Volume Is Not Liquidity
High traded volume is often read as a sign of a liquid market. It is a weak proxy at best — and at times an actively misleading one.
Volume rankings are the most visible statistic in crypto market data. It is natural to assume that the venue or asset with the most volume is the easiest to trade. But volume is a record of past transactions. Liquidity is about the present: how much can be traded, how quickly, and at what cost.
Where the two diverge
- During sell-offs, volume surges while spreads widen and depth collapses.
- High-frequency trading between a small number of participants can generate large volume with little resting depth.
- Fee rebates and incentive programs can encourage trading that exists mainly to earn the incentive.
- Reported volume on some platforms has historically included activity that did not reflect genuine exchange between independent parties.

Better measures
Liquidity is better described by quoted and effective spreads, depth within basis-point bands of the mid, estimated impact for relevant order sizes, and resilience after large trades. Volume remains useful context — especially volume relative to depth — but it should never stand in for them.
