According to @KookCapitalLLC, SOL will be the next altcoin to set a new all-time high, following a rotation pattern where XRP made a new ATH and then retraced, and ETH did the same (source: @KookCapitalLLC on X, Sep 2, 2025). For traders evaluating this view, the prior SOL all-time high near $259 is a key breakout level to monitor for confirmation and risk management (source: CoinMarketCap historical price data for Solana).
