1. What Is the Altcoin Month Index?

The Altcoin Month Index serves as a key benchmark for assessing the overall performance of altcoins within the crypto market. Developed by the analytics platform Blockchaincenter, this index tracks whether the top 50 altcoins by market capitalization (excluding Bitcoin) have outperformed Bitcoin over the past 30 days. If more than 75% of these altcoins outperform BTC, the Altcoin Month Index rises above 75, indicating the onset of an “Altcoin Month.”

An index reading above 75 reflects a surge in market risk appetite, indicating that investors are increasingly allocating capital to higher-potential, higher-volatility altcoin projects.

2. Current Market Overview and Index Analysis

As of July 30, 2025, the Altcoin Month Index is at 80, signaling a classic “Altcoin Month” scenario. Bitcoin is consolidating around $118,000, while Ethereum remains steady near $3,700. With Bitcoin lacking short-term breakout momentum, investors are rotating capital into higher-return opportunities, making altcoins favored assets in this environment.

The latest broad-based rally in altcoins has been fueled by several factors, including booming new blockchain ecosystems, continued momentum in DeFi and GameFi, increasing hype around AI and Web3 social tokens, and innovative launches within stablecoin protocols.

3. Major Altcoin Prices and Market Movement

With the Altcoin Month Index at elevated levels, several well-known altcoins have posted strong gains. For example, Stellar (XLM), driven by rapid advances in cross-border payments and stablecoin integration, soared 74% over the past 30 days, currently trading around $0.53. Cardano (ADA), boosted by ongoing upgrades to its smart contract platform, climbed to $1.00. This represents a jump of over 23% within the month.

Ripple (XRP) saw investor confidence rise sharply following progress in its legal battle with the US SEC. Its price rose to $3.92, up about 21%. Meanwhile, Dogecoin (DOGE) has attracted renewed retail interest, with the price now at $0.33, attributable to ongoing community engagement.

Among newer projects, Sei (SEI) and Ethena (ENA) have garnered attention due to Sei’s high-performance blockchain and Ethena’s synthetic stablecoin mechanism, rising 27% and 21%, respectively. These standout performers have become popular rotation targets, supporting the elevated Altcoin Month Index.

4. Investment Strategies for Altcoin Month

For those new to the market, the following approaches may be considered:

• Focus on high-liquidity projects: Top-tier altcoins like SOL offer active trading and lower risk exposure.
• Use a dollar-cost averaging approach: To avoid timing the peak, invest at regular intervals to average your entry cost.
• Monitor hot sectors: AI, meme tokens, and blockchain gaming often lead short-term market surges.
• Set disciplined take-profit and stop-loss levels: Define your target gains and maximum acceptable losses in advance to maintain disciplined trading.

5. Risks and Precautions

While altcoins can see sharp rallies, their volatility is significantly higher than Bitcoin’s. Key risks include:

• The altcoin market often moves in tandem with Bitcoin and may drop sharply if BTC declines.
• Some newer projects may carry liquidity or security concerns.
• Steep price declines can result from diminishing airdrop expectations or unsuccessful mainnet launches.
• Avoid allocating all capital to a single asset—maintain a balanced portfolio and manage risk appropriately.
