If you are planning to make some buy and hold investments in 2025, then the exchange-traded funds (ETFs) in this article could be worth considering.

Let's take a closer look at them and see what sort of shares they allow you to invest in. They are as follows:

Betashares Global Cash Flow Kings ETF (ASX: CFLO)

The first ASX ETF that could be a good buy and hold option is Betashares Global Cash Flow Kings ETF. The fund manager, Betashares, notes that companies that generate high levels of free cash flow have a tendency of outperforming the market over the medium to long term. This ETF focuses on global companies with strong free cash flow and includes giants such as Alphabet (NASDAQ: GOOG) and Visa (NYSE: V). Betashares recommended the ETF as one to buy for 2024 and highlights that it could serve as a core exposure to global equities.

BetaShares Global Cybersecurity ETF (ASX: HACK)

Another top buy and hold option could be the BetaShares Global Cybersecurity ETF. It provides investors with access to the leading players in the global cybersecurity industry. This could be a great place to be over the long term. Betashares highlights that "an estimate of the total addressable market by McKinsey suggests that the cybersecurity market is $1.5-$2.0 trillion globally, and at best only 10% penetrated with a very long runway for growth."

Betashares Global Uranium ETF (ASX: URNM)

A third ASX ETF for investors to consider for the long term is the Betashares Global Uranium ETF. It gives investors access to the leading companies in the global uranium industry. This includes locally listed uranium miners Boss Energy Ltd (ASX: BOE) and Paladin Energy Ltd (ASX: PDN). With nuclear power seen as key to the decarbonisation of the planet, these companies look well-placed to benefit from increasing demand for uranium.

iShares S&P 500 ETF (ASX: IVV)

Another ASX ETF that could be a top buy and hold option is the iShares S&P 500 ETF. It allows investors to buy a slice of 500 of the largest listed companies on Wall Street. This means that you will be buying companies from a range of different industries and sectors. This includes giants such as Apple, Exxon Mobil Corp, and Microsoft.

Vanguard MSCI Index International Shares ETF (ASX: VGS)

Finally, the Vanguard MSCI Index International Shares ETF could be a top buy and hold option. It gives investors access to a whopping ~1,500 of the world's largest listed companies (excluding Australia). This is such a large number of shares that it can almost instantly diversify a portfolio. It also means that investors can gain easy exposure to global economic growth.
