A new month is here, which means it could be an ideal time to reassess your portfolio and consider adding some exchange-traded funds (ETFs) that could deliver long-term growth.

But which funds could be buys this month?

Below are three standout ETFs listed on the ASX, each offering unique exposure to key sectors and opportunities for 2025 and beyond. Here's what you need to know about them:

BetaShares Crypto Innovators ETF (ASX: CRYP)

For investors keen on the cryptocurrency sector but reluctant to dive directly into digital assets, the BetaShares Crypto Innovators ETF offers a compelling alternative.

This ETF focuses on companies intricately tied to the cryptocurrency ecosystem. Its portfolio spans pure-play crypto businesses, firms with substantial holdings in crypto-assets, and diversified players active in crypto-centric fields such as blockchain, payment platforms, and mining operations.

As cryptocurrency adoption accelerates and the ecosystem matures, these companies could benefit significantly.

This ETF offers an accessible way to ride the wave of crypto innovation without directly owning volatile assets. However, investors should remain mindful of the sector's inherent risks and volatility.

BetaShares Australian Quality ETF (ASX: AQLT)

For those seeking a quality-driven approach to investing in the Australian market, the Betashares Australian Quality ETF stands out. It was recently tipped as one to buy by the Betashares team.

This ETF offers exposure to the largest Australian companies, but rather than weighting them by size, it prioritises quality attributes. These include high returns on equity, low leverage, and stable earnings. Companies exhibiting these attributes have historically outperformed broader benchmarks while also demonstrating defensive qualities.

The fund's top holdings include Commonwealth Bank of Australia (ASX: CBA) and Pro Medicus Limited (ASX: PME), two companies recognised for their strong fundamentals and consistent performance.

BetaShares Asia Technology Tigers ETF (ASX: ASIA)

If you're positive on Asia's economic trajectory, the BetaShares Asia Technology Tigers ETF offers exposure to some of the region's most dynamic technology companies.

This ETF focuses on firms driving the tech revolution across Asia, excluding Japan. It includes giants such as Alibaba (NYSE: BABA) and PDD Holdings (NASDAQ: PDD), which are at the forefront of e-commerce, digital transformation, and advanced technologies. With a rapidly growing middle class and an increasingly tech-savvy population, the region's technology sector presents significant growth potential.

By investing in this ETF, you gain access to the growth engines of Asia's digital economy while spreading your risk across multiple companies and industries.
