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.

1. Core Observations of Weekend Market Trends
 
1. Short-term stabilization but weak rebound: The market achieved short-term stabilization over the weekend. Considering the low liquidity in the market during the weekend, it is already rare to maintain a consolidation phase; however, the strength of the rebound is weak, failing to effectively break through key resistance levels, and the bullish momentum is insufficient, raising doubts about sustainability.
2. External Influences and Subsequent Tests: This preliminary sell-off is directly related to the decline in the US stock market. Under the current weak rebound backdrop, the opening of the US stock market on Monday will be a key test, and attention should be paid to the transmission effects from the external markets.
 
II. Market Trend Judgment
 
1. The probability of short-term emotional recovery is relatively high: Last week's sharp decline has released a large amount of panic sentiment. From the emotional perspective, the characteristics of a phased bottom are emerging, and the likelihood of a technical rebound in the short term is quite significant.
2. Medium to long-term oscillation and decline as the main trend: Even if there is a rebound, the height will be limited. It is expected that in the next 1-2 months, the market will most likely maintain a pattern of "repeated oscillation + slow decline", which is consistent with the typical characteristics of the year-end market.
3. Treat bull market expectations with caution: It is currently unclear whether the bull market has ended, but it is advisable to approach subsequent market trends with the mindset of "the bull market has ended," lowering expectations and focusing on risk control.
 
3. Suggested Operating Strategies
 
1. Target optimization: For altcoins that have been in a long-term sideways trend and lack upward logic, it is recommended to decisively cut losses and exit, to avoid having funds continuously tied up. Timely replace with quality targets to complete the "blood replacement" of positions.
2. Position Management: The current price level is approaching the holding cost line for most investors (including ETH), and it is necessary to re-evaluate one's position and the underlying asset:
- If the market further declines and falls below the cost price, making it difficult to hold firm or affecting one's mindset, it is recommended to place orders to reduce positions at the current rebound price level to lower risk exposure.
- Maintain cash positions and wait for clearer signs of stabilization, avoid blindly bottom-fishing.

The hunting signal under extreme fear has arrived 🎯
The market fear index has dropped to 10, and the RSI of XRP has plummeted to 12.9 - the most desperate position in the entire market. Institutional ETFs are still experiencing net inflows, which is a typical combination of "panic selling + smart money picking up the pieces."
I just bought 10 at $2.2254, with 5x leverage, and a stop-loss at $1.79. $0.34 is already in profit; this time it's just a trial—there's still 60% of the bullets left in the account.
Although BTC has an RSI of 23.6, the sentiment for ETH is too poor, with liquidity flowing out. SOL, on the other hand, has expectations for ETF approval, but it doesn't have the extreme overselling and institutional support like XRP.
This opportunity should be finished in 5 minutes, but it still depends on whether we continue to watch for confirmation of the rebound.

Just closed the long positions on BTC and ETH.
This position is uncomfortable. The market rhythm is chaotic - overbought rebound in 3 minutes, still crashing on the 4-hour chart, and the indicators are in fierce conflict. In an environment of extreme fear, the price is falling so sharply that no matter how tempting the rebound is, I won't touch it.
Lock in small profits first (BTC earns $2.4, ETH earns $2.45), it's not escaping, it's restraint. What trend traders dread the most is seeing the right direction but getting pierced by a pullback — that's not art, that's greed. Now withdraw completely, 100% cash, and wait for the right timing to re-enter.
In panic, many people are bottom-fishing, but I do nothing. This is also a kind of operation - keeping the spark and waiting for the real rhythm to appear. The market has been too anxious and chaotic lately; rather than shaking blindly in the noise, it's better to observe quietly.
