Market is recovering, but many altcoins are not. It's possible that some of them never will.
Few altcoins have survived the long term.

That's why it's important to make a long term portfolio with the market leaders, mostly bitcoin and ethereum. I don't like ripple but it's a good choice for long term too.

As you are going down the coinmarketcap the risk is higher. That's why people who invest (and even overinvestment sometimes) in those coins and get worried.

It seems to me, that blockchain could help developing countries, but instead of it India forbids bitcoin Huh

That's the exactly problem with developing countries.
Solutions are banned, government controls everything. There's a legion of idiots and paid idiots that supports every government decision.

Look at Brazilian central bank president. And there's a bunch of people who supports him.

Sorry if this is a very dumb question, but can you help me understand the "longest chain" is the valid chain concept? This is something I'm confused about when it comes to bcash, as it is currently the longer chain. Is it because these are two separate coins at this point? Or does the "Longest chain" refer to mined blocks that become orphaned?

Bcash is another coin, no matter how long that chain is. It has nothing to do with bitcoin.

Muito obrigado pela contribuição.
Me resta saber se eu tinha, na epoca dos forks, algo que valha expor minha seed, mover os fundos e criar outra carteira.
Eu nao lembro kkkkk

Question No. 3

Is Bitcoin vulnerable to quantum computing?
Code:
Answer:

Not really. The could solve proof of work faster, but the puzzle difficult can be increased.

The biggest threat is that they could break public keys cryptography and discover the privatekey.

According to some articles that would need high investment and would still take decades to make this a low cost operation. By that time cryptography is going to develop better signatures schemes too.

Its so funny to see how people changes their minds so easily... when BTX went form 5 to 30 USD, people were expecting to see hundreds in few months.... Than the price dropped and everyone was like noo, its gonna be 1 dollar, we are screwed... and now, we see the price growing again and everyone has their minds in the clouds again. Seeing for sure those thousands of dollars prices and lambos all over the place...


Buy high sell low mentallity. If you believe the project, just hodl and you will never lose.
Don't get overinvested, so you won't get worried.

Misconception #8. Bitcoin is free. Wrong

Bitcoin is not free. As other currencies bitcoin is " Crypto Currency " but it is not free. Yes you can get it by many means some famous are (faucets, mining, etc). But its not free you are investing your money and time on Machine , internet and work which you provides to get.


I saw this picture recently.
Cost to mine 1 bitcoin is pretty high around the world, with very few exceptions.

O gráfico começa em 1000% pq se existem 10 BTC no mundo no primeiro dia, dia seguinte tem 20. Tivemos 100% de inflação em 1 dia.se existem 10 BTC e 1 ano depois temos 100 , 1000%...

Agora entendi sua dúvida. Pq se a recompensa é fixa o gráfico varia?

Por mais que a recompensa do bloco não varie diariamente, o tempo para minerar o bloco varia sempre.

A dificuldade é ajustada para que com a atual capacidade de processamento o nonce seja encontrado em 10 minutos, estatisticamente. Mas não existe um nonce que cai do céu em 10min.

Se um minerador der sorte pode minerar o bloco em 1 segundo, ou o bloco pode demorar 15 min se todo mundo estiver azarado. Por isso temos essas variações. E esta bastante estável a linha no final mesmo, com a recompensa fixa
12575  Local / Criptomoedas Alternativas / Proof of Stake e o Ethereum Casper on: April 20, 2018, 05:37:25 PM
Proof of Stake (PoS)

PoS funciona de forma diferente do Proof of Work, mas com o mesmo objetivo.

No PoS não existe mineração. O consenso sobre as transações é atingido por meio de investidores com alto percentual de moedas.

Em um blockchain que utilize o algoritmo PoS, os validadores afirmam que determinadas transações são validas. Como garantia, enviam suas moedas (stake) em uma transação especial. O stake dele fica preso até o final da validação do bloco. Se o bloco contém transações inválidas, eles perdem as moedas.

Quando o bloco com as transações validas,  onde ocorreu o consenso, é validado, um novo bloco é criado. A recompensa daquele bloco é dividida entre os validadores que "apostaram" naquelas transacoes daquele bloco.

Stake em ingles tem vários significados: aposta, garantia, participação economica, conjunto de itens....
    
Ethereum Casper

Ethereum casper será a aplicação do algoritmo PoS, em conjunto com o PoW, no Ethereum.
A cada 50 blocos minerados com PoW, um bloco será validado com PoS. Esse será o começo do Etehreum Casper, em um processo gradual até um aumento mais significativo do PoS na rede.

These are shitcoins
People will get Airdrops that will be worth almost zero. Or they will worth few bucks and become zero in few months.
They are not a threat to bitcoin.

And if any altcoin show some good code improvement, bitcoin can just copy it if it's good.
Bitcoin can coexist with other coins as well, as windows Linux Mac and Android do.

you dont get the point, they will also attract attention and therefore distort and confuse attention for Bitcoin

coins without missions will be just advertised datasmog.

Do you buy everything from an ad you see in the internet or in the streets?

Eu não acredito nos números dos governos Tongue

Como é feito o calculo desse site? Dei um zoom e vi que a inflação sobe e desce (não é algo fixo como eu pensei que fosse caso a inflação fosse baseada na recompensa dos blocos), e também não é baseada no poder de compra, já que em dezembro de 2017 a inflação estava maior do que agora(na verdade estava igual, 4,32%) porém dava pra comprar mais coisas com o mesmo "1 BTC"

Provavelmente o cálculo do site é feito baseado na taxa de emissão de Bitcoins. 4% de inflação significa que são emitidos 4% de novos bitcoina por ano (sobre o total atual).
Daria em torno de 650.000 novos btcs por ano, o que acho bem razoável e foi o que eu observei, já estamos perto dos 17mi.

A inflação não é fixa pq a recompensa dos blocos não é fixa ué.

lembra em 2011 que vc mineração 50 BTC num notebook em casa? Tenta fazer isso hj rsrs

A dificuldade vai aumentando... dificuldade aumentar significa achar um número cada vez menr no nonce. Antigamente o número não era tão pequeno, é hoje é muito pequeno.estimam que o último milhao de btc demorará décadas para ser minerado.

Escrevi sobre isso nesse post https://bitcointalk.org/index.php?topic=3309188.0;topicseen
Tudo tirado do whitepaper do btc.

Baseado nisso tudo, a emissão de Bitcoins hoje é maior do que a emissão média pelos países no mundo
