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.

Family, that breath I held a few days ago was truly worth the wait. 📉🔥👀 In the morning, when I opened the charts, $FET  directly broke that high-level stubbornness from a few days ago. FET had already shown signs of weakness before I went to sleep a few days ago, and at that time I felt that shorting was the smoother move.
What I saw before sleeping a few days ago was: lackluster rebounds, clear resistance, and each upward push falling just short.
At this level, I didn't want to chase longs. Going short was just a convenient confirmation; what's truly more comfortable is waiting for it to loosen up on its own.
When you're making money, the scariest thing is suddenly losing your cool.
Some money isn't earned on impulse.
Take profits when you should. ✅
So I opened a short around 0.2643, which went all the way to 0.1791, +2287.32%. This wave was cashed out quite cleanly 📈🎉. First close 80%, the remaining 20% protected at cost; if it continues to drop, let the profits run.
If you missed it, don't chase. Don't get hung up on the last leg ⚠️. Wait for the next clearer signal. The market doesn't lack opportunities 🔔

🤯Breaking news! In the time it takes to take a shower, Bitcoin just shot straight to $60k🚀! Big Brother Maji couldn't hold back either! Wait, Trump says they've reached a deal, but Iran says nothing of the sort?
Woke up completely stunned in the middle of the night😖!
Trump loudly announced on social media: US-Iran talks "will be held in Doha tomorrow," and Iran has requested the talks. As soon as the words were out, the US stock market surged by $760 billion in market cap.

But then Iran's Deputy Foreign Minister poured cold water: Reports of technical talks between Iran and the US in Doha this week are not true. The Iranian embassy in Doha also added: Preparations for talks have not yet begun.

One says talks are happening, the other says not—who's lying?
Regardless of the truth, the market rallied first. $BTC  broke through $60k directly, and ETH also surpassed $1,600.
📊:
$BTC  ‌Now at $60,414, 1-hour RSI hit 71.78, a bit hot in the short term. But the daily MACD just formed a golden cross, with a bullish trend forming.
$ETH  ‌This surge is even stronger, straight to $1,620, with a 1-hour RSI of 75. However, note that around $1,630 is a previous high resistance level, and there's significant selling pressure here.
Interestingly, Big Brother Maji decisively added 800 ETH during this breakout, currently with an unrealized profit of about $64k, pretty sweet😍. But his average cost is $1,590, liquidation price $1,589—this position is just $30 away from the liquidation line, quite a gamble.
💡 Let's talk facts:
Whether the US and Iran will actually talk or not, no one knows for sure. Trump says they will, Iran says they won't—each side telling its own story. In such extreme information chaos, chasing highs requires extra caution.
The $60,000 level has historically never been an easy hold.

Say no more, this really woke people up! 🔥📉  
Last look before bed, $HFT  was still hovering around the highs, unable to push up or make a clean drop. Many people can easily get itchy hands from this kind of consolidation.  
While the price was grinding the top during the session, I was watching HFT and noticed that every time it tried to push up, it lacked momentum 👀 The buying pressure wasn't strong, support was insufficient, and it would fall back as soon as it hit the resistance level. This isn't strength, it's weakness. So I advised following the bearish rhythm and opened a short position around 0.01033.  
Now the price has come to 0.00862, with a return rate of +405.92% 🎉✅ This wave wasn't in vain; the short position was realized cleanly.  
If you understand, execute. Don't hesitate at the last moment.  
Good positions are waited for, not chased.  
On my end, I'm closing 80% of the position 💰 and protecting the remaining 20% at cost price. If it continues to fall, let the profits run. If it bounces back, don't be greedy for the last bite ⚠️  
If you missed it, don't chase 🚨 Chasing from behind is easy to get hit. Wait for the next clear signal, and move when a new position appears 🔔
