3441  Local / Brasil / Re: Medo de perder os BTC on: November 23, 2022, 09:27:48 PM
por isso mesmo quero saber qual melhor wallet

Bem vindo ao forum.

Vc ainda é muito iniciante,  não olhe o bitcoin Core agora. Ele precisa sincronizar centenas de gb de blockchain,  não é o seu caso pra sua necessidade.

A melhor carteira que tem pra usar somente bitcoin é a electrum.  Baixe em electrum.org

Essa carteira tem o código aberto e não tem riscos dela parar de funcionar ou algo do tipo.

Gere sua seed na electrum mesmo, numa carteira nova, e transfira os seus bitcoin pra lá.

Não use bitadress nem nenhum outro site para gerar sua carteira.

Você está no caminho certo, não deixe nada em nenhuma exchange

Such an irresponsible public statement from an influential person who has millions of followers could cause massive trust and confidence issues and, therefore, a huge and sudden exchange run.

Irresponsible? It's calculated and many could argue that such statements, which call for transparency are good. Such calls, that can make more people secure their funds in their own custody, are good for the users (as long as they do manage to withdraw).
But fake calls can ruin his "golden aura" sooner or later and he may lose credibility, followers, ... so he cannot do this for too many times, and I am sure he knows that. I would not be overly worried.

I think tweet from CZ was not ethical. He was showing number from 2 different news websites,  which could be wrong (and they were). Those are not official number of coinbase (which is an open company listed in stock exchanges,  way more transparent than binance).

He was spreading fud against one of his main competitors using wrong data.

So my question boils down to: are cryptocurrency mining machines really real?  I need answers. How do I know what to trust?!

Your whole story is just a scam.

About your question: yes, mining is real. You can mine bitcoin while you sleep.
But you need to pay for the electricity and for the hardware . And they are both expensive

No free lunch .

Adciona a fonte do artigo pra evitar problema
https://livecoins.com.br/bancos-proibem-compra-de-criptomoedas/





Como justificativa, o banco disse que quer "proteger seus clientes". Eles comentaram:

Depois do estado babá, temos o banco babá.
"Não permitimos que voce gaste seu dinheiro com isso. É pro seu bem e a sua segurança.  Sabemos o que ébom pra você "

É justamente por isso que o bitcoin existe. Permitionless
3445  Local / Português (Portuguese) / Re: Maior banco do Brasil, o Itaú, vai custodiar criptomoedas em 2023 on: November 23, 2022, 04:22:20 PM
Uma coisa que eu não vi abordado é: o valor depositado em cripto fica protegido pelos fundos dos reguladores, caso o banco vá a falecia ou algo do género?

Em Portugal, os depósitos até 100.000€ esta assegurados, em caso de uma falência do banco. No caso do Brasil, qual é o valor? E as criptos depositadas, terão essa proteção?

Outra questão: qual é a vantagem para o utilizador depositar cripto no banco?



no Brasil é até 250 mil reais, como o TryNinja comentou.
não sei se cobririam crypto, teria que ler as entrelinhas e regras de cada produto.

julgo que não mas vai saber.

O fgc, o fundo garantidor de crédito,, é bastante restrito e tem muitas regras.
As principais são: apenas para alguns produtos bancários (cdb lca lci basicamente) e para até 250mil por instituição financeira.


São em geral produtos que incentivam o desenvolvimento do país. Como letras fde crédito agropecuário (lca) e imobiliário (lci), setores fundamentais da economia brasileira . Ou seja, o fundo estimula o desenvolvimento desses setores.

Criptos nunca serão garantidas pelo fgc, não existe a menor possibilidade disso.
3446  Local / Português (Portuguese) / Re: FTX entra com pedido de falência on: November 23, 2022, 02:02:13 PM
imagino que as principais vantagens da FTX e da binance frente às corretoras Brasileiras eram:
- taxas de saque mais baratas ou zeradas
- taxas de trade menores
- maior volume
- maior diversidade de produtos (contratos, altcoins, etc..)

A novadax é uma das maiores do país , acho q principalmente pq oferece muitas altcoins, mais de 100 na plataforma deles.

Isso até melhorou de forma geral tb, o mercado bitcoin e a fozbit oferecem muitos pares tb

O volume  nao acho q seja um problema para os principais pares nas grandes brasileiras. E para aumentar isso, não é uma decisão, precisa atrair mais clientes...

The problem is I don't have confidence in my work I know I have improved there are many more skilled artists than me. But I have to earn money and don't know as of now How much people will pay and accept my artwork.

Why don't you show your work here?

Do you work with front end, or just logo?

Maybe you should try to expand your abilities and try many types of designs,  maybe even create a website to show your portfolio.

Working for free is a good idea, specially if you need a portfolio and experience.

I created the website in my profile just to learn, it was like working for free. A few months later I joined a bigger projects and made some bucks.

Pessoalmente estou indeciso em comprar o Ledger ou não.

Pq indeciso?
É a mais barata e certamente entre as melhores do mercado.
Eu tenho uma e só tenho elogios.

A Ledger oferece $30 ou $20 em BTC, na compra de um dos seus modelos:
https://shop.ledger.com/pages/black-friday

Fique atento que essa promoção é pior do que parece.
Você vai receber bitcoin de um terceiro.  Não ficou claro que tipo de condições serão exigidas para receber esses 30 usd, mas ppde ser necessário fazer kyc

02
When your Ledger Nano arrives, the package will include your personal BTC gift card.
03
Follow the instructions on the physical BTC gift card to redeem your BTC on the Ledger Live app.

Que instruções serão essas?
De qq forma, vale 79 numa Ledger.

If you want to have success in your investments,  you should never try to predict anything.

Predictions are basically all wrong. Nobody knows the future.

So, just buy bitcoin for the long run and do ot try to predict the price for next year. Do not try to make an easy and quick buck, but most of times this fails.
3450  Economy / Service Discussion / Re: Coin market cap launches proof of reserves tracker for exchanges. on: November 22, 2022, 10:04:42 PM
This will lead to a false sense of security: you can't know how much is in the users' balances, so you can't know if the exchange has enough funds to cover them.

This is the main problem with proof of reserves.
It is fundamentally wrong, as you cannot really prove anything with it.

At most, some third party  Auditor will verify it, but then we would be trusting him.

A qualidade está muito boa

Isso é muito bacana. Eu fiquei bastante chateado nas olimpíadas que era impossível assistir qualquer coisa sem pagar uma TV a cabo.

Eu não tenho TV em casa, somente o aparelho, não pago net, claro, essas paradas, e não pude assistir nada das olimpiadas. Não tinha nada no youtube nem lugar nenhum.

Das outras vezes eu sempre conseguia assistir na TV aberta alguma coisa, mas dessa vez não deu.

Vou fazer o meu e postar aqui tb. Eu curto muito o reddit,  boas fontes de informação lá.

Só fico com o pé meio atrás nesses NFTs de rede social, pq é uma invasão grande na privacidade,  quando vc linka seu endereço eth a sua conta. Mas, é só não colocar no seu main address né.

3453  Economy / Scam Accusations / Re: ViperSoftX - A new Trojan that steals cryptocurrencies through a Chrome extensio on: November 22, 2022, 01:23:57 PM
What are we seeing? Again, Windows systems and the Chrome browser Everyone is strongly advised to start studying Linux systems and not to trust this browser and, even more, various extensions that supposedly simplify the work on the Internet.

I believe the problem is not with windows or the browser. The problem here is with the user.
Why install so many extensions? Everyone who cares about security and privacy should avoid installing extensions in their browser.

Everything you install in your computer or smartphone is potentially a spyware or a malware, i.e., it could be collecting your data (most of them do that) or just do bad things to your device.

Before installing anything, think twice if you really need that extension/app

Also does Tether (USDT) scare anyone?

BIg stable coins looks safer than in the past. USDT, USDC and BUSD now have regular audits and there is much more regulation over those coins.

For example, take a look at tether transparency:

3455  Economy / Economics / Re: Ontario Teacher's Pension Plan accepts their loss on: November 22, 2022, 02:06:04 AM
When crypto was first introduced into the finance world there was something called cold wallets which were used to prevent these types of hacks. If we want a legitimate discussion we can pose a question of why crypto finance which was founded upon principles of reliability and durability drifted away from the use of cold wallets as a standard protocol.

I believe the main reason for this is that investors are not satisfied with bitcoin gains. "Crypto" became much more than holding bitcoin in a hardware wallet.

Those funds and even small investors prefer to buy exchange tokens like FTT and BNB. Or even worse, they put their bitcoins and tokens in an exchange wallet to get 4% APR.

Sometimes those exchange go bankrupt, and their bitcoins and crypto are gone for good, for such thing as little a 4% APR.
3456  Economy / Services / Re: [OPEN] Professinal and experienced web developer needed on: November 21, 2022, 11:43:00 PM
Main site is https://sinbad.io
(bitcoin mixer, the site in fully functional and they are running a signature campaign already on bitcointalk)

Since the current design looks very poor, my client already hired a front end developer to redesign the site. It's in progress and can be seen on here: <sill be shared on PM>

Now, we are looking for someone who will be very professional to apply the current functionality (sinbad.io) to the new design and install the entire site again on the main domain. If you have done such work before (it does not have to be a mixer only) and have huge experience in web development, then please contact me.

Let's discuss how much it will cost and if the client agree then I will secure your payment before starting the job.

Well, I am not experienced but I can work with front-end development. I have some experience with React framework.

I have this old job https://bitcoindata.science which was designed with vanila javascript. I can do better work nowadays (I prefer not to share my recent portfolio due to privacy concerns)

Depending on what you need, I can do the job. We can discuss in PM if you are interested.

3458  Bitcoin / Hardware wallets / Re: Ledger: get up to 30$ in free BTC. on: November 21, 2022, 07:52:09 PM

Anyone considering taking advantage of this promotion should know that the bitcoins are sent by a 3rd-party Ledger service provider. If this party determines a need to undergo KYC, the user might be required to verify their identity before receiving their coins.

If it weren’t for the possibility of being asked to undergo KYC, I would say this is an interesting offer. But I’m not too fond of it. I also don’t know if Ledger can demask users and connect the names from order data with the codes that get claimed. It would be easier if they offered a $20 and $30 discount on their respective hardware wallets. My guess is they didn’t care to think of something better. They have already said they are getting 7x more sales following the downfall of FTX, so I assume they have already filled their pockets plenty. 

Financially  , they could just give a $30 discount that ot would be the same.
However,  there are still people who thinks that receiving their first btc is exciting and things like that. This is an interesting marketing.

I agree 100% with you that doing kyc for 20 - 30 is not ok. Customers already did enough identification to receive the product at home, shipping address name etc... no need to give further documents which are useless for the bitcoin transaction
 Additionally,  ledger does not handle sensitive data very well.
3459  Other / Off-topic / Re: Do you agree that an employer should hire employees who are smarter than him? on: November 21, 2022, 06:45:52 PM
I was listening to a YouTube video by a famous business man and he was saying that he prefers to hire employees who are smarter than him. Do you agree with this style of working? What are the possible intentions behind doing this? Isn't their fear that these smart employees can steal ideas from office or get client details and then start their own companies? What is your view regarding this?

Life is not so linear. There isn't such thing as a smart number and people are like in a line over that.

People have different qualities and know about different subjects. Someone may be very smart in coding but an idiot when talking about finances or administration (like Sam from ftx) Nobody can be smart in everything.

So, a boss should always hire people who are smarter than him in various area where he is not or just doesn't have time

Tesouro direto já com taxas acima de 6,0% e com várias paralisações consecutivas, lá vamos nós pra renda fixa novamente

O gigante acordou  Cheesy

Comprei até 6.16 esses dias.

Em Portugal, apesar do aumento das taxas de juros, os bancos não estão a "dar" nenhum valor para ter o dinheiro depositado.
Gradualmente, já começam a surgir algumas vozes a dizer que o governo deveria interferir.

Dinheiro parado na conta aqui tb não rende.
O que rende são os depósitos bancários a prazo. Eu vi aqui e tb existe isso em Portugal, mas rende menos:
https://www.novobanco.pt/particulares/poupancas/todos-os-depositos-a-prazo

O que acontece no Brasil é que existe uma situação muito específica aqui. Nos temos as taxas de juros entre as mais altas do mundo, pois nosso governo historicamente gasta mais do que arrecada, e precisa rolar a divida a todo momento (literalmente) pois estamos sempre com déficit anual (em teoria, esse dinheiro deveria ir ajudar os pobres que são maioria e elegem o presidente)

Como o tesouro nacional, ou seja, o Estado, é visto como mau pagador e precisa pegar dinheiro emprestado a juros altos, os banco são formados a pegar emprestado mais caro ainda (se não ngm empresta pra eles)
