Olha, não olhei com detalhes, mas acho q isso aqui talvez ajude

Pois é, esse nunca nem deu uma navegada no fórum.

Aqui o pessoal usa btc como moeda no dia a dia para qualquer serviço que seja possível fazer na internet. Desde resolver catchas, fazer páginas web, assinaturas, imagens, trabalhos como desenvolvedor,....

E o mercado financeiro nao é diretamente correlacionado ao bitcoin tb...

Só acertou que o bitcoin tem crises cíclicas e volatilidade...

Bump after some months.

One merit source was added to Portuguese board, but it's not enough in my opinion.

Other boards like the Russian and Indonesian have highly merited users, but Portuguese board does not. Nobody is able to rank up just posting in the Portuguese board.

I had this crazy idea some other day.
I was thinking about this wall observer pool. Pages of this thread could be used to count  time.

What if instead of "December 15 closing price" we had something like page 24000 closing price"? Lol

Bastante interessante. Eu realmente sempre ignorei as referências do white paper do bitcoin. É inegável a semelhança com o blockchain.

Por isso q o Andreas Antonopoulos sempre fala que a grande invenção do Satoshi é o proof of work, pois foi o que permitiu que esse sistema funcionasse (e que não foi previsto nesse artigo do wei daí). Vou estudar mais sobre esse assunto.

Cada vez mais encontramos só desinformação e notícias repetidas por aí. Bom ver algo real e de qualidade.

Congratulations Lucius and oeleo.

Hard competition.

I will keep trying until accepted one day. This is the best campaign in my opinion.

I don't think it is shitposting, but it is quite irrelevant because nobody is expected to be paid in litecoin here, and there are other coins which starts with 3 (like many of the recently Bitcoin forks). Do I need to specify that this is not a bitcoin private address?

And all this drama is so off topic...

Well, that's right. I just use a different back up method. Authy.

Your method works well too.

Have you ever tried to fuking writing down this crazy GA seed ? It's not like a recovery phrase with 12 words... Looks much more like an address.

I have dozens of 2fa seeds, if I had to write all of them I would be fuked up.

Google authenticatior (ga) is not obscure about anything. They clearly state at their website that if you lose your phone, it is over. There is no backup or anything. It is safer, because it cannot be hacked... So safe that even you cannot access if you lose it.

What you can do is use Authy instead of GA, which is backed up in a cloud... It is less secure, as it can be hacked.

Those accounts are valuable.
They do not hold BTC, but they may have sentiment value... They also have can be used to earn BTC through campaigns/bounties. They also carry your reputation, as some of those accounts have holder hundreds of BTC as escrow or something like that .. some also are used by professional developers..

So, those accounts should be more protected in my opinion.

The value was not spend. I saw the address few months ago and it was intact. I don't want tk find it now but someone posted in a topic few time ago.

I doubt this new forum software is going to beê released anytime soon. I agree with you about 2fa and recovery, that's urgent.

Hilariousandco said it will be released soon (automatic recovery).

2fa is a dream which will never come true. However it would generate a lot of problems too, as people would soon be crying about losing their Google authenticatior...

Vai no REPUTATION e conta a situação.  Não vai no meta.

Na aba REPUTATION varios DT members podem te ajudar. DT Members sao outros membros com default trust
Algum deles pode te dar um trust positivo, tornando zero o seu trust atual. Ou até alguém pode convencer o Max a dar neutral.

Além disso, envie um pm bem educado para ele, pedindo pra mudar pra neutral

Recomendo ainda que não use seu e-mail que está no perfil, que realmente parece enganoso (bitcoincorebr).

Uma outra opção ainda seria nesse seu post pedir ao theymos q te de um Rename no perfil. Você poderia escolher outro nome parecido.. #BitcoinNucleo sei lá #BitcoinBR sei lá. Você pode até mandar um pm so theymos. Acho que vale tentar.

Me mande um pm quando criar o tópico la q eu dou uma comentada nesse sentido, de que você nunca tentou se passar por ngm.

Não se preocupe que eu acredito que a situação sera resolvida.

You define the gas price. Those ERC-20 tokens you are talking about probably have a high Gas Limit.

You should always use the recommended gas limit, there is no problem if you put too much Gas , because you will be refunded if you send too much gas.

 Gas Price is the atribute you can reduce, and that is what is going to control the fees of the transaction.

One more merit statistics post.

If we only had so many Bitcoin statistics posts...

Pergunta atual

O que acontece se o hashrate cair demais? Existem mecanismos no protocolo do Bitcoin para defender a rede nesse caso, a longo prazo?

Let's suppose you bought 1 BTC.

The idea to hold is that you will always have one btc. Holding, you will never lose this 1 BTC.
If you sell at a 10% "stop loss"you may fall in a bear trap, and when you try to buy again the price may be higher and you will buy only 0.75 with that money

Holding is really a good strategy in a bull market. In a bear market it is not a good strategy. However, cryptocurrencies have a long term upward moviment, so holding was the best strategy so far.

You are not a good holder :p

Ok, First of all I will tell you that this is a bitcoin forum, and this post should be in Altcoin discussion session.

For your questions, first of all you need to understand that ethereum is a "world computer", where everything is proceessed by the whole network. So, if it was possible to make a zero gas transaction, that would easily result in a dos attack (denial of service).

 For example, someone would create a script of infinity transactions in a loop, until the network goes down.
What prevents a DOS attack in ethereum Network is that everything costs gas. So you have to pay for everything you do in the network.

So, the whole gas system was created in such a way to prevent this from happening. As gavin wood said, in a world computer, waste of computer resources would mean waste of world resources.

Regarding your example, you can see that the user spent 37263 gas. However, the gas prices was set to zero. I believe there are two possible explainations for that:
1- the gas price is not zero (0.000000), but something so low that etherscan consider as zero, such as 0.00000001 eth .
2- the owner of the transaction is a miner, and he decided to include this transaction in a block anyway. . I am not sure if that is possible in ethereum network, but it MAY be.

I made this post explaining ethereum gas system some time ago:
https://bitcointalk.org/index.php?topic=3285767.msg34270190#msg34270190

You cannot control how much gas is necessary to make a transaction. If you set a low gas for a transaction, it won't be processed. What you can set is the gas PRICE, which is , in this case, low. I don't believe it is zero, but so low that etherscan cannot see it.

As you can see, he paid a lot of gas for this transaction. Who decides how much is the minimum acceptable gas price is the miner.

Maybe that's the case of putting a neutral/negative trust until he proves he is the owner of the address? Because it really looks like a hacked/bought account, and his trust is from 2016/2013, prior to hack/bought.
