Cardano's largest holders have amassed over 64% of the ADA supply, marking the highest concentration since 2017, according to on-chain data from Santiment. Wallets holding at least 1 million ADA, valued at approximately $230,000, have increased their stake to 25.11 billion ADA. This accumulation trend has persisted since 2024, despite a broader crypto market downturn. Santiment highlights that such accumulation by key stakeholders often signals confidence, though it also poses concentration risks. Historically, similar patterns have led to significant market impacts when large holders decided to sell. Currently, ADA is trading at around $0.23, reflecting a 6% decline over the past week, as the market watches these large holders' next moves closely.
