In the fast-evolving world of cryptocurrency, trust and transparency are paramount. Yet, one of the most commonly used metrics for evaluating crypto exchanges—trading volume—has come under increasing scrutiny. As users seek more reliable ways to assess platform legitimacy and performance, blockchain researchers are rethinking how exchanges should be ranked.
Traditionally, “reported volume” has been the default benchmark. Platforms like CoinMarketCap display this figure prominently, leading many investors and traders to use it as a proxy for exchange quality. However, the gap between reported and adjusted trading volumes on such sites reveals a troubling inconsistency. For example, adjusted data often shows that up to 90% of reported volume may be inflated or fabricated—a phenomenon driven by practices like wash trading and transaction mining.

This growing skepticism has prompted innovative platforms like ViewBase, a crypto-focused market insights and community hub, to propose alternative ranking methodologies grounded in verifiable on-chain data. Instead of relying solely on self-reported volume, these new models assess exchanges based on actual digital asset holdings and economic activity within their ecosystems.
Beyond Trading Volume: A New Framework for Trust
Ranking exchanges purely by trading volume—especially unverified figures—is becoming increasingly obsolete. The rise of Initial Exchange Offerings (IEOs) and incentive-driven trading has amplified distortions. In transaction mining schemes, users earn tokens simply for placing trades, artificially inflating volume without reflecting genuine market demand.
To counter this, ViewBase introduced a data-driven framework that evaluates exchanges using three core blockchain-based metrics:
- Ethereum (ETH) balances held
- Total value of ERC-20 tokens deposited
- Combined value of ETH and all ERC-20 tokens
These indicators offer a more objective, transparent view of an exchange’s real economic footprint.
1. Ethereum Balances: Who Holds the Most ETH?
One of the clearest signs of user trust is how much cryptocurrency an exchange holds in its wallets. By analyzing on-chain data, ViewBase found that Kraken leads the pack with nearly 3 million ETH in reserves—far more than any other exchange.
Interestingly, despite holding the largest ETH balance, Kraken ranks only No. 98 in ETH trading volume according to CoinMarketCap, accounting for less than 1% of Ethereum’s daily $7.4 billion trade volume. This disconnect suggests that high holdings don’t necessarily correlate with high trading activity.
Binance follows closely behind Kraken in ETH holdings. Its ETH/USDT market ranks 32nd, capturing almost 1% of daily Ethereum volume. While not the top holder, Binance demonstrates stronger turnover relative to its reserves—indicating a more active trading environment.
2. Value of ERC-20 Tokens: Measuring Ecosystem Depth
The second metric focuses on the total value of ERC-20 tokens held across exchanges. This shifts the landscape significantly, as platforms that support a wide range of altcoins gain prominence.
Here, Binance surges ahead, thanks to its vast array of listed tokens—from established projects like OmiseGo to newer IEOs such as Fetch.ai and Celer Network. Since most ICOs and IEOs issue tokens on Ethereum, the aggregate value of deposited ERC-20s can serve as a proxy for exchange adoption and community engagement.
ViewBase notes:
“A vast majority of Initial Coin Offering (ICO) tokens are issued on the Ethereum blockchain… Hence it is reasonable to expect the valuation of ERC20 tokens deposited on an exchange to be reasonably proportional to its reported trading volumes.”
Huobi follows Binance in this category, reflecting its strong presence in the altcoin market. Meanwhile, Kraken drops significantly due to its focus on fiat gateways and major-cap cryptocurrencies rather than niche or newly launched tokens.
3. Combined Value: The Ultimate On-Chain Scorecard
The final and most comprehensive metric combines both ETH and all ERC-20 token values held by each exchange. This holistic approach reveals Binance’s dominant position—not just through volume, but through sheer asset depth.
Binance’s lead is further amplified by Binance Coin (BNB), one of the largest cryptocurrencies by market cap. As BNB is an ERC-20 token (prior to its migration to BNB Chain), a significant portion of its circulating supply is stored directly on Binance, inflating the exchange’s total token valuation.
Despite falling in the ERC-20 rankings, Kraken re-enters the top five when ETH holdings are factored back in—demonstrating its enduring role as a trusted custodian for long-term investors.

Why On-Chain Data Matters
The key takeaway from this research is clear: trading volume alone is no longer sufficient for evaluating an exchange’s true significance. While liquidity remains important—especially for day traders and institutional players—it doesn’t reflect underlying trust, security, or ecosystem strength.
On-chain data provides a tamper-resistant window into actual user behavior. When millions of dollars worth of crypto are deposited into an exchange, it signals confidence—even if those assets aren’t actively traded.
However, this concentration also raises concerns. The fact that a handful of platforms hold such vast amounts of digital assets underscores the risks of centralized custody. As the old crypto adage goes: “Not your keys, not your crypto.” The more assets users leave on exchanges, the more vulnerable they become to hacks or operational failures.
Frequently Asked Questions (FAQ)
Q: Why is reported trading volume unreliable?
A: Many exchanges inflate their volume through wash trading or reward users for making fake trades (transaction mining). This creates misleading impressions of liquidity and popularity.
Q: How does on-chain data improve exchange rankings?
A: On-chain analysis tracks real wallet balances and transactions, offering verifiable insights into asset holdings and user activity—free from manipulation.
Q: Is holding large amounts of crypto a sign of strength or risk?
A: It’s both. Large holdings indicate user trust, but they also represent single points of failure. If compromised, these reserves could lead to massive losses.
Q: Can decentralized exchanges (DEXs) be ranked the same way?
A: Yes, though DEXs typically hold fewer user funds since traders retain control of their wallets. Rankings would need to emphasize trade flow and smart contract activity instead.
Q: What should investors look for when choosing an exchange?
A: Consider verified volume, security history, supported assets, withdrawal speeds, and increasingly, on-chain footprint—all alongside personal needs like fiat access or staking options.

Final Thoughts
As the crypto industry matures, so must its evaluation tools. Relying on flawed metrics like unadjusted trading volume undermines market integrity and misleads investors. By leveraging transparent, blockchain-based data—such as actual token holdings—researchers and platforms like ViewBase are paving the way for more honest, objective exchange rankings.
For users, this means better tools to distinguish signal from noise. For the industry, it represents a step toward greater accountability—and ultimately, wider adoption.
The future of exchange evaluation isn’t about who trades the most. It’s about who holds the most trust.
