Por que comprar Ethereum(ETH)?

O que é Ethereum? A plataforma para contratos inteligentes e aplicativos descentralizados
O Ethereum (ETH), fundado por Vitalik Buterin em 2015, é a primeira blockchain pública do mundo que suporta contratos inteligentes. O Ethereum permite que os desenvolvedores criem aplicativos descentralizados (DApps), protocolos DeFi, NFTs e muito mais, impulsionando um crescimento explosivo no ecossistema Web3. Ether (ETH) é o token nativo da rede Ethereum.
Como funciona o Ethereum? EVM, taxas de gas e consenso
O Ethereum depende de nós distribuídos, com cada transação exigindo ETH como uma “taxa de gas”. Os contratos inteligentes executam automaticamente acordos condicionais, amplamente usados em finanças, jogos, cadeias de suprimentos e muito mais. Inicialmente usando o PoW, o Ethereum concluiu a atualização “The Merge” em 2022, fazendo a transição completa para o Proof of Stake (PoS), reduzindo o consumo de energia em mais de 99% e aumentando a sustentabilidade e a segurança.
Mecanismo de abastecimento e EIP-1559
O Ethereum não tem limite de oferta fixo, mas desde o EIP-1559, uma parte da ETH é queimada em cada transação, ajudando a reduzir a pressão inflacionária. A ETH é essencial para pagar taxas de gas, recompensas de staking e participação na governança, com a demanda crescendo junto com a expansão do ecossistema.
Ecossistema e casos de uso
Os padrões ERC-20 e ERC-721 do Ethereum impulsionaram o surgimento de DeFi e NFTs, dando origem a projetos como Uniswap, Aave e OpenSea. A Ethereum Virtual Machine (EVM) fornece um ambiente de programação flexível, promovendo a interoperabilidade entre cadeias e soluções de escalonamento de camada 2 (por exemplo, Rollups, Sharding).
Razões e riscos para investir no Ethereum
Web3 e infraestrutura de contrato inteligente: ETH é o principal ativo para DeFi, NFT, DAO e outros aplicativos inovadores. Atualizações técnicas e crescimento do ecossistema: a transição PoS e o EIP-1559 aprimoram o desempenho da rede e a captura de valor. Alta liquidez e aceitação geral: a ETH é negociada globalmente, perdendo apenas para o Bitcoin em capitalização de mercado. Riscos: congestionamento da rede, altas taxas de gas, concorrência de blockchains emergentes (por exemplo, Solana, Avalanche) e incerteza regulatória.
Visões céticas e perspectivas alternativas
Embora o ecossistema do Ethereum seja vasto, os problemas de escalabilidade e taxas persistem. A falha em resolvê-los pode fazer com que sejam superados por blockchains mais novos e de alto desempenho. Os investidores devem monitorar o progresso tecnológico e as mudanças no ecossistema.

Shiba Inu (SHIB) is a decentralized cryptocurrency (altcoin) based on Ethereum launched in August 2020 by an anonymous creator named Ryoshi. Known as a "meme coin" and often called the "Dogecoin Killer," SHIB has evolved from an internet joke into a serious ecosystem, including tokens BONE and LEASH, as well as its own blockchain, Shibarium.  
Here are the key points about Shiba Inu:  
Origin: Inspired by the Japanese dog breed, Shiba Inu, which also serves as the mascot for Dogecoin.  
Purpose: Created as an experiment in building a decentralized community (often called SHIB Army) to rival Dogecoin's dominance.  
Ecosystem: SHIB is not just a coin but has a decentralized exchange platform (ShibaSwap) and a Layer-2 blockchain (Shibarium) to improve transaction efficiency.  
How It Works: Based on Ethereum (ERC-20 token), allowing it to interact with other decentralized finance (DeFi) applications.  
Value: It was once a phenomenon due to its very high price increase, but its price is highly volatile and influenced by meme coin market trends.

The courts have now opened for the $71 million worth of ETH frozen following the Kelp DAO hack. Aave has filed an urgent application with a New York federal court demanding the return of these funds to their users.
The events unfolded as follows: Following the April 18th $292 million rsETH exploit, the Arbitrum Security Council successfully froze 30,766 ETH linked to the attacker. Just as the funds were about to be returned to the victims, the US law firm Gerstein Harrow LLP intervened. Citing a total of $877 million in terrorism damages awarded against North Korea in 2010, 2015, and 2016, the firm obtained a restraining order on May 1st. Their reasoning was that the attack was allegedly linked to the Lazarus Group, therefore the frozen assets should be considered North Korean property.
Aave's lawyers have taken a firm stance against this claim.  The application states, "A thief doesn't become the legal owner of stolen goods simply because he held them for a few hours," emphasizing that the North Korea claim is based on internet rumors and lacks concrete evidence. Aave also warns that if this restriction continues, protocol users may be unable to meet their collateral obligations, and the risk of chain liquidation could threaten the entire DeFi ecosystem. They are requesting the court to immediately lift the restriction, or if that's not possible, that the plaintiffs deposit $300 million in collateral. An emergency hearing will be held tomorrow.
This case is a first for DeFi. For the first time, the question of who owns the recovered hacked funds is being addressed in a courtroom. Whatever the answer, it will set a precedent that will determine the fate of all future recovery operations.
Justice is served not when those who pursue good find justice, but when those who pursue good find justice.

Insiden Kelp DAO Picu Arus Unstaking 433.158 ETH on Ethereum DeFi Protocol
Panic has swept the restaking ecosystem following a protocol hack of the Kelp DAO bridge worth $292 million by a hacking group suspected to be linked to Lazarus. As a result, the Ethereum validator withdrawal queue surged sharply to 433.158 ETH on Sunday (5/3). This phenomenon accelerated the outflow of funds from rsETH assets and caused the total value locked (TVL) across various DeFi protocols to plummet by up to 30% over the past 12 weeks.
This withdrawal queue spike is extremely drastic, recorded to have increased by up to 72,000% in just the last two weeks, with withdrawal wait times now swelling to seven days. On-chain analysts say that asset holders are beginning to assess that the risk of losing capital due to hacking is far greater than the returns offered by current restaking protocols.
Despite the massive unstaking flow, the Ethereum network still shows resilience. The queue for new staking remains at 3.6 million ETH, or about seven times the size of the withdrawal queue. Currently, 31.7% of the total Ether supply remains locked within the network, which is expected to serve as a buffer against selling pressure to prevent the price from falling below the critical support level of $2,241.
