Cardano (ADA) experienced a 7% increase on Sunday, reaching $0.376 as traders focus on the $0.427 resistance level. The cryptocurrency maintains its position above the crucial support level of $0.34, which is influencing short-term market sentiment. Despite a 10.97% decline in December, ADA shows potential for a rally before the end of the year. Market speculation is further fueled by a potential 2026 ETF filing currently under review by the SEC, which could impact Cardano's price trajectory. Investors are closely monitoring these developments as the year draws to a close.
