If you are looking for an easy way to invest for the long-term, then exchange traded funds (ETFs) could be worth considering.
They allow investors to buy a large number of shares in one fell swoop, which removes the need to pick stocks.
With that in mind, here are three ASX ETFs that could be worth considering in May:

VanEck Morningstar International Wide Moat ETF (ASX: GOAT)
The first ASX ETF to look at is the VanEck Morningstar International Wide Moat ETF.
It gives investors exposure to international stocks that have sustainable competitive advantages. These are businesses expected to defend their market positions over long periods, supported by factors such as brands, scale, intellectual property, or network effects.
Its holdings include Etsy (NYSE: ETSY), Universal Music, and NXP Semiconductors (NASDAQ: NXPI).
Universal Music Group is a useful example of the type of company this ETF can hold. It owns one of the world's largest music catalogues, giving it exposure to streaming, licensing, and global consumption of music. As more listening shifts to digital platforms, valuable content libraries can remain powerful assets.
The VanEck Morningstar International Wide Moat ETF is not simply chasing growth. It is looking for businesses with staying power, which could make it good to buy and hold through to 2030.
Betashares Global Cybersecurity ETF (ASX: HACK)
Another ASX ETF that could be worth buying in May is the Betashares Global Cybersecurity ETF.
Cybersecurity has moved from a technology issue to a boardroom priority. As more business activity shifts online, companies need to protect identities, networks, data, and cloud-based systems.
This fund provides exposure to this growing area of spending through companies involved in cybersecurity software, hardware, and services.
Its holdings include Cisco Systems (NASDAQ: CSCO), Okta (NASDAQ: OKTA), and Palo Alto Networks (NASDAQ: PANW).
Okta shows how the sector is evolving. Its identity and access management tools help organisations control who can access their systems. That becomes more important as businesses use more cloud applications and employees work across different devices and locations.
With cyber threats unlikely to disappear, the Betashares Global Cybersecurity ETF offers exposure to an industry that could remain a priority for organisations for the rest of the decade.
Betashares Crypto Innovators ETF (ASX: CRYP)
A third ASX ETF for investors with a higher risk tolerance is the Betashares Crypto Innovators ETF.
It provides exposure to companies connected to the cryptocurrency and blockchain ecosystem. This is a more volatile area of the market, but it also gives investors access to a theme that could look very different by 2030.
Its holdings include Coinbase Global (NASDAQ: COIN), MicroStrategy (NASDAQ: MSTR), and Marathon Digital Holdings (NASDAQ: MARA).
Coinbase is central to this theme. It operates one of the largest crypto trading platforms globally and is tied to both investor activity and broader adoption of digital assets. If crypto markets mature and blockchain use cases continue to expand, companies like Coinbase could play an important role in the ecosystem.
The Betashares Crypto Innovators ETF will not suit every investor. But for those comfortable with volatility, it provides a simple way to gain exposure to a high-risk, high-upside corner of global markets.
