Gemini has expanded its collateral options for derivatives trading, now accepting XRP, Shiba Inu (SHIB), Dogecoin (DOGE), Solana (SOL), and Bitcoin Cash (BCH) alongside Bitcoin (BTC). This update, effective early 2024, allows traders to leverage a broader range of digital assets, potentially enhancing their margin asset value. However, Gemini will liquidate collateral if trades incur losses, highlighting the importance of risk management given the volatile nature of cryptocurrencies like XRP and SHIB.
