Sizing a Two-Exchange Book: Bitget vs BitMart Funding and Margin Headroom

The same funding print does not imply the same safe size. Bitget and BitMart can differ in margin parameters, liquidation proximity, and how basis moves your short leg — so sizing must be venue-aware.

Bitget is a common venue in perpetual rotations; fee promos and tiers change — re-check before scaling.

BitMart can show interesting dispersion on some alts; treat operational checks as mandatory, not optional.

Split collateral vs concentrated collateral

Each layout changes transfer needs and stress behavior. There is no universal winner — only what matches your ops tolerance.

Use monitoring as a risk tool

Portfolio Management and Alerts are how you keep two-account sizing from drifting into denial.

Depth still caps size

Depth checks belong in Orderbook Snapshot — especially when a free arbitrage screener row looks "too good" on a thin alt.

FAQ

Why do the same symbols show different funding on Bitget and BitMart?

Index components, caps, participant mix, and cadence rules differ. That is why cryptocurrency price difference thinking is misleading: you are comparing two related but not identical perpetual products.

Takeaway

Bitget vs BitMart comparisons should include sizing discipline — otherwise funding is just a number.
