have kept the two copies of the seed phrases at my home. Those copies are stored in different places but in the same home.
It's difficult to find a place other than my own home to store the seed phrases. Storing at some friend's or relative home in itself is a big risk. You just cannot trust anyone with your seed phrases.

Events like fire, earthquake or other natural disasters are very rare to happen and even if they happen, what is the guarantee that our lives will be safe  Huh

Hear me out guys.

Paper can be really fragile, and all it takes is a tear or water spill or defacing to deny you access to your BTC forever.

So, you should make a second copy of your seed phrase that is identical to the first, and store it on a different place from the first seed so that they both cannot go down together except in extreme circumstances like a natural disaster.

Personally, I have two backups in two different locations. In each location I maintain:

2x: {
         1 piece of paper with my seed phrase written upon it, in black ink.
          I have put the paper in a plastic card sleeve.
          I have put the sleeve in a plastic zip bag.
}

So I have in total 4 backups actually, but placed in two different places.

So, 2 places guard me against physical disaster on the specific place and 2 backups in each place guard me against physical damage on a specific piece of paper (which is highly unlikely).

Thoughts:
1. I know my system is ultra redundant, but I sleep well at night.
2. I maintain paper backups, so putting 2 of the aforementioned packages in a single place, requires less space than using other possible backup media.

Now i think this part is the most difficult when it comes to ones backup, for people who have relatives or family they can trust, they would just move one backup to the house of their relative, and keep one in their own home, people who also have two houses would store their second backup easily in their other home. But for people who have none of this, they may have no option but to have two backups in the same location.

Now i was thinking, for people who have no option but a single location, would having two different types of backup aid them, like having one paper backup and the other one engraved on a stainless steel, so if a situation of a fire outbreak happens, the first backup would surely be destroyed, but the second would not.

It's not hard, it's almost impossible to remember if you have more than one wallet. Also, Seed phrases are not limited to Bitcoin wallet, you may have Meta Mask for Ethereum and other wallets like trust wallet, etc too and it won't be easy to memorize each and every seed phrase.

You'd need to read it at least 20+ times before it starts to stick in your head.
Psychological pressure is enough for that, I remember that when there are remain five minutes to finish the exam, I forget all information.
It sounds funny, but that doesn't have to do with the pressure, it's called a the doorway effect, that there's every tendency a person will forget half of everything they've read once they pass through the door of an examination hall, compared to when they're in their reading room. It happens to almost every student, and humans will need to relax and think to remember what is been stored in the brain.

I guess that only happens when you study for it once. If you are indulging in the information continuously, there is a very low chance that you'll forget most of it. Not much of a problem for seed phrases as you should be etching those onto your mind before you start using them to store serious money.

A USB flash drive is not the worst method of a backup for your seed phrase, but i will still choose paper over it. USB flash drives have a lifespan, and even if it is not too short, it can become corrupted earlier on and you would lose data stored in it, which you can only recover most times with the help of a third party service, and that is not recommended because the data stored there is your seed phrase and it can be stolen by this third party.
~
All devices have the possibility of breaking down and that's a given, but it also depends on maintenance and how durable the device or USB flash drive is.

I found a few recommended USB Flash Drives that seem to have good initial security as well as resistance from extreme conditions.

It's not so much about the security as it is about the reliability of the device (it is easy to physically destroy it for instance).

Also if you watch tiktok, the chances of you remembering 12 words drops significantly (no joke).
The world is losing brain powers from watching most of these contents for long time on the internet that's why many are afraid of the institution of AI. Many people are losing their brain easily these days.

A sheet of aluminum Stainless Stell plate when can even be obtained at a cheap price at the building store.
Aluminum is a poor choice. As far as metals go, it has very low strength and durability, it is highly malleable, it has a melting point well below temperatures reached in an average house fire, and it is very prone to corrosion. It offers very little over just using paper.

You can easily pick up stainless steel at a hardware store. Use this instead.
You are right about this. It seems that I was wrong in the mention, it should be Stainless steel.

I have discussed about good materials to use as seed storage. And the choice that I think is good and resistant to rust and can withstand extreme temperatures is Stainless Stell 304 which is a type of Austenitic Made from several ingredients such as 16% Chromium and 7% Nickel and Nitrogen, which will make it have strength and resistance at high temperatures or low temperatures and resistant to corrosion.

There are several types of stainless steel with different resistance

Unfortunately, people not very wealthy rarely have to store amounts way bigger to what they hold on exchanges and other platforms. So storing their 2FA backup safely is usually as critical as protecting their cold wallet seed for them, and using an aluminum Stainless Stell plate is not suitable for that. For them usb drives or printed papers will always remain the only viable solution.
It is just an alternative or safer option. A sheet of aluminum Stainless Stell plate when can even be obtained at a cheap price at the building store.
Or using washers which is certainly easier and this method has been discussed by @fillippone

Securing Your Seed Phrase with Washers

You can use the Blockmit Washer Jig to stamp the washers with precision and easier.
https://www.cryptocloaks.com/product/blockmitjig/

Or if you want to save more money, you only need to stamp it manually.
All you need is Metal Stamps Letter & Number tools, a hammer, and Bolts.
You can get all those materials easily.


https://johnchow.com/how-to-make-your-own-crypto-steel-recovery-seed-backup/

USB Drives and Printing paper are just the initial solutions, but when someone needs a backup that is more durable in all conditions.
Then it is necessary to use washers or some other media. Security always comes first.

And USB drives today have many counterfeits that have poor quality materials and result in the performance of the USB drive (components break down faster).

So at some point in the future we will likely fork to some new quantum-resistant cryptography before quantum computers pose a serious risk. We don't need to make any decision regarding this for years or even decades, and indeed, making such decisions now would be a mistake given the entire field is in its infancy and any system we chose today would likely have been replaced by something else by the time it was actually relevant.
Every technology will follow the development of new technologies. Especially if quantum computers are really coming, then cryptography that is resistant to the threat of quantum computers will also be made.

As is currently the case with AI ChatGPT technology which is able to provide a lot of conveniences and also some negative impacts on the manual writing of an original forum user with AI writing or thinking, AI Approximation is presented so that it will inhibit all fraud that arises due to AI.

Quantum computers are not a threat if technological developments go hand in hand and they will be a great solution for future technological developments.
We are still in the early stages, that's very good.

Don't forget that in such a scenario then almost all the encryption currently used across the entire internet will similarly be broken, including everything to do with the fiat banking system.
Yes, it is undeniable, if quantum computers are present today and used commercially, nothing will be safe, all systems can be paralyzed easily, not just cryptography, but covering all security systems.



This life is an endless cycle of Problem -> Solution -> Problem -> Solution ∞
All will experience the cycle, but there will definitely be improvements to the solution that will be provided.
As with the type of seed phrase storage solution being discussed this time. There are various kinds of solutions and problems that arise.
But each solution has a different level.



A USB flash drive is not the worst method of a backup for your seed phrase, but i will still choose paper over it. USB flash drives have a lifespan, and even if it is not too short, it can become corrupted earlier on and you would lose data stored in it, which you can only recover most times with the help of a third party service, and that is not recommended because the data stored there is your seed phrase and it can be stolen by this third party.

I found a few recommended USB Flash Drives that seem to have good initial security as well as resistance from extreme conditions.

Corsair Flash Survivor Stealth

It seems to be a USB Flash Drive that is resistant to all conditions with a design that is specialized for extreme conditions.
The CNC-threaded Anodized Aluminum body is able to withstand 40Gs of shock and impact, and the rubber seal will make it survive underwater at a depth of 200m.

Apricorn Aegis Secure Key 3 NX

A dual-security USB Flash Drive that uses a PIN-based locking feature right from the drive. It uses 256-bit, real-time AES XTS Encryption for all file types, meaning that as soon as you transfer anything to the onboard storage, it's already locked behind a wall of military-grade protection (FIPS 140-2 level 3).

See the reference here: https://www.pcmag.com/picks/top-rated-usb-flash-drives

Make sure your USB flash drive is not connected to the internet regularly, and it must be encrypted and a strong password set up. Paper backup seems the best to me, but since you said you use 3 flash drives, i hope you have not kept all these backups in one location, if you have done so, you should consider separating it in different locations.
Don't make paper your best backup, upgrade to aluminum Stainless Stell plate material which is safer in all conditions and will not be damaged or faded.

Two is even too small if the person can write as many as he or she can let them do it. Because the two copies can also be misplaced or lost. So having more might save the disappointment and lost of coins. I have five copies in different places. I didn't keep them in one place, I heard one in my father's house, another in my mother's house, one is in my office and two are with me.
The two I kept with me are the original but the other ones, I changed one particular figure in all which I know it in my memory. And it is on the first later for all. That is the different between the ones that are with me and the other ones.
You can also go to parenting press or print it with a HP Laptop printer 🖨️ to print it and laminate it so that the laminating paper will become a water resistant to the seed paper.
It's interesting but how have you been able to change the first letter of your seed? Some words of the BIP39 dictionary are exactly the same except their first letters? If it's true, you are not afraid that the guy finding your seed could be aware of those special words, spot them in your seed and try to make the swap of the letters? Especially if your fake seed doesn't contain any transaction?
And if the modified words don't belong to the BIP39 wordlist, you're not afraid that the attacker could spot them instantly if he tries to enter them in a wallet? You don't think he could try and manage to find the original word?

If I forget, I'll ask my wife. And as I said above, I can at least look for a physical back up in places I am likely to store one. If you forget your seed phrase, then you are shit outta luck.
So, isn't it far more dangerous to entrust the location of your private keys to another person? Even if it's wife? Doesn't matter, the minute more than two people know a secret, it's no longer a secret.

I think it doesn't need further discussion, your way of doing this and my way of doing this, both have pros and cons and we highlighted it very well in favor of protecting our arguments. I think it will enlighten some people to read our opinions and choose whatever they think suits them. It was my point at some point too Cheesy
I love it, when people protect their opinions, the more holes they seek in opposite opinion and more positive sides they are looking for in their opinions. When both sides do that, then discussion gets more meaningful.

If in a few decades, a powerful enough quantum computer can break ECDLP, it will be a technological advance, but on the other hand, it will be quite crucial, because it doesn't take long to break or crack the ECDLP signature system.

Do not depend on your memory because memory can fail anyone at anytime. The best is to backup your seed phrase in two places. If you keep it in three different places, it makes it better.

Most people can have more than one wallet. Some people can have 2, 3 or more wallets, keeping their seed phrases offhand wouldn't be ideal.

it is kinda worrying leaving your seeds somewhere someone can find but for sure there are solutions. This is the real risk of crypto currencies.

It seems that I need to learn more about some notions of algorithms and about the ECDLP signature system.
The bottom line is that there is nothing to worry about for many years or even decades.

Out of all the various parts of bitcoin, the bit which is the most vulnerable to quantum computers (via Shor's algorithm) is the elliptic curve itself, which means an attacker being able to take a public key and calculate its corresponding private key. Reverse engineering from addresses (rather than from public keys), mining, and many other parts of the protocol are less vulnerable because they use various hashes, which are far more quantum resistant than the ECDLP.

So at some point in the future we will likely fork to some new quantum resistant cryptography before quantum computers pose a serious risk. We don't need to make any decision regarding this for years or even decades, and indeed, making such decisions now would be a mistake given the entire field is in its infancy and any system we chose today would likely have been replaced by something else by the time it was actually relevant.

One missing word from the seed is not too much of a problem, I think that finding even three words is feasible with today's technology in some reasonable time. As time goes on computers will become more and more powerful and some who have really messed up with their backup hope to be able to discover their treasure chest.

Of course, a lot of bad things can be avoided if we take some basic precautions, and one of the basic ones is to understand that only one backup represents a big risk, but even 2 or 3 in the same location in some cases will not help if it is about ordinary paper.


I was merely making a point that the inconvenience of thinking about brute-forcing a word isn't worth the stress that the user would be going through if a simple back-up would have made him/her avoid all of the stress.

Personally, as posted, I like both digital, and physical back-ups for both convenience and redundancy.

Like a Treasure that has some clues to find it.

But it becomes an old technology that has many mysteries to be solved, but in modern times like this the way it is done will certainly be different.
There are many secret places that can be used to store anything and they can only be accessed by the owner and the rightful heir.

Any pleasant past events or any events that are memorable will be easy to remember, but not with complicated codes or random numbers, it is very difficult for anyone when it has entered the years.

If yes, then I hope you got my point.
Of course. But as I pointed out in an older post which was quoted earlier in this thread, I am under no illusion that I could very easily forget such things through no fault of my own and with absolutely no warning. Anyone can have a stroke at any time. Anyone can simply trip and hit their head on the sidewalk at any time. Anyone can contract meningitis at any time. The number of possible ways your memory can be damaged cannot be counted. I don't like those odds, especially when it is so trivially easy to overcome them by simply writing your seed phrase on a piece of paper.

Memorizing isn't that hard or bad practice.
Only if you also have physical back ups. Relying only on your memory is very bad practice.
Be frank, aren't there some long poems that you learned so well in school that you still remember them word by word?
If yes, then I hope you got my point.

And if you get into crash or get a heart attack, develop dementia or something terrible happens, the first question is if you survive and the second question is, if you actually remember that you have bitcoins or in best case, where you saved your seeds.
You are more likely to remember where you physically put something than a list of words you just repeat to yourself over and over. And if you forget the location of your back up, you can at least look for it. If you forget your memorized seed phrase, your coins are gone.
-snip-
By the way, if you try to memorize 18 or 24 words, then you shouldn't trust your mind in this case because it's too much to properly remember for a long period of time. 12 words are fine!
12 words will also not be fine and you should not trust your mind completely. The human brain is indeed capable of remembering anything in the long run if it is trained, but the human brain also has an age. As we get older or enter the aging period the brain's ability will decrease slightly.
Senile dementia will be a problem if you have to remember 12 words without any copies.
If I am an old man with not so good memory, I wouldn't trust myself. Finally, everything comes down to what you are capable to handle. But guys, if you say that if you get stroke or heart attack or dementia or crush accident or fell from the mountain, etc, then I have a question, what makes you confident in remembering the secret place where you stored your keys? Let's be frank, in such extreme cases, our methods don't have any advantage. If you save your seeds in a place that's easy to reach for everyone, then you are not actually keeping your seeds safe and if you save it in a secret place that's hard to find for anyone and you experience extremely bad accident, then more likely you won't be able to recall that place and in extreme cases, you won't be able to even acknowledge that you had something saved. This applies to memorizing, if one is fucked, doesn't matter he/she memorizes or saves it in a secret safe place, the person is in trouble.

So, once again, I want to say that everything comes with a price!

Quantum computers that use Grover's algorithm in the case of breaking symmetric encryption algorithms such as AES (Advanced Encryption Standard) are only able to weaken their strength or reduce all possible encryption keys to half.
That's not accurate.

As I said above, Grover's algorithm allows a problem to be solved in the square root of n-time. Half of 2256 is 2255. Grover's algorithm reduces 2256 to the square root of 2256, which is 2128.

But in Bitcoin using the 256-bit ECDSA digital signature system, the possibility of encryption keys that can be done effectively Brute Force from 2256 to 2128.
If you are talking about solving the ECDLP, rather than brute forcing part of a seed phrase as above, then you are now talking about Shor's algorithm, not Grover's. Shor's runs in polylogarithmic time, and can factor a k bit number in k3 time. A sufficiently powerful quantum computer (again, decades away) could easily break the ECDLP.

Making more copies is risky too.
The best solution is to have a set up where compromise of one back up is insufficient to steal your coins, such as separate seed phrase and passphrase back ups, or a multi-sig. Make two copies of each part. That way you have redundancy against accidental loss as well as greater protection against theft.

Making more copies is risky too. A burglar might steal your home copy while you are not home... You may protect yourself from a natural disaster but then there will be other risks... On the other hand having only one copy is also risky because anything can happen to it. There isn't a foolproof easy solution to this problem imo. Physical paper wallets have their own risks, memorizing the seed words is also dangerous because dementia is a bitch... computers can get broken or get hacked if they are connected to the internet. Should you make 2 copies of your priv keys? Maybe. But I know for sure, you shouldn't make more than 2.
There is no easy solution, every choice will have risks and the risks will certainly vary.
Having more than one backup will be risky if the other backup is known by others, therefore securing all backups becomes the main focus.

Don't let one of the backups get out of your control. It is not easy to safeguard something valuable, especially when it is related to future investments that can only be opened with the key.

There are so many security alternatives that can be used as options, but look back at what risks can occur. Adjust to our needs and abilities as users.

Hear me out guys.

Paper can be really fragile, and all it takes is a tear or water spill or defacing to deny you access to your BTC forever.

So, you should make a second copy of your seed phrase that is identical to the first, and store it on a different place from the first seed so that they both cannot go down together except in extreme circumstances like a natural disaster.

Could be. A sufficiently powerful quantum computer running Grover's algorithm can perform a brute force search in O(√n) functions, rather than O(n) functions as a standard computer would. This means that a 2128 string could be brute forced in only 264 iterations. This is all dependent on very powerful quantum computers though, which are a long way off.
Quantum computers that use Grover's algorithm in the case of breaking symmetric encryption algorithms such as AES (Advanced Encryption Standard) are only able to weaken their strength or reduce all possible encryption keys to half.

In contrast, if a quantum computer solves an asymmetric encryption algorithm such as RSA, then a quantum computer can break it, especially for RSA-1024.

But in Bitcoin using the 256-bit ECDSA digital signature system, the possibility of encryption keys that can be done effectively Brute Force from 2256 to 2128.
So with the calculation capabilities of Quantum Computing and Grover's algorithm, it takes 2.6 x 1032 years.

Currently, it is still very unlikely to be used commercially, Quantum Computers are also tagged with very expensive prices such as D-Wave Systems products and some special licenses are needed because they are only used by a few large companies and research institutions.

I think people get too hung up on metal seed phrase storage, and it can actually lead to poor practices. Because of the expense of such devices, many people will just buy a single device and that will be their only back up. Only having one back up is a very risky situation, especially if that one back up is stored at home alongside the device(s) your wallet(s) are installed on. Two pieces of paper in separate geographical locations is safer (not to mention cheaper and easier) than a single metal back up.
Expensive because the materials used also support security (depending on how many assets are stored) it doesn't matter if the metal reserve costs hundreds of dollars but is used to store assets worth millions of dollars, it is not easily damaged and even withstands any conditions.

Actually, this is only optional for advanced security. Using standard security or more affordable ways is also fine, as long as the backup is in good condition.
Having 2 or more backups will help, but all of them must be secure and have full control.

Two is even too small if the person can write as many as he or she can let them do it. Because the two copies can also be misplaced or lost. So having more might save the disappointment and lost of coins. I have five copies in different places. I didn't keep them in one place, I heard one in my father's house, another in my mother's house, one is in my office and two are with me.
The two I kept with me are the original but the other ones, I changed one particular figure in all which I know it in my memory. And it is on the first later for all. That is the different between the ones that are with me and the other ones.

By the way, if you try to memorize 18 or 24 words, then you shouldn't trust your mind in this case because it's too much to properly remember for a long period of time. 12 words are fine!
12 words will also not be fine and you should not trust your mind completely. The human brain is indeed capable of remembering anything in the long run if it is trained, but the human brain also has an age. As we get older or enter the aging period the brain's ability will decrease slightly.
Senile dementia will be a problem if you have to remember 12 words without any copies.

You are more likely to remember where you physically put something than a list of words you just repeat to yourself over and over. And if you forget the location of your back up, you can at least look for it. If you forget your memorized seed phrase, your coins are gone.
That would be a serious problem. No library list will be remembered if some phrases are forgotten. The brain's ability will continue to decline.
Instead of risking losing it without any trace, it is better to record it in physical form and store it in a safe place.
Or use a "Timer Capsule" which will protect any document well, is fire and water-resistant, and can withstand any condition.

The choice of material or container used to store documents can choose Stainless material which is more sturdy and rust or corrosion-resistant.

One missing word from the seed is not too much of a problem, I think that finding even three words is feasible with today's technology in some reasonable time. As time goes on computers will become more and more powerful and some who have really messed up with their backup hope to be able to discover their treasure chest.

Of course, a lot of bad things can be avoided if we take some basic precautions, and one of the basic ones is to understand that only one backup represents a big risk, but even 2 or 3 in the same location in some cases will not help if it is about ordinary paper.

is remembering 12 words that hard?

It's not.. until it is. Just imagine a stroke, or a (motor)bike crash, or many other things the can happen to you.
Plus, mind is a very strange thing. In a year or two you will be certain the 5th word in your seed is "about" and in reality it was always "above".
So no. It's not difficult to keep in mind 12 words for a while. But the longer that while is, the more chances for something to go wrong.

Memorizing isn't that hard or bad practice. If you try to memorize seed phrases every day for multiple times in a one year timeframe (keep seeds for some months or one year), if you write them down very often and then burn that paper all the time for security purpose, or if you write them down on keyboard (unplugged from computer), then you not only depend on your just memory alone, you also seal it deep inside your muscle-brain memory, you touch the keyboard and your hand know what to write.

By the way, if you try to memorize 18 or 24 words, then you shouldn't trust your mind in this case because it's too much to properly remember for a long period of time. 12 words are fine!

In my school, emphasis was on memorizing of information, probably that played its role into making it easier to memorize things.

especially if write one of the letters wrongly.
I can relate to this experience, i have a friend who thought writing one word out of his seed phrase was a good way to protect it if someone found the seed phrase, but it is only good until you yourself forget correctly what the last word is, and lock yourself out of your funds. What my friend did was that he would write 12 words down, but one is incorrect, then he would try to memorize the correct word that was omitted, and that which is incorrectly included, so whenever he wants to import his wallet, he would eliminate the incorrect word and replcace it with the correct word he had in his memory, at the time i thought this was a good thing to do.

After close to a year, my friend couldn't remember the correct word he committed to his memory, it was surprising and i can even call it a traumatic experience for him because he kept trying and thinking, he was successful in less that 24 hours though, but it was a risky event, imagine if one can forget just one word, what about 12 words. Memorising seed phrases or trying to be too clever while backing it up is so risky, just do the simple things and have more than one backup.

Make 3 seed backups in steel washers (or titanium).
titanium is most expensive, you can try to buy cheaper steel SS304, it's enough save with house fire temperature, and I tested in my journal research.

Beberapa bulan lalu saya membeli lembaran plat metal berjenis SS304 yang banyak dipakai untuk menyimpan 12/24 word mnemonic seed oleh beberapa perusahaan terkenal crypto.

Karena kalau beli langsung jadi itu mahal, maka juga berinisiatif membuat sendiri dengan membeli lembaran plat SS304 secara online. Murah, tidak sampai 100 ribu, dan masih bisa di potong beberapa bagian sehingga masih sisa banyak untuk nyimpan yang lain.

Dan kebetulan juga sekarang ini lagi ada kerjaan workshop dan ada alat untuk melakukan tempering logam, maka saya berinisiatif untuk melakukan pengujian sendiri terhadap ketahanan panas plat SS304 yang saya beli tempo hari. Biar nanti tidak ragu, karena plat SS304 yang saya beli tersebut bisa jadi bukan yang sebenarnya, sehingga kalau terjadi sesuatu misalnya kebakaran, meleleh atau tidak kuat menahan panas.

1. Plat saya potong sedikit (hanya sebagai spesimen), berukuran Panjang 65mm, lebar 33mm dan tebal 3mm. lalu saya stamping.



2. bersiap melakukan pemanasan atau furnace dengan menggunakan alat ber-merk Nabertherm asal jerman.
ketika sudah mencapai suhu 900° C, plat saya masukan dan menunggu 10 menit



3. Setelah itu saya keluarkan dan dengan bantuan teman untuk menyiramnya dengan air (mungkin lebih baik dibiarkan begitu saja tanpa menyiram dengan air)



4. Dan, gambar di bawah adalah penampakan setelah dipanaskan dan tempering, tampak tidak ada perubahan, tulisan masih dapat terbaca walau sedikit menghitam



5. Untuk menghilangkan kehitaman, saya berinisiatif mengamplasnya, dan tulisan sudah nampak terang terbaca



Jadi kesimpulannya, Plat SS304 (memang betul-betul SS304 asli) yang saya beli di toko online tersebut cukup kuat menahan panas di suhu 900° C selama 10 menit. Karena pada beberapa kejadian, suhu 900 tersebut adalah suhu kebakaran rumah tertinggi, dan 10 menit itu adalah waktu tercepat jika ada mobil pemadam yang menyiramnya dengan air.

Mungkin ini bisa dijadikan patokan dan dasar buat kalian untuk mulai menyimpan word mnemonic seed di logam berjenis SS304 tersebut.




a. Dasar saya ambil suhu 900 [1].

[1]. https://www.cnnindonesia.com/nasional/20201023194626-12-562173/suhu-api-kebakaran-kejagung-capai-900-derajat-celsius

b. sebenarnya respon time pemadam kebakaran datang itu 15 menit [2]. namun karena itu terpenitng dalam hidup saya, dapat dipastikan jika memang terjadi, plat SS304 tersebut akan saya sangat perhatikan, mungkin jika (amit-amit) terjadi, itu dulu yang diselamatkan dari dalam brangkas. Jadi 10 menit itu maksimal, bisa jadi kurang karena yakin sih safenya berlapis.

[2]. https://sippn.menpan.go.id/pelayanan-publik/sulawesi-selatan/kabupaten-soppeng/layanan-response-time-penanggulangan-kejadian-kebakaran-

c. kalau ragu (misal beli online) plat misal ss304, titanium, dsb Asli,  baiknya di uji komposisi di lab, namun ya itu mahal, tidak sebanding dengan beli asli yang bersertifikat. Saya melakukan manual pengujian di atas karena memang ada kesempatan aja, kalau pun memang kepepet dan ragu, bisa diuji coba di atas kompor gas, tapi musti izin dulu sama emak.

Very hard than you can imagine. Haven't you heard of memory lose before? Brain dimentia and so on? Yes, we all know the danger of writing seed phrases on a tangible materials but cramming it is not the best way neither. Writing on a paper should be out of options completely as it is not secure at all. In my opinion, metal plate has covered me and my seed phrase already.

Look for a sizeable flat metal plate, a nail or needle and hammer to print your seed phrases on the metal by making it in form of hole. It actually takes a little bit time but it is more safer and resistant to both fire and water. Ensure to save it in a dry, clean and private place to avoid hole blockage.

This doesn’t still eliminate the risk entirely because if it is save in a place where no one could actually get to then if there’s is a case of serious brain trauma like amnesia where it is hard to remember past events then it will also make it hard to find where it is stored. So no matter how hard it is to trust people there should be a family member that one needs to share one of the storage places with. As this could also be vital in recovering this funds should the owner dies

Paper can be really fragile, and all it takes is a tear or water spill or defacing to deny you access to your BTC forever.

So, you should make a second copy of your seed phrase that is identical to the first, and store it on a different place from the first seed so that they both cannot go down together except in extreme circumstances like a natural disaster.
Although it doesn't sound like much of a novelty, it is quite an important suggestion to make in terms of greater security.
The second seed pharse backup besides being stored on paper, it is a good idea to prepare another place to store such as in a metal mold that can withstand a fire.

The problem of creating more than one wallet seed with earthquakes is in distributing them, you will be forced to keep one of them away from you or your home and perhaps your geographical area, which increases the risk that someone else will be able to know it.

There are multiple ways to encrypt/secure your seed backups so they are not readable even if someone finds them in the open at a different location from yours.
There are ways to encrypt a seed in a way that you could show it to people, they would think it's a real seed, but they wouldn't be able to get to your coins.
There are also ways to encrypt a seed in a way that you could show it to people and they wouldn't even recognise it as a seed, so they wouldn't be able to get to your coins.

For example: Simple cipher (Youtube link with timestamp), Passphrase, XOR, Shamir secret sharing, Multisig, and more.

Make 3 seed backups in steel washers (or titanium). And ideally encrypt them with a simple cipher (easiest and fastest) or use a passphrase and store that separately.

Earthquake proof, Low cost, affordable, easily scalable, indestructible, fireproof 1400°C (a house fire is around 1100°C), waterproof, corrosion proof, shock proof, offline cold wallet, seed or passphrase backup.

Your proposal is not new and this issue has been discussed many times, but it is better to repeat this several times in order to avoid unexpected losses in the future.

Paper is a fragile carrier of information and you can't argue here. Then maybe use other, more reliable ones? Metal, plastic. Plastic? I don't remember anyone suggesting this option. Sure, it's not the best way, but it might be better than paper. Although it can't withstand fire in the same way, neither the tears of bitcoiners nor water can spoil the text. Easy to apply: heat iron dies and press against a piece of plastic.


Two copies may not be enough. At a minimum, you should start with 3 pieces.
I see it like this: 1 carrier of seed phrases on paper in easy accessibility, which is not a pity to lose. 2 media on plastic, for example, stored more securely. 3 carrier - on metal and hidden in the most reliable way in the most inaccessible place and being the very last reserve.

So, you should make a second copy of your seed phrase that is identical to the first, and store it on a different place from the first seed so that they both cannot go down together except in extreme circumstances like a natural disaster.
I wouldn't stop at only two copies, because three is better than two.
Adding one or more passphrase is also a good suggestions, and multisig setup is even better.

it is kinda worrying leaving your seeds somewhere someone can find but for sure there are solutions. This is the real risk of crypto currencies.
Your brain is much worse place to keep anything important, especially something like seed words.
This is the real risk of human body experience, and you wouldn't be the first to lose coins for trusting your brain so much.

If you are worrying about your seed phrase and you do not want anyone to steal your coins, you can add passphrase to it. If you add passphrase, you are safe but you have to let the passphrase to be strong. Eight to ten or more characters that consists of alphabets, numbers and characters like .,@ should be enough.

is remembering 12 words that hard?
Do not depend on your memory because memory can fail anyone at anytime. The best is to backup your seed phrase in two places. If you keep it in three different places, it makes it better.

Most people can have more than one wallet. Some people can have 2, 3 or more wallets, keeping their seed phrases offhand wouldn't be ideal.

Paper can be really fragile, and all it takes is a tear or water spill or defacing to deny you access to your BTC forever.

Well, this advice is far from new. But indeed, it's good to remind people now and then about it (I would have been expecting this in B&H though).

It's not.. until it is. Just imagine a stroke, or a (motor)bike crash, or many other things the can happen to you.
Plus, mind is a very strange thing. In a year or two you will be certain the 5th word in your seed is "about" and in reality it was always "above".
So no. It's not difficult to keep in mind 12 words for a while. But the longer that while is, the more chances for something to go wrong.
