#Gate广场五月交易分享 Crypto Market Rebound: What Are the Eight Most Important Indicators to Watch Right Now

Recently, the crypto market has been recovering. Professional "market indices" such as total market capitalization, BTC market share, Fear & Greed Index, Altcoin Season Index, and others can help investors comprehensively understand the current crypto market trends from the perspectives of capital flow, market sentiment, and risk appetite.
1. Total Market Capitalization of Crypto
According to TradingView data, the current total market capitalization of crypto is $2.66 trillion.
Why should we pay attention to changes in total market capitalization?
Because the essence of a bull market is new capital inflow. If only BTC is rising but the overall market isn't, it’s just internal capital rotation and doesn’t indicate a true bull market. If the total market cap continues to reach new highs, it suggests new funds are entering, signaling a bull market. This is often accompanied by ETF inflows, stablecoin issuance increases, and rising market sentiment. If the total market cap remains flat, it indicates a stockpile game stage, characterized by rapid sector rotation and poor altcoin sustainability. If the total market cap declines, it means funds are leaving, investor risk appetite is cooling, and a bear market may be approaching.
2. BTC Market Share
According to TradingView data, the current BTC market share is 60.60%.
BTC market share is one of the most core indicators in the entire crypto market, representing how much of the total crypto funds are held in BTC. This indicator directly determines whether capital is in BTC or flowing into altcoins.
An increase in BTC market share indicates a preference for BTC, such as during institutional buying phases. This usually occurs early in a bull market, when market risk is lowest and liquidity is high. During panic, funds tend to flow back from altcoins into BTC as a safe haven.
A decrease in BTC market share indicates the arrival of altcoin season, with funds shifting from BTC to altcoins, starting with ETH, SOL, and gradually moving into AI, Meme coins, and others. Historically, after BTC rises, ETH often catches up. Then large-cap altcoins take off, followed by mid-cap and small-cap coins, with Meme coins causing market bubbles to peak…
3. Total Market Cap of Cryptocurrencies Excluding Bitcoin
According to TradingView data, the current total market cap of cryptocurrencies excluding Bitcoin is $1.05 trillion.
If the total market cap excluding Bitcoin is rising, it indicates the start of altcoin season. Specifically, investors are willing to buy altcoins, and risk appetite is increasing, signaling the onset of altcoin season. The total market cap excluding Bitcoin also serves as a risk appetite indicator: the higher it is, the more willing the market is to take on high risk.
4. Fear & Greed Index
According to Alternative data, the current Fear & Greed Index is 38, indicating fear.
The traditional market Fear & Greed Index was developed by CNNMoney to measure two main emotions driving investor behavior and influencing stock buying. The crypto Fear & Greed Index is based on CNNMoney’s stock market fear and greed index, providing lessons on potential pitfalls of profit-taking and valuable buy-and-hold strategies.
In crypto, the index ranges from 0 to 100. Lower scores indicate stronger fear; higher scores indicate greed. Extreme fear is between 0-24, fear is 25-49, neutral is around 50, greed is 51-74, and extreme greed exceeds 75. When the index shows extreme fear, many market participants are selling, leading to price drops, which can be good buying opportunities—buying the dip. When measuring extreme greed with “Fear of Missing Out” (FOMO), it can signal a market top, as retail investors become overly euphoric.
This index is also used as a contrarian indicator: markets tend to bottom out in extreme fear and top out in extreme greed. It confirms the well-known saying: “Buy when no one is interested.”
5. Altcoin Season Index
According to CoinMarketCap data, the current Altcoin Season Index is 48.
This index measures how many of the top 100 cryptocurrencies are outperforming BTC. If the index exceeds 75, it indicates an altcoin season; if below 25, the market is dominated by BTC.
A high index suggests more capital distribution, increased risk appetite, and a market entering a full-blown hype phase. Conversely, a low index indicates capital is concentrated in BTC, and even if altcoins perform, it’s only localized.
During altcoin season, clear market features include: altcoin dominance rising, rapid price increases, and FOMO. Some analysts believe that the presence of ETFs may weaken this cycle compared to historical altcoin seasons.
6. USDT Market Share
According to TradingView data, the current USDT market share is 7.152%.
This reflects the proportion of stablecoin market value within the crypto market. If this index rises, it indicates increased risk aversion, as investors move funds into USDT, a bearish signal. If it falls, it suggests risk appetite is returning, a bullish sign.
7. ETF Capital Flows
According to Farside data, recent seven-day ETF capital flows are mainly inflows.
Significant ETF inflows suggest bullish sentiment on Wall Street, institutional participation, and additional capital entering BTC, which is positive for the market. Conversely, large outflows indicate declining institutional risk appetite and potential market corrections.
8. Open Interest Index of Contracts
Data from Coinglass shows the total open interest across platforms.
This is a core sentiment indicator in the derivatives (contracts) market, reflecting leverage levels and the intensity of long vs. short battles. It’s an indicator of market sentiment and capital positioning.
An increasing index suggests more funds are entering the derivatives market, but it also carries risks: high leverage can lead to liquidations, slippage, and waterfall declines. Excessive leverage accumulation makes the market more volatile and prone to sudden crashes and liquidations.
In summary, the current market shows clear signs of recovery, with some indicators already exhibiting early bull market features—BTC momentum strengthening, localized altcoin rallies, but not yet a broad rally. However, these indices only reflect current sentiment and capital flow; investors should also closely monitor macro factors like Federal Reserve policies and geopolitical risks in the Middle East, which could impact the market.
