The cryptocurrency market is at a critical point anticipating a new growth phase in September 2025. Investors are looking for the best altcoins to buy.
XRP: Recovery with Whale Buying Power
On August 21, 2025, XRP experienced extreme fluctuations but managed to rebound by 6%, reaching $2.93 after a drop to $2.82. Trading volume surged to 155 million, nearly three times the daily average. The resolution of the Ripple-SEC lawsuit has lifted a years-long uncertainty from XRP, and the accumulation of nearly **900 million tokens in 48 hours** indicates strong confidence. Analysts predict XRP could rally to **$8.50–$9** by Q4 2025.
Solana: ETF Impact and Alpenglow Upgrade
Solana (SOL) is trading at **$187.27**, up 6.16% in the past 24 hours. The network is preparing for its **Alpenglow consensus overhaul**, which will reduce block finality to **100–150 milliseconds**. Nine Solana ETF filings are due for their final SEC decision in October 2025, and if approved, prices may reach **$225–420**. Strong fundamentals and institutional demand position Solana as a promising altcoin.
Cardano: Legal Wins and Ecosystem Growth
Cardano (ADA) has rebounded to **$0.88**, with whales adding over **130 million ADA** during the pullback. Technical setups indicate a potential **golden cross**, which historically led to gains exceeding 200%. Predictions suggest that ADA could reach **$2–$8+** in the next cycle. The **Cardano ETF** application by Grayscale is showing over **90% approval odds**, adding further excitement.
As September approaches, the cryptocurrency market is gearing up for another bullish leg. XRP’s recovery, Solana’s upgrades, Cardano’s ETF momentum make them key assets for investment in the near term.
