I think buy and hold investing can be a great way to build wealth over the long term.
And ASX exchange traded funds (ETFs) can be particularly helpful because they make it easy to invest in a collection of companies in one trade.
But which ones could be top buy and hold candidates? Here are three that could be worth considering:

Global X AI Infrastructure ETF (AUD) (ASX: AINF)
The Global X AI Infrastructure ETF could be a strong option for investors that are wanting exposure to the buildout behind artificial intelligence (AI).
This fund focuses on the companies providing the physical infrastructure needed to support AI.
That includes semiconductor businesses, data centre equipment providers, networking companies, power infrastructure, cooling systems, and other businesses involved in keeping increasingly powerful computing systems running.
The long-term opportunity here is easy to understand. AI requires enormous amounts of computing power, and that means more chips, more data centres, more electricity, and more supporting infrastructure.
Rather than trying to identify which AI application will ultimately become the biggest winner, the Global X AI Infrastructure ETF gives investors exposure to the companies helping make the entire industry possible.
Vanguard FTSE Asia ex Japan Shares Index ETF (ASX: VAE)
Another ASX ETF to consider for the next decade is the Vanguard FTSE Asia ex Japan Shares Index ETF.
This fund gives investors exposure to companies across major Asian markets outside Japan. This includes businesses from countries such as China, Taiwan, South Korea, India, and Singapore.
Having this sort of exposure could be a very good thing. The region is home to enormous populations, rising incomes, major manufacturing hubs, leading technology companies, and increasingly important consumer markets.
Over the next decade, growing wealth across Asia could support demand for financial services, healthcare, technology, consumer products, travel, and many other industries. This bodes well for the holdings in the Vanguard FTSE Asia ex Japan Shares Index ETF.
VanEck Video Gaming and Esports AUD ETF (ASX: ESPO)
A final ASX ETF for investors to look at is the VanEck Video Gaming and Esports ETF.
Video games have grown from a relatively niche hobby into a huge global entertainment industry competing with film, television, music, and social media for people's time and money.
The industry has also changed significantly. Games can now generate revenue for years through downloadable content, subscriptions, in-game purchases, online communities, and recurring updates.
VanEck Video Gaming and Esports ETF gives investors exposure to companies involved in developing games, publishing them, creating gaming hardware, and supporting the wider industry. This includes giants such as Nintendo, Tencent, and Take-Two Interactive.
