Cardano (ADA) has experienced significant whale accumulation and renewed institutional interest, with large holders purchasing approximately 70 million tokens. The cryptocurrency was recently re-added to the Hashdex NASDAQ Crypto Index U.S. ETF, providing institutions with fresh exposure to ADA. Analysts have observed increased whale activity and a positive shift in market sentiment, as ADA approaches a resistance level near $0.87. While price momentum and trading volume indicate the potential for a breakout, experts warn that a failure to surpass this resistance could result in continued sideways trading.
