The world of cryptocurrency is expanding at a breakneck pace. In just the first few months of 2025, over 100 initial coin offerings (ICOs) have already hit the market — a staggering 460% increase compared to the same period last year. Since April of the previous year, when Bitcoin’s price began its dramatic climb, more than 320 new cryptocurrencies have launched, capturing global attention and investor interest.
With so many digital assets flooding the market, a critical question emerges: Which cryptocurrencies are not just popular, but actually stable and credible enough to consider for long-term investment? Amid volatile price swings and speculative hype, investors are searching for reliable signals of legitimacy and financial health.
Enter Weiss Ratings, a well-established financial rating agency known for evaluating stocks, mutual funds, and insurance companies. In a move that has sparked both interest and debate, Weiss has extended its expertise into the crypto space by launching one of the first comprehensive rating systems for digital currencies.
Understanding the Weiss Cryptocurrency Rating System
Weiss Ratings does not claim to predict short-term price movements or guarantee safety like a traditional AAA corporate bond. Instead, it evaluates the overall risk-reward profile of 79 major cryptocurrencies using a transparent, letter-grade system ranging from A (excellent) to E (very weak).
The firm assesses each cryptocurrency across four key indexes:
- Risk: Measures price volatility and susceptibility to sharp declines.
- Reward: Analyzes historical price performance, both absolute and relative.
- Technology: Evaluates blockchain innovation, security features, and scalability.
- Fundamentals: Considers transaction speed, developer activity, community support, and real-world adoption.
These metrics are combined to produce an overall grade that reflects a crypto asset’s balance between potential returns and inherent risks.
“Many cryptocurrencies are murky, overhyped, and vulnerable to crashes. The market desperately needs the clarity that only robust, impartial ratings can provide,” says Martin Weiss, founder of Weiss Ratings.
Despite high expectations, no cryptocurrency earned an 'A' or even 'A-minus' in the latest assessment. Weiss emphasizes that “at this early stage in their evolution, there is no such thing as a 'safe' cryptocurrency.” However, several digital assets have achieved a B-minus, placing them in the “good” tier — the highest category currently attainable.
The 5 Highest-Rated Cryptocurrencies (B-Minus Tier)
While no crypto has reached top-tier status yet, five stand out for their relative strength and resilience:
1. Bitcoin (BTC)
As the original cryptocurrency, Bitcoin remains the gold standard of digital assets. With a market capitalization exceeding $137 billion, it leads the pack in terms of recognition, liquidity, and network security. Its B-minus rating reflects strong fundamentals — particularly decentralization and protocol stability — though its scalability limitations keep it from scoring higher.

2. Ripple (XRP)
Valued at around $23 billion, Ripple ranks as the third-largest cryptocurrency. Unlike many others, XRP is designed specifically for fast, low-cost international money transfers. It has gained traction among banks and financial institutions, giving it solid real-world utility — a factor Weiss weighs heavily in its fundamentals index.
3. EOS
With a market cap near $5 billion, EOS is recognized for its high-speed blockchain capable of processing thousands of transactions per second. It aims to support large-scale decentralized applications (dApps), making it attractive for developers. While its technology scores well, concerns about governance and centralization slightly dampen its overall score.
4. NEO
Often dubbed “China’s Ethereum,” NEO sits at number nine in market value with nearly $4 billion in circulation. It supports smart contracts and digital identity verification within a regulated framework — appealing in regions prioritizing compliance. Its strong technological foundation contributes to its favorable rating.
5. Steem
Though significantly smaller — with only about $450 million in market value — Steem earns its place due to robust community engagement and consistent transaction volume. Built around social media platforms like Steemit, it demonstrates niche adoption and active user participation, which Weiss considers positive indicators.
How Do Other Major Cryptocurrencies Compare?
Most of the top 10 cryptocurrencies fall into the "fair" category with a C+ rating. This includes:
- Ethereum (ETH) – The leading platform for decentralized applications and smart contracts.
- Litecoin (LTC) – Known for faster block generation and lower fees than Bitcoin.
- Cardano (ADA) – Focused on peer-reviewed research and sustainable development.
- Stellar (XLM) – Targets cross-border payments with nonprofit partnerships.
- IOTA (MIOTA) – Designed for Internet of Things (IoT) microtransactions.
While these projects show promise, they face challenges in scalability, adoption, or volatility that prevent higher grades.
Notably, Bitcoin Cash (BCH) receives a D+, classifying it as “weak” due to declining developer interest, reduced transaction volume, and ongoing controversy over its value proposition post-fork.
Cryptocurrencies at the Bottom of the List
At the lower end of the spectrum are largely unknown or defunct projects such as:
- Auroracoin (E)
- Comet (E-)
- Electroneum (E+)
- PotCoin (D-)
- SaluS (E)
Many of these have negligible trading volume and lack active development. Most haven’t maintained a price above $10 per coin in over a year, suggesting minimal investor impact.
Controversy Surrounding the Weiss Ratings
No rating system is immune to criticism — especially in the fiercely passionate crypto community. When Weiss initially gave Bitcoin a C+, many investors reacted strongly, arguing that the methodology undervalued core principles like decentralization and security.
Ari Paul, CIO of BlockTower Capital, noted:
“Their rating of Bitcoin suggests a misunderstanding of the core value proposition of cryptocurrency… they seem to overvalue transaction capacity, and undervalue protocol stability, security, and decentralization.”
Others questioned whether a traditional financial ratings firm could truly grasp the nuances of blockchain innovation.
However, Weiss defends its approach as data-driven and independent. Whether these ratings gain long-term credibility will ultimately depend on how accurately they correlate with future market performance.
Frequently Asked Questions (FAQ)
Q: Are B-minus rated cryptos safe to invest in?
A: No cryptocurrency is completely safe. A B-minus indicates relatively lower risk compared to others, but all digital assets carry significant volatility and regulatory uncertainty.
Q: Why didn’t any crypto get an 'A' rating?
A: According to Weiss Ratings, the ecosystem is still too immature. Issues like scalability, regulation, and security vulnerabilities prevent any asset from achieving top-tier status.
Q: Is Bitcoin really safer than other cryptos?
A: By metrics like network size, hash rate, and global adoption, yes — Bitcoin is generally considered more resilient than most altcoins.
Q: Should I rely solely on Weiss Ratings for investment decisions?
A: No. These ratings should be one tool among many. Always conduct independent research and consider your risk tolerance before investing.
Q: What makes a cryptocurrency “fundamentally strong”?
A: Strong fundamentals include active development, real-world use cases, fast transaction speeds, scalability solutions, and broad community or institutional support.

Final Thoughts
While the promise of high returns draws many to cryptocurrency investing, understanding risk is equally important. Weiss Ratings offers a structured way to compare digital assets beyond price charts and hype cycles.
The five B-minus cryptocurrencies — Bitcoin, Ripple, EOS, NEO, and Steem — represent some of the most balanced options available based on technology, adoption, and stability. That said, even these come with caveats.
As the market matures, tools like independent ratings will become increasingly valuable for filtering signal from noise.
Whether you're a seasoned trader or new to crypto, staying informed is your best defense against speculation and loss.
