Two altcoins, CORE and COTI, posted sharp intraday rallies on September 17, 2026, even as broader cryptocurrency market conditions remained mixed.
CORE jumped 8.98% in just five minutes, climbing to $0.52452 from around $0.481287. The token recorded a 24-hour gain of 10.95%, with an intraday low of $0.471517 and a high of $0.52452. Traders noted that reported trading volume was unusually thin, which could raise questions about the sustainability of the move. Key levels being watched include resistance near $0.54 and support near $0.50.
Later in the day, COTI surged 10.31% in a single hour, moving from $0.02086 to $0.02301. Over 24 hours, COTI gained 31.56%, with trading volume reaching approximately $9.64 million. Its daily range spanned from $0.01691 to $0.02301. No confirmed project-specific catalyst was identified, though traders pointed to potential macroeconomic factors such as interest-rate expectations and dollar strength as possible drivers of speculative demand.
Both moves appear driven primarily by short-term positioning rather than major protocol announcements. The rallies may attract momentum traders, but the absence of confirmed catalysts suggests caution. Resistance for COTI is seen near $0.02301, with support around $0.021.
