Long-term investing does not need to be complicated. Rather than trying to pick the next big winner, many investors focus on building a portfolio that can grow steadily over time.
Exchange traded funds (ETFs) can play a key role in that approach by offering diversification, simplicity, and exposure to powerful global trends.
But which funds could be top buy and hold picks this month?
Here are five ASX ETFs that could be worth buying in April and holding until 2036.

iShares S&P 500 ETF (ASX: IVV)
The first ASX ETF to consider for the long term is the iShares S&P 500 ETF.
This ETF tracks the S&P 500, giving investors exposure to 500 of the largest stocks in the United States. But more importantly, it provides access to businesses that have proven their ability to scale, adapt, and lead globally.
The index itself evolves over time, naturally shifting towards companies that are performing well. That means investors are not locked into yesterday's winners but instead continue to gain exposure to the leaders of tomorrow.
For a long-term portfolio, the iShares S&P 500 ETF offers a strong foundation built on some of the world's most successful companies.
Vanguard MSCI Index International Shares ETF (ASX: VGS)
Another ASX ETF that could be a top pick is the Vanguard MSCI Index International Shares ETF.
It expands the opportunity set beyond the US by providing exposure to developed markets around the world. This includes companies across Europe, Japan, and other major economies.
What makes this ETF appealing over a 10-year period is diversification. Different regions can perform well at different times, and the Vanguard MSCI Index International Shares ETF allows investors to benefit from a broader range of economic drivers.
BetaShares Nasdaq 100 ETF (ASX: NDQ)
A third ASX ETF to consider is the popular BetaShares Nasdaq 100 ETF.
It focuses on the Nasdaq 100, which is heavily weighted towards technology and growth companies. These businesses are at the forefront of innovation, including areas such as artificial intelligence, cloud computing, and digital services.
While this can lead to periods of volatility, it also creates the potential for strong long-term returns as these trends continue to develop.
BetaShares Global Cybersecurity ETF (ASX: HACK)
Another ASX ETF that could be worth considering is the BetaShares Global Cybersecurity ETF.
Cybersecurity is becoming increasingly important as more of the world moves online. Every connected system, from businesses to governments, requires protection from digital threats.
The BetaShares Global Cybersecurity ETF invests in companies that provide these essential services. While these businesses often operate behind the scenes, their role is critical to the functioning of the modern economy.
Over the next decade, demand for cybersecurity solutions is likely to grow materially, making this ETF a way to invest in that ongoing need.
BetaShares Asia Technology Tigers ETF (ASX: ASIA)
A final ASX ETF to consider is the BetaShares Asia Technology Tigers ETF.
This ETF provides exposure to leading technology stocks across Asia, offering a different perspective on digital growth compared to Western markets.
Many of its holdings operate large-scale platforms that combine multiple services into a single ecosystem, driving strong user engagement and monetisation opportunities from the region's growing middle class.
For investors with a long time horizon, the BetaShares Asia Technology Tigers ETF offers exposure to a region that is likely to play an increasingly important role in the global technology landscape.
