CoinShares has withdrawn its U.S. spot ETF filings for XRP, Solana, and Litecoin, citing unmet operational requirements from the SEC. The European digital asset manager highlighted regulatory and market challenges as key factors in its decision. CoinShares plans to shift its focus towards hybrid ETFs and Nasdaq listing plans, halting its staking ETF applications for these cryptocurrencies. This move reflects the broader industry's adaptation to increased SEC scrutiny.
