Customers have the option to trade perpetuals using leverage. This means that the capital required to trade a perpetual is significantly less than the total notional value of the underlying asset. However, this also means that the customer may lose all of this funding capital should the market move against them. 

In order to maintain the integrity of the derivatives platform, users of perpetuals are subject to an auto-liquidation feature. This means their positions will be automatically closed once the risk of the position is too high compared to the funds available to support it. Cryptocurrencies are volatile and leverage will amplify this volatility, meaning losses can be quickly accumulated. 

Perpetuals are specific to a platform and cannot be moved or traded on another exchange - positions have to be closed on the platform.
