3 Cryptocurrency Investor Trends You Need to Know for the Second Half of 2025

It's been a strange year for the crypto market. After a hot start to 2025, every major cryptocurrency continues to be whipsawed by the constant ups and downs of tariffs and global trade.

What can investors expect in the second half of the year? According to the new Motley Fool Money 2025 Cryptocurrency Investor Trends Survey, investors remain bullish on the future prospects of crypto, especially Bitcoin (CRYPTO: BTC). Let's take a closer look.

Bitcoin could double in value in 2025

Bitcoin has been front and center throughout the year. Even with the volatility of the current tariff situation, investors remain very bullish about the cryptocurrency's prospects.

According to the Motley Fool Money 2025 Cryptocurrency Investor Trends survey, 68% of U.S. adults who currently hold crypto in their portfolio think that Bitcoin could hit $200,000 by the end of 2025. Based on its current price of $105,000, that suggests that Bitcoin could double in value over the next six months.

Even U.S. adults who don't own crypto in their portfolios are surprisingly bullish about Bitcoin. For example, 25% of them also think that Bitcoin could hit $200,000 by the end of 2025. Another 49% are undecided. Only 26% think it's unlikely.

As a result, investors are likely to continue to buy the dip for the rest of the year. Anytime Bitcoin loses 10% or more of its value, they'll view it as a buying opportunity. And, indeed, this is what we've already seen in the first half of the year, with money continuing to flow into the spot Bitcoin exchange-traded funds (ETFs) from retail investors.

Solana and XRP could rally if new ETFs are approved

Currently, only Bitcoin and Ethereum (CRYPTO: ETH) have spot ETFs. However, one big story of the year has been the potential for other major cryptocurrencies to get spot ETFs of their own. Two that are often mentioned are Solana (CRYPTO: SOL) and XRP (CRYPTO: XRP).

These new spot ETFs could be a game changer. They make buying crypto as easy as buying your favorite tech stock. You can open up an app on your phone, hit a button, and get exposure to Bitcoin instantly. According to the Motley Fool Money crypto survey, "I don't understand how to buy it" remains one of the major barriers to investing in crypto, and spot ETFs help solve this problem.

That leads me to think there will be a rally in Solana and XRP later in the year. That's when the SEC is scheduled to sign off on new spot ETF applications for both cryptos. As soon as these start trading, it could lead to a wave of new investor money flowing into them.

Ethereum may continue to underperform

Ethereum is still the world's second-largest cryptocurrency, and continues to be an important part of the White House's crypto strategy. So why does Ethereum continue to lag the market? Even after a mini-rally in May, Ethereum is still down 20% for the year.

By parsing the data and responses in Motley Fool Money's crypto survey, I might have uncovered the answer: Investors just don't like Ethereum. They can't figure out what to do with it, and it doesn't generate the sort of big, splashy news headlines that can grab their attention.

According to the survey, 36% of respondents who don't own crypto said they "don't know what to do with it." Overall, only 11% of respondents said they understood how crypto works. Bitcoin is easy to explain -- it's "digital gold." But what, exactly, is Ethereum?

Moreover, survey respondents appeared to show a clear preference for big, splashy news headlines. For example, as soon as Bitcoin hit the $100,000 price level, it immediately helped to pull in investors who might have otherwise ignored crypto. Bitcoin hitting $100,000 is the type of headline that's tailor-made to float across the chyron of a TV.

Or, take the example of Elon Musk joining the Trump administration earlier this year. Even though Musk had no direct role in the White House's crypto policies, the overwhelming sentiment of survey respondents was that just having him aboard would somehow be good for crypto.

Ethereum hasn't been able to deliver anything close to a splashy $100,000 news headline or a high-profile public figure like Elon Musk. The biggest news this year has been a new blockchain upgrade in May. As a result, investors just aren't interested. Ethereum may continue to underperform the market until a new narrative emerges.

What happens next for crypto?

In the crypto market, sentiment can change on a dime. Now that Musk has left the White House, for example, will investors become more or less bullish on crypto? And how long are investors willing to wait for Bitcoin to double in value, if it shows signs of stumbling over the summer?

That being said, the new Motley Fool Money crypto survey is a great temperature check on what crypto investors are thinking right now. Using the survey response data, it's possible to put together some compelling narratives about where Bitcoin, Ethereum, Solana, and XRP might be headed in the second half of 2025.
