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.

With the approval of altcoin ETFs, the ecosystem of the Crypto Assets market is quietly undergoing a transformation. Traditionally, the inflow of funds into Bitcoin and Ethereum often drives the alt zone, triggering what is known as "alt season." However, this time the situation is different.
The emergence of ETFs has changed the flow of funds. When traditional financial capital purchases ETFs, it no longer directly enters exchanges as before, thus reducing the possibility of flowing into small and medium altcoins. This change could have a profound impact on the entire Crypto Assets market.
In the future, if ETFs for well-known alts like Solana, Dogecoin, Litecoin, Cardano, Ripple, and Sui are approved, the new funds in the market are likely to be directly absorbed by these ETFs. This means that only a few alts that can enter the ETFs will have the opportunity to maintain their market position, gain trading volume, and attention.
For most altcoins that failed to enter the ETF, the loss of liquidity may lead them to gradually fade out of the market. This trend may result in future funds primarily concentrating on the main direction of "a few altcoins with ETF support + Bitcoin/Ethereum," while other projects may become marginalized in the market.
This change highlights the significant impact of ETFs on the structure of the crypto assets market. It not only alters the flow of funds but may also redefine the landscape of market participants. For investors and projects, understanding and adapting to this new trend will become crucial. At the same time, it also provides us with a new perspective to think about the future development direction of the crypto assets market.

As a Crypto Assets investor, I once walked a winding path of learning. When I first entered this field, I was dismissive of the simple Moving Average (MA) convergence divergence indicator (MACD) and instead obsessed with complex multi-indicator overlay strategies. However, this approach led to a loss of 800,000 yuan over three years. It wasn't until the moment I got liquidated that I realized: those fancy indicators were actually distractions, and the MACD that I had ignored was the key tool that truly contained the wisdom for survival.
After ten years of in-depth research, I have come to see MACD as a core strategy, evolving from my initial underestimation of it. I finally understand the essence of the crypto assets market: the so-called 'secret to getting rich' does not exist; true success comes from learning to use a reliable 'compass' to navigate steadily through the market's ups and downs after experiencing setbacks.
Why is MACD called the 'King of Indicators' in the crypto assets market? Here are five key findings that I have summarized through practical experience:
1. Time-tested risk management tool: The MACD, as an indicator used in global financial markets for decades, is undoubtedly reliable. When Bitcoin surged to $60,000 in 2021, despite the market generally optimistic about breaking through $100,000, the MACD showed a high-level divergence (price hitting a new high while the red bars shortened), which prompted me to reduce my position by 70% to avoid risk. Half a month later, the price of Bitcoin was cut in half, and I successfully preserved most of my principal.
2. A Powerful Tool for Trend Recognition: The core of MACD is the Exponential Moving Average (EMA), which can help investors grasp major trends. When the MACD's DIF and DEA lines are above the zero axis and the red bars are increasing, it usually indicates the beginning of an upward trend. For example, in 2020, I held Ethereum for six months based on this signal and witnessed its increase from $200 to $1800, a ninefold rise. Conversely, when the MACD is below the zero axis and the green bars are expanding, it often signifies the arrival of a downward trend.
3. Accurate Market Turning Point Warning System: MACD can also provide investors with potential bottom and top signals. This feature helps optimize entry and exit timing, improving investment returns.
Through a deep understanding and flexible application of the MACD, I have gradually mastered the key to surviving and profiting in the crypto assets market. This seemingly simple indicator actually contains rich market insights, becoming an important basis for my decision-making in this highly volatile market.
