There are many app which track balances of a variety of assets like blockfolio and many others. But imo all those apps are good only for newbies. Veterans already have a 100% bitcoin portfolio , or close to that  |

I made a little research about it, and it is a bit more complicated. Satoshi didnt invent blockchain, but he created the first blockchain. Those people you mentioned just wanted to create one, but thy didn't. "The first work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta.[6][11] They wanted to implement a system where document timestamps could not be tampered with. In 1992, Bayer, Haber and Stornetta incorporated Merkle trees to the design, which improved its efficiency by allowing several document certificates to be collected into one block.[6][12] The first blockchain was conceptualized by a person (or group of people) known as Satoshi Nakamoto in 2008." https://en.m.wikipedia.org/wiki/Blockchain |

My recommendation is to stay away from all those websites.
Stay in bitcointalk, read what people say here (more than you write) and in a few months you may earn a few bitcoins as a beginner, here.

Considering how many people use bitcoin 11000 is not that big number i though it should be at least 30k. That's why im running one full node 24/7 for a few monts now and i'm planning to set up sometime soon a second one. We need decentralization.  There are much more than 10k nodes, as ETFBitcoin said. You can only view full nodes that accept incoming connection. |

If someone have more than 51% of the hash rate, can't take the control of network and change transactions?
I know that's very difficult since it needs a very very big computing power. Once a transaction is changed, the hash of that block and all following blocks are changed and proof of work problem of all of them must be solved again. But isn't it at least theoretically possible ?
Only recent transactions, from the most recent mined blocks. The attacker must mine a previous block and outpasse the whole hash rate mining new blocks in his alternative chain until he passes and his chain becomes the longest. So, this cannot be done in a transaction which already has 50 confirmations. For practical purposes, a transaction with 6 confirmations is already considered irreversible |

Performing any KYC anywhere is risky enough. But giving out every single detail of your life, including your employment history and a sample of signature is just asking to have your identity stolen, especially when Coinmama reserve the right to give all that information to anyone they please. Especially when considering the growth of fast and secure decentralized exchanges and other methods which don't require KYC, I wouldn't be touching Coinmama from behind 7 proxies.
This is certainly absurd, and as no one ever reads any privacy policy, we just click ok and they do that .. Have you ever read similar documents related to your bank account? I opened a new bank account in the largest bank in Brazil, and I was choked. Basically, I signed a lot of papers saying that the money is not mine anymore, that they can do with it whatever they pleased and I could not complain. I showed that to the manager and he just laughed and said it was like standard and I shouldn't worry lol I signed and left lol
On topic I think coinmama and cex.io are the most common used to buy btc with credit card... I wouldn't use local bitcoins because the risk of losing money is higher. |

Blockchain is a technology which was designed by satoshi nakamoto, when he created bitcoin.
If you want to create a project regarding those disciplines, you should at least read some books related to the subject
The best one for beginner is mastering bitcoin by Andreas Antonopoulos.
You can find it for free in github.

Gostei da ideia, comparando o consumo de energia do btc com o de outros setores , principalmente o ouro.
Pow é sem dúvida o que torna o btc valioso. É o alto custo de um ataque o que torna a rede segura. E o custo da energia da mineração atrela o preço do Bitcoin a um ativo real, quase lastreia o Bitcoin ao custo da energia pra minerar. Coloca um pé do Bitcoin no mundo real.
Quanto a sua pergunta, esses protocolos alternativos todos são um fracasso total. Pos, tangle, etc são apenas um conjunto de boas intenções que nunca são aplicados em larga escala (como no caso do eth q até hj não implementaram pos ). Na verdade não sei nem dizer se são de fato boas intenções mesmo, ou se só querem pegar $ de desinformados...

A trezor tem uma vulnerabilidade dessas que não tem correção e foi encontrada pela equipe da ledger. A única forma de se proteger mesmo é usando passphrase. Mas sinceramente, esse tipo de ataque em que um hacker precisa de acesso físico ao dispositivo é coisa de cinema... https://donjon.ledger.com/Unfixable-Key-Extraction-Attack-on-Trezor/Eu sempre preferi a ledger pq é mais barato, agora ainda com esse bug incurável... |

Is all of them forks from bitcoin and there to be claimed?
Most of the forks are not worth claiming anymore. And soon as new fork shows up you should trade it for btc, immediately. There were many forks which had some significant btc value, but they are now worthless. Like bitcoin diamond, bitcoin x, bitcoin core, bitcoin atom,bitcoin private etc... You could get more than 100-300 usd for each btc you had. Now they are worth nothing anymore and I don't recommend claiming them. |

Se ele for aceito em várias exchanges, você pode fazer arbitragem de forma rápida e potencialmente com taxas baixas. BTC -> BRLT, envia para outra exchange, BRLT -> BTC (BRLT = stablecoin em Real).
Pois é, mas Dificilmente essa moeda do mercado btc seria aceita tão amplamente... quem sabe. E o spread de arbitragem anda muito ruim, sinceramente acho q nem vale a pena.. nem internacional |

Essa questão de fungibilidade e de marcar moedas oriudas de mixer é antiga. Um tempo atrás vi um post do antonopoulos sobre isso. Algumas Exchange dizem que suas moedas não servem, que estão "tainted" pq vieram de um mixer (o que é razoavelmente fácil de identificar). O negócio é que se você olhar pra trás indefinidamente, a maior parte das moedas já passaram um dia por um mixer (umas mais recentes do que putras) O que ele sugere é que se você tiver esse problema, faça umas 10 transações internas na sua carteira, para outros endereços seus. Pq uma Exchange deve ver um limite máximo de transações pra trás, umas 5 ou 10 somente. Acho a foi esse vídeo https://m.youtube.com/watch?v=BILcJ3WtdLQ |

You are really an weird case.
You have zero merits, and you put so much effort in your post. There is no plagiarism as long as I could find.
Then I checked your post history, you have only bounty reports in your history.
Why don't you try to act more naturally here? Try to engage in some discussion, and contribute to it.
Your post has zero content... although I would like to give you some merits, this is not the way imo.
Everything you said is repeated all over the forum, and the merit system was implemented so that users who are solely bounty hunters could not rank up. Which is your case.

Nao Viejo vantagem absolutamente nenhuma em um brasileiro usar uma altcoins lastreada em reais. Em tether até faz algum sentido, pois tem Exchange como a binance que não aceitam usd nem brl... Comprar uma altcoin lastreada em real é literalmente um empréstimo a juros 0 para um provável mal pagador. Quem sa consciência faria isso? Ainda amais com o histórico de golpistas relacionados a esse setor no nosso país e no mundo Quer emprestar dinheiro pra alguém? Renda fixa. |

If anyone can double spend from this wallet they get 5 bsv.
Your private keys leaked somehow. No miner can help you. No one can double spend coins. Nobody will reverse an already 73 confirmation transaction, specially for such low 0.02 bsv As far as I understand your problem is simple that you received some coins to an address which someone else also has the private keys. Did you generate that private key by yourself? Were you using some online mining tool? You were probably scammed by someone. Do not use any other address from that wallet. Uninstall this wallet . |

Well surprise surprise! There's only going to be more forks from here. I don't know why it's a big deal for you though. All of Bitcoin's forks are pretty much irrelevant anyway. And what do you expect? The code-base is open source. Forks are pretty much inevitable simply due to the fact that Bitcoin is open-source.
Pro-tip for you: just ignore the shitcoins.
That is not entirely true. Many of those forks were worth recovering if you were fast enough, if you have at least 1 BTC (which I believe is the case of most users here) I recovered bitcoin diamond, bitcoin core, bitcoinx , bitcoin atom, and others which I can't remember now There are even some airdrops like semux (which pays if you sign a message with btc balance) which are worth. For all those I received something like 100 usd at least for each btc, maybe even more. But just when they are released, because shitcoins lose value over time... |
