On March 25th, crypto market maker Wintermute launched WTI Crude Oil Contracts for Difference (CFDs). These are over-the-counter derivatives that allow traders to speculate on oil prices around the clock. Flexible execution methods and margin options enable traders to use fiat or crypto assets as collateral via chat, OTC electronic platforms, or APIs. Unlike the "one-size-fits-all" approach of exchange-listed standardized perpetual contracts, CFDs offer customized flexibility.
