Well cash retains its dominance in many parts of the world due to stability and universal acceptance, while in my opinion cryptocurrency is rapidly gaining traction as a futuristic alternative. Its decentralized nature, potential for financial inclusion, and technological advantages make it appealing, particularly in the digital economy. The choice ultimately depends on individual needs, technological infrastructure, and regional preferences. As the world moves toward digitalization, crypto is poised to challenge cash’s throne, but for now, cash remains the king in traditional transactions.
