Sempre que puder eu ajudo reconhecendo posts bons, estou ajudando o @criptoevangelista e o @pumared no momento a subirem de ranking (se tiver mais alguém full ou Sr. me deixe saber) Desde o meu retorno, quando não passo tempo escrevendo aqui eu passo tempo estudando sobre como trazer artigos bons e técnicos aqui.

Se contar os mais ativos aqui, acho que dá uns 10 - 13 que estão todo dia aqui no fórum, esse número precisa aumentar pra circulação de merits ficar (ainda) mais interessante, eu estou convidando algumas pessoas do meio cripto a conhecer o fórum, algumas até se registraram e está começando agora, terão todo o meu apoio, mas para não mostrar favoritivismo, deverão mostrar serviço rsrsrs então os merits são incentivos (até rimou).

@criptoevangelista você está quase alcançando o mínimo de mérits pra hero, isso significa que quando você tiver activity o suficiente pra virar Sr. você não precisará se preocupar em ter que ralar pra virar hero.

E pessoal, fiquem tranquilos, eu não vou mais sumir (pra dizer a verdade, eu visitava o fórum de vez em quando, mas não fazia posts).

Bem que o pessoal das antigas podiam voltar, hum.

It's not advisable to split a seedphrase into two parts or more, if you want to have a protected backup, it's safer and more reliable to extend these words (passphrase) where the seedphrase is something you have and the passphrase is something you know.

Não concordo com tudo que ele diz, ele afirma que Bitcoin é uma boa reserva de valor, mas está longe, muito longe de ser uma moeda e unidade de conta. Nisso eu concordo, mas ele se esqueceu de citar que para uma moeda ser aceita universalmente sem o apoio do governo (curso forçado), leva-se tempo, como o Bitcoin é voluntário, ele está passando por uma fase de transição e conforme as pessoas vêem uso nele, vão adotá-lo pouco a pouco.

Nesse momento, a maioria das pessoas estão interessadas em ver o Bitcoin como reserva de valor e ativo de proteção contra inflação ou mesmo como um ativo de investimento, mas nesse ciclo, devido a fatores como a Blackrock, aprovação dos ETFs e a valorização vem chamando muito à atenção do público em geral. Achei que isso ia demorar mais pra acontecer, mas já está acontecendo, estamos talvez na metade do caminho da fase de transição, quando arrumarem um jeito de resolver a escabilidade do Bitcoin onchain e redes de 2º camada como a Lightning se tornar mais fácil de usar, mais e mais pessoas verão usos nele.

Yes, you're right. Although I knew this detail, I didn't make it very clear. I think extended words is the best definition.

The most adopted and convenient method of making backups of an HD wallet is by writing down a sequence of words known as the BIP39 recovery phrase (or simply seedphrase) which when combined form a seed that derives the masterprivkey and, consequently, the child keys and Adresses.

It is up to you to write down this seedphrase and store it safely in an offline environment, such as on paper, steel plates, etc. Never store it online i.e. in an online notepad or email, because if your computer is compromised, it becomes very easy for someone to steal your bitcoins.

However, if you store it in a physical location such as your office drawer, and someone has possession of this seedphrase and has sufficient knowledge of the importance of this information, they could act maliciously and steal your money. A commonly used solution to avoid this problem would be to encrypt the seedphrase and there are several methods and some of them vary in security i.e some users encrypt a seedphrase with aes, gpg, compression tools like winrar, 7zip protected by passwords (I've done this a lot in the past) and also with BIP39 Passphrase.

Of these methods mentioned, BIP39 Passphrase is undoubtedly the most used due to it being widely used by hardware wallets, as in addition to being the most secure, it reinforces the entropy of your seedphrase by combining your seedphrase + passphrase generated by you, resulting in a wallet unique access code "hidden" behind that password.

Regardless of the method chosen, the user now has to save 2 information: Seedphrase + password, and in the case of BIP39 Passphrase, the passphrase must always be memorable, as there is no way to recover it if it's lost and it'd only be used if you fully understand how it works.

Some wallets such as Electrum, Sparrow, Bitcoin Core and Schildbach wallet have a functionality to import/export encrypted backups with your wallet's encryption password, and this is very interesting, as in addition to being done in a theoretically safe way, you don't need to resort to other third-party encryption methods that may compromise your seedphrase. With this encrypted digital backup, you can easily make multiple copies and spread them to different locations such as pen drives, SD cards and the cloud.



If you want to make encrypted digital backups, Electrum and Sparrow are one of the wallets that allow you to do this safely, but I leave some observations below:

• There are more than one type of seed: BIP39 and Electrum, BIP39 is accepted in most wallets, while Electrum seeds are only adopted by Electrum.
• If you want to do this on Electrum, your wallet needs to be created on Electrum, as a native Electrum wallet allows Electrum to save your encrypted seedphrase and whenever you need that seedphrase, you can view the backup and make physical copies by writing it down on paper, and a BIP39 wallet that was imported into electrum is not possible, because in this case Electrum don't save the imported seedphrase, it only uses it at the time of import to calculate xpriv/ypriv/zpriv, but if you want, even so if you saving a digital copy of a BIP39 wallet imported into Electrum, you can recover the funds, but your seedphrase won't be saved in the file (unless it's a native electrum wallet).
• If you want to make a digital backup of a BIP39 seedphrase, you can use Sparrow Wallet for this, you can either create a new wallet with or without a passphrase or import an existing seedphrase, encrypt the wallet with a good password. If you need to import your seed to another wallet, you can open the backup generated by sparrow (using Sparrow Software) using your password and view the seedphrase to import into another wallet.

With the tips above, you don't need to risk your security by experimenting with encryption methods that could compromise your wallet. Of course, even if you follow the tips above, but do it on an insecure computer, compromised with internet access, you may still have chances of having your wallet compromised. So the ideal is to do this from an airgapped computer without internet access, preferably a computer just for this that you won't use for anything else.

Trezor Suite has the best UI in my opinion, but when it comes to UX, Electrum and Bitcoin Core are more objective. It has the Send, Receive button, I just think that both Electrum and Bitcoin core should return to having dynamic QR Codes, when changing the amount or description the QR is instantly updated instead of clicking on "create new receiving address" and a new QR Code.

About Electrum's retro UI, this pleases me, because remembering graphical interfaces from the XP era is very nostalgic, electrum reminds me of those password managers like Keepass.

Well, Sparrow has an integrated block explorer, do you already know it?

the 12 word length standard is the accepted standard in 95% of wallets, what guarantee do u have that a seed of just 3 words will be accepted by other wallets? Understand that this causes the versatility of the backup to be lost, being limited to a few wallets that accept restoring a 3-word seed + passphrase.

Your passphrase must be long enough to compensate for the weak security of a 3-word seed, which creates another problem, how will you guarantee that you'll remember this passphrase when you need to restore funds? It's easier for you to follow the standard of at least 12 words and use a good passphrase using words + numbers and some symbols, thus striking a good balance between increasing security and avoiding forgetfulness.

I see that the only justification for choosing a seed of 3 words instead of 12 is to make it easier to remember, but there are safer ways to do this...

It's easy to memorize a seed of 12 words and some passphrases, but never rely solely on your brain due to the risk of amnesia, spread your backup geographically without giving obvious clues that it has anything to do with bitcoin.

Thank you for participating in this campaign and for the opportunity @suzanne5223 it'll be a pleasure to work with you on future projects.

I'd take 1 BTC immediately and then think about what I do with it, I'd divide this prize between 20% for variable income investments and only 2% in betting and sports betting and the rest I would keep in hodl.

Mas existe um grande problema nessa questão aí, você vai depender se o seu governo não for corrupto como o governo brasileiro, se o governo/gestão do seu governo for o mínimo corrupto possível, eu entendo o seu ponto. Agora se o governo do seu país for composto onde a maioria é corrupto e não estão nem aí pra população, então temos um problema. Pois a maioria do dinheiro pago em impostos não serão gastos com o que foi prometido e você está ferrado.

I'm sorry for your loss OP, but take this as a learning experience and based on it, as well as serving as an experience for us because you're telling us something that's useful for you.

Some people actually work more than they spend time in leisure, this is sad for bettors. When you are feeling tired or stressed, try to satisfy your adrenaline levels in other activities that do not depend on your bets at that moment, such as playing a video game, or even researching the team you are betting on and seeing their current conditions to place a bet when you are cool-headed and refreshed.

Update: Já foi preenchida

As Stalker22 suggested, the closest solution to what you are looking for is BIP85.

To summarize, BIP85 makes it possible to derive from the original seed infinite seeds, WIF or XPRIV through indexing from 0 to what is allowed by this BIP similar to what an HD wallet does to derive the private key addresses via index i.e: m/0/0/0 address1, m/0/0/1 address2 and so on. But in BIP85 it's directly from a number that goes from 0 to unknown, for example 999999.

When choosing an index number, it'll always generate the same seed, WIF or XPRIV, if the seed is protected by the BIP39 passphrase it'll generate completely different seeds and the rest.

In BIP85, the seeds generated are unique and the child seed cannot reach the mother seed, so there is no problem if an attacker discovers your child seeds if your funds are in the mother seed (this is just an example), because with the child seeds they'll not be able to calculate up to the mother seed.

You can use this for plausible deniability, for example, generating a BIP39 seed, protecting it with Passphrase BIP39 and generating a new seed using this seed in BIP85, with this you can safely store your original seed, because even if an attacker physically accesses your original seed, he still needs to know the BIP39 Passphrase and in addition, he still needs to know which index you used to access the seed that contains your funds, and you can still protect this child seed with BIP39 Passphrase making it even more difficult for any attacker.

Realize that your security increases, but with great power comes great responsibilities, the risk also increases a lot:

• There is a high chance that you will make a mistake in the middle of the setup.
• Will you remember how to recover the funds if many years pass?

I think that an extended seed (seed + passphrase) would already meet your demand, because a wallet protected with BIP39 passphrase, even if the attacker physically accesses your seed, unless he doesn't know your BIP39 Passphrase, it will be useless for him to try anything.

Furthermore, as some mentioned, passphrases make it possible to create infinite wallets using a single seed.
Be careful, do your research before making any decision, because in bitcoin, one slip-up can cost you all your funds.

Eu não sei te informar sobre isso, vou procurar saber mais tarde. Se tiver atualização disponível, vou procurar sim.

Meu sonho sempre foi ter um MacBook e eu ainda não vou desistir de ter um, acho eles ótimos pra tudo que se propões a fazer, ainda mais se você tiver iPhone/iPad.

Deixa eu ver se eu entendi? Está proibido na europa fazer pagamentos de carteiras cripto de auto-custódia? Que absurdo, só prova que o governo tem muito a temer com a revolução Web3, está vendo seu aparato está se tornando obsoleto. Mas a longo prazo será um tiro no pé, pois nenhuma proibição de bitcoin funcionou (na verdade, causa o efeito contrário).

Eu tava assistindo vídeo sobre o assunto do canal Ancap.su do Youtube. Rapaz, em alguns casos, a europa está pior que o brasil, em vez de reduzir os impostos, não interferir no mercado eles tomam atitudes que beira ao infantil de criança que para uma partida de futebol bruscamente pra levar a bola pra casa porque não gostou de alguma coisa que o coleguinha fez ou falou dele.

Por isso que a cada dia o descontentamento das pessoas frente aos governos crescem e com isso migram pro bitcoin e cripto em geral, a cada dia que passa, as pessoas percebem que os governos de todo o mundo só atrapalham e limitam o cidadão de alcançar objetivos pessoais, além de não cumprir com o básico que prometem: saúde, segurança, saneamento básico e infraestrutura em geral.

Essa bancada política mal sabem o funcionamento de tecnologias ponto-a-ponto como o bitcoin que são imparáveis devido a sua natureza descentralizada, porque a maioria são um bando de velhos burros que mal sabem o básico de informática.
