A growth lead walks into a board meeting with one number on the slide. Cost per user acquisition, $38, down from $44 the quarter before. The room nods, and nobody asks what the denominator was.
Six weeks later, the close lands, and finance adds the airdrop allocation, the bonuses paid out, and the hours legal spent on the campaign creative. The same campaign now reads $190 per funded account. More cost went into the top of that fraction, fewer users came out of the bottom, and the campaign itself never changed.
The CAC definition everyone has copied from each other counts media and salaries, excludes every incentive, and traces back to nobody who has run a crypto exchange marketing campaign.
This Surgence Labs guide covers what the number measures, which channel and funnel-stage figures can be cited in 2026 and which cannot, and the incentive and compliance spend nobody publishes. Crypto CAC is a denominator problem before it is a spend problem, and getting that wrong turns every channel comparison into fiction.
Cost per user acquisition is the result of counting every cost line, attributing each to a channel, and dividing by funded accounts for exchanges and trading apps, token incentives included. It is a fully loaded cost per retained funded user, not a per-campaign cost per install. Count all of it, and channels become comparable. Count media alone, and you scale whichever hides the most cost. Arithmetic before accounting.
