比特币是什么？

比特币是第一种加密货币，由化名中本聪于 2009 年创建，是按市值计算最大的加密货币（CoinGecko 上的实时排名）。它引入了区块链，主要用作价值储存和点对点支付网络。比特币使用工作量证明共识，供应量固定上限为 2100 万枚。.

什么是以太坊？

Ethereum is an open-source blockchain with smart contract support, launched in 2015 by Vitalik Buterin and co-founders. It is the base layer for most of DeFi and NFTs. Since The Merge in September 2022, Ethereum runs on Proof of Stake. It has no fixed supply cap, but EIP-1559 burns part of every transaction fee.

关键差异

Bitcoin is designed as a decentralized store of value and payment network. Ethereum is a programmable platform for smart contracts, DeFi and dApps.

Bitcoin uses energy-intensive Proof of Work mining. Ethereum moved to Proof of Stake in September 2022, cutting its energy use by about 99.95% according to ethereum.org.

Bitcoin has a fixed supply of 21 million coins. Ethereum has no hard cap but burns part of every transaction fee, so its supply can shrink when the network is busy.

Ethereum confirms blocks about every 12 seconds, against roughly 10 minutes for Bitcoin.

Bitcoin's scripting language is deliberately limited for security. Ethereum's EVM runs general-purpose smart contracts, which enables complex applications.

您应该选择哪一个？

比特币和以太坊服务于不同的目的，通常被视为互补而非竞争对手。比特币主要作为一种稀缺的价值储存手段：供应量固定，且在加密货币中拥有最长的历史记录。以太坊是大多数DeFi和Web3的结算层，提供了比特币刻意避免的可编程性。许多投资者将两者都作为多元化加密货币投资组合的一部分持有。.

常见问题

比特币比以太坊更好吗？
两者并没有客观上的优劣，它们各自服务于不同的目的。比特币主要是价值储存和数字黄金，而以太坊是去中心化应用和智能合约的平台。更好的选择取决于你是看重稀缺性和简洁性（比特币），还是看重可编程性和生态系统的广度（以太坊）。.
以太坊能在市值上超越比特币吗？
This scenario, known as "the flippening," has been debated for years. Ethereum has a much larger ecosystem of dApps and DeFi protocols, but Bitcoin has kept a clear lead in market capitalization and is widely viewed as the main crypto store of value. As of September 2026, Bitcoin holds the number one position by market cap; check CoinGecko for the live ranking.
以太坊为何转向权益证明？
Ethereum moved to Proof of Stake with "The Merge" in September 2022 to cut energy consumption by about 99.95%, let ETH holders secure the network by staking, and prepare the ground for later scaling upgrades such as data blobs (EIP-4844) and danksharding.
BTC或ETH哪一个的交易费用更低？
Both networks have variable fees that depend on congestion. On-chain, fees on either chain can range from well under a dollar in quiet periods to tens of dollars at peak demand. Ethereum Layer 2 networks such as Arbitrum and Base process transactions for a few cents or less, while Bitcoin has the Lightning Network for cheap off-chain payments.
我应该投资比特币还是以太坊？
This is not financial advice. Many investors hold both because they play different roles. Bitcoin is often viewed as a macro asset similar to digital gold, while Ethereum offers exposure to the growth of DeFi, NFTs and Web3. Consider your risk tolerance and investment goals, and do your own research before investing.
