If you're looking to build long-term wealth, buying and holding high-quality exchange-traded funds (ETFs) can be a smart and stress-free strategy.

While short-term market fluctuations can be unpredictable, history shows that quality investments tend to rise over time. This is particularly the case in sectors being supported by long-term structural trends.

The ASX offers a range of ETFs that provide exposure to industries with strong future growth potential. Here are three excellent ASX ETFs to consider:

Betashares Nasdaq 100 ETF (ASX: NDQ)

The Betashares Nasdaq 100 ETF provides investors with exposure to 100 of the largest non-financial companies listed on the Nasdaq stock exchange. This index is home to some of the world's most innovative and fastest-growing companies, particularly in the technology sector.

One key holding is Apple (NASDAQ: AAPL). As one of the world's most valuable companies, Apple continues to generate massive revenue from its iPhones, services, and growing presence in artificial intelligence and wearables.

Another key holding is Nvidia (NASDAQ: NVDA). It is a global leader in artificial intelligence (AI) computing and graphics processing units (GPUs). This puts it at the forefront of industries like gaming, data centres, and autonomous driving.

With its strong track record and exposure to industry-leading companies, the Betashares Nasdaq 100 ETF could be a solid long-term ASX ETF investment.

For investors looking to tap into the rapid growth of Asia's technology sector, this ASX ETF provides exposure to 50 of the region's largest tech companies. This includes companies from China, South Korea, Taiwan, and other key markets.

Asia is home to some of the world's most innovative tech firms and the region's digital economy is expected to expand significantly over the next decade. This bodes well for the companies included in the Betashares Asia Technology Tigers ETF.
