Digital assets and cryptocurrency futures or derivatives may experience significant price volatility, and the initial margin for cryptocurrency futures or derivatives may be set as a percentage of the value of a particular contract, which means that margin requirements for long positions can increase if the price of the contract rises. In addition, some FCMs may pose restrictions on customer trading activity in cryptocurrency futures or derivatives, such as requiring additional margin, imposing position limits, prohibiting naked short selling or prohibiting give-up transactions. The rules of certain designated contract markets impose trading halts that may restrict a market participant’s ability to exit a position during a period of high volatility.
