US regulators just greenlit something big—crypto can now be used as collateral in derivatives trading. The CFTC rolled out a pilot initiative that lets market participants post digital assets as margin for futures and options positions. This marks a notable shift in how traditional finance views crypto legitimacy. For traders juggling both worlds, it means more capital efficiency. No longer stuck choosing between holding coins or accessing leverage—now you can do both. The program's still in testing phase, so expect strict compliance requirements and limited participants initially. But if it works? Could reshape how institutional players approach crypto exposure in regulated markets.
