According to Cas Abbé (@cas_abbe) on Twitter, multiple Altcoin ETFs are anticipated to be approved by the SEC in Q3 or Q4 of 2025, as most applications have final deadlines during this period (source: Twitter/@cas_abbe, May 3, 2025). The approval of these ETFs is expected to trigger significant institutional investment into altcoins, which could impact trading volumes and price momentum across major altcoin markets. Traders should monitor the SEC decision timeline and be prepared for increased volatility and liquidity as institutional flows enter the altcoin space.
