Bitcoin or Ethereum? We asked ChatGPT which crypto is a better buy for 2025 H2

Bitcoin (BTC) and Ethereum (ETH) have both experienced substantial gains and unprecedented institutional demand in 2025.

However, while both cryptocurrencies are up significantly since January, they still present two rather diverse investment options.

Namely, Bitcoin hit a new all-time high in July and still remains the primary hedge as the so-called digital gold, while Ethereum represents a popular smart-contract choice and enjoys the reputation of a potential value pick.

To see which of the two assets might be the better pick this year, we consulted OpenAI’s ChatGPT-4.5. Here are its insights.

BTC analysis

At the time of writing, BTC was trading at approximately $114,560, with a market cap of $2.27 trillion.

From the get-go, ChatGPT noted Bitcoin’s position as the dominant crypto asset and digital store of value.

Indeed, institutional demand remains a major driving force, especially with spot Bitcoin ETFs (exchange-traded funds) attracting consistent capital inflows.

From a regulatory standpoint, the cryptocurrency also benefits from relative clarity compared to some of its competitors, being broadly classified as a commodity in some key jurisdictions.

As for the potential price targets, the artificial intelligence (AI) model predicted BTC could trade above $120,000 again by the end of the year, provided the asset’s reputation and demand remain intact. On the contrary, heavy ETF outflows, market pullbacks, and regulatory headwinds could see the price tank to a $55,000–$65,000 range.

Accordingly, the chatbot concluded that Bitcoin was the smarter pick for those seeking lower volatility, institutional support, and long-term hedge potential.

ETH analysis

Ethereum, on the other hand, was trading at around $3,552 at press time, with a market cap of nearly $429.4 billion.

Analyzing the second-largest cryptocurrency, ChatGPT highlighted that Ethereum remains a cornerstone of the decentralized application (dApps) ecosystem.

Moreover, its dominance in areas like decentralized finance (DeFi), non-fungible tokens (NFTs), and tokenization also continues to grow, with updates like EIP-4844 (Proto-Danksharding) and the maturing Layer 2 (L2) ecosystem significantly improving scalability on the network.

Nonetheless, Ethereum faces ongoing regulatory uncertainty, and it’s still unclear whether it could be classified as a security.

Looking into potential price targets, the AI predicts the cryptocurrency could even hit $9,000 if regulation becomes more favourable, particularly when it comes to ETH ETFs. Staking slowdowns, regulatory uncertainty, and overall altcoin weakening, however, could see the price go as low as $3,000.

Overall, the chatbot concludes that Ethereum could have more upside potential than Bitcoin if the altcoin market sentiment continues to improve in the following months.

BTC vs. ETH: The bottom line

Comparing the two cryptos, ChatGPT concluded that if your investment strategies lean toward lower volatility, long-term capital preservation, and broader institutional support, Bitcoin may be the more suitable option in H2 2025.

However, if you’re seeking exposure to DeFi and wish to focus on staking and network innovation, Ethereum is also a solid choice.
