The analysis of ADAUSD on the weekly chart suggests that the cryptocurrency has completed a three-wave corrective downtrend and is currently trading near a key Fibonacci support level around 26.79 cents. While the immediate outlook is bearish, the price is expected to attempt a reversal and potentially form a larger wave four bounce. However, confirmation of a bullish trend continuation will require a break above the recent swing high. Any price action below the support level of 21.22 cents would invalidate this bullish scenario.
