Bit.com calculates the total USD collateral of a unified margin (UM) account based on currency haircut ratios*. The higher the haircut ratio of a currency, the lower the conversion rate of that currency as collateral.
* Which are measured against USD
Based on the risk profile of each currency, bit.com classifies them into the following tiers.
For example, if a user holds 10 BCH in the UM account, haircut ratio is 5% and currency index is 500, the calculated USD collateral in the account would be 10*500*(1 - 5%) = 4750 USD.
