Bitcoin stabilizes above $66K as SIREN jumps and PI rebounds

Bitcoin traded steadily above $66,000 for about 36 hours after rebounding from Friday’s four-week low near $65,500. Bitcoin’s range stayed relatively calm versus earlier volatility that saw BTC slide from around $72,000 to the $65.5K area, then recover on stabilization rather than a breakout. During the same period, broader market momentum looked muted. Total crypto market cap hovered near $2.370T, while Bitcoin dominance slipped to about 56% (CoinGecko), suggesting capital rotation away from BTC or slower follow-through across majors. Large-cap altcoins largely mirrored Bitcoin’s cautious tone: ETH, XRP, SOL, and DOGE were slightly lower, while BNB, TRX, BCH, XMR, and HYPE recorded modest gains. No strong directional consensus formed by Sunday. Smaller-cap action stood out. SIREN surged another ~13% in 24 hours to around $1.80 after a highly volatile week that ranged from roughly $3.60 down to near $1.00. Pi Network’s PI also rebounded, rising over 3% and trading near $0.18 after slipping below ~$0.175. Key levels and figures: BTC held ~$66.7K at the time of reporting, with the 24h low/high around $66.3K/$67.2K. The mixed market breadth and slipping dominance point to a choppy, range-bound setup where traders may favor tactical altcoin momentum while monitoring Bitcoin for confirmation.
