em relaçao a taxação so espero que nao seja tao abusiva como as dos jogos da santa casa, pois quem faz alguns trocos so para ir jantar fora com a familia em minerar, etc etc... deija de ser rentavel!

Ui, espera para ver... Imaginação não lhes falta para tentarem sacar tudo. Aquela história de teres de pagar obrigatoriamente o milhões não passa de um imposto.

Este governo tem sido pródigo em criar impostos... Até já exporta!

There's just one cause of death: Life.

Live as it fits you, life can't be a condemnation where you've to be alive even if you are doing things that gives you no joy at all of living.

Adding some deepness to this:

1st there's no such thing as "be poor" or "be rich", one either "feels" one way or another. You can find people feeling rich for having food for the week, and another feeling poor because can't buy a new iPhone, despite having food in stock for years.
This leads to the relativity of the issue: what is it to you to be poor? Or rich?

Do you know what the impact is on transaction fees if you combine multiple outputs from multiple addresses compared to multiple outputs from a single address? Would there be a difference in transaction size if they originate from multiple addresses or is it only related to the number of incoming transactions that now need to be pooled?

Yes, it has an impact on the tx size, therefore you'll pay higher fees if you store small amounts through multiple addresses. Each address has an unique private key, those coins are associated to that private key, so each input has to be signed by it.
If you've 1 BTC stored through addresses A to J each with 0.1 BTC, when you send 1 BTC to someone it will have 10 inputs -> 1 output, making a much bigger tx in size than if you've 1 BTC at a single address.

The concerns of privacy on opposing end is that, if you have too many coins stored at a single address, you will undisclose your whole amount upon a tx.
If you've 1000 BTC at a single address and want to send 1 BTC to someone, it will cause 1 tx of 1 input (1000 BTC) and 2 outputs (1 BTC to whoever you're sending + 999 BTC returning to your change address) - ignoring fees on the examples.

Thanks for the advice!!!
I wanted to use ledger nano address to withdraw from Hashflare, but if I change the wallet address, they don't send payout for 2 weeks.
So I thought I can't use ledger nano address for another payments, because if I use it, they change it.

So helpful this forum is.
Thanks so much.

Your old address will remain attached to your wallet. So you can send how many times you want to that address.
It will provide you a new address, but the old ones remain there. Means you can use it for that you want.

Also don't forget that each time you send Bitcoins your "change address" also changes, so probably you don't even know it.

Let's say you've 5 BTC at address A and want to send 3 BTC to address B.
Bitcoin can't split coins off-chain, so it has to send the whole 5 BTC and the thing will go like this:

Input from address A of 5 BTC with 2 outputs:
3 BTC to address B
2 BTC to address C, where address C is another address from your wallet that, depending on your client, you may not know yourself.

And then if you send 1 BTC to address D, the process will be:

1 input from C of 2 BTC with two outputs:
1 BTC to D
1 BTC to E, where E is another change address.... and so on, and so on.

Despite these change addresses aren't shown to you, your software has the proper private keys.

Não é uma visão contrária Pedro.
Não estou contra a taxação, estou contra o mediador voluntário que apareceu e a forma como o fez. Não sei se leste o artigo, mas aquilo era na base de "os consumidores exigem", intransigente, a fazer as contas a quanto o erário ganharia ou deixaria de ganhar, não sei se pensam que as Finanças estão com falta de pessoal ou quê.
De resto concordo contigo, a taxação seria a legalização tácita da BTC.
88  Local / Portugal / Re: Já começaram... on: February 13, 2018, 11:08:03 PM
Só te posso dizer que temos pontos de vista convergentes.
Acho que já disse aqui uma vez que para a maioria aquelas aplicações bancárias com seguro de risco incluído que pagam 0,001% ao ano já são risco demasiado, imagina a Bitcoin! Isto requer nervos de aço, se assim não fosse já tinha desbaratado as minhas precipício abaixo num daqueles dips > 90%.

A resposta da DECO à acusação de ter espetado a foice em seara alheia é doutro mundo!

Este foi o meu comentário:
Quote
Sucede que a DECO é uma associação de defesa do consumidor. Por conseguinte este artigo não faz sentido nenhum, já que em nada tem a ver com a sua suposta e declarada actividade.
Não é que seja contra a taxação, mas tal é para ser discutido em sede própria pelas partes que compõem, a AT e os investidores, não por terceiros não chamados a mediar coisa nenhuma e cujo o único argumento é o velho e desprezível "se eu me lixo quero que os outros se lixem também".

Em resposta deles:
Quote
Caro consumidor,

Os impostos, embora sejam vulgarmente vistos como apenas um encargo, são destinados a financiar as despesas do Estado nas suas várias áreas de atuação e das quais, em teoria, beneficia toda a sociedade portuguesa — onde também se enquadram os consumidores.
Nesse sentido, defendemos que o pagamento de impostos incida da forma mais equitativa possível sobre os contribuintes, pelo que propomos que os ganhos obtidos com a compra e venda de criptomoedas, sejam tratados, fiscalmente, da mesma forma que os lucros obtidos por outros investimentos, como por exemplo, a venda de ações ou os juros de depósitos bancários.
O nosso papel, também é o de lutar por situações que julgamos serem do interesse dos consumidores e contribuintes.

Recordamos algumas das ações em que tal sucede, como a relativa ao Imposto Municipal sobre Imóveis: www.paguemenosimi.pt ou aquela onde exigimos que os bancos não possam cobrar comissões que consideramos injustificadas: www.deco.proteste.pt/campanhas/comissoesfora.

Ora, começa pelo entendimento de uma criança de 5 anos da velha falácia "os impostos beneficiam todos"; isso só é verdade até certo ponto, não estamos na União Soviética nem na Venezuela para andar tudo a tentar viver à conta do Estado, com os resultados que se conhece.
Depois o argumento do "onde se incluem os consumidores"; bem, todos somos consumidores na mesma linha em que todos bebemos água (seja directa ou indirectamente), pela mesma linha de argumentos pode-se criar uma associação de defesa dos bebedores de água e a seguir meter o nariz em todo e qualquer assunto sob o pretexto que "também são bebedores de água".
Sem falar que o alívio que eles dizem ter recomendado é no IMI, que é um imposto municipal que nada tem a ver com o Estado central, ou na banca que não tem nada a ver com nada, já que é etérea a impostos.

Quote
O pensamento sobre os impostos, no ponto de vista do consumidor, deve assentar sobre uma melhor distribuição dos mesmos, uma distribuição mais equitativa do esforço global. Até esta parte estamos de acordo.
No entanto o artigo esquece-se que uma nova fonte de receita deve corresponder a um alívio em outra área, sob pena de tal resultar somente em aumento de despesa que por conseguinte resulta num aumento de endividamento por alavancagem e por conseguinte aumenta ainda mais os impostos (é, a economia tem 2 lados), é totalmente omisso em tal, é só o velho "se pago quero que os outro paguem" sem que se coloque sequer a hipótese de tal aumento de receita se prever ou recomendar alívio no que quer que seja.
Preconizando então que a DECO defende meramente um novo imposto, sem alívio ou distribuição de carga e sem interesse para os consumidores, acabando por colocar a foice em seara alheia.
Isto não significa que seja contra esse imposto ou eventual taxação desse ramo, a nota refere-se à entrada a pés juntos, plena de imperativos, sem que se lhe possa notar o real interesse do consumidor por parte de uma associação de consumidores.

I wouldn't say laziness, those people aren't exactly lazy but under bad management.
The child/slave labor at Bangladesh who made your clothes can't be called lazy, can it?
It depends still on the region we're talking, between tropics life is easy, terrains are fertile, so no much effort is needed. At some point you can blame laziness on these ones, but most just don't work more because they will be robbed if they do.
My father was working in an UN program for Mozambique and one farmer told him he wouldn't produce much because of the "evil eye". At first he though he was superstitious, but he came to realize what that means; if they produce too much, an army or paramilitary branch will show up to "collect protection", so keeping the production at "just enough" will get them out of troubles.
The whole mess appears to root from the lack of understanding that economy has to be distributed, otherwise you'll be building 10m+ USD luxury houses in the middle of "Favelas" and can't show your face in the street... but greed doesn't let many to clearly see the whole picture nor the "price of their money".
91  Other / Politics & Society / Re: What is the common cause of poverty? on: February 12, 2018, 02:17:55 PM
There's no such cause, poverty happens naturally. Just sit on your ass and do nothing and it will come to you.
Wealth is what requires work and something to cause it, poverty doesn't.

It's somewhat awkward that the poorest places are the naturally richer ones, but when the world let you live with minimum effort that's what you do, and by doing as little as possible poverty will find its way.

I can highlight 5 causes of poverty:
1 History
Many of the poorest nations in the world were former colonies from which slaves and resources had been systematically extracted for the benefit of colonizing countries.

Not really. They still have most of the resources and slaves, actually even more slaves than ever. But it doesn't make any difference when the management is what it is.
92  Bitcoin / Bitcoin Technical Support / Re: I found a collision. The hard part is proving it. on: February 12, 2018, 12:55:55 PM
Yes, it's possible. Unlikely means it still can happen, just like life on earth.
However to prove collision one has to have both private keys and those private keys have to be different. If you've just one than most likely your seed is the same used to generate the other, so you got his private key, not a collision.
This said, unless you find the owner of those coins and he comes forward with a different private key, there's nothing to see here.

You pay what market decides these services are actually worth at any given moment.

Reason why its value isn't the same everywhere. The labor theory is still under the relativity of value umbrella.
94  Economy / Economics / Re: The intrinsic fallacy on: February 08, 2018, 01:15:05 PM
On utility basis, silver would be way more valuable than gold. Gold is just used for plate (with a tiny micron think layer) exposed contacts, due to its oxide-resistant properties whereas silver is the best conductive bare metal known.
Due to its value, gold jewelry is on a nose dive for quite a while now. Too risky to carry around such value on display.

That's not a collision, that's just what it; brutte-force.
96  Economy / Economics / Re: The intrinsic fallacy on: February 08, 2018, 11:59:31 AM
You get the word "intrinsic" out of context. Economists and other experts refer to the word "intrinsic" as its tradable value. Like a gold can be traded into a land or a property or others. Unlike bitcoin, it has no intrinsic value. Its value is merely derived from supply and demand and its foundation that pushes supply and demand to the right is pure speculation. You have to understand the words can mean differently in different disciplines and you should take words into context.


If the counterpart doesn't accept gold you get nothing.
Gold is just as tradable as Bitcoin and its value derives of supply and demand just like Bitcoin... most of people also does nothing with gold, just stores and holds it as bars in speculative hope of its value to go up.

What you're mistaken is physical existence, you're saying that "you can touch it so it has some value". Well... you never touched a single dollar or whatever currency you use, coins and notes are not physical money, they are just physical representations of it, yet you use it.
97  Economy / Economics / Re: The intrinsic fallacy on: February 08, 2018, 11:51:51 AM
No argue there; fiat has the intrinsic properties of paper: means you can write on it and it burns quite easily. Still most of it is virtual and has no intrinsic anything.
However time is an absolute value, you live x years, not x dollars and they aren't correlated. You can take a longer time than me to do something or vice-versa, and this will just means you will earn/create less "value" per hour (or other time frame) than me. How hard it is or not to create also won't define value, the hardest thing to do if has no demand still has no value.

On the other hand you're mistaken value with money, money is just one way to express value, an abstract layer to quantify somehow the value, but value itself isn't money. You can choose to provide a service or goods of equal or equivalent "value" without express it on any currency.
98  Economy / Economics / Re: The intrinsic fallacy on: February 08, 2018, 09:57:11 AM
There you get a paradox: air and water.
You can imply it has always some value, so that value is intrinsic. But water and air are vital, and here comes the paradox: water and air aren't charged anywhere.
Yes, they are free, practically everywhere. What is charged is the service of treat and bring water to your tap or bottle it, not the content. It would be highly immoral to charge for water because those unable to pay it would simply die.

So paradoxically what holds more value, vital value, can't be charged at all.
99  Economy / Economics / Re: The intrinsic fallacy on: February 07, 2018, 10:48:15 PM
There's nothing more annoying than keep listening to some idiots, and idiots that are supposed to know what they are talking about, speaking about "intrinsic value".
Let's put this straight once and for all:

There's no such thing as intrinsic value!

Intrinsic means something a thing has on its own, regardless of human intervention. What things have is intrinsic properties; gold has the intrinsic property of resisting erosion, copper has the intrinsic property of conduct electricity, and so on. But none has value on its own.

Value is always attributed, never intrinsic!

I think to argue that nothing has an intrinsic value is incorrect. Take water for example, that definitely has intrinsic value to us as humans as without it we would not survive.

The specific value we assign to things is where the confusion comes in, water could be worth 1c or 1 million depending on who you were offering it to and their circumstances. Nothing has a set value and that value is always defined by our perceptions and our needs.

Water itself has no intrinsic value, but the intrinsic property of satisfy thirst. It may worth a million at a desert but nothing during a flood.
100  Economy / Economics / Re: The intrinsic fallacy on: February 07, 2018, 07:27:08 PM
And so what? Did just read about the subjective theory of value or something?

Not about that, but lately every time a jackboot tries to jump on Bitcoin will always come with that "intrinsic value" thing...  Roll Eyes
