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.

The market took a real beating today—pretty rough across the board. Bitcoin and Ethereum both felt the pressure, and equities weren't spared either. It's the kind of day that tests patience. Hopefully we'll see a turnaround soon. A strong bounce in BTC and ETH would certainly help restore some confidence, especially with traditional markets like SPX also weighing on sentiment. Days like these remind us why position management and risk awareness matter so much in trading.

## Which cryptocurrencies show the greatest potential in 2025?
The digital asset market is constantly evolving with new projects, but not all of them have real value. Some are used in fraudulent schemes, but there are serious solutions that truly drive the industry forward. It is important to understand which cryptocurrency is the most promising for the upcoming year based on fundamental indicators and market trends.
## Smart contract platforms: the foundation of the ecosystem
**Ethereum (ETH)** continues to be the king among smart contract platforms. Today, its value is $2.93K with a market capitalization of $354.18B. The Ethereum ecosystem stands out with the highest developer concentration, the largest total value locked (TVL), and regulatory approval in the USA. This allows the platform to maintain its leadership position in decentralized applications.
**Solana (SOL)** competes with Ethereum due to its architectural advantage: the network can process over 50,000 transactions per second with minimal fees. Currently, SOL is trading at $126.64 with a capitalization of $71.18B, ranking fourth. The rising popularity of memecoins and the development of DeFi services attract new waves of users. However, it is worth considering that a focus on memecoins could become a vulnerability—declining interest in this asset class may lead to reduced network activity.
**Avalanche (AVAX)** positions itself as a next-generation platform for smart contracts and decentralized applications. Its unique consensus mechanism provides nearly instant transaction confirmation. At present, AVAX is valued at $12.25 with a market cap of $5.26B. A key feature of Avalanche is active support for tokenization of real assets (RWA), a trending area gaining momentum in the market.
## Infrastructure and blockchain interoperability
**Chainlink (LINK)** remains a key solution for decentralized oracle services. The token is used within the Chainlink network to ensure reliable data transfer from external sources. The current LINK price is $12.78, with a market cap of $8.91B. In 2024, Chainlink’s role in the RWA segment significantly increased, confirming the project’s long-term potential.
**Polkadot (POL)** addresses the issue of blockchain fragmentation by creating bridges between different networks. The platform enables heterogeneous blockchains to exchange data efficiently and coordinate actions. The price of POL is $0.11 with a market capitalization of $1.18B. Its main advantages are true interoperability support and high flexibility in architecture.
## Decentralized exchanges and payment solutions
**Uniswap (UNI)** — the leading decentralized exchange within the Ethereum ecosystem and the largest in the industry. The UNI token is used for protocol governance and voting on its changes. Since the beginning of 2024, trading volumes on DEXs have doubled, and the trend is expected to continue. Increasing regulation of traditional markets is pushing users towards decentralized platforms where trust in third-party assets is unnecessary. The current UNI price is $5.02, with a market cap of $3.16B.
**Toncoin (TON)** stands out with its integration with Telegram, one of the largest messengers in the world with nearly a billion users. Since spring 2024, the value of TON has increased by 300%. Recently, the Tonhub crypto wallet launched a Visa debit card in EU countries, allowing transactions in TON and USDT. Expansion to other regions is planned for 2025. The potential to attract a mass audience makes this project one of the most interesting.
## The next generation of scalable networks
**Near Protocol (NEAR)** positions itself as a scalable blockchain with minimal fees and high throughput. The project competes with Ethereum and Solana as infrastructure for decentralized applications. The team is actively working on integrating artificial intelligence and blockchain abstraction. The current NEAR price is $1.53 with a market cap of $1.96B.
**Sui (SUI)** — a new-generation blockchain developed by engineers with experience from Meta. Recent updates increased transaction processing speed by 80%, leading to a rise in the platform’s price and popularity. SUI is valued at $1.47 with a market capitalization of $5.49B. The platform attracts investments due to its focus on DeFi development and decentralized applications.
## Protocol governance
**Injective** provides management rights and decision-making participation to holders of the same-named token. The protocol was launched in January 2021 and continues to evolve as a specialized platform for derivatives trading.
## Conclusions
All the projects listed above are among the most capitalized assets in the market, confirming the dominance of smart contract platforms, growing interest in decentralized finance, and the integration of artificial intelligence. However, investing in cryptocurrencies requires thorough analysis, as the market remains volatile and full of uncertainties.

ETH is still below the daily trend line. It is not recommended to short before it breaks below; continue to watch for a rebound. The fear index is only 11, which is very low. This position aligns with the previous plan for dollar-cost averaging, so you can continue to position yourself.
The non-farm payroll data will be released at 9:30 PM. It is expected to cause some spikes up and down. It is recommended to place long positions at 2934 and 2891 respectively, to see if you can catch a pullback. Remember to set the stop loss at 2860, as this risk-reward ratio is relatively reasonable. If you have an aggressive approach, small long positions can also be tried within this range, but risk control is essential.
