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.

$ZKJ  Honestly, I don't know. Before this fan, I took in 1000 USDT and added me.  
He said he wanted me to guide him, claiming he lost 20,000 USDT and was preparing for one last dance.  
At that time, I saw he had lost so much and thought I’d help him recover a bit.  
Last month, the market was especially good, and I made back 40,000 USDT in just one month.  
Plus, the rave coin suddenly appeared out of nowhere!  
I notified him and my other fans two days in advance to set up an ambush.  
I remember we entered the market at around 0.98.  
This round, I took profit of 60,000 USDT.  
Later, this fan said he needed to adjust and wouldn’t trade for now.  
I can't force him if he doesn't want to trade.  
If he doesn't want to trade, then just don't trade.  
I don't have that kind of coercion. 😄  
A few days ago, he came back and said he lost again.  
I told him to increase his position a bit.  
But he went ahead and opened a position on his own.  
Today, I asked other fans to do more ZKJ.  
Today, it’s about to be delisted, and I expect another dip today.  
When that happens, I’ll let him come out then!!! #加密市场小幅下跌 $ETH

Recently, I spent some time reviewing the major decentralized exchanges (DEXs) in the current market and found that this sector is changing very rapidly. Honestly, the development of decentralized exchanges over the past two years has far exceeded my initial expectations. From simple swap tools at the beginning, it has now evolved into a fully functional DeFi ecosystem.
First, let’s talk about why it's important to pay attention to decentralized exchanges. Compared to centralized exchanges, the biggest advantage of DEXs is that you have complete control over your assets, eliminating the risk of holding coins on an exchange. Additionally, trading fees are usually lower, and liquidity is continuously improving. Of course, security still depends on your own judgment; choosing audited projects is very important.
If you want to pick a leading decentralized exchange, Uniswap is almost unavoidable. The liquidity scale of this project is truly impressive, with TVL consistently ranking at the top of the industry. Its automated market maker model has become the standard configuration for DEXs, and it supports a wide range of blockchain ecosystems, from Ethereum to Polygon, Arbitrum, and Optimism. The fee structure is also flexible, with tiers at 0.05%, 0.3%, and 1%, allowing users to choose based on their needs.
In derivatives trading, dYdX is considered to be quite advanced. It allows users to trade over 35 types of perpetual contracts for cryptocurrencies, and there are no gas fees, which significantly reduces costs for frequent traders. Founded by former Coinbase engineer Antonio Juliano, this project indeed has some unique ideas in product design.
Decentralized exchanges on different chains each have their own features. PancakeSwap on BSC attracts many users due to low costs and fast transactions. In the Solana ecosystem, Raydium and Jupiter also hold their own positions. Raydium’s liquidity is quite stable, often exceeding $950 million, while Jupiter acts as an aggregator providing better prices. The Osmosis project in the Cosmos ecosystem connects over 50 blockchains via the IBC cross-chain protocol, showcasing impressive cross-chain capabilities.
Regarding stablecoin trading, Curve Finance is a top-tier player. Its 0.04% trading fee is among the lowest in the market, and its TVL exceeds $2 billion. It also undergoes thorough security audits. For swapping between stablecoins or hedging, Curve is a very good choice.
There are also some emerging decentralized exchanges worth paying attention to. For example, Aerodrome on the Base chain charges only 0.2% fees, and its user experience is continuously being optimized. Balancer offers more flexibility with its customizable liquidity pools, allowing users to create pools with up to 8 different tokens.
When choosing a decentralized exchange, I think the most important indicators are: liquidity size, which determines how quickly you can execute trades; user interface friendliness, which affects the trading experience; the completeness of security audits, which relates to fund safety; the number of supported tokens, which affects your options; and trading fees, which directly impact your returns.
Overall, the ecosystem of decentralized exchanges is now quite mature, with different projects focusing on various aspects. Whether you want to do simple token swaps, provide liquidity to earn fees, or trade derivatives, there are decentralized exchanges available to meet your needs. The key is to select a platform that matches your trading habits and risk tolerance, while also ensuring proper security measures.
