Porquê comprar Ethereum(ETH)?

O que é a Ethereum? A plataforma para contratos inteligentes e aplicações descentralizadas
A Ethereum (ETH), fundada por Vitalik Buterin em 2015, é a primeira blockchain pública do mundo que suporta contratos inteligentes. A Ethereum permite que os programadores criem aplicações descentralizadas (dApps), protocolos DeFi, NFT e muito mais, impulsionando um crescimento explosivo no ecossistema Web3. O Ether (ETH) é o token nativo da rede Ethereum.
Como é que a Ethereum funciona? EVM, taxas de gas e consenso
A Ethereum baseia-se em nodos distribuídos, sendo que cada transação exige ETH como "taxa de gas". Os contratos inteligentes executam automaticamente acordos condicionais, amplamente utilizados em finanças, jogos, cadeias de abastecimento e muito mais. Inicialmente a utilizar PoW, a Ethereum completou a atualização "The Merge" em 2022, fazendo a transição total para Proof of Stake (PoS), reduzindo o consumo de energia em mais de 99% e melhorando a sustentabilidade e a segurança.
Mecanismo de oferta e PEI-1559
A Ethereum não tem um limite de fornecimento fixo, mas desde o EIP-1559, uma parte do ETH é queimada com cada transação, ajudando a reduzir a pressão inflacionária. O ETH é essencial para o pagamento de taxas de gas, recompensas de staking e participação na governação, com a procura a crescer a par da expansão do ecossistema.
Ecossistema e casos de utilização
Os padrões ERC-20 e ERC-721 da Ethereum alimentaram o surgimento de DeFi e NFT, dando origem a projetos como Uniswap, Aave e OpenSea. A Máquina Virtual Ethereum (EVM) fornece um ambiente de programação flexível, promovendo a interoperabilidade entre cadeias e soluções de escalonamento da camada 2 (por exemplo, Rollups, Sharding).
Razões e riscos para investir na Ethereum
Infraestrutura Web3 e de contratos inteligentes: o ETH é o principal ativo para DeFi, NFT, DAO e outras aplicações inovadoras. Atualizações técnicas e crescimento do ecossistema: a transição PoS e o EIP-1559 melhoram o desempenho da rede e a captura de valor. Elevada liquidez e aceitação do mainstream: o ETH é negociado a nível mundial, ficando apenas atrás da Bitcoin em termos de capitalização de mercado. Riscos: congestionamento da rede, taxas de gas elevadas, concorrência de blockchains emergentes (por exemplo, Solana, Avalanche) e incerteza regulamentar.
Pontos de vista céticos e perspetivas alternativas
Embora o ecossistema da Ethereum seja vasto, persistem problemas de escalabilidade e de taxas. Se não os resolver, poderá ser ultrapassada por blockchains mais recentes e de elevado desempenho. Os investidores devem acompanhar o progresso tecnológico e as mudanças no ecossistema.

#数字资产市场动态 $SOL has surged to a four-hour high again in recent days, now repeatedly testing around the moving averages. Both bulls and bears are exerting effort, making this market quite interesting. From the candlestick chart, SOL continues the previous suppressed pattern—volume was decent when it just broke through, but once it moved higher, it started to lose momentum, with trading volume clearly shrinking. The MACD fast and slow lines are still oscillating below the zero line, showing signs of turning upward, but the resistance at the 125 level must be taken seriously. Whether it can break above this level effectively will be crucial for the subsequent trend.
The hourly chart also reveals some clues—after the Bollinger Bands widened, they quickly contracted again, which essentially indicates that trading volume is not keeping pace. This rapid rise followed by slowdown is most likely to create technical divergence, so paying close attention to whether volume can support the move is key; this is the decisive factor.
Simple trading strategy: 125-128 is a short-term resistance zone. If broken, look toward 130. If it pulls back, maintain support at 118-115. But don’t just focus on $SOL; $BTC and $ETH should be monitored simultaneously, as Bitcoin remains the engine of the market, and the direction of major coins is often determined by BTC. When volume and price move in harmony, the market has more credibility.

#美国宏观经济指标链上化 280 Billion USD Options Single-Day Settlement Comes to an End, The True Story Behind Is Just Beginning to Surface
Just experienced a rare-scale options settlement—$280 billion in positions settled within a single day. This is not just a numerical event; it’s a thorough clearing of both bullish and bearish sides in the market.
The outcome of the settlement is quite interesting. BTC’s maximum pain point is set at $95,000, and ETH at $3,100. But now? Both prices have been broken through. A large number of call options have become worthless, and the short-term selling pressure has been completely released. It appears to be a victory for the bears.
But if you only look at the surface, you’ll miss the real signal.
What happened after the settlement? Big funds started quietly adjusting their positions—large positions shifted towards quarterly options for March next year, and the vast majority of these are out-of-the-money call options. To put it plainly: these institutions are betting with real money that there will be a significant rally in Q1 next year. They are already laying out plans for the next stage of the story.
A few truths for retail investors:
Don’t be fooled by the current bearish sentiment. The weak market in Q4 is no secret, but it also indicates that the negative factors have been fully priced in. Institutional money has already started moving; why are you still anxious?
Options are really not suitable for ordinary people’s hands. They are tools used by institutions for hedging. But understanding the logic behind them is most important—smart money is preparing for a mid-term rebound.
On the operational level, spot positions can start being accumulated gradually, especially when prices hit key support levels. A bull market is like this: sharp declines are just interludes in the journey, and the story always blooms in despair.
Remember this logic: settlement data speaks, and changes in institutional positions also speak. Learning to read these signals is more valuable than chasing market hype.

#数字资产市场动态  Today marked a historic milestone in crypto options expiration—the largest one to date, with a total of approximately $27 billion to $28.5 billion being closed out (with $BTC accounting for about $23.6 billion to $23.8 billion, and Ethereum around $3.8 billion). Will the market be turned upside down?
Actually, it has little impact on the overall trend. Events like this are usually reflected in the market a few days in advance. The recent three days of continuous decline, and today’s rebound, are just false signals. It’s common to see 2 to 3 fake breakouts in a row.
The stop-loss levels set by short sellers are clearly visible to the big players. If they don’t first take out these stop-loss orders, how can they push the market up? When a genuine upward trend appears, capital will start to accumulate. During this phase, the market’s pullback is small, and its resilience is strong, creating a chance for a slow upward breakout. Bitcoin needs to withstand pressure in the 89-90 range; these levels are critical.
