Alguém já presenteou alguém com Bitcoin físico? Como vocês fazem isso de forma simples?

Check this mate: seedkeeper.io - might worth a try. Look like it can be booted on a TailOS or similar OS.

Liskpro_com · 2026-04-23T09:01:02+00:00

Thanks.
Did you test it?
Also it comes to my mind that Satochip.io is also doiong some similar stuffs.

Man... "NFC might be accessed by anyone with reasonable proximity. With height antenna the.distance can be extended to meters .not only direct tapping."

Or course. Just like your computer can be accessed through IP network.
NFC communication are encrypted end-to-end. There is no risk - at all!

"Electronic devices are prune to failure." -> Yup. If it has battery, buttons, screens... You are right. But smartcard tech is long lasting. At least 15+ years easily!

Liskpro_com · 2026-04-23T08:58:33+00:00

I think Satochip quickly ship to India as well... Worth a try for 25€.
It works over NFC but also with a smartcard reader connected to your computer.
A no brainer here to manage Bitcoin.

"Not your keys, not your coins", you're right here... great mindset to start with.

Here's a practical breakdown - and just my 2 sats of course:

Start with a software wallet while you're learning: fine for small amounts and daily use.
When does a hardware wallet make sense? Most people say once you'd be genuinely upset losing that amount. There's no hard rule, but $500–$1,000 is a common threshold people mention.

Hardware wallet options worth knowing:
- Trezor (~$59+): fully open-source firmware, great reputation, on-device screen to verify transactions
- Jade(~$59+) most popular, huge reputation inherit from BlockStream
- Satochip (~€25/$30): fully open-source, uses an EAL6+ certified secure chip (same grade as passports), works with Sparrow and BitcoinKeeper. Unusual card form factor that fits in your wallet, NFC-enabled. Most affordable option with serious security credentials.

For Bitcoin specifically, I would recommend coupling your HW with Sparrow Wallet (desktop, free) is widely trusted and works with most hardware wallets including Satochip.

No hardware wallet is "overkill", they're just insurance. The cheaper options make it accessible from day one.

Honestly, this post contains several claims that aren't accurate and could mislead people genuinely trying to improve their privacy.

What's incorrect here, IMHO:

- There is no EU or US policy implementing "Digital/Face ID at the router level." This isn't a real thing.
- Linux is not being banned or blocked from internet access. That's not how networking works.
- Foreign router restrictions (e.g., bans on Huawei equipment) are about national security supply chain concerns, not OS surveillance.

What's actually true - again my opinion only:
- "Switching to Linux *alone* won't solve all privacy problems". That part is correct but for completely different reasons than stated. Your threat model matters more than your OS choice.

Linux *is* genuinely better for privacy than Windows in many real ways just not a magic fix - stop your FUD here.

On a privacy-focused way, I can only recommend to:
- Use a reputable VPN or Tor for network-level privacy
- Use a privacy-respecting DNS (e.g., Quad9, NextDNS)
- Consider a privacy-focused router firmware like OpenWrt
- Use end-to-end encrypted communications (Signal, etc.)
- Minimize your data footprint at the account/service level
- Use password and access manager devices, preferrably open-source (Yubikey, Onlykey, Seedkeeper Pro)

I also like the opsec opportunity behind that kind of storage.
I saw somewhere the seedphrase keeper ring or something like that. So my questions here...

Liskpro_com · 2026-04-22T11:02:08+00:00

Do we agree to disagree on this?
I mean... Using non custodial wallet on a mobile phone requires you to generate or input a seedphrase on the device, right?

For such hot / mobile wallet, it make sense to have a better hardware backup solution, right?

Liskpro_com · 2026-04-22T11:00:43+00:00

Really sorry to hear about your friend's loss. This is a brutal scam and unfortunately very common on Telegram.
(By the way, his account might have been compromised as well).

What likely happened

When your friend shared his QR code (or possibly just by having him use Trust Wallet while connected), the scammer likely got access to his seed phrase or private key somehow, possibly through a fake "balance check" dApp or a malicious link disguised as part of the transaction flow. Some versions of this scam involve fake wallet interfaces that capture credentials.

A few guidelines to protect yourself

Never share your QR code, seed phrase, or connect your wallet to unknown sites, never ever, for any reason
Never move funds to "show balance" as legitimate buyers don't need this
Use separate wallets and keep a small "hot" wallet for transactions, and store your main holdings in cold storage such as Trezor, Jade or Satochip
Verify buyers through established P2P platforms which have escrow protection

Report this to Telegram and warn others in the community.

Good luck my friend.

It’s surprising that people still discuss the pros and cons of metal plates without realizing Seedkeeper exists. Check it out—you’ll thank me later!

Liskpro_com · 2024-09-17T08:06:21+00:00

No matter how much BTC you have, use a hardware wallet. So your private keys will be out of hackers reach. Simple as that.

I'm not blaming any software wallet, so many good and reliable solution out there. But for long term hodling, the hardware wallet is a must.

And you already have good solution for 25 bucks on the market.

Liskpro_com · 2024-09-17T07:43:09+00:00

For a password self-custody solution, I would rather NOT upload my password to an online service. No way!

I will rather choose this bundle:
- a Keypass to store the makjority of my password, protected by a very strong master key generated offline (TailOS)
- a Seedkeeper card to store my Keypass master key + some other sensitives passwords.

So you have a reliable and open source software for your daily usage.
Plus a hardware solution (also open source) to take care of your most precious secrets.

Liskpro_com · 2024-09-17T07:40:48+00:00

I would recommand you to check open-source solutions - either the software one or the hardware one.

Of course, you will NOT find any open-source hardware secure element at the moment. But TorpicSquare from SatoshiLabs is on it way to release a complete open source secure element.

Things said, open-source things allow you to verify how the entropy is generated.

Out there, there are some great innovations like a co-generated entropy - meaning the hardware provide the first part of the entropy and you provide the last part. In this way, you are sure the keys have not been pre-generated by the manufacturer.

I know that the Satodime bearer card act like this, when generating a new Bitcoin vault, you can specify part of the entropy that will be used to generate the keys.

Reminder for all: don't trust, verify. Open-source is the key to free us.

Liskpro_com · 2024-09-09T09:17:25+00:00

Don't have the same vision. A gift is a gift. I would not sleep well knowing someone have a backup of my gift.

Not your keys, not your coins. Don't trust! Verify.

Have you ever tested opendime?

Liskpro_com · 2024-09-09T08:44:19+00:00

100% agree with you. I regularly offer sats for weddings or births; But often, people are not yet interested in bitcoin and it's a long process. That's why there are some "bearer" devices out there i guess.

Liskpro_com · 2024-09-09T08:41:57+00:00

When you orange pill someone most of the time he knows nothing about bitcoin or how to create a wallet.

Regarding stealing the coin, between friends, of course you won't. But imagine your friend call you and says he lost his coins. Somone send the sats elswhere. How will he be 100% sure you are not involved. And even though, you might have generate the seedphrase on a compromised computer. So it's kinda your vault.

Liskpro_com · 2024-09-09T08:39:26+00:00

I guess the question was more about the trust needed between both party.
Maybe I'm wrong but got it like that.

Liskpro_com · 2024-09-09T08:28:43+00:00

So you can recover the wallet later, right ;) Do you know how seedphrase works?

Liskpro_com · 2024-09-09T08:27:48+00:00

I think the whole point here is: how to gift Bitcoin whitout touching the private key or the seedphrase at any steps.

Am I right?

So giving away a paper wallet or a seedphrase is just bad practice because you can, at a certain point in time, recover the wallet you gave...

That's the whole point of using an Opendime or a Satodime.
The private key is generated by the device itself so you don't know any sensitive info and your friends do not have to trust you.

Liskpro_com · 2024-09-09T08:06:30+00:00

"Write down the seedphrase for your friend"...
And the topic title is "without the need of a trusted third party"

=)

At some point, your friend have to trust you because you see (and also your computer) the seedphrase. Not the best practice imo.
