In mid-April, the cryptocurrency market experienced a significant rebound. While Bitcoin remained volatile at around $74k, altcoins collectively strengthened, with many tokens recording double-digit or even multiple-fold gains within seven days. RAVE surged over 4,000%, Srien increased by 51%, DEXE rose by 40.7%, and WLD, AAVE, ENA, among others, also performed well. The Altcoin Season Index rose from 32 to 37, indicating clear signs of capital rotation, with Meme, AI, and infrastructure sectors leading the gains. Although it was not a broad-based rally, market sentiment warmed, risk appetite returned, and the strong rebound of altcoins may signal the arrival of a new bull market phase. Investors should remain cautious of volatility and adopt a rational approach.
