The new dynamic fee structure peaks near 50% probability, with Crypto markets charged up to 1.80% and Finance, Politics, and Tech markets at approximately 1.00%.

Fees will fund Maker Rebate incentives and are priced in USDC, with buy orders charged in shares and sell orders in USDC. Traders monitoring altcoins may need to adjust their strategies as the Fear & Greed Index responds to this change.
