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.

Coinbase makes a major prediction for the 2026 crypto market! Stablecoins will reach 1.2 trillion, AI + crypto become new growth drivers
The first authoritative guide for the new year in the crypto space is here! Global crypto trading giant Coinbase released its 2026 Bitcoin and cryptocurrency market outlook report on December 31, 2025, providing a comprehensive set of predictions covering regulatory trends, technological innovations, and market directions. The report contains many key signals: major changes in US regulation are expected, institutional funds will accelerate their entry, AI and crypto will deeply integrate, and it is even predicted that by 2028, the total market cap of stablecoins will surge to $1.2 trillion, disrupting the payments industry. This is not just a market outlook but also a “roadmap” for the crypto industry in 2026. Understanding these trends is essential to catch the next wave of opportunities!
💰Two Major Bills Pave the Way💰
Coinbase emphasizes in the report that one of the core variables for the crypto market in 2026 is the implementation of regulation. As artificial intelligence drives the US economy toward cautious optimism, regulatory changes in the crypto sector are imminent.
The two most critical bills— the “GENIUS Act” related to stablecoins and the “CLARITY Act” regulating market structure—are expected to define clear boundaries for the industry.
This means that the long-uncertain regulatory environment for crypto, especially in the stablecoin sector, will see opportunities for standardized development. Clear rules have always been a key factor for institutional funds to enter, laying the groundwork for subsequent market explosion.
💰Tokenization Becomes a New Trend for Compliance💰
The pace of institutional entry is faster than expected! Coinbase observes in the report that the adoption rate of spot ETFs and Digital Asset Trusts (DAT) by institutions is soaring. Meanwhile, tokenized products as qualified collateral are becoming increasingly popular.
Behind this is the continuous increase in traditional financial institutions’ recognition of crypto assets—once difficult to mainstream, now they can be easily allocated via ETFs and used as collateral in financial activities.
The ongoing influx of institutional funds is transforming the player structure of the crypto market, accelerating the shift from “retail-led” to “institution-led” market dynamics.
💰AI + Crypto Collision💰
In 2026, technological innovation in crypto will focus on “practicalization”! Coinbase predicts that as zero-knowledge proof technology matures, market demand for privacy in crypto transactions will significantly increase.
Even more exciting is the cross-border integration of AI and crypto, which will deeply intersect in the field of proxy payments, potentially reconstructing payment processes and improving transaction efficiency.
Additionally, in response to long-term quantum threats, the industry will accelerate the exploration of post-quantum cryptography and other mitigation measures. The speed of technological iteration will directly determine the competitiveness of various blockchains.
💰Solana Abandons Meme Coins for RWA💰
The competition direction of mainstream blockchains will become clear in 2026!
Coinbase focuses on Ethereum’s upgrade dynamics, with upcoming tokens like Fusaka aimed at improving scalability, and tokens like Glamsterdam focusing on efficiency optimization. The core goal is to solve long-standing congestion and high fee issues.
Meanwhile, another popular blockchain, Solana, will bid farewell to the wild growth phase driven by meme coin speculation and shift toward deep development in proprietary AMM (Automated Market Maker) and RWA (Real-World Asset Tokenization).
The shift from “tech parameter competition” to “practical ecosystem value” will make it easier for high-quality projects to stand out.
💰Tokenization Market to Reach 18 Billion💰
The most shocking part of the report is Coinbase’s trillion-dollar prediction for stablecoins and tokenization markets!
The company forecasts that by 2028, the total market cap of stablecoins will soar to $1.2 trillion, disrupting the traditional payments industry with their efficiency and low costs.
Meanwhile, the tokenization market size will reach $18 billion, with government bonds and private credit serving as the core drivers.
This means that crypto assets will no longer be niche speculative tools but will be deeply integrated into the traditional financial system, becoming important carriers for payments, financing, and other fields. A new digital financial ecosystem is rapidly taking shape.
