The old investment saying 'Sell in May and go away' may not hold true in 2025. Although often associated with weaker markets, May has historically been a solid month for Bitcoin performance, having increased in 9 of the last 15 years.

Although 2025 still poses challenges, market data and sentiment indicate a shift beginning this month and according to AltcoinBuzz, the following four altcoins may perform strongly in May:

Cardano: Private Sidechain and ETF Potential

Cardano is gaining attention thanks to Midnight, a new privacy-focused sidechain aimed at balancing security with compliance. Project founder Charles Hoskinson stated that this could bring millions of new users to the platform.

Adding to the excitement is the increasing likelihood of a Cardano ETF. According to Polymarket, the approval rate for 2025 has risen from 60% to 70% in just one week.

Price Action and ADA's Targets

ADA is currently trading slightly above $0.70 and is now targeting to surpass the crucial level of $1. According to experts, ADA is likely to exceed its previous all-time high of $3.10.

Ondo Finance (ONDO): Leading the RWA Sector

Ondo Finance leads the Real World Asset (RWA) space after challenges from competitors like Mantra and OM. Recently, the Ondo team met with the SEC's cryptocurrency task force to discuss regulatory guidelines for the RWA space.

With the involvement of Paul Atkins, a pro-crypto advocate, the project's governance roadmap looks favorable, providing crucial clarity for the RWA regulatory process.

Price Forecast for ONDO and the RWA Market

With the current price around $0.92, ONDO may be undervalued considering the expected growth of the RWA market.

Sui Network: Growth and Ecosystem Innovation

The SUI ecosystem is thriving, up 50% in the past 30 days. The decentralized exchange (DEX) trading volume for this ecosystem surged 245% in Q1, despite the market trending downwards.

Improvements like offline cryptocurrency transfers using poor connectivity, announced at SUI's Base Camp event in Dubai, show that the team has strong technical leadership capabilities, expanding SUI's operational scope.

SUI Token Price and Potential to Reach New Highs

SUI Token is trading near $3.50, with a previous all-time high of $5.35. Continuous growth of the ecosystem token and developer activity could push SUI to new highs.

XRP: Notable ETF Catalysts

Ripple (XRP) is becoming the center of attention as the SEC may soon approve XRP futures ETFs, with high expectations for a subsequent spot ETF.

Currently, there are 17 ETF applications pending for XRP, part of a total of 72 cryptocurrency ETF applications that the SEC is reviewing. This could act as a catalyst for XRP's price, which is currently around $2.22.

XRP ETF Applications and ATH Goals

Just one approved XRP ETF could trigger a significant price surge, pushing XRP to a new ATH above $3.40, representing a substantial increase.
