The CPA-versus-revshare argument has no general answer. It has one number as an answer: how long your player sticks around.
When CPA wins
When the traffic is one-shot: the person arrives, deposits, plays and leaves. A share of their revenue is then negligible while the one-off payment is not. At 1win Partners the CPA ceiling is $250 per player.
CPA has a second advantage: money arrives fast and predictably. For anyone funding traffic out of pocket, turnover beats ceiling.
When revshare wins
When the audience is yours, warm and returning. Revshare from 50% on a player who stays six months beats any single payment — but it beats it later, not immediately.
This is the model for people with their own channel or chat, where nobody vanishes after the first touch. Working out the horizon: player lifetime value.
How to settle it yourself
Take your first cohort and see how many made a second deposit, and a third. Almost nobody? Your traffic is one-shot and there is nothing to debate. A noticeable share returning? Run the revshare numbers.
Doing this on somebody else's averages is pointless: their audience is not yours.
The mixed option
Different sources, different models. Cold outreach usually yields one-shot players, your own channel yields returning ones. Nothing stops you running them through separate links on separate terms.
