For investors looking to build wealth steadily over time, exchange-traded funds (ETFs) can be a great option.

A buy and hold strategy with the right ASX ETFs allows investors to benefit from long-term market trends while minimising the risks associated with stock picking and short-term market fluctuations.

By investing in ETFs, you gain exposure to a diversified portfolio of companies without the need for active management. Over a five-year horizon, this approach can deliver solid returns, particularly with funds that track high-quality global businesses.

Here are three ASX ETFs that could be worth buying and holding for the next five years.

Betashares Nasdaq 100 ETF (ASX: NDQ)

For those looking to gain exposure to the world's most innovative and fast-growing technology companies, the Betashares Nasdaq 100 ETF could be the way to do it. This fund tracks the Nasdaq-100 Index, which includes 100 of the largest non-financial companies listed on the Nasdaq exchange in the United States.

The Nasdaq 100 is home to many of the world's tech giants, including Apple (NASDAQ: AAPL), Microsoft (NASDAQ: MSFT), Amazon (NASDAQ: AMZN), and Nvidia (NASDAQ: NVDA). Over the past decade, technology stocks have outperformed most other sectors, benefiting from megatrends such as cloud computing, artificial intelligence, and e-commerce. While they can be volatile in the short term, their long-term growth potential arguably makes them attractive for a five-year investment horizon.

Vanguard MSCI Index International Shares ETF (ASX: VGS)

For a well-diversified global equities option, the Vanguard MSCI Index International Shares ETF could be a strong contender. This ASX ETF provides broad exposure to over 1,400 large and mid-cap companies across developed markets, including the United States, Europe, and Asia.

The fund offers a balanced approach to global investing by spreading risk across multiple sectors and regions. It includes companies such as Alphabet (NASDAQ: GOOG), Nestlé, Toyota (NYSE: TM), and Johnson & Johnson (NYSE: JNJ), providing exposure to industries ranging from healthcare and consumer goods to finance and technology. This makes it a solid core holding for investors looking for steady long-term growth with lower volatility compared to a tech-heavy ETF.

Betashares Global Cash Flow Kings ETF (ASX: CFLO)

A third potential option for long-term investors is the Betashares Global Cash Flow Kings ETF. This ASX ETF focuses on global companies with strong free cash flow, which is a key indicator of financial health and resilience.It was recently tipped as one to buy by analysts at Betashares.

The fund includes high-quality businesses that generate consistent cash flow, making them well-positioned to weather economic downturns and deliver stable returns. Companies with strong cash flow tend to reinvest in growth, pay dividends, and maintain financial stability, which can help investors achieve solid performance over time.
