Cardano (ADA) has significantly increased its market dominance, rising 5.63% in the past 24 hours, bringing its market share to 0.9%. This growth reflects strong investor interest, particularly regarding ADA's long-term growth, which has increased by 74.79% in six months and 80.61% in five years. Key factors include network upgrades, such as the Valentine's Day update, and increased institutional interest in Ethereum competitors. ADA's dominance may signal the beginning of altcoin season, where funds will flow from Bitcoin to major altcoins.
