HTX Weekly Review: Altcoin Market Gains Momentum as PHA Leads Weekly Performance

During the week of September 21–27, Bitcoin's rebound toward $87,000 spurred capital rotation into mid-cap assets, pushing the Altcoin Season Index to a three-month high. HTX data shows strong performance across AI, L1, DeFi, and meme coin sectors. PHA led the gains with an 83% increase, followed by GRASS (71%), SEI (51%), and SUI (46%). Notable developments included Canary Capital's S-1 filing for a staked SEI ETF and CME Group's announcement of upcoming UNI futures. Meanwhile, BSC-based meme coins like MUBARAK and MARSCOIN also saw significant, albeit volatile, price action.
