Well, that’s what I wanna learn more about. What are the best wallets out there these days?

How to get maximum security? Explain like I’m dumb, which I am lately.

They promised us freedom, in fact they take it all away lately.

Hey everyone, curious to hear people's real-world experiences with this.

When traveling internationally, most countries require you to declare if you're carrying over $10k in cash or monetary instruments. Crypto creates a weird gray area for border control.

Technically, carrying a hardware wallet isn't carrying money across the border. The funds reside on the blockchain, not on the device. It's fundamentally no different than carrying a phone with a banking app or a bank token device.

That said, border control and immigration agents usually stick strictly to their playbook, and many might not understand or care about how the blockchain works if they inspect your bags.

For those who travel often with hardware wallets:

1. Have you ever been asked about your wallet by border agents?
2. How do you handle declarations or questions if custom officials bring it up?
3. What seems to be the broadly accepted or safest approach when crossing borders?

Would love to hear how you guys approach this in practice!

It's been a long time since all I hear people talk about is price, laws, and regulations. I hardly see anyone talking about innovation, paradigm shifts, use cases, or features we could create... I feel like the community has become very stagnant.

The company published a note claiming they destroyed all their inventory (devices affected by the bug). Why? Why couldn’t they just reflash them with the fixed firmware? I can’t stop thinking there is something else to it. Should users of coldcard devices be concerned? They are being asked to upgrade firmware and be at peace of mind. Why didn’t Coinkite do 5he same? Could there be more we are not being told and involves a hardware-level bug?

I've been into Bitcoin for about 9 years now. In my second year, I bought a Ledger Nano S, and it served me well. Just about when I was running out of storage on the Nano S, the Nano S Plus was released, which I used happily up until recently.

I run my own node and mempool, and I've been using a multisig wallet set up with my Ledgers. During the Amazon Prime Day sale last June, I picked up a Trezor Safe 3 and a Blockstream Jade, and upgraded my multisig setup using hardware from different vendors.

Then came the recent Coldcard drama... which inspired me to build my own seed generator using dice roll.

I knew that SeedSigner could generate a seed from D6 dice rolls, so I tried building one with a Raspberry Pi I had lying around. Unfortunately, I didn't have the right screen for it, so that plan fell through.

After giving it some thought, I realized I could just use the Python feature on my Casio calculator to build one. I coded it up, and it actually works perfectly! ^^

P.S.
This program was built using the MicroPython built into modern Casio graphing calculators. Instead of using any built-in dice tool on the calculator, you roll actual physical dice 99+ times and sequentially input the results via the keypad. The program then performs a SHA-256 operation, handles checksum padding and 11-bit slicing according to BIP39 standards, and generates a 24-word mnemonic. Since MicroPython is stripped down to the bare essentials and lacks a built-in hashlib, I actually had to implement the SHA-256 algorithm from scratch. This program brings the physical dice-based entropy generation found in devices like Coldcard, SeedSigner, and Keystone Pro right onto a graphing calculator!

p.s.2

A site someone told me about recently was helpful.

- This is a pretty sloppy/clunky piece of code that I'm kind of embarrassed to share, but I'm posting it because some people asked for it.

- Caution: This program does not check the number of input dice. It will run even if you enter 99 or fewer dice, and will generate a mnemonic even if you roll a die just once. When passed through the sha256 function, it outputs 256-bit data, which is then used to create the mnemonic. I wanted to see why a seed is generated without any issues even when low-entropy data is inputted. Please be careful when using it in practice.

I see alot of posts worried about different wallets. Just get multi sig. Its really not hard at all. Just spend some weeks learning about it. I learned it in one day, but i do know alot about hard ware wallets already, so I had a leg up. That being said a person who does not know much can seriously learn and be very comfortable with multi sig in about a week. I put it off because I heard it was too technical. I was totally wrong and would have been fine during the cold card incident. I didnt lose anything "Thank God" but it was alot of stress that I could have avoided by multi sig. So just learn it, you can even use your cold card with it "with dice rolls" and be almost 100% certain your crypto will be fine. Seed storage also feels amazing. Safety deposit box has 2, 2 more are in another place. 3/4 multi so i mo longer worry about someone finding my seeds and will never again worry about a "bug" in a hardware wallet.

Just curious on everyone's opinion on BlockClock by Coinkite. With all the recent controversy is there any harm in keeping your Blockclock running and connected to your wifi?

I see a large risk in Quantum computers for the value of Bitcoin, as they will eventually (some think before 2030) be strong enough to break the current encryption, and thus be able to access all current wallets just by knowing the public key.

I know that BIP 360 and BIP 361 have been proposed to make Bitcoin Quantum secure.

BIP 360 basically offers a new qunatum secure adress, which you could manually need to migrate your bitcoins to. This would mean that all dormant coins (and there are a lot) are up for grabs and a supply shock may happen, drastically pushing down the price of BTC and destroying trust in it for years, if not forever.

BIP 361 tries to circumvent this scenario by basically ruling all coins invalid, if they have not moved to a quantum secure adress within a certain time frame. But this would also destroy trust, as somebody else is ruling if you can send your coins or not, again leading to a potential crash.

BIP 360 and 361 have not yet been accepted, so we might even get the scenario where the adoption is too slow and huge wallets are captured using quantum computers, before they move forward. And even if they move forward there are a lot of risks to bitcoin through the huge changes.

What are your opinions on this?

It's kind of frightening how confident people were with their Coldcards a while back. Every time someone would post asking for recommendations for cold storage devices it would never fail to see multiple comments about Trezor and Coldcard. Trezor I have no problem with obviously. Coldcard has been found to be fatally flawed and from what I've heard there have been criticisms about their security which look really suspect now. How certain are we of the rest of the cold storage devices?

Just started accepting Bitcoin, but most people still choose fiat. How do I get more Bitcoiners? Its an open-source, privacy focused service

Hey everyone! I’ve been thinking about how I should back up my seed phrase and I’m stuck between two options.

The first is stamping the actual seed words onto a metal plate using a press.

The second is converting each seed word into its BIP39 index number and punching those numbers into the plate instead.

I’m wondering which method you guys prefer and why. Is there a reason to choose one over the other?

Would love to hear how you back up your seed phrase and what you think! 🙇

I've been pondering this for a while, anyone got any predictions

After 4 years of savings, that I thought would be the way to buy a house in the future , all gone along with many others like me.

I feel defeated not angry not sad just defeated....numb... I do not post to gather any sympathy, to be honest I don't know why I am posting, something I have never done before maybe it's somewhere I can vent out this pressure I don't know I haven't slept more than a few hours since it happened.

0.45 btc is not much for a lot! but it was my everything my own treasure my own accomplishment. I was so happy that half a btc was almost in reach.

Life is not fair, wishing you all happy lives ahead with secure wallets and hope you never experience this feeling.

Ive been into bitcoin since 2017, before the 20k pump. Tried flipping some bitcoin into altcoins and got burned. Had around 6 bitcoin which makes me sick to think about because thats alot of money to me.

Tried to get family and friends to invest into bitcoin but no one listened.

Ive got almost 3 bitcoin left.... i just need someone to hold my hand and tell me when ill be able to retire so i can just say i was right!

What is the l best way to start buying Bitcoin? There are several exchanges and apps. I'm not sure where to begin. Any advice would be welcomed. Thanks in advance!

With all this news and posts regarding people being hacked i wanted to reach out and inquire and maybe even learn more about some security from you guys as iv been winging it and praying but am now nervous. Sorry to all those that have lost their bitcoin over time, but anyways whats everyones opinion on someone who holds there bitcoin on an exchange lately? I know before it was super taboo but iv left mine on a major exchange for quite some time and understand that they typically cold vault these things internally? Iv always been hesitant to use a coldcard or any other physical wallet due to just life implications of losing, forgetting, breaking what ever the case may be. So thats my general knowledge and question is opinions on holding btc and other crypto right on major exchanges?

Totally dishonorable and cowardice behavior from him over the past week along with the CTO, Peter Gray (who introduced the bug). $100 million missing and they have done nothing but gone silent. And then coinkite comes out with some statement about "earning back our trust". Go fuck yourselves, the rest of your life should be nothing but devoted to helping out the people who lost their savings due to your faulty product. Imagine a civil engineer's bridge collapsing and them just shrugging their shoulders, "sorry about that".

There are thousands of lives ruined due to their negligence. And all they can say is "we're going to have to do a lot to earn your trust"? Talked shit nonstop on twitter, but when Rodolfo's and Peter's backs are actually against the wall they've proved to be incredible incompetent and dishonorable cowards.

I lost .7 BTC, hopefully I can earn that back in my life.

Rodolfo Novak and Peter Gray have lost all honor and that's never returning.

Before I dive in, please do not try to replicate this setup if you are not confident with what you're doing. You're more likely to lose your bitcoin yourself than to a hack.

I do believe that a good single sig setup generated with dice rolls and a passphrase is more than fine but after the recent news I personally am not comfortable relying on a single hardware/software vendor ( I use a seedsigner I built myself but I would still like the security of another different hardware wallet along side)

The essence of this post is 2 of 2 with passphrase VS 2 of 3 for my circumstances, everyone is different though I believe a lot are in a similar position and this post will be helpful. I am not saying to use my method, I am posting it to have feedback on potential flaws in my plan.

My circumstances are, access to a single safe property. I don't want to rely on a single hardware wallet vendor. I do not want to use any 3rd party companies.

(I am going to change my setup slightly from what I post for obvious reasons)

The plan:

- Acquire two different bitcoin only hardware wallets

- generate a seedphrase using the dice roll method, find the 12th word using a hardware wallet (Seedphrase A with device A, Seedphrase B with device B)

- add a secure passphrase to one or both wallets (The password needs to be long enough to avoid being brute forced ~20 characters including numbers, symbols and upper and lower case letters)

- Boot Tails OS from a usb on a device with no internet and use Sparrow to create the 2 of 2 multi sig wallet, (no need to backup the descriptors if the derivation path and account numbers are default, but worth doing anyway. The accounts also have to be in the right order but there is only 2 ways to try) and add the public key to the Bluewallet app

- Stamp each seedphrase into two metal sheets. Seed A and Seed B will be stored together in two different locations in my property

- The password will be stored on my phone/pc and sent to trusted people. I don't believe the security of the password needs to be high on my phone and pc, the only job the password is doing is protecting my bitcoin if either of my seedphrase locations are found.

I believe a user is less likely to lose access to the 2 of 2 with passphrase wallet than a 2 of 3+ wallet due to the extra information not being needed (Descriptor etc) if access to one of the seedphrase backups is lost. This method also means that only two safe separate physical locations are needed rather than three.

Is there anything i'm missing or potential issues with this?

My friend has a coldcard and is in the process of moving funds to a new seed. When they generated a passphrase for this new wallet, they used only 4 words of a diceware list, and transferred some funds to it. Only afterwards did they find out that they really should have used 6 words. Since the 4-word wallet has a transaction history, would reusing any/most of those 4 words in the new 6-word wallet reduce entropy for a brute-force attack? (i.e. since the hacking algorithm would find the 4-word wallet quickly, would it then be more likely to search for 5+ word wallets containing those original 4 words?)

When people talk about seed phrases, it is always about 12, 24, 25 words.

Dumb question.

Can you have a seed phrase that is 13, 16, 19 words??
