The history of yet another guy trying to earn money.
I wonder how much people actually think Bitcoin as money and not investment.

E essa parada de ter que esperar pra fazer outro post? Quando esse inferno acaba? Nao tenho paciencia pra isso nao rsrs


Isso é uma restrição por rank, baseado na atividade.
Os mais altos ranks esperam nem 10 segundos entre um post e outro.

A maioria das alts(as moedas alternativas ao Bitcoin) não são negociáveis nas exchanges aqui do Brasil.
Agora, dogecoin eu lembro que vi que dá pra negociar em algum lugar, só não lembro qual...

Os bancos também estão de muito olho só na "blockchain technology", e eu duvido que nos próximos 100 anos os bancos deixem de existir.

Faz um leilão, é a melhor maneira de saber o quanto tá valendo o seu miner.
E, como vai ser um leilão e o povo vai pagar mais barato por isso, sem dúvida teria gente interessada.

Único problema é receber, tem uma trambicagem pesada pra receber dinheiro de fora do Brasil...

He forgot to say how this is going to happen.
Most ways to spend Bitcoin aren't very clear, as this is the case for Dell and many others, where you need to contact them, and it only works in USA.
67  Bitcoin / Bitcoin Discussion / Re: Refuting the 5 arguments of 1mb supporters on: January 22, 2016, 10:42:47 AM
This guy has no idea what he's talking about if Google translate properly translated that page for me. There are no technical arguments and it is clearly stated on the Core roadmap for scaling why 2 MB blocks are bad right now. He talks under the assumption that Core plans on sticking with 1 MB forever and making the main chain a settlement layer for the banks. He also assumes that the fees will rise to a few hundred dollars. Both points are complete nonsense:
A) Why would banks be using Bitcoin as a settlement layer if adoption is limited? They can easily create their own.
B) Why would anyone use a system with drastically high fees when they can switch to alternatives?

The post also mentions Moore's law which is pretty much dying. Bitcoin will not stay at 1 MB.

Bitcoin will not stay at 1 MB. But it needs to move to 2MB or higher quickly to accommodate more adoption/usage.

The average user won't will start using Bitcoin just because you said "hey, come on, I made some space just for you!".
If they didn't come yet, it's not increasing by only 1MB that will convince people to use. The mass adoption won't happen so soon.

Sure, let's open it to discussion: What do people think of making this campaign a fixed rate/monthly type campaign with competitive rates (of course)?

I don't like it TBH
I feel very comfortable posting in my free time, I mean, sometimes I may post a lot in a week, other times I'll post only a few, and even if I post a lot, almost half of my posts doesn't count, since I post a lot in my local language section and sometimes in the off-topic section.
I don't like being forced to post, I want to post only when I feel that I need to.

Olha só, não é que finalmente Bitcoin chamou a atenção dos economistas?
(E não só aqueles amadores que iam falar na Forbes que o risco é grande, sendo que BTC é bem mais do que só especulação...)
70  Economy / Services / Re: [BIT-X.com] Earn Bitcoins by Posting | Signature Campaign on: January 20, 2016, 10:35:00 AM
And I noticed the bot increasing my excluded post. I have a total of  8 excluded post now including this. I reviewed all my post in this period and I think it's only around 4 or 5. Not a big deal after all but Im just curious why the bot behaves like that.

Anyways today is my payment day and hoping it's not delay again.

Thanks !!

Seens they fixed it

Edit: Nvm, this post itself is counting to the payout

Those Steam Keys are generated by Steam itself.
Only a retail seller(like g2a, humble bundle) will have a way to generate those keys, we can only have gifts in our inventory accounts.
So am I need to be a confirmed seller for Steam to buy and sell these keys? How can I be one of them? Is there any partnership page on steam?
Excellent question. I have no idea how to say that you want to be a retailer. Maybe try their contact e-mail?

73  Bitcoin / Bitcoin Discussion / Re: UK Government Urged to use Blockchain by Chief Science advisor on: January 19, 2016, 01:15:41 PM
It's not about adopting, but studying how to use anything from the structure of the blockchain.
Also note that they don't ever mention "hey let's use Bitcoin", they want control and not a open ledger.

then i don't see the point for them to even work on a centralized blockchain, what real advantages can a centralized bring, that a cluster server can not? besides being more organized and transparent

i'm not buying the whole bullshit about cost and time, their cost are minimum right now with a cluster server instead of running node for another blockchain, it would be the same

I think that like the reason the very first net was born, is the reason for using the blockchain: descentralization, have the same information on multiples servers all over the place. Server down? No worries, connect to this server and everything is OK. When that server come up running again, it will recover all the data his is behin of the network and everything will run OK.

We united against his bullshit XT.
I think he did a great job showing that no one can change Bitcoin will stupid ideas.
Thank you Mike.

You are free to start your own altcoin based on Bitcoin's blockchain, blacklisting the coins you wish to blacklist.

And in fact many people have tried it and still are trying.


Could you link to such attempts? It would be interesting to see Smiley

Folks attempting to do this can't complain about having less users than Bitcoin.

A quick search looking for "bytecoin" will show you the first attempt.
It was simply bitcoin, but with a totally new genesis block, and so, a new blockchain.

Acabei escrevendo meio na correria e não me expressei bem. Na verdade a preocupação dele era essa mesma (com relação ao servidor que controla o jogo) e a ideia era um poker distribuido, sem uma "entidade central" que pudesse trapacear, se não me engano o maior problema era com relação à fluidez do jogo quando uma das partes fosse disconectada, já que esse client teria uma das chaves que foi utilizada para embaralhar o deck.

Voce tem algum link sobre esses protocolos disponíveis ( ou pelo menos algum nome que me permita buscar no google)? Me interesso pelo assunto.

Abraço,
Adriano

esse de loteria, em especial, eu vi aqui: https://en.bitcoin.it/wiki/Contract#Example_8:_Multi-party_decentralised_lotteries (tem um link pro paper onde ele descreve o protocolo)

E o nome desse tip ode jogo/protocolo é "Mental Poker". Achei na wikiepdia :-D https://en.wikipedia.org/wiki/Mental_poker

E achei esses artigos aqui sobre o assunto :

https://bitcointalk.org/index.php?topic=362901.0
https://www.reddit.com/r/Bitcoin/comments/3mjosp/cypherpoker_mental_poker_alpha/
http://people.csail.mit.edu/ranjit/papers/poker.pdf

Não li nenhum deles a fundo pra ver como funcionam e até que ponto usam a blockchain. Mas parecem interessantes.

São propostas bem interessantes mesmo, só que são um desafio pra implementar.
78  Bitcoin / Bitcoin Discussion / Re: Bitcoin Confirmation Speed on: December 18, 2015, 01:51:30 PM
I understand and agree with most of what is being said on here about this topic, but these answers bring this conversation back around to the fact that if these purchases are not confirmed there is a chance that someone could possibly double spend before confirmation.  I know this risk is low, but that risk is why a number of vendors will not accept Bitcoin as payment currency.

Double spend a transaction is not that easy.
Even more if you pay with a smartphone in the front of the guy that is selling you the candy bar.

Of course, you're going to buy a house or a car, the seller will probably request to wait 1~6 confirmations since its risky and the value is high.
79  Bitcoin / Bitcoin Discussion / Re: Bitcoin Confirmation Speed on: December 18, 2015, 12:45:26 PM
Understand that when someone realys the transaction that more than enough to know that the seller will receive the money.
The conformations are just the way to register the transaction so the seller can use the money.

Vcs ainda acham que o MB nao eh confiavel? Estou utilizando ele por 2 anos e nunca tive nenhum problema. Ja pensei em mudar para outra exchange, mas da ultima vez que fiz isso foi pro MtGox, o resto vcs ja devem imaginar hahahahah  Cry Cry

Pensei no OkCoin mas ta ultimamente anda tao com cara de MtGox que estou receoso.

Mas, até onde conheço, no fim das contas teriamos que voltar para o MB(ou para alguma outra BR que transfira) caso queiramos recuperar o dinheiro, pois acredito que vender lá fora e fazer transferencia de dinheiro de uma exchange pra uma conta nao seja muito legal haha... Ou existe algum outro jetio que nao conheço?

O MB que está no ar hoje, se não me engano, é de outros donos e mais seguro.

Também tenho usado por meses sem qualquer problema.


Vai sonhando... Estão TODOS envolvidos até o último fio de cabelo nesse estelionato.

Não existe essa de "MB de hoje" e "MB de ontem", é tudo uma coisa só. O fato de terem criado o CNPJ do "Novo MB" logo após o golpe aplicado, na vã tentativa de se livrarem, só fortalece ainda mais o fato de que todos eles estão envolvidos.

É só dar a corda...

Os caras roubaram um monte de gente e vocês ainda vem com esse papinho de aranha... Fala sério...

Sem mais delongas,
Thiago


Cara, legal trocar ideia com alguém que tá bem por dentro do ocorrido.

Você recomenda alguma exchange brasileira? O que acha da Foxbit e b2u?

valeu!


Desculpa me intrometer.
Eles tem as exchanges deles que conseguiram uma boa clientela, não criaram nenhum esquema a la Pirate@40, então por enquanto é confiável.
Não desmerecendo a confiança que os usuários aqui no fórum já tinham quando abriram seus negócios, mas só estou fazendo um olhar mais crítico.
