The sharp decline in Cardano's price over the past 24 hours is likely to have a negative short-term impact on ADAUSD. Despite the recent weekly gains, such a significant drop could trigger a bearish sentiment among investors. The increased trading volume suggests that the price movement is backed by substantial market activity, which could either indicate a sell-off or increased interest at lower price levels. The rise in circulating supply could also put downward pressure on the price if demand doesn't keep up.
