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.

Recently, I noticed an interesting trend in how people choose stablecoins.  
Before, everyone just picked the first one they saw, but now it's clear that the market is distinctly differentiating based on various criteria.  
Stablecoins are essentially cryptocurrencies that maintain a stable value, usually pegged to the US dollar.  
And honestly, the options now are much greater than they were a couple of years ago.  
Tether (USDT) still dominates the market.  
Its market capitalization has already surpassed $189 billion, making it the most stable cryptocurrency by usage volume.  
It's available everywhere — on Ethereum, Tron, Solana.  
Most traders use it for trading and as a reserve currency on DeFi platforms.  
But when it comes to transparency, USD Coin (USDC) stands out.  
Its capitalization is now around $78 billion.  
USDC is known for regularly undergoing audits and being fully backed by reserves.  
It's often chosen by those working with traditional finance or valuing regulatory compliance.  
It operates on Ethereum, Solana, Avalanche, and other chains.  
There's also an interesting option — DAI.  
This is a decentralized stablecoin from the MakerDAO protocol with a capitalization of about $4.4 billion.  
Its feature is that it’s backed by cryptocurrencies, not fiat.  
For those seeking a highly decentralized solution, this is a good choice.  
TrueUSD (TUSD), with its $493 million capitalization, also deserves attention.  
It regularly undergoes third-party audits and is gaining popularity due to its transparency.  
Experts point out several key factors when choosing.  
First, transparency and regular reserve audits — USDC and TUSD are leaders here.  
Second, if decentralization is needed, DAI and Frax (around $46 million capitalization) offer interesting models.  
Frax, by the way, is a hybrid stablecoin — partially collateralized, partially stabilized algorithmically.  
There's also USDP (Paxos Standard) with a capitalization of $40.55 million and GUSD (Gemini Dollar) with $170 million — both are fully regulated and backed by reserves in American banks.  
What’s important to consider: if you frequently transfer between chains, check which blockchains support the stablecoin you need.  
USDT is everywhere, but fees vary.  
USDC is also widely supported.  
If you work in DeFi and want the most stable cryptocurrency with full decentralization, DAI is your choice.  
In my opinion, by 2026, the stablecoin ecosystem has become much more mature.  
Each of them finds its niche — some for trading, some for payments, some for DeFi applications.  
Personally, I track several simultaneously depending on what I’m doing.  
I recommend you not to stick to just one option, but to see which one suits your specific needs.  
On Gate, you can see the current quotes for all these assets and choose the most convenient for yourself.
