币界网报道：Ouinex, a crypto trading platform, is beta testing a new feature allowing users to trade stocks directly using cryptocurrency as collateral. The France-based exchange aims to bridge traditional and digital asset markets by enabling cross-asset trading without requiring fiat conversions. CEO Ilies Larbi stated this innovation addresses traders' need for seamless asset transitions while maintaining crypto holdings. The feature currently supports major cryptocurrencies like Bitcoin and Ethereum as collateral for trading European and U.S. stocks. Ouinex plans to expand support to more assets and regions following the beta phase. This development comes as crypto platforms increasingly explore integrations with traditional finance, offering users more flexibility in asset management across markets. The exchange emphasizes security measures including segregated collateral accounts and real-time risk monitoring.
