If you are looking for growth shares to buy, but aren't overly keen on stock picking, then the solution could be exchange-traded funds (ETFs).

That's because ETFs allow investors to buy groups of shares in one go.

But which ASX ETFs could be good options for growth investors right now? Listed below are three that could be worth a closer look:

BetaShares Crypto Innovators ETF (ASX: CRYP)

The first ASX ETF to for growth investors to look at is the BetaShares Crypto Innovators ETF.

If you think cryptocurrencies are destined to fail, then stay away from this one. But if you believe they are the future, then this could be the one for you.

The BetaShares Crypto Innovators ETF provides investors with access to the leading players in the industry. This includes pure-play crypto companies, those whose balance sheets are held at least 75% in crypto-assets, and diversified companies with crypto-focused business operations.

Commenting on the fund, Betashares said:

CRYP provides 'picks and shovels' exposure to the companies building crypto mining equipment, crypto trading venues, and other key services that allow the crypto economy to thrive. CRYP invests in up to 50 crypto leaders such as Coinbase, Riot Blockchain, Microstrategy and more.

BetaShares Diversified All Growth ETF (ASX: DHHF)

Another top ASX ETF for growth investors to consider buying is the BetaShares Diversified All Growth ETF.

It was recently named as one to buy by BetaShares. It gives investors access to ~8,000 large, mid, and small cap growth stocks from across the globe.

Betashares sees the ETF as a great option for growth investors that want to take a hands-off approach to investing. It said:

If you prefer a 'hands-off' approach, an all-in-one diversified ETF like DHHF Diversified All Growth ETF offers a simple way to put your strategy into place. It provides exposure to around 8,000 small, medium, and large companies from Australia, developed markets, and developing markets. DHHF rebalances the portfolio quarterly to ensure allocations stay close to the strategic asset allocation targets.

BetaShares Global Cybersecurity ETF (ASX: HACK)

Finally, a third ASX ETF for growth investors to look closely at is the BetaShares Global Cybersecurity ETF.

This popular fund gives investors an easy way to invest in the growing cybersecurity sector, which could be a great area of the tech sector to be over the long term.

Betashares notes that demand for cybersecurity services is rising fast and the trend looks set to continue for some time to come. It said:

With cybercrime on the rise, the demand for cybersecurity services is expected to grow strongly for the foreseeable future. In one trade, get diversified, cost-effective exposure to global cybersecurity companies, a sector that is heavily under-represented on the ASX. The Fund's portfolio includes global cybersecurity giants, as well as emerging players, from a range of global locations.
