Multiple altcoin networks have collectively raised about $2.6 billion, but on-chain activity remains minimal, with low transaction fees raising concerns about their sustainability. Analyst Nick Valdez pointed out that Celestia (TIA) has only around 1,200 daily active users and continues to face technical obstacles; Sei (SEI) has approximately 7,000 daily active users, but its daily transaction fees are only about $232. Monad, due to its supply of 100 billion tokens, faces significant token unlock risks; Sonic (formerly Fantom) experiences low fees and is under selling pressure. Algorand (ALGO), despite its low fees, maintains about 26,000 active addresses and shows a potential bullish technical pattern, indicating a possible rebound.
