Up until recently, traders were still often facing some significant risks, such as: Liquidity issues: only certain coins and exchanged listed strikes and expiries are quoted on exchanges.

Counterparty risk: options are contracts between two parties, so they come at a risk that the trading counterparty won't deliver.
