With crypto markets experiencing a strong rebound in recent months, many digital assets have surged in value. Yet, even amid this rally, several high-potential cryptocurrencies continue to trade under $1. In fact, as we move through 2025, six of the top 20 cryptocurrencies by market capitalization remain priced below one dollar. This presents an intriguing opportunity for investors looking to diversify their portfolios with affordable yet promising blockchain projects.
Among these low-priced cryptos, three stand out due to their strong fundamentals, ecosystem growth, and long-term potential: Polygon (MATIC), XRP, and Cardano (ADA). While each comes with unique risks and challenges, they also offer compelling narratives that could drive future appreciation.
Let’s explore what makes these sub-$1 cryptos worth watching—and whether they deserve a place in your investment strategy.
Polygon: Scaling Ethereum’s Future
Polygon is a Layer 2 scaling solution designed to enhance the performance and reduce transaction costs on the Ethereum network. As Ethereum remains the leading platform for decentralized applications (dApps) and smart contracts, Polygon benefits directly from its success. The tighter integration between the two networks means that any growth in Ethereum usage—especially in areas like DeFi and NFTs—can positively impact Polygon's adoption.

However, competition in the Layer 2 space has intensified. Projects like Arbitrum, Optimism, and zkSync are gaining traction, challenging Polygon’s early-mover advantage. Additionally, the NFT market—once a major driver of Polygon’s activity—has slowed significantly. Without a robust recovery in NFT trading volume, Polygon may struggle to attract new users at scale.
Despite launching a major strategic update known as Polygon 2.0 in mid-2023, the project has seen only modest gains, with MATIC rising just 12% over the year. Rebranding efforts and technical upgrades haven’t yet convinced investors en masse. Still, Polygon continues to partner with major institutions and governments for real-world blockchain applications, which could unlock new use cases beyond speculative trading.
For now, Polygon remains a high-risk, high-reward play tied closely to Ethereum’s trajectory and broader market sentiment.
XRP: Legal Battles and Market Uncertainty
XRP, developed by Ripple Labs, has long been touted as a fast and efficient digital asset for cross-border payments. Unlike many cryptocurrencies focused on decentralization or smart contracts, XRP aims to serve financial institutions by enabling near-instant international settlements at low cost.
This practical utility has earned XRP a loyal following and a spot among the most recognized cryptos worldwide. Year-to-date in 2025, XRP has gained 82%, reflecting renewed optimism. However, its long-term price performance remains muted compared to its all-time highs reached back in early 2018.
The biggest overhang on XRP is its ongoing legal battle with the U.S. Securities and Exchange Commission (SEC). Since December 2020, the SEC has argued that XRP is an unregistered security—a classification that could severely limit its trading and development in U.S. markets. Although some rulings have favored Ripple, the case is far from resolved and is now expected to extend into late 2025.
Legal defense costs have mounted, with Ripple executives estimating expenses could surpass $200 million. This financial strain adds further uncertainty to XRP’s outlook.
While a favorable verdict could trigger a significant price surge, investing in XRP today remains highly speculative. It’s best suited for those who believe in its eventual regulatory clearance and continued adoption by banks and payment providers.
Cardano: The Quiet Performer
Often dismissed as “slow” or “boring,” Cardano has cultivated a reputation for methodical development rather than hype-driven launches. Founded by Charles Hoskinson, a co-founder of Ethereum, Cardano emphasizes peer-reviewed research and formal verification in its protocol design—setting it apart from more agile but less rigorous blockchains.
Despite criticism about slow progress, Cardano ranks as one of the top ten cryptocurrencies by market cap. More importantly, it has quietly built a growing ecosystem, particularly in decentralized finance (DeFi). After lagging behind rivals for years, Cardano saw a dramatic increase in total value locked (TVL) across its DeFi platforms in 2024–2025—an indicator of rising user trust and engagement.
Cardano’s smart contract capabilities now allow developers to build complex dApps comparable to those on Ethereum. With a much lower valuation—around $21 billion compared to Ethereum’s $276 billion—there’s room for substantial upside if adoption accelerates.

Notably, while Bitcoin surged 160% in 2025, Cardano kept pace with a 150% gain—proving it’s far from stagnant. For investors seeking undervalued projects with solid foundations, Cardano represents a compelling opportunity.
Buy, Sell, or Hold?
While Polygon, XRP, and Cardano are among the most prominent cryptos under $1, none should be considered low-risk investments. Each faces distinct challenges:
- Polygon must innovate quickly amid fierce Layer 2 competition.
- XRP remains entangled in regulatory limbo.
- Cardano needs broader developer adoption to close the gap with Ethereum.
Given these factors, none should form the core of a conservative investment portfolio. However, for those with a higher risk tolerance, small allocations may be justified based on long-term potential.
Among the three, Cardano stands out as the most bullish case. Its combination of strong fundamentals, increasing DeFi activity, and relative undervaluation makes it a candidate for outsized returns if momentum continues.
Frequently Asked Questions (FAQ)
Q: Can any crypto under $1 become a top performer?
A: Absolutely. Price per coin doesn’t reflect value or potential. Many top cryptos started under $1. Market cap and utility matter more than unit price.
Q: Is XRP safe to invest in during the SEC lawsuit?
A: It carries significant legal risk. Only consider it if you understand the potential outcomes and can tolerate volatility.
Q: Why is Cardano considered “boring” by some?
A: Because it prioritizes academic rigor and slow, secure development over rapid feature releases or marketing hype.
Q: Does low price mean a crypto is cheap?
A: Not necessarily. A low price per coin doesn’t mean it’s undervalued—always check market capitalization and token supply.
Q: How important is Ethereum’s performance to Polygon?
A: Extremely. Polygon’s success depends on Ethereum remaining the dominant Layer 1 chain for dApps and DeFi.
Q: Could Cardano ever surpass Ethereum?
A: Unlikely in the short term, but it can capture significant market share by offering similar capabilities at lower cost and higher efficiency.
