You never saw a 1 sat/byte get dropped =/= no 1 sat/byte have ever been dropped. I have seen plenty and limiting facts to what you saw is wrong. Wasn’t you here when the mempool hit its ATH and you literally had 1-3 sat/byte stuck for days? You can’t deny that... it happened. It’s a fact. You are the one denying it, saying that 1 sat byte get dropped and not stuck. I saw that, it was a fact: they didn't drop, they were waiting for confirmation for some hours/days, in the All Time High Congestion. Just like I said before. Yes... that’s the situation NOW. This in no way means 1 sat/byte transactions are drop-safe. What happens if suddenly someone starts spamming the mempool like they did some years ago? Or if China starts encouraging BTC usage and a big part of the population follows them? Possibilities.
...
I can literally spend million in 100+ sat/byte tx for weeks. Isn’t that possible and totally viable if I have the money to burn? How can you deny that and affirm 100 sat/byte tx will stop showing up? You don’t know that. And I personally had 1 sat/byte txs get stuck for days.
TryNinja, I get your point. Ok, You want to justify that we shouldn't use 1 sat byte fees, but we should use higher fees. I don't agree, but that's ok. Your "possibilities" like a suddently BTC adoption that will make BTC become highly used by common people in a few hours, or that someone very rich like Jeff Besos is going to spam the network with 100sat/byte for months didn't convince me. Those "peaks" of congestion are much more like an attack (when BCH was listed in coinbase for example and BCH were spamming the network) or very uncommon situations, and they don't last for more than like 2 days. I will continue using 1 sat /byte fees as I always did, since 2017, and I am ok with that. I know someday one transaction my be dropped, although it is very unlikely and I have never seen it, and I have done at least 30 1sat/fee txs. (and if it get dropped, I will sent it again with 1 sat byte fee until accepted!)
This is certainly a very interesting case. So there are payment processors using 0 confirmation transactions. I think that for small values there is certainly very few people who are willing to scam using this RBF process. And it is possible to calculate a fee to compensate scammers: If 1% of all people do a successful double spend (RBF whatever the name) than you just charge 1% on fees. Burguer king is doing that somehow, but using 4% fees according to the journalist. Translation: "Commission fee is a little more than 4% for all currencies with no exception..." |

This DID happen a lot since it’s how Bitcoin was made to work. If you have tons of 100 sat/byte+ tx, why would a miner pick your 1 sat/byte? If 100+ keep comming, they will keep getting priorized, never making room for your tx. Then, nodes will start to drop it.
However those 100 sat/byte tx will stop coming sooner or later, making room for 1 sat/byte tx. From my experience, sooner than later. I never saw a dropped Tx, I will take a look if I can find one. I keep making 1 sat fee tx and they keep getting confirmed within a few hours. As I said, I made one last week during our price spikes. No issues ,8 hours to get 1 confirmation. I think more people should do 1 sat/byte tx. Most of those 100 sat/byte are probably done by exchanges and shitful wallets which don't let users control fees, artificially inflating fees to benefit miners... literally abusing newbies lack of knowledge. But that's another discussion.. |

Então bit, dei uma olhada nos sites oficiais da Ledger e da Trezor e os preços estão bem convidativos, muito mais em conta comparados com o Brasil, achei interessante.
Quando você comprou a sua carteira, você comprou no site oficial mesmo? Desculpa pela curiosidade, foi uma Ledger ou Trezor? Valeu a pena? Demorou + ou - quanto tempo pra chegar? Você chegou a ser taxado pela Receita Federal?
Obrigado!
No meu caso eu comprei com um amigo que foi para a França e trouxe.. Eu uso uma ledger nano s e estou 100% satisfeito e recomendo. A trezor acredito ser igualmente boa. Eu já acompanhei pessoas que compraram no site da ledger, oficial. Demora uns 30 dias pra chegar (talvez menos, uns 20). Mas você provavelmente será taxado em torno de 40% (uns 100 -150 reais). Mesmo c k imposto o preço ainda é mais em conta. Adicionalmente você terá mais segurança, pois sabemos que no Brasil esse setor de criptomoedas é dominado por golpistas. Eu não pensaria duas vezes: compre na ledger.com e pague o imposto.(talvez nem cobrem se v der sorte, mas já prepare-se) |

Quais foram as criptomoedas que antecederam o Bitcoin?
Houveram algumas tentativas mas elas fracassaram, principalmente pq elas tinha um ponto central de fraqueza, ou seja, não eram descentralizadas.

Tenho jogado alguns deles na blockchain steem:
Splinterlands - Card game que oferece recompensas diárias em forma de cards e de uma moeda interna chamada DEC (que pode ser vendida por steem ou usada para comprar cards e outros itens). Também é possível acumular DEC vendendo cards e participando de torneios.
EU joguei um pouco desse jogo pra ver como é. Ele não roda no blockchain como o cryltokities (que precisa até de saldo pra jogar) Ele somente permite que você compre coisas no jogo com criptomoedas, e ele até tem uma moeda própria. Nada demais... joguinho interessante. É bom por um lado não precisar de saldo pra jogar e ganhar uma token jogando. Da pra ganhar alguns trocados jogando |

I think that for example the number of posts should have taken a more important spot itself, since the advertiser will want to see its banner on many places - new and old.
I don't deny that there are many valuable applications, but going only by merits (and maybe started topics) you seem to be missing something important.
I liked this topic because he is showing where the users earned their merits. Some of those users got 99% of their merits in some local board. Others got on 2-3 different boards. I think his stats are useful for dark star to find who posts where he wants. |

I had not tried it but I believe some non-custodial wallet allow for double spent.
That is the thing. Nobody ever tried and I saw just speculations here. I took a look on the web, I couldn't find any wallet which allow you to double spend. I found a guide on electrum which allowed users to double spend : but you need to recover your private key in a new wallet. Lots of work, a big guide. Take a look. He is teaching how to make a RFB transaction (replace by fee) https://steemit.com/bitcoin/@profitgenerator/tutorial-how-to-fix-unconfirmed-transactionsTheir problem is the fee and purchase amount, did they have a minimum?
For the minimum allowed amount, if they are taking too much 1$ transactions, they will lose more bitcoins as a transaction fee for consolidating those satoshi.
It's better if they only accept Bitcoin for $5 and above transactions.
For the fee, there was a time that a 1sat/byte can take days to confirm or even drop after 2weeks,
that's a Dec 2017 thing, but still applicable today though.
$1 is a lot. You can consolidate your inputs which have more than 0.30 for example. If you use 1sat/byte fee your transaction will be very cheap, and it will get confirmed in a few hours . I never a saw transactions being dropped, I believe this is much older than 2017 (probably a zero fee transaction, which is not accepted anymore) Since 2017 I am using 1sat/byte fee and I never saw more than 30hours to have a transaction confirmed. I made one transaction last week which took 8h to be confirmed. For burguer king in this case it is very good for them because they are in Venezuela. Their fiat is more volatile than bitcoin, so it is a win-win game for them. |

Wow, that's a heck of a lot of work you did there!
I Agree. This is one of the most interesting statics I have ever seen here. I don't even remember what I got merits for in Off-Topic. It must mostly be for combatting notbatman in the Flat Earth thread.
I think Off-topic and deleted posts were merged? Probably you got some merits from deleted posts. But each bitcointalk member has a different scope of posts and may not necessarily cover all, maybe only a few can cover it all.
lol nobody can cover it all. This is why it is not a one-man campaign. The idea is to work as a team.
Great job tranthidung. This will probably help out Darkstar_. We can see now clearly where are users are spendning their time in the forum, and where they are making relevant contributions. Congrats. |

Is it related to Bitcoin (payment in Bitcoin)? If it is then I think it should be in Service Discussion. If it doesn't then don't post it in Bitcointalk. No, that is incorrect There is an altcoin session in bitcointalk You can post it in Service Discussion (Altcoins) if it is altcoin related. Actually, bitcointalk is one of the best resources of information for altcoins. There are ANN of basically every shitcoin in this forum, where you can contact someone from their team direct and updated information about all those altcoin related projects. |

A Trezor One esta R$ 419,00 com pagamento em criptomoeda, já como eu estou pretendendo comprar no cartão, existe essa opção, ai quando eu clico, me redireciona pro site da AmazonBR, mas infelizmente o valor pra quem quer comprar no cartão altera, passando para R$ 699,00.  Bom, esses são um dos principais motivos de eu querer comprar a hardware wallet no exterior Cara nem perca tempo fazendo cotação no Brasil. No site oficial está sendo vendida por 229 a ledger nano s. Você tá falando aí no dobro e no triplo dos valores. O cara compra no site oficial, paga imposto e ainda quer tirar 100% Que país difícil esse nosso hein. |

I have 6 strings of characters need to combine in some way to form the passphrase. Might have only used 4 or 5 of them though, can't remember.
Can you be more specific, so we can help you out? Do you have a set of 6 words, which you don't know the order? If that's the case, it is a lot easier: 6×5×4×3×2=720 only. Easy to brute force. You are being very generic so it is hard to understand your problem. |

Eu comprei.
Você deve comprar somente no site do fabricante, eu não compraria na Amazon não.
Compre em ledger.com, não compre em nenhum revendedor , por questões de segurança.
Existem alguns bugs tanto na trezor quanto na ledger que podem comprometer suas moedas se um hacker fizer uma alteração no firmware do dispositivo (pra isso ele precisa de acesso físico a sua carteira)
Então nem arrisque em revendedores.
Compre na ledger.com
Vem direto da fábrica, sem erro.
Vc vai provavelmente pagar 40% de imposto e mesmo assim é mais barato do que comprar no Brasil.
Não se preocupe quanto a garantia e suporte, nunca vi ninguém que comprou um aparelho que veio defeituoso.

If you sent bitcoin with a near-zero fee, there's a chance it could get sent back to the originating wallet if I'm not mistaken. That happened to me at least once a couple of years ago when the network was extremely congested.
This doesn't happen any more. I always use 1sat/byte fee (the minimum fee allowed) and I never saw any transaction go back. It will just take long confirmation times (never saw it takes more than 20hours even when extremely congested. |

Are you sure what are all the words and you just forgot the order? I don't think there is much you can do. It is not easy to brute force it. There are trillions of possibilities 24x23x22x21x20.... If that was so easy to recover a private key , nobody's coins would be safe. I saw this post by Danny Hamilton from few years go (made google searche about your problem) So, you have 24 words.
That means that you have 24 possibilities for the word in position number 1.
If you try each of those words in position number 1, that leaves 23 words to try in position number 2.
Try the first word, with each of the other 23 in the second position, then try the second word with each of the other 23 in the second position, then the third word with each of the other 23 in the second position and so on.
When you've done that, you'll have tried:24 X 23 = 552 different possibilities.
Each of those 552 possibilities will have 22 remaining words that you can try in the third position.
So that's:
552 X 22 = 12144 possible combinations of 3 out of the 24 words.
(Notice that's the same as 24 X 23 X 22 = 12144)
Then for each of those 12144 possibilities will have 21 remaining words that you can try in the third position
That's:
12144 X 21 = 255024 possible combinations of 4 out of the 24 words.
(Notice that's the same as 24 X 23 X 22 X 21= 255024)
Perhaps you can see now that as we continue, by the time you try all the 24 word combinations of 24 words, the pattern will repeat all the way to:
24 X 23 X 22 X 21 X 20 X 19 X 18 X 17 X 16 X 15 X 14 X 13 X 12 X 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1 = ?
In maths that pattern is called a "factorial" and is represented as:
24!
If you do that multiplication, you'll find that the total number of combinations you'll have to try will be:
620448401733239439360000
That's about 6.2 X 1023.
Lets assume that you have enough computing power to try 100 trillion combinations per second.
620448401733239439360000 combinations / 100000000000000 combinatins per second = 6204484017 seconds.
Since there are 60 seconds in a minute, that is:
6204484017 seconds / 60 seconds per minute = 103408066 minutes.
There are 60 minutes in an hour, so:
103408066 minutes / 60 minutes per hour = 1723467 hours.
There are 24 hours in a day...
1723467 hours / 24 hours per day = 71811 days.
There are about 365.25 days per year...
71811 days / 365.25 days per year = 196.6 years.
If you actually had the ability to try 100 trillion combinations per second, then it's going to take you nearly 200 years of trying non-stop 24 hours a day to try all the combinations.
If the number of attempts you can make per second is less, then obviously it's going to take you longer than that.
The only way you are going to be able to find the right combination in your lifetime is if you already have some of the words in the right order, or if you can remember what order some of the words belong in. Knowing for certain the position of just 1 word reduces the effort required by a factor of 24. Knowing for certain the position of just 2 words reduces the effort by a factor of 552.
Using our "100 trillion combinations per second" example, knowing for certain the position of 1 word reduces the time required to try all possibilities from 196.6 years to:
196.6 / 24 = 8.2 years.
Knowing for certain the position of 2 words reduces the time required to try all possibilities to:
196.6 / 552 = 0.36 years (about 4.3 months)

I don't know I you guys saw this news: https://decrypt.co/16998/confirmed-craig-wright-doesnt-have-keys-to-8-billion-of-bitcoinCraig Wright’s lawyer confirmed to Decrypt today that Wright does not possess—nor even claim to possess—the private keys that can be used to spend $8 billion of Bitcoin that Satoshi Nakamoto mined in Bitcoin’s early days. That troll is just trying to fool newbies, who doesn't understand how things work: what is a private key, a bitcoin address and so on. He doesn't even claim to have the keys: because he never had. However, he is certainly making a lot of money in thise BSV's pumps.... |

I saw this article recently, where the journalist shares his experience paying for a hamburger in burguer king and paying with bitcoin. I found very interesting to see burguer king is accepting zero confirmation transactions. https://es.cointelegraph.com/news/i-used-bitcoin-to-pay-for-a-burger-at-burger-kingAdemás, en mi caso, redujo la posible fricción temporal de cara al comercio, pues el tiempo de confirmaciones de la transacción en la blockchain de Bitcoin se redujo a 0, ya que Cryptobuyer asume el pago sin confirmaciones. I believe most of the people in the world are honest enough to not even try to double spend ( I may be naive, but i prefer to live like this than to consider everyone is a thief) Anyway, I was thinking how easy is it to do a double le spending in this case? Have anyone ever tried? The transaction broadcast is almost instantaneous across all the network. Does broadcast time makes any difference? I believe most wallets won't let you double spend (never tried..) My question is: If you have a transaction which is already broadcasted across all full nodes mempool, if you send a other one with a higher fee, will nodes recognize it as a legit transaction? If it is possible, isn't it a good idea to create a BIP proposing to disallow to double spend of a transaction already in mempool? What would be the cons against that? Newbie question but I always thought zero confirmation transactions are interesting. |

Transações instantâneas
As transações de compra e venda são realizadas rapidamente. E, num mundo onde tempo é dinheiro, é um ponto super importante para quem não quer perder tempo para começar a ganhar dinheiro.
Em geral, uma transação realizada entre uma carteira e outra leva em torno de 10 minutos.
De certa forma, instantaneamente você vê que a transação foi feita. Contudo, a primeira confirmação vai demorar 10 minutos Se a taxa for suficientemente alta para ser inserida no próximos bloco E não vale a pena pagar essa taxa, q em geral é muito alta. Mas se vc inserir uma taxa razoável, em menos de 1h a transação estará confirmada. Mas já existem estabelecimentosestabelecimento aceitando transações sem nenhum confirmação. Eu acho q isso faz sentido para pequenos valores, pq poucas pessoas vao agir de forma desonesta tentando realizar um gasto duplo pra roubar alguns reais. Eu acredito na honestidade das pessoas rsrs Vou pesquisar mais sobre como esse gasto duplo pode ser feito e se realmente é fácil fazer... pq a transação se propaga muito rapidamente na rede. |

Cara sinceramente o pessoal tenta correlacionar os movimentos de preço do Bitcoin com qualquer tipo de evento aleatório.
Não acredito que a ocorrência do ano novo chinês tem essa influência toda no preço.
Bitcoin tem alta volatilidade mesmo. Nunca consegui encontrar uma lógica muito forte em correlações com esses tipos de eventos.
Do nada o preço da uns pumps ou dumps e o pessoal vemcom as teorias mais mirabolantes.

I always try to work with honesty and I want to contribute to this forum in proper way. If I do any mistake I hope you guys always aware like that and I can also promise in next I am too careful to avoid any mistake.
If you want to work with honesty why do you act so dishonestly? You promote ponzi, trying to steal other people's money. You pay for fake reviews, trying to fooling legit users.... You are far from working with honesty |

And just like that, Phemex has earned everyone's attention.
Good job to the team for having this creative way of promoting their brand.
2.1 #BTC are hidden in this picture, can you solve it? 🏆
If you can’t, RT tagging the smartest person you know: everyone in the RT chain that led the winner to the puzzle will receive a $100 trading bonus 💸
They were smart, but pay attention: They are giving a trading bonus, not 100 in btc for you to recover to your wallet. Probably you cannot even withdrawal that money from their exchange:/ |
