XRP vs Solana vs Ethereum: Which Altcoin is the Best Buy for Upside Right Now?

XRP (CRYPTO: XRP), Solana (CRYPTO: SOL), and Ethereum (CRYPTO: ETH) all closed in the red last week. XRP and Solana both fell 3% to $1.39 and $83 respectively, while Ethereum fell 1% to $2,300. The recent downside has crypto investors worried, with many wondering which of the three coins is the one best buy at the moment.

Ethereum has historically performed well in May — closing higher in six of the past nine years — while XRP and Solana have had mixed performances. However, 2026 could be different as crypto assets struggle under pressure from external forces. We have analyzed which of these three coins currently have the best upside and what you should look for before making any investment decision.

To determine which coin offers the best opportunity, examine how each asset performed in May. Ethereum has the most consistent record of positive returns during this period. ETH has posted gains in May in six of the past nine years, with standout performances in 2016, 2017, 2019 and 2025.

During these years the Ethereum price gained 60%, 161%, 63%, and 41%, driven by different catalysts in each cycle—bull market momentum, ICO mania in 2017, network upgrades, and ETF inflows in 2025. When ETH ended May with a loss, like the 54% drop in 2018 and 2029, it was usually the pullback and 2029% market went to a strong run cooled.

Solana’s performance in May is less predictable. The coin’s strongest performances – a 30.5% increase in 2024 and 6% growth in 2025 – came when DEX volume, developer activity and meme coin cycles were strong. When those metrics weakened, Solana underperformed, as seen in 2022 and 2023 when it fell by 46% and 8% respectively. SOL historically does not start rallies in May, as its performance tends to follow momentum that is already in place.

XRP’s performance in May shows how volatile the market can be. Among all three coins, XRP recorded one of the highest gains in May—378% in 2017 and 40% in 2019. But the coin also recorded sharp declines, such as the 34% drop in 2021 and 28% decline in 2022.

The XRP price’s performance is linked to specific events. The rally to his $3.65 cycle high in July 2025 was a 76% gain from January, driven by a combination of catalysts including Trump’s pro-crypto stance, the SEC settlement closer to finalization, and ETF approval anticipation. Without those triggers, XRP struggles against bearish forces.

While historical trends favor Ethereum for consistent returns in May, market conditions in 2026 are different from previous cycles, leaving room for any of these three coins to deliver gains.

What to look for before choosing between XRP, Solana and Ethereum

Before deciding which of these three coins has the best setup, these are some key factors to look at.

XRP

Regulatory clarity was the most talked about issue XRP containers. The SEC and CFTC identified XRP as a digital commodity in March, but without legislation to seal that status — as the CLARITY Act– another administration could reverse this position.

The CLARITY Act is widely expected to drive the next XRP rally. US Senators Lummis and Thom Tillis are urging Senate Banking Committee Chairman Tim Scott to set a markup date for the bill. If this happens by the second week of May, XRP could rise back to $2, setting the stage for a move back to the $3.65 cycle high.

Solana

April was Solana’s first green month in 2026, with a modest increase of 1.30%. The Solana Foundation pushed the development of ecosystem through partnerships—such as the Shinhan Card transaction which opens stablecoin transactions to more than 28 million cardholders on Solana. Solana’s real asset ecosystem also reached a new high of $2.5 billion in total chain value.

With more partnerships and ecosystem developments, investor confidence can improve and the push The price of Solana above $100 – a profit of 20% from its current price.

Ethereum

May has historically been Ethereum’s strongest month, delivering an average return of 27%. To determine whether 2026 will follow the pattern, look beyond past performance and focus on ETF inflows and how the market is pricing the Glamsterdam upgrade.

SoSoValue data shows that Spot Ethereum ETFs recorded around $356 million in inflows in April, with early May already adding $101 million. That level of inflow indicates that institutional players are taking bullish positions, giving Ethereum a solid base.

Ethereum has a reputation for pricing early in upgrades, with the coin rallying in anticipation. The Glam Amsterdam upgradewhich will improve L1 scalability and decentralization is expected before the end of H1 2026. Expectations surrounding the upgrade could boost ETH’s momentum and push the price towards $3,000 – a 30% upside from current levels.

Which Altcoin Has the Best Advantage Right Now?

Ethereum has the most balanced setup because its positive performances in May did not rely on any single event. XRP’s chances could improve quickly if the CLARITY Act passes – the coin has always rallied on the back of a single big event, and the bill is exactly the kind of catalyst it needs to deliver outsized returns.

Solana’s chances for upside in May are unpredictable. The Solana Foundation’s developments and partnerships have not led to any price rally that holders would expect. With the enactment of the CLARITY Act and a favorable geopolitical environment, market sentiment could improve and pull Solana higher with it.

That said, if these events don’t happen in May, Ethereum is still the safest bet of the three cryptos based on its history.
