Crypto analyst Dark Defender has claimed that XRP stands out as the only real asset among the collateral choices accepted by Ripple Prime, a financial platform by Ripple that caters to institutional clients. While Ripple Prime accepts a variety of assets as collateral, including U.S. Treasuries, gold, and a suite of stablecoins such as RLUSD, with RLEUR, RLJPY, and RLGBP planned for future support, Dark Defender argues that these options differ substantially in nature.
