- Supply data: Token circulation, maximum supply, and total supply.
Market Capitalization Calculations
Market capitalization is displayed as:
CoinMarketCap only includes circulating supply defined as the number of coins accessible to the public and available for trading rather than total or max supply. This measure is vital for rankings but also prone to errors if project data is inaccurate or unaudited.

What Has CoinMarketCap Done to Improve Data Integrity?
CoinMarketCap has introduced several features and reforms aimed at improving data quality and transparency:
Liquidity Score CoinMarketCap
This metric measures the depth of order books and slippage to help users identify truly active trading environments.
Confidence Score CoinMarketCap
CMC flags suspicious market data with a confidence indicator, providing visual warnings for potentially unreliable figures.
Exchange Transparency Initiative
Exchanges are encouraged to submit proof of reserves, public API documentation, and detailed information about operations.
Independent Audits and Community Feedback
CoinMarketCap collaborates with third-party firms and invites community feedback to improve its data accuracy.
Liquidity Score and Confidence Score CoinMarketCap
Liquidity Score
Introduced in 2020, the Liquidity Score rates trading pairs based on:
- Market depth (how much can be bought/sold without price impact)
- Bid-ask spread percentage
- Size and frequency of real trades (not just reported volume)
- Time decay factors (more recent trades are weighted more)
This score (0 to 1000) is calculated per pair, giving users a better idea of actual trade execution reliability.
Confidence Score
A relatively new feature, Confidence Scores use real-time metrics to evaluate the trustworthiness of each data point:
- Green check: High confidence in pricing
- Yellow triangle: Moderate suspicion
- Red warning: Potential manipulation or data unreliability
Security and Data Integrity Practices
CMC’s backend infrastructure includes:
- CDNS (material delivery networks) to distribute load and prevent shutdown during instability spikes.
- Data facilities and replication layers to reduce delay and API of overload.
- API throttling and integrity checks for third-party exchanges.
- AI-based anomaly detection to spot sudden jumps in volume or price outside expected deviation bands.

Weaknesses and Criticisms
Fake Volume and Wash Trading CoinMarketCap
Several studies have shown that many Cryptocurrency exchanges reported trade volumes through strategy as a washforce – as well as with the purchase and sale of the same property to follow the activity.
While the CMC introduced the adjusted volume rice and flags suspected data, it is difficult to filter all fake inputs:
- Lack of standard reporting protocol in stock exchanges
- Limited regulatory inspection
- API HERFER
Circulating Supply Inaccuracy
Circular supply is important for calculating market capital. However, errors or old supply data can mistakenly present the real market to set up the real market.
- Some projects overport to promote ranking.
- Other people are unable to update burns, stacked or locked symbols.
- For new projects, manual intervention or team report may require, showing the risk of human error or conscious misunderstanding.
Delayed or Missing Listings
Many times, Coinmarketcap has slowed down to update data or list the new symbols-specially under high existing events, protocol fork or token migration. The delay can mislead users, especially when price deviations occur in stock exchanges.
Tips for Using CoinMarketCap Safely
To make the most of CoinMarketCap while avoiding pitfalls:
- Cross reference data with other platforms such as Koingko or Mesari.
- Do your own research before making investment decisions based on ranking.
- Be careful with new listed symbols with small volume or online appearance.
- Use trust points and liquidity assessments to assess data quality.
- Remember that the entry does not support the same.
