Mas na prática, eu nunca entendi o que era o USD da FTX por exemplo. O que eles fazem é ter um pouco de todas? A % é definida de acordo com alguma regra? Que eu saiba não tem regra. É simplesmente um monte de stable coins. Muitas exchanges fazem isso, como a bitso. Isso é uma solução pro problema de liquidez de stablecoins específicos. E no caso da Binance, ai acontece que o BUSD é uma cesta de todas as stablecoins que existem também + outros papeis e é simplesmente uma forma de fortalecer a propria moeda na forma como expoe para os usuários ou não tem incluso outras stablecoins dentro da BUSD?
No caso da binance, ela não vai aceitar outras. Não tem cesta. É simplesmente a stablecoin dela, a bsud |

Not to mention that large corporations (like centralized exchanges) suddenly gain power over the protocol, besides their financial power.
Exchanges are very susceptible to regulations and authorities, which can simple force them to apply to whatever any government demands or they just shut them down. Recently, Vitalik buterin was proposing high punish for exchanges that block address or do any other misbehave. He suggested that at the protocol level the staked coins from the attacker are destroyed. This is specially interesting if exchange are forced to apply to authorities. The only alternative left for them would be to not offer staking server, and their coins will be just sit in the exchange (not participating in PoS, because they risk losing their stake if authorities force them to do anything that the protocol do not permit, such as blocking address or coins)  https://twitter.com/ercwl/status/1559268027983593474/photo/2Anyway, let's see if such things will be implemented or not. |

You have to trust the staking pool to return your coins eventually (once unstaking has become possible, that is). And going solo is prohibited by design unless you have at least 32 ETH in the bank.
Not necessarily trust, it can be trustless managed by a smartcontract. Some pools operate using smart contracts, where funds can be deposited to a contract, which trustlessly manages and tracks your stake, and issues you a token that represents this value. Other pools may not involve smart contracts and are instead mediated off-chain. https://ethereum.org/en/staking/pools/I believe there are other problems with PoS, but not about the staking itself, which can be secure and trustless (it is just a decentralized contract that manages the coins). The problems are the ones mentioned by BlackHatCoiner, and specially the decentralization problem related to coin distribution and censorship resistance (holders may be just forced by authorities to take some protocol decisions) . |

Pelo que eu estou vendo nas notícias, deve rolar um hardfork. Li na coindesk que estão esperando um valor baixo, em torno de 20 USD para cada ETHPOW. Potential Ethereum Hard Fork Token ETHPOW May Trade at 1.5% of Ether's Price, Futures Suggest
Paradigm expects the token will open at least $18.
...
"We can infer how much the market estimates ETHPOW will be worth from simply looking at spot-future basis, since spot = PoS + PoW, while future is just PoS," Paradigm said in a Merge-focused blog post published Wednesday. "Currently, the basis is implying ETHPOW to be priced ~$18, which is ~1.5% of ETH market cap." Deve cair um trocado então para cada holder de ETH. |

As the "arms race" escalated from single to multiple CPUs, and then to GPUs and on to ASICs, it becomes more and more costly for the average network participant to get involved with mining. Many would now consider it an unaffordable endeavour.
Ironically the minimum staking requirements that come with most PoS schemes makes the barrier for entry even higher than PoW. Not exactly. Although there is a minimum 32 ETH to become a validator, you can join a pool with basically any value. Low barrier to entry Not a whale? No problem. Most staking pools let you stake virtually any amount of ETH by joining forces with other stakers, unlike staking solo which requires 32 ETH. https://ethereum.org/en/staking/pools/You can see in ethereum.org website many pools from 0.01 to any eth minimum. As basically all small miners join pool in BTC, we should compare BTC pools with ETH pools. |

For unknown reason, the "Total sent/received" amounts aren't showing.
I'm just sharing it here, the more block explorers out there, the better you can hide your private data from prying eyes.
Nice to see this new mempool.space. Are you maintaining it somehow? Maybe you could relabel it.? onionpool.space or something like that. I found some bugs, probably related to server stability A random address (with unconfirmed transactions, in the mempool) couldn't load at all ( http://loycevu3e75xlfrdxqueln6mk2dl2ditaqohpxgc35k2jezww6sxs4qd.onion/address/3FNdapWSNRovQcTR5i9YHxPh2a8rVC2kXV):  Other addresses look ok. |

Many would now consider it an unaffordable endeavour. But it clearly still works, providing the correct alignment of incentives is in place.
It does work, and now with the launch of Ethereum 2.0 with Proof of Stake we will see if is there any alternative that will really work. With the right PoW anyone can aswell be a verifier in the consensus mechanism without high barrier to entry problem. Verifiers could also earn some reward in a more advanced PoW when they achieve high degree of accuracy in a certain period of time. The reward does not necessarily have to be financial, it could be inform of good/positive Reputation, Merit etc This is not true. "Verifiers" do not receive merit neither reputation. The correct term is "miners", and they receive only bitcoin as a reward for their processing power and energy costs. This is not dependent of a "high degree of accuracy in a certain period of time", they just join a pool and receive rewards proportional to their processing power. |

Será mesmo que essa """porrada""" que a economia irá levar, é tão preocupante como dizem por ai?  A porrada já foi grande viu. Essa semana tivemos já o corte de fornecimento de gás russo para a Europa. Talvez isso seja o vale da crise e a partir de agora as autoridades se resolvam para terminar esse conflito insano que já dura desde fevereiro. Ninguém sabe qua será o fundo do poço, mas eu tenho fé que estamos saindo dele. |

Tenho uma duvida, será que a BUSD é uma stablecoin confiavel e transparente como a USDC, por exemplo!!?
Mas o que o @bitmover disse é algo totalmente coerente e tem nexo! A Binance irá "proteger o que é dela"...
Sim. A usdc é melhor na minha opinião pq a coinbase é mais transparente, por ser listada em bolsa. Mas a busd é duma parceria paxos e binance, e teoricamente é bem confiável. https://paxos.com/busd/Developed in Partnership with Binance
BUSD was created in partnership between the largest and most trusted companies in the crypto space.
Regulated
Paxos and BUSD are approved and regulated by the New York State Department of Financial Services, ensuring the utmost of consumer protections.
Backed by Dollars
BUSD is 100% backed by reserves held in either or both (i) fiat cash in dedicated omnibus accounts at insured U.S. banks1 and/or (ii) U.S. Treasury bills (including through repurchase agreements and/or money-market funds invested in U.S. Treasury bills).
Agora a minha duvida é, será que as demais corretoras vão seguir esse tipo de atitude que a Binance fez? Será que essa ""moda"" irá pegar?
Elas já fazem isso Não tem busd na coinbase. |

Binance were doing a promotion some time ago (it might still be active and probably is) for trading without fees.
Aside from that I don't think there's options without exchanges the recoup fees based on spreads.
Binance is the best option These are the trading zero fee pairs: https://www.binance.com/en/support/announcement/10435147c55d4a40b64fcbf43cb46329BTC/AUD, BTC/BIDR, BTC/BRL, BTC/BUSD, BTC/EUR, BTC/GBP, BTC/RUB, BTC/TRY, BTC/TUSD, BTC/UAH, BTC/USDC, BTC/USDP and BTC/USDT. Those are basically fiat and stable coins. |

Eles estão querendo dar um up na stable coin deles. É uma empresa e não tem pq ficarem ando apoio a concorrência né, como o usdc.
Isso é um grande incentivo para quem holda usdc converter isso em busd logo se pretende vender num curto prazo.
Algumas corretoras como a bitstamp por exemplo nem aceitam usdc em outra chain que não seja erc20. No meu caso já seria difícil vendereus usdc... teria q abrir conta numa terceira corretora.

You're not going to want to let crypto do things your government has provided that seems efficient (things like healthcare, education and handling waste).
Exactly . I will also add the police and military forces. The only "job" that crypto will really compete with government is the central bank. The capability to print money I don't think governments will stop printing money , neither that bitcoin will replace fiat. Governments will most likely use blockchain technology to do things on their own terms. |

Thanks for the response. Well i thought when there is any ledger update but especially firmware updates, it's best to wait few days first to see if there are issues with it mentioned by others first before you update?
I use ledger live software. I always keep it update as any other software. Just like n0nce said, it is safer and better to update as soon as it is released. There are no issues with balances now. And if you see any issue with balance, just delete the cache and it will work again. No reason to use an outdated software, and waiting a few days is useless. You will see another update again, as ledger launches a new version every few days. |

Although you can really heat your home with bitcoin mining, this is not the most efficient way to produce heat as its consume a lot more energy than a normal heater. And in particular "Bitcoin will not survive the coming winter". Both of these are wrong.
About this, it is not going to the winter all over the world at the same time. Bitcoin is not even mainly mined in Europe, and it is going to be mined anyway in other places while it is winter in Europe and Europeans are living their gas crisis with Russia. |

Binance quer entrar em peso no Brasil, contrataram Henrique Meirelles  Incrível mesmo. Certamente Meireles irá , além da posição de conselheiro, fazer relações públicas com o governo federal, representando os interesses da binance. Tipo um lobista Ele conhece todo mundo e é respeitado tanto num governo Lula quanto em um governo bolsonaro Deve tá ganhando muito dinheiro para aceitar essa posição. |

@Paredao, acredito que voce poderia sanar minha duvida, mas isso que voce disse, é com relação a epoca inflacionária que tivemos no Brasil, em que o Sarney era presidente certo?
Meados da decada de 80, inicio de 90, "Fiscais do Sarney", congelamento dos preços e etc...
Isso aí durou mais de uma década gagux123 Começou em 81 antes do Sarney. Teve aqueles planos cruzeiro, plano cruzado, plano bresser.. Continuou no Collor, que confiscou todo o dinheirocom liquidez no país.. pq ele achava que o problema era que o pessoal gastava muito A inflacao só foi controlada quando o FHC era ministro do Itamar e foi feit um plano para conter o gasto público (arrochos salariais, privatizações..) e o plano real, com paridade forcada com o dollar para ancorar os preços aqui nos lá de fora para ter concorrência |

Sabes em que data foi feito esse registo? Não consegui encontrar essa informação. Já está send possível sacar euros da binance, depois desse registro? Por enquanto estou usando a bitstamp pra saque em euros , mas eu ia preferir usar a binance q tem melhor volume |

Vi um vídeo muito bom do putin falando que a economia "imaginaria" estava sendo substituída pela economia real https://www.instagram.com/reel/CiDihdPoLI-/?igshid=YmMyMTA2M2Y=Ele fala que os países do mundo não aguentam mais a dependência do dólar, e que eles estão agora trocando dólar e euro por commodities, e que isso que está puxando a inflação no mundo. Bem Interessante. Não compartilho do ponto se vista dele totalmente mas existe alguma verdade aqui. |

Os EUA elevaram bastante as taxas de Juros recentemente, do contrário creio que estaria em uma situação muito pior.
Na verdade eu estou bastante surpreso com o Brasil ter controlado a situação tão rápido, creio que o fato dele ser um grande exportador de grãos e alimentos em geral tenha auxiliado bastante nisso.
O negócio não foi que controlamos a situação rápido. Demoramos pra controlar , e nem está 100% controlada ainda. Mas, a ibflacao começou antes da deles, e reagimos um ano antes. Estamos subindo os juros há quase 2 anos já. |
