Three altcoins—Decred, Polygon, and Optimism—are displaying varied technical indicators as the weekend trading period approaches. According to NS3.AI, Decred is showing strong bullish momentum after successfully reclaiming a key support level. In contrast, Polygon and Optimism have reached new all-time lows due to persistent selling pressure. Despite this, subtle bullish divergences in Polygon and oversold signals in Optimism indicate potential recovery opportunities if there is a shift in market sentiment.
