Weiss Ratings, an independent U.S. ratings agency, has issued a detailed defense of its decision to assign Bitcoin a C+, arguing that the grade reflects measurable weaknesses in market behavior and network performance rather than hostility toward cryptocurrency. The explanation came after the firm faced a fierce backlash from crypto supporters following the release of its letter-grade rankings.
According to the report, criticism did not remain limited to social media. Weiss said it was hit with insults from prominent voices in the crypto community, and its website was even temporarily disrupted by a cyberattack. In response, the agency published a 14-page report laying out the framework and data behind Bitcoin’s score.
Why Weiss Says Bitcoin Does Not Merit an A
Martin D. Weiss, founder of Weiss Ratings, said the agency’s top grades are reserved for assets that do not experience repeated severe crashes. By that standard, he argued, no cryptocurrency currently qualifies. In his view, many developers objected to the grade because they believe ratings should focus mainly on technical merit and real-world success, while investors also need a system that captures instability, downside risk, and actual market performance.
That distinction is central to the firm’s defense. Weiss says its cryptocurrency model was designed to address both audiences: investors concerned with preservation of capital and return potential, and developers focused on adoption, architecture, and execution.
The Rating Framework Behind the C+
The agency said its model combines several sub-models. Two of them—Risk and Reward—are adapted from its approach to stocks and exchange-traded funds. Two others—Fundamentals and Technology—were developed specifically for cryptocurrencies.
Under Risk and Reward, Weiss argued that Bitcoin investors had recently earned less than many altcoin investors while still facing extreme volatility. In other words, from the agency’s perspective, Bitcoin did not deliver superior upside relative to the level of risk investors were taking on.
Under Fundamentals, the agency gave Bitcoin credit for its adoption and security. Even so, it said those strengths were offset by meaningful constraints. The report cited network congestion, throughput of only about four transactions per second, and transaction fees of roughly $10 per transfer as notable weaknesses. It also pointed to mining concentration, saying the top five miners controlled about 70% of total hashpower, a factor it viewed negatively.
Under Technology, Weiss said Bitcoin lacks a governance structure capable of enabling prompt upgrades. In a rapidly evolving digital asset market, the report argued, that leaves the network at risk of falling behind more adaptable competitors.
Answering the Volatility Criticism
One of the main complaints aimed at Weiss was that its ratings place too much weight on price swings. The firm rejected that accusation. It argued that the model does not exaggerate volatility but instead recognizes a difficult truth about the cryptocurrency market: extreme swings are a core feature of the sector and matter greatly for investors.
For Weiss, this is not a philosophical issue but a practical one. A rating intended for investors cannot ignore drawdowns, instability, and the relationship between return and risk. In that sense, the agency appears to be drawing a clear line between enthusiasm for Bitcoin’s long-term promise and a rating methodology meant to assess present conditions.
Could Bitcoin’s Rating Improve?
Weiss also stressed that its ratings are dynamic rather than fixed. The agency said Bitcoin could receive an upgrade if market prices become more stable or if speed and scaling improvements are implemented successfully. That caveat is important because it suggests the C+ is not being framed as a permanent verdict on Bitcoin, but as a snapshot based on current performance across several metrics.
The report therefore presents the Bitcoin grade as conditional: strong in some areas, limited in others, and ultimately held back by unresolved issues around volatility, throughput, cost, mining concentration, and upgrade coordination.
A Broader Debate About How Crypto Should Be Rated
The dispute highlights a larger tension in crypto analysis. Supporters often want the leading digital assets judged by decentralization, innovation, censorship resistance, security, and ecosystem growth. Traditional rating logic, however, tends to emphasize measurable risk, reliability, and consistency—especially from the standpoint of investors who may be less interested in ideology than in portfolio outcomes.
Weiss is effectively arguing that Bitcoin’s reputation as the market leader does not exempt it from scrutiny on costs, scalability, or governance. At the same time, the agency acknowledges Bitcoin’s strengths, particularly in security and adoption, showing that the C+ grade was not presented as a dismissal of the asset altogether.
Whether market participants agree with the methodology is a separate question. But the release of the 14-page explanation makes clear that Weiss intended to defend the score on analytical grounds, not sentiment. The agency’s position is that Bitcoin’s current profile is mixed: important, influential, and widely adopted, yet still constrained by structural issues that matter in a formal ratings framework.
As debate over crypto ratings continues, the episode underscores how difficult it remains to evaluate digital assets using a model that satisfies both investors and builders. For now, Weiss is standing by its view that Bitcoin’s C+ is a fair reflection of the asset’s balance of strengths and weaknesses at this stage of the market.
