What is the Bitcoin dominance ratio, and how can this indicator be used?

在加密市场中，除了价格波动，比特币主导率也是不可忽视的关键指标。它反映了比特币在整个加密货币市场中的占比与影响力，能为投资者提供市场趋势的重要参考。主导率的变化常与资金流向相关，例如在山寨币季来临前，主导率下滑可能预示机会。了解这一指标的原理与意义，有助于你更精准地判断市场节奏，制定更具前瞻性的交易策略。

什么是比特币主导率?

比特币主导率指的是比特币在加密货币总市值中所占的百分比。简而言之，它显示了比特币的价值与所有其他加密货币的总和相比，在整个加密货币市场中占了多大比重。

例如，如果加密货币市场的总价值为2万亿美元，而比特币的市值为1.2万亿美元，那么比特币的主导率就是60%。

比特币的主导率在不断变化。它随着比特币的价格、山寨币的表现和整体市场情绪而变动。这是一个在 CoinMarketCap 和 CoinGecko 等网站上实时更新的动态指标，通常是跟踪加密市场脉搏人士的首选指标。

比特币主导率

为什么比特币的主导率对交易者很重要?

比特币主导率不仅仅是一个数字，它还是市场情绪的指南针：

1.市场信心

When the dominance of Bitcoin increases, it usually means that investors are shifting their funds to Bitcoin. This occurs frequently during periods of uncertainty or corrections, when Bitcoin is considered a “more secure” cryptocurrency.

2. Risk preference

When the dominance of Bitcoin decreases, it indicates that investors are diversifying their funds among various altcoins, suggesting increased confidence in the overall market and a shift towards a more risk-tolerant approach.

3. Trend prediction

Traders use changes in the share of Bitcoin in the market to predict trends. For example:

If Bitcoin prices rise and its dominance also increases, this often indicates a bull market dominated by Bitcoin.

If Bitcoin remains stable but its dominance decreases, then altcoins may start to rebound.

4. Portfolio strategy

Monitoring the dominance of Bitcoin can help you determine how to balance your portfolio between Bitcoin and altcoins based on market trends.

How to leverage the advantages of Bitcoin in trading

1. Identifying the market phase

Use the “dominance of Bitcoin” to understand the current market cycle:

When dominance increases and Bitcoin prices rise → a bull market dominated by Bitcoin. Prioritize Bitcoin in your portfolio.

When dominance decreases and Bitcoin prices remain stable or rise → early signs of an altcoin rally. Start shifting investments to high-quality altcoins.

The leading share is rising, while the price of BTC is falling—this indicates a bearish sentiment. Investors are withdrawing from altcoins and turning to Bitcoin as a safe haven.

The leading share is declining, along with the price of BTC—this reflects widespread risk aversion. Now might be a good time to hold stablecoins or reduce risk exposure.

2. Be mindful of the timing of buying and selling altcoins.

After Bitcoin shows signs of strength over the long term, a decline in its leading share often signals the beginning of an altcoin rally. This could be a sign that it’s time to start accumulating valuable altcoins.

On the other hand, if the leading share starts to rise sharply, while altcoins experience significant fluctuations, this could indicate that capital is flowing back into Bitcoin, and altcoins may face a correction.

3. Adjust your investment portfolio.

Many cryptocurrency investors use the “Bitcoin leading share” as a signal for rebalancing their portfolios.

When the leading share is extremely high, you might consider transferring some of your profits to altcoins that are undervalued.

When the leading share is very low, it’s time to reduce risk by shifting investments back to Bitcoin or stablecoins, in case there is a correction.

4. Combine this information with technical analysis.

For more accurate insights, combine the “Bitcoin leading share” with the following indicators:

BTC price trend.

Bitcoin chart patterns (e.g., ETH/BTC ratio).

Market volume and sentiment indicators.

This multi-level approach helps you better understand where funds are flowing and what the next moves might be.

比特币主导率的变化

多年来，比特币的主导率发生了巨大变化：

早年(2013-2016 年)，比特币的主导率超过90%，因为它是最主要的加密货币。

2017年，山寨币(如以太坊和瑞波币)的激增将主导率降至37%左右，标志着第一个大的“山寨季”。

2021年，DeFi 和 NFT 的崛起再次将比特币的主导率降至40%以下。

截至2025年年中，比特币的主导率约为63%，这表明在近期价格飙升和 ETF 获得批准的情况下，比特币重新获得了市场的主要份额。

这一历史模式显示了比特币的主导地位是如何随着市场周期和山寨币的创新趋势而起伏的。

比特币主导率的高低意味着什么?

比特币主导率高(超过60-65%)：

表明资本主要流向了比特币。

表示市场风险偏好较低。

通常发生在回调或以比特币为首的牛市中。

比特币主导率低(低于50%)：

表明投资者正在将资金转入山寨币。

这预示着人们对新项目和山寨币加密生态系统的信心不断增强。

这种情况经常出现在山寨季，即以太坊、Solana 或模因币等代币的表现优于比特币的时候。

总结：

主导率高= 比特币为王，其他币落后。

主导率低= 山寨币火热，市场投机性更强。

比特币主导率是一个判断山寨季的好指标吗?

是的，虽然这不是一个完美的预测指标，但比特币主导率是最流行的山寨季早期指标之一。

交易者如何使用该指标：

主导率下降+比特币价格稳定/上涨=山寨币可能开始了。

主导率急剧下降= 资本从比特币转向山寨币。

主导率突然反弹= 山寨季可能降温;比特币重振雄风。

从历史上看，山寨币的大反弹总是在比特币主导率急剧下降后产生的。观察这种趋势，尤其是与交易量、情绪和比特币价格走势一起观察，可以帮助你识别资金走向的早期迹象。
