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.

Bitcoin plunges! Why is it down—can you buy the dip? Let’s talk about current trading opportunities.
1. First, let’s talk about why it’s falling! This is causing quite a stir. The culprit behind the crash is a semiconductor breakdown: Samsung and Hynix both slid further, with Hynix down another 16%. I even heard there were locals jumping to their deaths. Meanwhile, A-shares and U.S. pre-market both followed suit and dropped together, so Bitcoin got dragged down by the broader environment. Then the question is: why is Hynix down?
2. The logic behind Hynix’s drop is very simple: good news is already exhausted. Hynix listed in the U.S. on Friday, and there was a short-term surge; we were also going long on Micron at that time, moving from over 900 to 1000. After the good news is exhausted, it becomes bearish and the price starts to retrace—this usually lasts for a few days. I’m looking to see if there’s a better entry opportunity.
3. Compared to that, Bitcoin is down only 1.5%—you could say it hasn’t really dropped much. This is a strong signal. Its support is around 62,600 and 61.5k. Yesterday, @舒琴 posted that it’s a good time to set up a layout for a rebound—I saw many of you put in orders at 62,600. Congrats, you caught that support rebound~
4. Then Ethereum’s resistance around 1,830 is also doing its job. After touching it again, it plunged hard. This resistance level was also mentioned by @舒琴 more than twice—so congrats to the ones who acted on it. As for buying the dip, because of uncertainty in the U.S. stocks, I lean more conservative: I prefer going long near the stronger support around 1,730, which corresponds to BTC around 616k. Let’s see whether the market gives us the chance.
5. Actually, even if we don’t get the chance, it’s fine. Our main position already took the full profit. We held ETH at 1,530 and sold at 1,830—that’s already enough. In the consolidation period now, we just do some small swings. It’s better than nothing. And for Micron MU, we bought a dip at 900 and let everyone take profit at 1000—because Hynix’s good news is exhausted. As shown in the chart, @舒琴 also flipped and shorted once around 1000. I’m currently considering taking profit on pullbacks.
6. I think these logics are very clear. Earn money in the way that matches your own understanding. If you don’t know this, you definitely can’t make money. Just follow me and trade aggressively every day #PreIPOs第二期OpenAI认购 $BTC $ETH

7/13 evening:
Judging by the technical structure of BTC, it is still in a buildup-and-consolidation stage at the larger level. On the 4-hour chart, the MACD lines are sticking near the zero axis, the green histogram bars are shortening, indicating that bearish momentum is fading, but the bulls have not kicked in yet. This kind of tug-of-war of “about to break but doesn’t,” is most prone to chasing pumps and killing trades!
Trading advice:
BTC: Go long from 62,000-62,500, target 63,500-64,500
ETH: Go long from 1,750-1,765, target 1,800-1,850#伊朗宣布关闭霍尔木兹海峡 $BTC  ‌$ETH  ‌

Don’t say—this round really gives face! Waffling before bed, and when you wake up you’re already full of energy 🚀🎉
A few days ago, after $DEXE pulled back at night, it kept holding steady. Before the market had fully started, what I saw was that the buy-side strengthened and the support below was clearly there. Back then, I prompted going long around 16.684—not because I was impulsive, but because the structure presented an opportunity.
 
No fear if it moves slow—only fear if you mess up.
Take profit when it’s time.
 
Now it’s already at 43.516, +3163.29% sitting right here 📈💰🔥 This piece of meat feels great—patiently wait at the front, then take it decisively afterward. If you nail the rhythm, the chart will naturally give you feedback.
 
The handling is simple ✅📌 First take profit on 80%, and use the remaining 20% to protect the cost basis. If it continues pushing up, let the profits run. Even if it dips, don’t turn gains into a “key level.” Don’t get sentimental with profit.
 
If you missed it, don’t chase ⚠️ Chasing and rear-ending easily throws your mindset off. Wait for a pullback confirmation, wait for the next clear signal before looking again. There will be more opportunities ahead—just be patient and wait for the next shot 🔔
