XRP is under scrutiny as crypto analyst Iso Ledger questions the sustainable demand for the asset within the XRP Ledger (XRPL) economy. In a recent post, Iso Ledger argued that if XRPL were globally adopted, XRP might primarily serve as a gas token, raising concerns about its long-term demand. He suggested that XRP's value lies in its role as a liquidity bridge between currencies lacking direct trading pairs, facilitating transactions like those between a Japanese pension fund and a Brazilian supplier. Iso Ledger highlighted potential challenges if liquidity deepens across XRPL, potentially sidelining XRP in favor of direct settlement paths. He proposed that the upcoming XLS-66D lending protocol could address these issues by locking up XRP supply, potentially boosting its price and reinforcing its role as a settlement asset. He questioned why significant investments and developments, such as XRP ETFs and Goldman Sachs' $152 million investment, would occur if XRP were merely a gas token, suggesting the market may be underestimating its evolving role.
