I think that buy and hold investing is one of the best ways to grow your wealth.

By putting your money in the market and letting it compound over many years, you can turn even modest amounts into something significant.

The good news is that buy and hold investing has become even easier in recent years due to the emergence of exchange-traded funds (ETFs).

These financial instruments allow you to buy a large number (sometimes thousands) of shares through a single investment.

But which ASX ETFs could be great long-term options for investors? Let's take a look at five to consider buying:

BetaShares Diversified All Growth ETF (ASX: DHHF)

The BetaShares Diversified All Growth ETF could be a great ASX ETF to hold onto for the long term. It gives investors easy access to ~8,000 large, mid, and small cap stocks from Australia, the United States, developed markets, and emerging markets. BetaShares, which recently named as one to buy, believes the fund has high growth potential, which could make it suitable for investors with a higher tolerance for risk.

iShares Global Consumer Staples ETF (ASX: IXI)

Another ASX ETF to look at is the iShares Global Consumer Staples ETF. As its name implies, this fund gives investors exposure to many of the world's largest consumer staples companies. These are generally regarded as low risk investment options that deliver steady returns rather than anything explosive. This is because they tend to perform well whatever is happening in the global economy. Among the fund's holdings are global giants Coca-Cola, Nestle, and Unilever.

BetaShares Cloud Computing ETF (ASX: CLDD)

A third ASX ETF that could be a good buy and hold option for investors is the BetaShares Cloud Computing ETF. Betashares, which also recently tipped this fund as one to buy, notes that "cloud computing has been one of the strongest-growing segments of the technology sector, and given much of the world's digital data and software applications are still maintained outside the cloud, continued strong growth has been forecast." Its holdings include Shopify and Zoom.

Betashares Global Quality Leaders ETF (ASX: QLTY)

Another ASX ETF to consider buying for 10 years is the Betashares Global Quality Leaders ETF. When you are making investment for the long term, it is never a bad idea to buy the highest quality companies you can find. Luckily, Betashares has made thing easy for investors by bundling together approximately 150 shares from across the globe that are judged to be the highest quality out there based on certain metrics. Betashares' chief economist, David Bassanese, named the ETF as one to buy.

VanEck Vectors Morningstar Wide Moat ETF (ASX: MOAT)

Finally, the VanEck Vectors Morningstar Wide Moat ETF could be a top ASX ETF to buy and hold. It looks for the type of companies that Warren Buffett would buy and then bundles them together for investors. These are companies with fair valuations and wide moats (or sustainable competitive advantages). Given the success Buffett has had with this strategy for decades with Berkshire Hathaway (NYSE: BRK.B), there's reason to believe this ASX ETF could deliver the goods over the long term.
