Row by row
The edge on each row is marked. Rows that describe rather than rank — jurisdiction, currencies, market categories — say “no edge” instead of picking a side.

| Fee conditions & evidence | "0.30% of a fill's value, paid only by the taker"; makers pay nothing; no ParamX deposit, withdrawal or gas fees (docs). Review evidence · Official fee source | Taker fee = shares × category rate × price × (1 − price). For 100 crypto shares at $0.50 with rate 0.07, the fee is $1.75 on a $50 purchase: 3.5% of purchase cost, not 1.75%. Rounding and any rebates must be considered separately.
