Price initially rallied from support in the $0.30-$0.32 range, backed by an upward-sloping 100-period moving average that signals sustained momentum.

However, the subsequent breakout above the channel’s upper boundary, followed by a successful retest and rebound, confirms a bullish continuation pattern.

Should momentum persist, price targets include resistance levels at $0.3828, $0.4009, and potentially $0.4229.
