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 oferta 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.

February 2 Cryptocurrency Market Analysis & Strategy
• BTC 🪙: Current price approximately 76,900 USD, in a low-volatility consolidation phase after a deep pullback. 76,500 is the key support level today; holding above it offers a rebound opportunity, while breaking below suggests further weakness.
• ETH ⚡️ (Two Coins): Current price approximately 2,280 USD, moving in tandem with BTC's weak consolidation. 2,260 is the short-term support level, and 2,330 is the resistance level. Currently adopting a sideways trading approach.
🎯 Bitcoin Strategy: Buy in batches at 76,500-77,000, targeting 78,000-78,500, with a stop loss at 76,200 (if it effectively breaks below 76,500, switch to short).
🎯 Two Coins Strategy: Light long positions at 2,260-2,290, targeting 2,330-2,360, with a stop loss at 2,240 (if it breaks below 2,260, switch to short).

2-2 Morning Ethereum Analysis
From the daily chart perspective, recent market movements have shown a large bearish candle accompanied by a long upper shadow, indicating a weak pattern that has directly triggered a waterfall-like breakdown. The price has consecutively lost three key support levels at 2600, 2400, and 2300 without resistance, only stabilizing temporarily around 2240. The intensity of the bearish selling pressure is evident, and market panic sentiment has increased.
 
Looking at the moving average system, a complete bearish alignment has formed, with the price continuously under pressure from all short-term moving averages. Each minor rebound is ruthlessly suppressed by the moving averages, and the bulls have no strength to fight back, failing to generate effective upward momentum. The market is clearly dominated by the bears.
 
Based on current market sentiment and technical signals, Lao Guo provides specific trading ideas for the second pattern:
In the short term, the market is likely to experience a technical rebound correction, with a short position in the 2320-2350 range, targeting 2200-250. If the support at 2100 is broken, further decline is expected to 2100#GateLive直播挖矿公测开启

【February 2 Market ICU · Nine Critical Alerts】
Chief Physician: Eudora Qi
【Nine Critical Indicators】
Cardiogenic Shock: BTC price continues to hit new lows, approaching the annual bottom.
Hematopoietic Failure: Blizzard impacts US mines, Bitcoin hash rate experiences a “natural halving.”
Vascular Embolism Warning: The upper threshold of 80,000 and the lower threshold of 1,830 form two “billion-level liquidation lines,” breaching which could trigger a stampede embolism.
Immun Storm: Meme coin BULLA’s market cap evaporates by 90% overnight, speculative cells undergo acute necrosis.
External Infection: Cross-chain bridge is attacked again by hackers, open wounds continue to bleed.
Deteriorating Environment: 12 EU countries tighten crypto tax rules.
Long-term Rejection: FTX creditor payouts will be released by March 31, posing potential selling pressure.
Drug Shock: Key non-farm payroll data is about to be announced, which will disrupt the overall market.
【Pathological Diagnosis and Causality Chain】
Primary Lesion: Physical world forces (blizzard) cause “hematopoietic function” (hash rate) to undergo acute failure, a unique structural blow that weakens the network from the bottom up and prolongs risk cycles.
Core Manifestations: Triggering cardiogenic shock (new price lows) and hypercoagulability (liquidity depletion).
Fatal Complications: The risk of embolism at the billion-level liquidation line sharply increases, accompanied by systemic immune storm (Meme zeroing).
Worsening Environment: External infections, tightening regulations, and long-term rejection risks stack up.
Conclusion: This is a complex critical condition caused by structural physical blows that have triggered systemic financial stampede risks. Rescue goals: prevent embolism, counter shock, control infection.
【Level 3 Emergency Plan】
Level 1: Mandatory risk avoidance for all (responding to shock and embolism) Iron law: All bottom-fishing is strictly prohibited before prices clearly stop falling, stay away from liquidation lines, and panic selling significantly decreases.
Highest Command: Reduce risk exposure at all costs (reduce positions, deleverage, convert to cash). Cash is the safety belt.
Level 2: Critical Care (Monitoring Lifelines) Keep an eye on: Set the absolute operational boundaries at BTC 80,000 and ETH $1,830. Offline, only execute Level 1 plan.
Monitor Bleeding Points: Continuously observe the recovery of the entire network hash rate to assess the extent of structural damage.
Level 3: Infection Prevention and Control (Managing External Risks) Avoid infection sources: Be extremely cautious of complex DeFi applications, new assets, and high-yield mining.
Manage Rejection Calendar: Mark March 31 (FTX payout) and the non-farm payroll night in red, and exercise extra caution then.
Summary: Full risk avoidance, monitor liquidation, observe hash rate, prevent infection. During multi-organ failure, the goal is to “support” and “wait” for the body to heal itself, not to attack.
【Rescue Verification and Action Instructions】
Core Diagnostic Quick Questions:
Q: Which is a unique, structurally caused condition directly triggered by physical world forces?
A. BTC price approaching new lows
B. Blizzard impacts mines causing “natural halving” of hash rate
C. Meme coin zeroing overnight
