How we work
I
Nobody can promise profit on a prediction market, so we don't. We explain the mechanics and the risks, and you make the calls.
II
Fees come from the official docs, cases from named publications and statistics from published studies. Each one is linked.
III
Links to Polymarket on this site are referral links. We may receive a share of Polymarket's trading fees, and your fees stay the same. That's how the course stays free.
IV
We teach position sizing and reading the rules before any strategy, because a blown-up account can't use one.
