Bitcoin veteran Adam Back has criticized Cardano, dismissing its academic contributions as mere marketing rather than genuine innovation. Back, who is mentioned in the original Bitcoin whitepaper, expressed skepticism about Cardano's value proposition. In contrast, price analyst Ali Martinez has identified a potential rally for Cardano's ADA token, predicting a price target of $2. Martinez's analysis is based on technical indicators that suggest a bullish trend for ADA, despite the criticism from Bitcoin proponents.
