Agora sobre o Merkle seed, nunca li nada a respeito, dei uma pesquisada e a única coisa que encontrei foi sobre uma compania que se chamava Merkle Seed que tem o objetivo de educar as pessoas sobre o bitcoin.
Opa, me confundi. Era Merkle Root que eu queria dizer e me confundi na hora da perguntar. Me desculpem. Merkle Root é o topo da Merkle Tree. É o ultimo Hash na estrutura que voce descreveu: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fraw.githubusercontent.com%2Fbitcoinbook%2Fbitcoinbook%2Fdevelop%2Fimages%2Fmbc2_0902.png&t=663&c=5l7kH3i3wrw6aw) A root também entra no Header do Bloco. A Merkle Root é um Hash que representa todas as Merkle Leaves (folhas), ou seja, todas as transações do bloco.

Ok, essa é pra pesquisar com calma. Pergunta - O que é uma Merkle Seed e uma Merkle Tree e como elas são usada no blockchain?

Is a blockchain just a bunch of code, what infrastructure does it need to be built? I have seen visual representations of blockchains but I haven't actually thought about what they actually look like in real life, does anyone know?
THis is the best visual explanation about the blockchain i have ever seen. I recommend that everyone watches it. https://anders.com/blockchain/Anders explains in a very visual way what is a hash, what happens when you hash a block. What happens to that hash when someone alters a transaction. What is a nonce, what is mining. This is a classic now.

I don't have a problem with KYC and his nothing to fear.
You are thinking the wrong way. This is your privacy. Even if you have nothing to hide, if you give your Identification documents, Driver's license, etc, they can be used for criminal activities.Even if the "owners" of the website do not use your documentation for illegal activities they can sell your data to third party.KYC is an issue, however it's a regulation downside.

Muito boas suas informações e concordo com tudo. Ninguém sabe quem irá ganhar nem quem serão os candidatos. Mas existe um relatório de mercado chamado FOCUS com várias previsões. Ele é feito pelo banco central e através de uma pesquisa com as 120 maiores instituições financeiras do país (bancos, corretoras, consultorias) sobre quais são suas projeções para a inflação, taxa de juros, câmbio, PIB e etc. Eles te mandam toda semana um relatório gratuito todo semana como esse: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FwFHJALP.png&t=663&c=YanlrCH7G2kTmA) Só se cadastrar nesse site e eles te mandam semanalmente http://www4.bcb.gov.br/pec/GCI/PORT/Mailing/subscrever.asp?idpai=FOCUSASSO último relatório Focus fez uma previsão de 3.43 pro fim do ano. Então estão prevendo um candidato mais a direita, q deve seguir com reformas... Vamos torcer para estarem certos. Focus é uma previsão que erra muito, mas é o de mais concreto e um dos melhores que existe no país em termos de previsão

https://bitcointalk.org/index.php?topic=4178434.0I wasn't going to post here, as this service looks focused on newbies. But I can see they are not giving it much attention... I wrote this one some other day , I really liked this post and did a lot of research. However it didn't have a good reception.

I own over 500 .com domain names, and that includes the names for all of my Internet identities, and all of my projects. They are all hosted on various hosting plans that I manage.
Hello Jet Cash, Can you talk more this? Why do you hold all these .com domain names? I never researched about hosting a .com domain. I think this could be interesting. Are you speculating, buying some unusual domains expecting them to be valuable in the future? Some other day I was reading fittotalk.com. I was impressed with the effort you put in it, and that you registered a .com domain for it.

I believe in your theory
This is not my theory but a Nobel prize winner's theory:) Bitcoin and all other cryptocurrencies have a Very strong correlation.

That makes sense, but there's something I don't get about this mathematical model... Sure, it can reduce the risk of your portfolio, but isn't it also true that it could just as well lose value and actually increase the risk of your portfolio? If it falls 50% and 3% of your portfolio is in the Bitcoin stuff, you just lost 1.5%. Maybe not a lot for small hobbyist investors, but it definitely is a lot for larger ones.
So... Basically I don't get the point of this... Everything can reduce the risk of your portfolio, just as everything can increase the risk of your portfolio. I don't see how Bitcoin can only "reduce the risk" or if it does not only reduce the risk, I don't get what is the point of this..
Correlation is cool and all, but it doesn't change the fact that the volatility of this thing neglects that correlation part.
When you put all your eggs on the same basket, you may lose all your eggs at once. Lets suppose you invest all your money in the US Stock Market, SP500. If there is some kind of crisis like 2008, you may lose 50% of your whole money overnight. But Bitcoin may not suffer 50%, it may even go up 10 %, or 30%. Or let's suppose you are a South Korean and you have 50% Korean Stocks and 50% bonds. If a north korean dictator throw a nuclear bomb on Seul, well, you lost all your money probably. Is South Korean riskier than BTC? Ofc not, but you are extremely exposed to one kind of risk. When you make a mix of different assets and get exposed to different risks, your overall portfolio becomes less riskier. Modern Portfolio Theory suggests that you make a geographical mix (stocks from many continents), diversify in bonds, real states, stocks, etf, physical assets (like a house), foreign currencies, even cryptocurrency. The idea is to reduce risk and reduce volatility of your overall portfolio. If you add High volatility assets to your portfolio, they may reduce your portfolio volatility.

This is where bitcoin comes in.
Bitcoin is a new asset class with high returns, non-correlated to any other assets.
In all you talked about I agreed. But not with the bitcoin. I do not believe that bitcoin gives high returns always. What about the high risk involved. Did you also calculate that risk that not so many people like bitcoin because of that and the case of volatility? Bitcoin is the asset with the biggest returns in the last 8years. I am satisfied with that valuation ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Encontrei esse topico, muito bom por sinal, do LoyceV, e resolvi escrever esse, com a mesma ideia. https://bitcointalk.org/index.php?topic=2848987.0 Inputs Outputs e UTXOQuem já está a algum tempo mexendo com BTC já percebeu que estamos em momento de baixas taxas. Como a maioria aqui sempre participam de campanhas de assinatura ou bounties, temos as vezes até dezenas de inputs em nossos endereços. No blockchain, na realidade, não existem endereços. Existem somente UTXO (Unspent Transaction Output). Cada pagamento recebido gera um UTXO, mesmo que tenham sido feitos para o mesmo endereço. Dessa forma, cada input na sua carteira custará uma taxa para ser movimentado. Porém, agora é um bom momento de juntar todos esses inputs em somente um output, economizando em taxas no futuro qd as taxas estiverem altas. Em dezembro, no auge das taxas, tivemos até 600 satoshi/byte. Hoje transações de até 10 satoshi por byte sao confirmadas em 1h. Voce pode verificar aqui: https://estimatefee.com/Por menos de 2 USD, e confirmação em 2 horas, é possivel consolidar até 20 inputs no mesmo output. Como fazer isso?Poucas carteiras são capazes de fazer isso. Na Electrum é bastante fácil. E também é possível usar electrum com a ledger nano s. Basta clicar em VIEW > COINS Selecione os inputs que você deseja consolidar, e clique em SPENT. Irá abrir automaticamente a tela de transação. Selecione um endereço da sua própria carteira e envie. Selecione taxas de acordo com o https://estimatefee.com/.

All good things must come to an end. Today marks 120 days since the merit system was introduced, and as Theymos said, old entries are going to start dropping off the file: https://bitcointalk.org/merit.txt.xzIf you want a complete list of merit entries, you now need to keep your own historical records. Oldest entries (120+ days) will also start disappear off of individual merit pages. This is sad. Merit could be like the blockchain, all merit transactions recorded forever ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

I see that many of you actually liked the concept of 20 % method wherein you allot 20% of your earnings to be saved as emergency fund. So I was thinking, if that 20% allotted will be invested in a time deposit kind of account, will it still be possible to earn as much or invest it in cryptocurrency? Or maybe just let the money sleep until such time you will need it? What will be a wise kove to do with the noney you have saved up?
Emergency fund should be just enough to pay all your costs to 3-6 months. After you build your emergency fund, you can to diversify your portfolio in Stocks, Bonds and even small amounts in crypto, depending on your risk appetite.

I wrote about this some time ago. https://bitcointalk.org/index.php?topic=3167859.msg32757342#msg32757342Bitcoin mining consumes a lot of energy. But it could hasten renewable energy adoption worldwide. Renewable energy equipment are expensive for households and the return of the initial investment takes too long. But if the excess energy produced can be directed to mining, the capital recovery can be hasten too. As it is profitable, it will lead people to buy more solar panels to mine bitcoin at their houses (They can't build a coal plant at their homes). As people are buying more solar panels, this will stimulate the research for more efficient and low cost solar panels. And, as many said before, the banking system consumes way more energy, and even Christmas lights consumes the same amount of energy.

Mais pra frente pretendo tentar mérito source... Acho que o alexrossi é um bom candidato tb
Até lá recomendo que vocês traduzam seus posts bons pro inglês pra pegar merits la..

Só vim aqui mendigar um merit mesmo, já aue estão distribuindo. Um dia, quem sabe, os adm's fiquem com pena e baixam os requisitos, vai que cola kkk
Pergunta: vocês conhecem alguém que saiu de full ou senior member desde que implantaram o sistema de merits?
Sai de zero pra 204. Jajá bato os 250 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Falta é activity... Pra ganhar merits precisa estudar sobre o BTC e escrever nas gringas. Aqui na aba local quase não existem discussões sobre BTC e tem menos merits circulando....

Technology in general always has it's downsides. On blockchain however, the downside is right infront of you. Due to the pseudo-anonymous nature of most cryptocurrencies, there are a lot of hackers and scammers that are taking advantage of this characteristic. Causing them to get away easily with huge heists if they do their opsec right.
Cash is anonymous too. Even more anonymous than BTC. BTC is somewhat anonymous, but you can be easily tracked, unless you use a coinmix service.
