Cardano (ADA) surged nearly 9%, now trading around $0.70, eyeing the key resistance at $0.80. On-chain data from Santiment shows whales accumulating ADA during the recent dip. Coinglass metrics, including a positive long/short ratio and funding rate, confirm bullish sentiment. If ADA breaks above the 200-day EMA at $0.71, the rally could extend. A close below $0.61 would invalidate the bullish setup.
