According to @JSeyff, as highlighted by Eric Balchunas, traders should prepare for a potential Alt Coin ETF Summer with Solana positioned to lead upcoming spot ETF launches. J Seyff's morning note provides updated odds for all major spot ETFs, indicating heightened probability for Solana ETF approval and the introduction of basket products. This development could drive increased trading volumes and volatility across altcoins, with Solana likely to see the most significant short-term impact. The report underscores the importance of monitoring SEC movements and ETF application timelines for informed altcoin trading strategies. (Source: @EricBalchunas, Twitter, June 10, 2025)
