The cryptocurrency market continues to mature, with liquidity emerging as a critical factor for traders, investors, and institutions alike. This comprehensive analysis leverages objective order book depth data to evaluate the liquidity performance of 12 major centralized exchanges (CEX) over a six-month period—from January to June 2025. Using the proprietary LTP Liquidity Score, we assess real market depth across Bitcoin (BTC) and Ethereum (ETH) trading pairs, offering data-driven insights into platform stability, asset-specific trends, and overall market health.
Understanding Liquidity in Financial Markets
What Is Liquidity?
In finance, liquidity refers to how quickly an asset can be converted into cash without significantly affecting its market price. Two core principles define liquidity:
- Price Impact: The smaller the price movement caused by a trade, the higher the asset’s liquidity.
- Ease of Conversion: Assets that can be quickly bought or sold with minimal friction are considered more liquid.
👉 Discover how real-time liquidity data can improve your trading strategy.
For example:
- If a $100,000 purchase of Asset A moves its price by 1%, while the same amount spent on Asset B causes a 2% shift, Asset A is more liquid.
- Similarly, gold is more liquid than real estate because it can be sold faster and with less price disruption.
Liquidity in Centralized Crypto Exchanges (CEX)
Centralized exchanges use order books—live lists of buy and sell orders—to match trades. The deeper the order book (i.e., the more buy/sell orders at various price levels), the better the liquidity.
For instance, a BTC/USDT order book might show:
- Buyers willing to purchase 50 BTC within 0.1% below the current price.
- Sellers offering 72 BTC within 0.1% above.
This depth allows traders to execute large orders with minimal slippage. By analyzing these levels across exchanges, we gain insight into which platforms offer superior execution quality.
How Decentralized Exchange (DEX) Liquidity Works
Unlike CEXs, decentralized exchanges like Uniswap rely on Automated Market Makers (AMMs) and liquidity pools instead of order books. These pools are funded by users (known as Liquidity Providers or LPs) who deposit pairs of tokens into smart contracts.
The most common model uses the constant product formula: x * y = k
This ensures that price changes are algorithmically determined based on trade size and available reserves.
Liquidity on DEXs is often measured by Total Value Locked (TVL)—the total value of assets in a pool. Higher TVL typically means lower slippage and better trading conditions.
Introducing the LTP Liquidity Score
Why Traditional Volume Metrics Fall Short
Trading volume is easily manipulated through wash trading, making it an unreliable indicator of true market depth. To address this, LTP developed a transparent, data-backed methodology focused solely on real-time order book depth.
The LTP Liquidity Score evaluates exchanges based on actual market-making activity, offering a clearer picture of where traders can execute efficiently.
How the LTP Liquidity Score Is Calculated
- Data Collection: Gather order book snapshots from major exchanges for key trading pairs (e.g., BTC/USDT, ETH/USD).
- Depth Analysis: Measure total buy/sell volume within five price ranges: 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% from the current market price.
- Relative Scoring: Assign scores based on depth comparison across exchanges at each level.
- Weighted Aggregation: Combine scores using volume-weighted averages—pairs with higher trading volumes influence the final score more.
- Multi-Currency Evaluation: Repeat for multiple base assets and aggregate results per exchange.
This method eliminates subjective bias and highlights platforms with genuine market depth.
Key Cryptocurrencies and Trading Pairs Analyzed
To ensure accuracy and relevance:
- We analyzed over 13 major trading pairs across BTC and ETH.
- Only pairs accounting for over 70% of total exchange volume were included.
- Direct comparisons were made between equivalent pairs (e.g., BTC/USDT vs BTC/USD).
This ensures consistency while reflecting real-world trading behavior.
Top Crypto Exchanges by Liquidity: Mid-Year 2025 Rankings
Leading Platforms Maintain Stability
Based on average LTP Liquidity Scores from January to June 2025:

Binance maintains its position as the most liquid exchange, especially for small-to-medium trades near the mid-price. Kraken follows closely, showing strong performance beyond narrow spreads.
The top four platforms demonstrate consistent rankings throughout the observation period—indicating robust infrastructure and sustained user trust.
Emerging Players Show Growth Momentum
- Gate.io rose from 8th to 7th place with an average score of 71.87, showing significant improvement post-March.
- KuCoin also displayed upward momentum, though still lagging behind the leaders.
- Bitfinex exhibited high volatility in its liquidity score—peaking sharply but dropping unpredictably.
Meanwhile, Phemex, Huobi, Crypto.com, and Coinex showed little change, suggesting stagnant growth in market-making activity.

Asset-Specific Liquidity Insights
Bitcoin (BTC) Market Depth Analysis
Across all exchanges:
- At 0.1% price deviation, average BTC depth remains under $50 million.
- At 0.3%, it reaches approximately $100 million.
- Beyond 0.4%, gains plateau—indicating thinner order books at wider spreads.
BTC Liquidity by Exchange
- Binance dominates near the mid-price, offering the tightest spreads—ideal for retail traders.
- At wider ranges (>0.3%), Kraken and OKX often surpass Binance, thanks to aggressive market-making and fee incentives (e.g., Kraken’s zero-fee BTC trading).
- During peak volatility in early March and early June, Kraken consistently held first place in broader depth categories.
Ethereum (ETH) Liquidity Trends
ETH liquidity is more volatile than BTC’s:
- Depth peaks between 0.3%–0.4%, exceeding $75 million.
- Buy/sell balance remains nearly 1:1, indicating balanced market sentiment.
- No significant gain beyond 0.5%, suggesting limited interest in deep out-of-range orders.
ETH Liquidity by Exchange
- While Binance leads overall, its score fluctuates by over 50% within short windows.
- On June 11th, Binance’s ETH liquidity dipped below 75 during early morning hours before recovering.
- OKX and Bybit are closing the gap—especially within 0.1% range, where their scores match Binance almost exactly.
This suggests rising competition in ETH markets, driven by improved market-making strategies.
The LTP Liquidity Index (LLI): Gauging Market Health
What Is the LLI?
The LTP Liquidity Index (LLI) measures overall crypto market liquidity using weighted order book depth from Binance, Coinbase, and Kraken for both BTC and ETH.
It serves as a macroeconomic barometer:
- Rising LLI = increasing confidence and capital inflow.
- Falling LLI = potential risk-off behavior or reduced participation.
How LLI Is Calculated
- Collect hourly order book depth across five price tiers (0.1%–0.5%) for BTC and ETH.
Apply tiered weights:
- 0.1% → 30%
- 0.2% → 25%
- 0.3% → 20%
- 0.4% → 15%
- 0.5% → 10%
- Compute daily weighted depth; normalize against baseline (Jan 1 = 1,000).
- Combine BTC (75% weight) and ETH (25% weight) indices into final LLI.
Future versions will include additional assets based on market cap and trading volume.
Six-Month LLI Performance (Jan–Jun 2025)
- LLI rose from 1,000 to 1,748, reflecting a broad improvement in market depth.
Two major spikes occurred:
- March: Tied to BTC breaking previous all-time highs.
- Early June: Coincided with renewed institutional buying.
- BTC-driven peaks reached nearly 4,000 points, signaling intense short-term liquidity surges.
- ETH saw only one major peak (mid-March); three sharp drops occurred—after ETF approval news and during macro sell-offs.
These patterns confirm that liquidity often leads price action—making LLI a valuable predictive tool.
