Multiple altcoin networks have accumulated approximately $2.6 billion in financing, but on-chain activity is extremely sparse, with depressed transaction fees, raising concerns about their sustainability. Analyst Nick Valdez specifically highlighted that Celestia (TIA) has only around 1,200 daily active users and continues to face technical resistance; Sei (SEI) has approximately 7,000 daily active users but only generates around $232 in daily fees. Monad faces enormous token unlock risks due to its 100 billion token supply; Sonic (formerly Fantom) suffers from depressed fees and faces selling pressure. Algorand (ALGO), despite low fees, still maintains approximately 26,000 active addresses and exhibits a potentially bullish technical pattern, suggesting possible recovery ahead.
