SIREN, a top-performing altcoin, has surged by approximately 2,450% over the past 90 days, with an additional 11% gain in the last 24 hours. Despite this impressive rally, the asset faces underlying risks as its on-chain fundamentals deteriorate. The number of SIREN holders has decreased from an all-time high of 41,570 to 39,390, leading to a $490 million drop in market capitalization. The rally is primarily driven by perpetual traders increasing long positions, with the Taker Buy/Sell Ratio remaining above 1, indicating strong buy-side pressure. However, the Funding Rate has turned negative at -0.0687%, suggesting a shift towards bearish sentiment. This divergence between market activity and fundamentals introduces significant risk, potentially leading to a reversal in SIREN's price trajectory.
