Volume records trading activity; it does not show how much is available at current prices, how wide the spread is, or how far your order may move the market. To assess a trade, look at the specific venue and pair, then compare volume with spread, executable depth and estimated slippage for your intended order size.
What trading volume tells you—and what it leaves out
Trading volume measures completed transactions over a defined period. It can help show how active a market has been, but it is not a direct measure of the cost or ease of your next trade. A large daily volume figure may coexist with a wide spread or thin order book at the time you want to trade.
S&P Global treats volume, bid-ask spread, market depth and slippage as distinct liquidity measures. That distinction matters: activity recorded over an interval is not the same as executable orders available now, and neither alone guarantees a particular execution price.
| Measure | What it tells you | What to check |
|---|---|---|
| Volume | Transactions recorded over a chosen interval. | The venue and pairs included, the time period, and whether the figure is reported or adjusted. |
| Bid-ask spread | The difference between the lowest ask and highest bid. A narrower spread generally means a lower immediate quote cost. | Compare at approximately the same time. For markets at different price levels, compare the spread relative to the midpoint. |
| Market depth | Executable buy and sell interest within a stated distance of the midpoint. | Specify the price band and express amounts in a common currency. For example, 1% depth is the fiat-equivalent executable amount within 1% of the midpoint. |
| Slippage | The difference between a trade’s expected and actual outcome. | Check the assumed order size and execution method; slippage depends on both size and conditions. |
Why reported crypto volume can mislead
Artificial activity can make a market look busier
Wash trading involves self-trading or other transactions without meaningful economic purpose. It can create the appearance of active trading without establishing that independent buyers and sellers are available to execute your order.

In an Oct. 9, 2024 enforcement release, the U.S. Securities and Exchange Commission announced charges alleging that promoters and purported market makers used artificial volume and wash trading to create a false appearance of an active market for certain crypto assets. The release describes allegations; it should not be read as a finding that the defendants were liable. The practical lesson is to treat a volume figure as one piece of evidence, not proof of genuine, readily executable demand.
Market-wide totals depend on coverage and adjustment choices
A provider’s global total depends on which exchanges it includes and how it treats reported activity. Providers may publish reported volume, adjusted volume, or a figure whose adjustment status is unclear. They may also apply different filters, including to address suspected wash trading. As a result, two providers can report different totals because their coverage and methods differ, not necessarily because one has made a simple arithmetic error.

The 2025 paper Aggregate Confusion In Crypto Market Data, hosted by the SEC, found that the largest 10 exchanges accounted for almost 55% of reported global trading volume across the largest 250 crypto exchanges in its 2023 sample. The paper also estimated a power-law exponent of 2.99 for the distribution of exchange volumes and said this suggested infinite variance. These are findings about the paper’s data and analysis, not current exchange shares or universal constants. They illustrate why the exchanges included in an aggregate can materially affect the headline total.
Liquidity is specific to the venue and pair
The same token can have different spreads, depth and execution conditions on different exchanges and in different trading pairs. A coin-wide volume total therefore may not describe the market you will actually use. Compare the exact pair on the venue where you plan to place your order, using observations taken at roughly the same time.
S&P Global characterizes crypto liquidity as fragmented across platforms, with volume varying by exchange, asset and market. Its analysis covered Jan. 1, 2023, through Feb. 28, 2025, using Binance for centralized-exchange data and Uniswap V3 for decentralized-exchange data. Findings from that selected sample should not be treated as a description of every venue or asset.
One historical illustration in the report is BTC-KRW on Upbit during South Korea’s Dec. 3, 2024 political crisis, when the pair diverged sharply from the global BTC price for a period. That episode shows how local market conditions can differ from global indicators; it is not a statement about current prices.

How to assess a market before trading
- Choose the exact market. Identify the token pair and venue you would use. A global or coin-wide volume number is not a substitute for checking that market.
- Record the volume and its basis. Note the interval and observation time, which venues and pairs the figure covers, and whether it is reported or adjusted. If the provider does not disclose its methodology, treat that as uncertainty.
- Compare the spread at the same approximate time. Record the best bid and ask. When comparing markets at different price levels, use the spread relative to the midpoint rather than only the raw price difference.
- Check depth within a stated band. For example, compare executable amounts within ±1% of the midpoint and express them in the same currency. Thin depth means a larger order is more likely to move the price.
- Estimate slippage for your order size. Where an estimate is available, check what size and execution method it assumes. A result for a small order does not establish what a much larger order would cost.
- Repeat at other times or conditions. Order books change, particularly in volatile markets. A snapshot describes what was visible at that moment, not what will be available when your order reaches the market.
When comparing two venues that could both handle your trade, keep the pair, observation time, depth band and assumed order size consistent. Compare venue and pair coverage, volume methodology, quoted spread, depth at the same band and estimated slippage for the same order size. This makes the comparison more useful than ranking venues by headline daily volume alone.

For crypto-asset trading platforms covered by MiCA Article 76, the ESMA-hosted EU single rulebook requires advertised bid and ask prices and depth to be made public continuously during trading hours. It also requires transaction price, volume and time to be published as close to real time as technically possible. The rule calls for free, machine-readable access 15 minutes after publication and requires the information to remain published for at least two years.
Best Value
- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
Those requirements apply within MiCA’s scope; they are not a universal rule for every platform worldwide. Public market information can help you inspect a market, but it does not make a liquidity snapshot a promise of execution at a particular price.
